Challenges

Maintaining and managing a distributed and legacy on-premises infrastructure across data centers in Louisville, Lyndon, and Colorado (US) hosting VDI and server infrastructure for 2,500 users (with a peak concurrency of 890) in the Healthcare and Mortgage domains was tedious, time-consuming, and expensive. 

• Data center space constraints necessitated an infrastructure and technology refresh. 
• Accessing heavy business applications over the existing network caused bandwidth congestion. 
• The existing on-premise setup required significant maintenance for business continuity and was not HIPAA compliant, requiring substantial investment for certification. 

Anunta’s Solution

 Anunta facilitated a seamless migration to the public cloud by recommending and architecting a secure end-to-end managed cloud desktop solution using VMware Cloud on AWS. This leveraged the customer’s existing VMware Hypervisor environment, ensuring a smooth transition and allowing them to retain existing enterprise security, governance, and operational policies while benefiting from AWS’s scalability and security. Key aspects of the solution included: 

• Optimized Workload Sizing: Horizon VDI and server workload sizing (core, memory, and storage) was optimized for improved efficiency and performance. 
• Enhanced Connectivity: VPN was proposed for faster connectivity to the cloud environment. 
• Zero-Downtime Migration: VMware HCX was recommended and utilized for live migration, ensuring zero downtime. Virtual machines were replicated on VMware Cloud on AWS while remaining online on-premises, enabling real-time workload migration with minimal disruption and data replication. 
• Scalable Implementation: Following the initial successful implementation, Anunta facilitated the setup of additional nodes, growing from 24 nodes in FY 19-20 to 37 nodes in FY 20-21. 

Key Benefits

• Reduced Infrastructure Management: Adopting the cloud desktop solution on VMware Cloud on AWS significantly reduced the effort required for facility setup and maintenance. 
• Automated Disaster Recovery: The automated Disaster Recovery (DR) capabilities within the cloud solution lowered DR requirements and associated high maintenance costs. 
• Large-Scale User Migration: Anunta successfully migrated the workloads of 2500+ users to the cloud using VMware Cloud on AWS. 
• HIPAA Compliance Savings: The solution met necessary compliance requirements, resulting in approximately $50K in annual savings on HIPAA certification costs. 
• Eliminated Upfront Costs: The pay-as-you-go model eliminated the upfront capital expenditure (Capex) associated with hardware refresh and software purchases.
