Success Story
About the Client
Business Needs | Unifying Fragmented Multicloud Infrastructure Through Large-Scale Migration
- The client’s existing containerized workloads were independently handled across cloud accounts on AWS and GCP.
- This led to fragmented infrastructure management, inconsistent governance practices, and rising operational costs while allowing the team to function with autonomy.
- The lack of a centralized DevOps framework limited standardization in infrastructure provisioning, deployment practices, and operational monitoring across services.
- The client needed to modernize its cloud infrastructure by migrating 60+ services and databases to a centrally governed platform that could support standardized DevOps processes, improved cost control, and stronger compliance.
- The migration process also included consolidating existing data stores such as DynamoDB, RDS, PostgreSQL, and other services under a unified infrastructure and governance model.
- This large-scale multicloud migration used a hybrid strategy: lift-and-shift approach for straightforward workloads and targeted modernization for complex services.
- They expected accelerated migration execution while adhering to DevOps best practices for automation, governance, operational resilience, and cost optimization.
- The distributed cloud landscape also limited end-to-end visibility across services, making it difficult to monitor performance and maintain consistent operational oversight.
- Different teams followed varying deployment and operational practices, creating inconsistencies that hindered scalability and increased management complexity.
Solutions | Migrating and Modernizing Services to a Centrally-Governed AWS EKS Platform
- We began with a migration assessment using our DART (Discover–Assess–Recommend–Transform) framework to evaluate application dependencies, infrastructure requirements, and migration risks.
- Based on these insights, we designed a strategic migration plan aligned with the proposed hybrid migration approach and DevOps operating model.
- We migrated the services and databases to a centrally managed AWS EKS-based Kubernetes platform, enabling standardized container orchestration and governance.
- The engagement introduced GitOps-driven deployment processes, automated CI/CD workflows, centralized observability, and Infrastructure-as-Code practices to improve operational control and strengthen DevOps automation.
- The automation enabled the engineering teams to provision, modify, and validate infrastructure through code-driven workflows, reducing manual effort and ensuring reliable deployments with minimal downtime.
- Through our PIE methodology, we embedded DevOps governance using agile maturity metrics to track progress, enforce accountability, and ensure on-time delivery throughout the migration cycle.
- The solution established a secure multi-account AWS environment with VPC-based network isolation, IAM controls, and standardized governance practices, creating a scalable and resilient foundation for future growth.
- Assessed the database estate, upgraded 65+ databases, and decommissioned obsolete instances to reduce costs, simplify operations, and strengthen governance.
- Planned and executed Disaster Recovery (DR) exercises to validate backup, failover, and recovery processes, ensuring operational readiness.
- Migrated large-scale databases containing trillions of records using AWS DMS, enabling seamless data migration with optimized replication and minimal downtime.
- Migrated CI/CD pipelines from CircleCI to GitHub Actions, standardizing build and deployment workflows while simplifying pipeline management.
- Modernized the Terraform framework by upgrading legacy versions, validating provider compatibility, and resolving issues to establish a stable Infrastructure-as-Code foundation.
