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.
