A Public, Private, or Hybrid Cloud?

By 5 Mins Read
A Public, Private, or Hybrid Cloud? Which is the best for you?

All clouds are not created equal, and generic references to cloud may be confusing.  Just like all automobiles are not the same, not are all clouds the same.  

There are essentially three types of clouds:

  • Private
  • Public
  • Hybrid 

Each has its own benefits and drawbacks as will be discussed below, and sometimes the confusion related to clouds is based on lack of a clear definition.

Private Cloud

Private cloud refers to on-premises infrastructure that may be housed within the enterprise or within a segregated space in a co-located data center.  The servers and hypervisor resources deployed in this type of data center are dedicated solely to a single enterprise.  Within a private cloud environment, IT is fully responsible for the hardware, software, networking, monitoring, and maintenance.

Private clouds have the benefit of being highly customizable.  If an organization has unique requirements, IT has full authority to alter computing systems as they see fit.  The downside is that costs can spiral out of control, especially within organizations that are decentralized.

With a private cloud, expansion and contraction present challenges.  For example, if additional resources are required in order to address a busy season or fewer resources are needed during slow times, the enterprise must provision equipment based on peak requirements, plus an element of redundancy.  As such, the total cost of ownership is higher due to idle resources.

Disaster recovery is more complex and expensive with a private cloud infrastructure.  Duplicate system resources are required at a secondary site that go unused during normal operations.  As a result, the costs for a disaster recovery site with a private cloud cost are doubled.

Public Cloud

Public cloud is gaining in popularity as providers–such as Azure, Amazon Web Services, and Google Cloud Services–offer fixed costs for hosted resources.  Enterprises have a clear understanding of the costs for utilizing each type of resource and can accurately predict monthly utilization fees.  In addition, there are no surprise costs for maintenance or equipment replacement.

Referring to the example of an enterprise that experiences peak and slow seasons, public cloud services are optimal from a cost standpoint because resources are only enabled when necessary.  This can represent massive savings.  

By offering compute resources within a shared infrastructure, complexity is reduced and scalability is improved.  IT staff no longer needs to request and order new hardware, place it in server racks, install networking equipment, ensure proper cooling levels in the data center, and similar work effort.  Instead, an IT professional just selects the desired resource from an administrative interface, and the resource is quickly deployed.  Public clouds enable IT to be extremely agile.

When testing new applications or processes, running a Proof of Concept (PoC) in a cloud environment is fast and easy.  By simply designating the compute resources, testing can commence in short order to prove or disprove a new concept.

Public cloud systems require a new skill set for IT staff.  While the administrative interfaces are generally intuitive, there are many unique technology features to each public cloud that must be absorbed by the IT staff.  Also, each public cloud uses slightly different terminology and processes, so there is a learning curve for each public cloud.

A key downside to a public cloud infrastructure is lack of control of backend systems.  When an entire site or public cloud provider experience issues, all tenants may be impacted.  While Service-Level Agreements (SLAs) guarantee high uptime, system interruptions do occur from time to time.

Hybrid Cloud

Private clouds and public clouds each have unique benefits, and enterprises can opt to take advantage of the best of each by adopting a hybrid cloud solution.  While it may take a bit more work effort to ensure full integration and access, the flexibility, cost, and reliability gains are significant.

For example, an enterprise may elect to continue operating an on-premises data center and utilize a public cloud for disaster recovery.  With this solution, a secondary site does not need to be allocated.  Thus, DR site resources are not billed until needed, so the total cost of ownership is significantly lower.

One downside to a hybrid cloud environment is that IT staff must be thoroughly familiar with both clouds and be able to determine which cloud is best suitable for each circumstance.  This may necessitate additional training and perhaps even more IT staff.  

Which Cloud is Best?

Although hybrid is often selected as the optimal solution, such is not always the case.  Most organizations have moved or are in the process of moving at least some of their compute infrastructure to a public cloud.  However, some are choosing to continue exclusively with a private cloud, and others are moving all system resources to a public cloud.

Cost and functionality are key drivers in determining which cloud is most suitable.  Because all clouds are not created equal, each enterprise must delve into the benefits of each type of cloud to determine whether private, public, or hybrid cloud is the best solution.

