Seamless migration of client data centers to AWS cloud with a strategic approach in a phased manner.
Virtusa’s 3-phase cloud migration methodology and end-to-end execution approach gave us a competitive advantage, making us a prominent choice for being an innovative partner. Virtusa laid a phased approach for the migration process as below:
The first phase was majorly pre-planning and assessment. We initiated with a large number of applications and after detailed assessment using TOGAF-based EA Architecture modeling and SaaS-based tooling, we qualified 37 applications with ‘Lift and Shift’ approach and more than 50 applications for the second phase with a detailed roadmap and migration strategy.
The second phase involved finalizing target state design architecture and migration and validation. We built the IT Asset fact base with Automated discovery and designed the architecture model using Insight-EA. We combined Virtusa’s proven BCM approach with Insight-EA’s rich business and IT asset modeling capability, which enabled us to manage the complex business and IT transformation.
The third phase was Go Live with managed services activation, including service initialization to discovery, deployment, readiness, and closure. Virtusa managed services for this project included tools such as ServiceNow, Solarwinds, AWS, and Terraform. Currently, our team is providing ongoing support to AWS cloud for up to 3 years to ensure smooth functioning.
A few focus areas during the entire process was designed to:
- Minimize risk throughout the whole process
- Add velocity and scalability during migration
- Produce high-quality results within time and budget
- Make transitioning and cutover to the cloud efficiently & effectively
- Leveraging the economies of scale with lower variable cost
