TCS’ approach to migrating business applications to Google Cloud aligns organizational goals with digital transformation as a first step, enabling a balanced migration-modernization journey. The approach involves:
Re-hosting applications through migration of virtual machines using M4CE or Anthos Migrate
- Re-platforming applications by eliminating technical debt
- Re-factoring supported applications to Google Kubernetes Engine or Cloud PaaS
- Replacing applications with cloud-based SaaS applications
- Re-engineering or modernizing applications to microservices and event-driven architecture leveraging Google Anthos
TCS’ end-to-end cloud migration services comprise:
Assessing cloud preparedness: TCS offers digitized cloud assessment and defines target state to arrive at the cloud migration strategy and business case with TCS Cloud Counsel. TCS leverages Google StratoZone™ or third-party tools for discovery of enterprise infrastructure and applications to arrive at the target state for applications on Google Cloud.
Building cloud foundation: We create cloud foundation to design a scalable and efficient landing zone with TCS Cloud Mason. TCS leverages Google’s cloud-native identity and access management (IAM), network, security, consumption and monitoring enablers, and integrates with third-party tools as needed.
Driving migration with a factory-based approach: Enables reliable, secure and faster workload migration to the appropriate cloud service with TCS’ Cloud Migration Factory to meet business needs, improve operational efficiencies and perform business-as-usual activities. It involves both low-touch migration with no changes to applications, and high-touch migrations where applications are migrated to cloud-native applications. It leverages cloud-specific image migration with Google M4CE, TCS’ Cloud Exponence-based automation for environment build to re-platform and modernize, Google Anthos for migration to managed Google containers, and VMWare HCX for image migration to VMWare on Google Cloud Platform.