Empowering Remote Workforces with the Help of Virtual Desktops

Successfully empowering a remote workforce is more important than ever. Today’s remote employee requires the same performance, access and security as they would working out of the corporate office. Traditional methods of supporting remote employees using local desktop operating systems, applications and VPN connectivity leads to inconsistent and inefficient computing experiences. Let’s learn how Anunta’s virtual desktops can provide a better computing experience for the remote workforce.
Better Security
Considering all the high-profile cybersecurity incidents of late, it’s no wonder businesses are constantly on the lookout for the most secure technologies to protect applications and data from bad actors. Anunta Tech powered virtual desktops are built on a cloud infrastructure that was engineered with security as a top priority. Because the virtual desktop and all applications/data are hosted within an industry-best cloud infrastructure such as Azure or AWS or Horizon, virtual desktop users can be sure that their data is protected regardless of where a remote employee is working from.
Additionally, businesses that must adhere to strict regulatory standards will be happy to know that Anunta’s cloud desktops are fully PCI, HIPAA and SOC2 compliant. This fact eliminates any hurdles that may have gotten in the way of some businesses or healthcare organizations migrating to virtual desktops. Regardless of what compliance requirements your market vertical must observe, Anunta raises the bar when it comes to data security.
Improved Network Performance
Nothing is more frustrating than trying to work in an application that’s exceptionally slow. For remote workforces, this is unfortunately more common than it needs to be. The primary reason is that remote user network data flows are often poorly optimized. This creates added latency to the application, negatively impacting the end-user experience. Forcing users through VPN tunnels is the most common reason for poor remote workforce network latency. While secure, VPN tunnels often force all traffic into the corporate network prior to redirecting it to the application or database server the end user is attempting to access. This creates suboptimal network paths, increasing network latency.
Anunta’s Cloud Desktops largely eliminate the need for remote access VPN’s. Not only does this simplify remote workforce access to apps and data, but it also eliminates unnecessary latency due to VPN tunnel hairpins.
Delivering a consistent desktop experience
Even during the 2020 pandemic, many businesses allowed employees to operate in a hybrid workplace environment. This means that employees may work inside the corporate office one day – and out of their home the next. Being able to deliver a consistent desktop experience in both environments greatly enhances an employee’s ability to perform their work duties. As such, a platform that virtualizes the desktop experience both in and out of the office is an increasingly important feature to have.
The beauty of Anunta’s Cloud Desktop is that it performs identically no matter where a user resides. Thus, end users do not have to modify their work processes or habits as they shift between in-office or work-from-home settings.
Flexible access
When you ask remote workforces what their top needs are from a technology perspective, flexible access to apps and data is always at the top of their list. Not only do Anunta’s virtual desktops allow users to connect from any location – they also let the users connect to virtual desktops using a wide range of endpoint devices. This includes support for Windows PC’s, Macs, Chromebooks and even Apple iOS and Android smart devices.
Remote workforce technologies — part of a business’s strategic IT plan
The 2020 pandemic played a major factor in advancing an IT department’s need to improve access, security and performance of business applications. But even as some business leaders plan to eventually bring employees back into the corporate office, understand that the need for remote workforce technologies have become a critical part of a business’s overall business continuity and disaster recovery (BCDR) plan. The future of business will demand that employees be able to access apps, services and other digital resources in a safe and efficient manner no matter where they reside. That’s why it’s so important to properly plan and architect for this level of remote workforce flexibility in 2021 and beyond.

The Future of Work and Workplace

By 5 Mins Read
The Future of Work and Workplace | Virtual Desktops

As we embark on a new year, what lies ahead for new technologies, and what will be the impact on the workplace?  Will 2021 introduce incremental changes or will ground-breaking technologies profoundly and quickly impact the workplace?

2020 in Review

First, let’s take a brief look at the technical changes that occurred over the past year.  Of course, Covid-19 abruptly changed how we work, and it forced the adoption of new computing technologies.  In particular, workers were thrust into working from home, as well as altered ways of collaborating with business colleagues.  Some businesses expanded exponentially, whereas others declined.

As we look back at 2020, the single most impact from an end-user computing standpoint was the result of Windows Virtual Desktop (WVD) gaining in popularity.  Although WVD was actually released in late September 2019, the first few months were largely evaluation and testing, not actual adoption.  

While virtualization technologies have been available for over 20 years, the combination of cloud-based infrastructure, advantageous licensing, and Covid-19 caused many small- and medium-sized businesses (SMBs) to adopt the WVD in 2020.  

As Anunta approaches a decade of providing end-user virtualization technology services, we have worked with our customers to marry the right technical capabilities with business needs.  We have seen firsthand how small businesses have been able to transform themselves with the adoption of better IT services.  

What’s Next?

As small businesses continue to represent a critical pillar in the economy, the creation and growth of this business segment will draw even more attention in the future.  Small businesses have unique needs, particularly from a user computing standpoint.  However, many small businesses struggle culturally between the desire to “do it all,” versus outsourcing IT services.  Going forward, more and more small businesses will accept IT service providers as the optimal solution, especially in light of how the workplace will continue to morph in the future. 

Virtual desktops are a key enabler to a more efficient workplace.  Whether the virtual desktops are provided by Microsoft or VMware or Citrix, or another technology, the ability for users to securely access enterprise resources from anywhere and via any device removes many of the hindrances of traditional computing.  The user device is largely irrelevant, i.e., access is not dependent upon a particular piece of hardware.  Thus, whether users access enterprise resources via a corporate-owned device, a home computer or tablet, or even a large mobile device, so long as an internet browser can be opened, the virtual desktop can be accessed. 

Remote Working

Remote working has transformed the culture of many workers, and employers will more concretely realize cost efficiencies related to office space, as well as increased productivity due to the elimination of commuting time.  According to a recent Gallup poll, “Nearly two-thirds of U.S. workers who have been working remotely during the pandemic would like to continue to do so.”   Even after Covid-19 subsides, many employers have openly stated that the traditional office will not be revived.  For some, this means working from home permanently.  Where some face-to-face collaboration is required, this will translate to unassigned office hotdesks with thin clients or generic devices when visits to the office are necessary.  Whether the employee works from home or a hotdesk, the virtual desktop will provide the underlying technology that makes it feasible.

Security

There will be an increased emphasis on system security.  As much as employers want to provide secure remote access, bad actors continue to proliferate and will become even more creative in the future.  This challenge is even more critical for small businesses that are not savvy to these intruders.   

Accessing the virtual desktop requires optimal security and analytics.  While SSL/TLS security is a standard feature of virtual desktop sessions, we can expect to see even higher security, intelligence features, and analytics integrated into user access.  Cloud technologies inherently incorporate built-in security, and we can expect artificial intelligence to play a larger role in the behind-the-scenes security.  Security Information and Event Manager (SIEM) intelligence will be further optimized and become even more critical detecting system threats.

Government and industry compliance requirements will continue to affect what businesses can and can’t do.  Health care and banking already have a myriad of security requirements, such as password compliance, and it is reasonable to assume that these compliance requirements will continue to increase in complexity.   The downstream impact falls onto not just the IT organization, but also individual users.  Virtual desktop service providers, also known as Desktop as a Service (DaaS) providers, such as Anunta, are engaged by numerous end customers in various industries, and those outsourced systems often supersede compliance requirements without special requests.

Affording the Future

Of course, the price tag factors into the technologies that enterprises will adopt in the future.  The price for computing services must align with pre-defined budgets and not represent an exorbitant increase in costs.  DaaS providers fully recognize this; in addition, competition and technical advances force this commercial alignment.  

Wrap-Up

The workplace of the future simplifies how we work. It is based on the ability to securely access enterprise resources from anywhere, on any device, at any time, and at a reasonable cost. While this is basically available today, we can expect a surge in security and system enhancements that further drive the value of DaaS.

VDI or DaaS – Which Should You Pick

By 5 Mins Read
VDI v/s Daas - Which one should you pick

VDI or DaaS – Which Should You Pick?

VDI is to DaaS what a screw is to a nail: Both solutions can be used to achieve similar goals, but they work in different ways and cater to different needs.

If you’re struggling to decide whether VDI or DaaS is the best solution for your business, read on. Below, we walk through the similarities and differences between DaaS and VDI and explain what to pick for which situation.

What is VDI?

VDI, which stands for Virtual Desktop Infrastructure, is a technology that hosts virtual desktop sessions on a central server, then allows users to connect to those sessions from remote devices over the local network.

A typical VDI setup involves using Windows Server to host several remote desktop sessions. Then, users who want to access those sessions use a tool like the Windows Remote Desktop client app to connect.

That said, VDI is a generic term. You don’t have to use Windows Server to build VDI infrastructure. You could use a standard Windows desktop machine to host virtual desktop sessions, too, although that approach is less common. You could also build VDI infrastructure using Linux PCs, if your organization prefers Linux over Windows.

What is DaaS?

DaaS stands for Desktop-as-a-Service, a type of solution in which virtual desktop environments run in the cloud, with each environment hosted in a dedicated virtual machine. Users can log into these environments, which are sometimes called cloud desktops, from anywhere on the Internet, not just a local network.

Like VDI, DaaS can be implemented in a variety of ways. Windows-based cloud desktops are most common, but Linux desktops can run in the cloud, too.

There are also different types of clouds that can host cloud desktops. They can run in a general-purpose public cloud like Amazon Web Services or Microsoft Azure. Or, they could be hosted in a cloud platform dedicated just to DaaS.

Differences between VDI and DaaS

From the end-user’s perspective, VDI and DaaS deliver mostly — but not totally — the same experience. Nonetheless, there are crucial differences between VDI and DaaS:

  • Network setup: In a VDI-based environment, virtual desktops are accessed via the local network from devices that are either physically present on the network, or are connected to that network via a VPN. In DaaS, the public Internet provides the network connection between remote devices and virtual desktop environments. Users can typically connect to a DaaS service from anywhere, without having to use a VPN.
  • Desktop session type: In VDI, desktop environments run as virtual sessions on the same host operating system. In DaaS, they run as distinct virtual machines. This means that DaaS provides a higher degree of isolation between desktop environments.
  • Deployment time: Because VDI infrastructure must be set up on a company’s physical site, it typically takes longer to deploy VDI than a DaaS service, which can be made available in as little as a few hours.
  • Scalability: It’s easy to add and remove cloud desktops from a DaaS platform at will. Scaling VDI infrastructure up or down takes longer, because it requires adding or removing physical on-site servers.
  • Historical popularity: Although both VDI and DaaS solutions have been available for years, VDI has historically seen higher rates of usage in enterprise environments. DaaS is now becoming very popular as well, however, and may overtake VDI in popularity in the coming years.

VDI vs. DaaS: What to choose when

Again, VDI and DaaS deliver a similar end result: Desktop environments that users can access from remote devices. However, one solution is likely to prove better than the other, depending on the company’s needs.

VDI works best if the following is true:

  • Most users will connect to desktop sessions from the local network. Although VDI sessions, as noted above, can be accessed from off-site using VPNs, this adds a layer of complexity that makes VDI less than ideal when the majority of users are off-site.
  • Network performance is a priority. Because VDI sessions are delivered over the local network, they generally offer higher rates of bandwidth and faster response times than DaaS. That said, DaaS services running on modern infrastructure are quite responsive, too.
  • The business already has servers available to host VDI sessions or is able to make the capital investment necessary to acquire them.
  • The risk of disruptions to local infrastructure (due to factors such as loss of power or natural disasters) is minimal.

Meanwhile, DaaS is ideal under the following conditions:

  • The business requires dedicated, isolated desktop environments for each user.
  • It’s a priority to maintain access to desktop environments even if the business’s local infrastructure is disrupted by events like natural disasters. Because DaaS hosts desktop environments on remote cloud infrastructure, the environments are not harmed by disruptions to local infrastructure.
  • Users require a simple, turnkey solution for connecting to their remote desktop environments without having to install special software (like VPN and RDP clients).
  • The number of desktop environments that the business requires is likely to fluctuate or grow quickly over time. Because DaaS services are easier to scale, they are a better fit for this situation.

Is IT Prepared for a Hybrid Remote Workplace Environment?

Is IT Prepared for a Hybrid Remote Workplace Environment?

Is IT Prepared for a Hybrid Remote Workplace Environment?

The COVID-19 pandemic has placed remote work squarely in the spotlight. As businesses began allowing employees to work from home (WFH) in early 2020, many IT leaders were left wondering whether remote workforces will become the long-term rule as opposed to the exception. In reality, the modern workplace has long been evolving toward a hybrid environment where employees can be productive anywhere and at any time they choose. Innovations in cloud technologies – including desktop as a service (DaaS) — have greatly accelerated this hybrid workplace capability. Let’s dig into why that is and how it can be used to better prepare your business for a hybrid work environment.

It starts with the access

At one time, corporate infrastructures were designed and built with the understanding that most employees would come into the office to perform their work duties. As such, application, network, and data security components were deployed to support this access model. While remote connectivity did exist in the form of remote access VPN, these components were designed to handle only a fraction of the overall employee headcount. Thus, major modifications were required to sufficiently support a much larger proportion of simultaneous WFH employee access.

Thanks to innovations such as IaaS and SaaS, however, infrastructure architects quickly realized that employees could directly connect to business applications and data anywhere they had internet access. The need to VPN into the corporate office has largely been eliminated as most apps and services now reside in the public cloud. This means that employees can perform their daily tasks in the office, at home, in a coffee shop or anywhere else they happen to be. This is the first step to a proper hybrid workplace experience.

Simplifying remote desktop management

While cloud computing allowed for ease of access regardless of physical location, an IT department’s desktop support team ran into other remote workforce issues. The desktop team found that they could quickly become overwhelmed when attempting to manage and/or troubleshoot corporate-deployed PC’s that were operating in WFH situations. Troubleshooting traditional desktops using remote management tools can be a time-consuming process compared to a technician having direct access to the hardware. Because of this, IT architects are beginning to leverage another cloud service – DaaS — to help them streamline desktop deployment, management and troubleshooting tasks. Not only do virtual desktops provide employees with an effective space to work within while at home or in the office – the ability to support virtual desktops in a remote or hybrid setting is also greatly enhanced thanks to DaaS.

Shared data requires centralized control

Using traditional desktop deployments, employees often can store important data and documents onto the local desktop hard drive. If a laptop is lost or stolen, this becomes a major security risk for the organization. With DaaS, however, all applications and data are kept within the service provider’s cloud infrastructure. Thus, employees can no longer save files to their local desktops. Not only does a virtual desktop architecture reduce risk from a data loss prevention (DLP) sense, but it also creates a much more uniform environment for data sharing across geographically distributed workforces. No longer will copies of files be made and splintered by remote employees. Instead, everyone is required to collaborate using a single set of stored data residing securely in the DaaS providers cloud infrastructure.

Achieving an effective hybrid workplace is closer than you think 

Whether your business plans to continue WFH strategies or begin bringing employees back into the office, having a flexible workplace will be a critical part of your organization’s overall success. Fortunately, cloud computing services grant employees the ability to seamlessly move between the office, home and anyplace in-between. While cloud computing in the form of cloud-managed apps and data are a great start, a missing component of your hybrid workplace strategy may be the desktop itself. Traditional desktop deployment models simply don’t function well in hybrid workplaces. Stand-alone desktops are too cumbersome to manage and lack important data security protections. Instead, IT decision makers should plan to migrate to a DaaS solutions like Anunta’s Cloud Desktops. This modern approach to desktop deployment is the only way to truly provide the utmost in hybrid workplace flexibility, security, and productivity.

Is the Hybrid Workplace the Future of Work?

By 4 Mins Read
Is the Hybrid Workplace the Future of Work?

According to a recent study by Stanford University, “an incredible 42 percent of the U.S. labor force is now working from home full-time”. While a large portion of us have been working from home (WFH) due to the pandemic, it’s likely that at least some employees will eventually migrate back to the corporate office once the COVID-19 situation is under control. That said, there are benefits of WFH employees – or for employees who wish to work in a hybrid workplace setting. If that’s true for your organization, now may be the time to investigate whether it makes sense to make flexible workplaces a permanent fixture. Let’s explore how hybrid workplaces are created are along with the pros and cons of this model.

Creating a hybrid workplace

From a technology standpoint, creating a hybrid workplace is more than just handing employees a laptop and giving them a remote access to apps and data. Instead, a hybrid workplace is a major architectural change from an application and service delivery standpoint. The goal for a hybrid workplace infrastructure is to provide the same level of application access, performance and security both inside the corporate network as well as outside. Most often, this requires that the IT department migrate apps, data and services to one or more public cloud service providers (CSPs). Doing so allows users seamless access to digital corporate resources no matter what location they work from.

Benefits of hybrid workplaces

A key benefit of hybrid workplaces is that they allow employees to perform their job duties from practically any location they choose. A 2020 HBR study shows that productivity can actually improve in certain professions when employees are allowed to work from home. Therefore, it may be wise for businesses to offer a hybrid environment to employees that can prosper from it. The migration of services into public clouds gives the IT department the ability to allow employees to access these resources directly instead of having to first backhaul traffic through the corporate network.

Additionally, moving to a hybrid workplace forces the IT department to implement much-needed security architecture changes to protect all users – not just those working from within the corporate office. Distributed workforce security tools such as zero trust and secure access services edge (SASE) architectures will help create a complete, end-to-end security framework with which to operate and manage a hybrid workforces.

Drawbacks of hybrid workplaces

While the benefits of hybrid workplaces are clear, it’s important to understand the potential drawbacks. For one, many IT departments continue to manage applications and data housed within private data centers. Thus, it becomes far less efficient to access digital resources while working remotely. To truly build-out a hybrid workplace architecture, migrating as many of these applications and services to the public cloud is a critical step. Failing to do so can result in suboptimal end-user experiences.

Next, some IT departments struggle with creating new end-user policies and tools that help protect the business from lost or stolen data. As workforces move outside the cybersecurity protections deployed within a corporate network boundary, data becomes much harder to monitor and track. This is especially true in situations where IT departments deploy traditional desktops and lack the necessary controls required to keep data from leaving those desktops. 

Finally, hybrid workplaces can create gaps in communication between employees and teams that previously did not exist. If changes to how employees collaborate and share data while working remote is not properly addressed, it can create significant slowdowns in productivity. Thus, processes and tools must be implemented to close this communications gap and to allow geographically dispersed employees to work in shared-data environments.

Setting the foundation for a successful hybrid workplace environment

It’s clear that hybrid workplaces are indeed the future of work. As mentioned, cloud computing plays and major foundational role in any successful hybrid workplace rollout. The cloud can not only offer uniform access for in-office and remote employees, but modern cloud security tools can also provide seamless data security as users flow between locations. Most businesses have already leveraged cloud services in one form or another. If hybrid work is your goal, it’s wise to continue migrating apps and services as quickly as possible.

Additionally, IT architects are finding that an investment in virtual desktop infrastructures (VDI) or desktop as a service (DaaS) can significantly streamline the management of hybrid workers. Virtual desktops can also help from a data loss prevention (DLP) standpoint as all data resides securely within the VDI or DaaS infrastructure. Therefore, the combination of cloud-based apps and services along with virtual desktops create an excellent foundation for hybrid workplaces both now and into the future.

What is Virtual Desktop?

By 3 Mins Read
FAQ | Anunta Tech

A virtual desktop is a thin or zero client merely relaying an image of data and applications stored remotely on a central server within a public, private or hybrid Cloud. It enables end-users with anytime, anywhere, any device access to data and applications in a remote yet secure manner.

Virtual desktops segregates desktop operating system, applications, and data from the hardware, and offers a robust, secure, flexible yet affordable solution. The Virtualization software creates desktop images and enables access to end-users over a network.

Virtual desktops are provisioned based upon user-group profiling which ensures that end-users have an uninterrupted access to role-specific applications and data via a customized interface. Since data and applications reside on a central server, management becomes simple. All bug fixes, policy and software upgrades are applied only on the centrally stored golden images ensuring security and compliance adherence for all end-users. The ability to provide consistently high application availability in an anywhere, anytime, and across any device improves end-user experience and productivity.

What are virtual desktop deployment models?

There are two models of virtual desktop deployment. These are,

  • Virtual Desktop Infrastructure (VDI):

    For organizations that have already invested in building or owning in-house data centers, VDI as a virtualization solution makes sense as it addresses the challenges in upgrading traditional physical desktops and reduces cost on IT refresh. With the data center situated in-house, organizations have full control over software, hardware and data accessed by end-users via their virtual desktops. VDI minimizes the risk of data theft or loss even if the device crashes or is stolen as all data is stored centrally on a server. However, VDI requires management of various technologies (servers, storage, networking, thin clients, and virtualization software, etc.) provided by different vendors making the implementation a complex and challenging process for organizations on their own. It also requires specialized IT skills to manage the virtual infrastructure, which adds to the complexity further.

  • Desktop as a Service (DaaS):

    Organizations that haven’t yet invested in in-house data centers, organizations that plan to have a hybrid environment or organizations that aim to move their IT spend from Capex to Opex may have greater propensity to leverage the benefits of VDI on cloud. Available as pay as you go, DaaS reduces the overall total cost of ownership (TCO) of desktop computing as the upfront spend on infrastructure is negated. Further the cost of owning specialized VDI technical skills, desktop maintenance and infrastructure depreciation is eliminated. Cloud hosted Virtual desktops are typically subscribed at a pay per user rate on a monthly basis.

What is Virtual Desktop Infrastructure?

The Virtual Desktop Infrastructure (VDI) is a virtualization technology that segregates desktop operating system, applications, and data from the hardware, and offers a robust, secure, flexible yet affordable desktop solution. The virtualization software creates desktop images and enables access to end-users over a network.

In the VDI environment, virtual desktops are provisioned based upon user-group profiling which ensures that end-users have an uninterrupted access to role-specific applications and data via a customized interface. Since data and applications reside on a central server, management becomes simple. All bug fixes, policy and software upgrades are applied only on the centrally stored golden images ensuring security and compliance adherence for all end-users. The ability to provide consistently high application availability in an anywhere, anytime, and across any device improves end-user experience and productivity.

What are the benefits of VDI?

VDI improves end user experience and productivity by:

  • Reduced costs :

    The VDI reduces the Capex involved in costly PC purchase and frequent IT refresh. The outsourced operations and pay-as-you-go model induce transparency on future requirements and helps manage Opex.

  • Anytime, anywhere, any device access to data and applications :

    As applications and data are stored on central servers, this enables access independent of the time, place and device enabling end-users enjoy flexible yet secure application availability.

  • Simplified management :

    Centralized storage of data and applications enable IT to manage desktops in an extremely efficient manner. Since user profiles are also stored centrally, rolling out OS, application and bug fixes are simplified.

  • Secure access :

    End-users only have access to applications and data specific to their roles as a result of role-based user profile creation and policy adherence. This also enables enterprises in providing contract employees and partners with secured access to relevant data and applications.

  • Rapid disaster recovery and business continuity :

    In the event of a disaster, virtual desktops can be provisioned from the centralized backup, thereby ensuring business continuity.

FAQ | Anunta Tech

What is Desktop Virtualization?

Desktop Virtualization is a technology that empowers end-users with a virtual computing environment across devices (desktops, laptops, tablets, mobile phone, etc.) and locations thereby delivering a consistent user experience. It ensures a secure, highly available, cost effective end-user desktop infrastructure wherein, end-user desktops are hosted on a centralized server, while ensuring maximum control and security over access and usage of desktops by end-users.

What are the types of virtualization?

Desktop Virtualization is not a “One Size Fits All” but requires a tailored approach to identify use case to be implemented. Organizations have the option to choose between in-house Virtual Desktop Infrastructure (VDI) or Desktop as a Service (DaaS). The different types of desktop virtualization are:

  • Session Based Virtualization :

    It delivers individual session on a virtual machine or a server where each virtual machine is shared by multiple users.

  • Non-Persistent VDI :

    It delivers a virtual machine that where sessions are not reserved or locked and can be accessed by multiple users. The desktop allows users to access their data on different PCs, as systems refresh themselves once the user has logged off.

  • Persistent VDI :

    It delivers a virtual machine like non-persistent VDI except that user sessions are reserved or locked. This type of virtual machine is designed to suit the needs of individual users.

  • Hosted Shared Desktop :
