🚀 Successfully Delivered a Large-Scale Migration from Google Cloud Platform (GCP) to Amazon Web Services (AWS)

Excited to share one of the most challenging and rewarding projects I've worked on—migrating a production-scale platform from Google Cloud Platform (GCP) to Amazon Web Services (AWS).

This was much more than a lift-and-shift migration. It involved redesigning infrastructure, modernizing CI/CD pipelines, migrating data and messaging services, implementing cloud-native security, and building a scalable, observable, and highly automated platform.

☁️ Core Services Migrated

Compute & Containers

• Google Compute Engine → Amazon EC2
• Google Kubernetes Engine (GKE) → Amazon EKS
• Cloud Run Functions → AWS Lambda

Databases & Storage

• Cloud SQL → Amazon RDS
• Cloud Storage → Amazon S3
• Cloud Filestore → Amazon EFS
• Memorystore (Redis) → Amazon ElastiCache for Redis
• Memorystore (Memcached) → Amazon ElastiCache for Memcached

Messaging & Scheduling

• Cloud Pub/Sub → Amazon SNS + Amazon SQS
• Cloud Scheduler → Amazon EventBridge Scheduler
• Cloud Tasks → Amazon SQS + AWS Lambda

Networking & Security

• Cloud DNS → Amazon Route 53
• GCP Networking → Amazon VPC, ALB/NLB, NAT Gateway, Security Groups
• AWS IAM, KMS, WAF, Shield, CloudTrail, and Secrets Manager

🔄 CI/CD Modernization

One of the key improvements during the migration was modernizing the deployment workflow:

• Jenkins + GitHub Actions based CI/CD
• Automated Docker image builds and publishing to Amazon ECR
• Helm-based Kubernetes deployments
• Automated deployment pipelines for Amazon EKS
• Infrastructure automation using Terraform and CloudFormation

📊 Observability

To improve visibility across the platform, we implemented an open-source observability stack for logging, monitoring, and distributed tracing:

• Prometheus
• Grafana
• Loki
• Tempo
• OpenTelemetry
• Fluent Bit

This provided centralized metrics, logs, traces, dashboards, and faster incident troubleshooting across Kubernetes workloads.

🎯 Key Highlights

✅ End-to-end GCP → AWS migration

✅ Kubernetes platform migration to Amazon EKS

✅ Database migration with minimal downtime

✅ Messaging platform migration

✅ Infrastructure as Code

✅ CI/CD automation

✅ Open-source observability implementation

✅ Security hardening and cloud-native architecture

This project strengthened my experience in cloud migrations, Kubernetes, DevOps automation, and designing scalable cloud-native platforms. Grateful to everyone who contributed to making this migration a success.

Looking forward to taking on more large-scale cloud transformation projects!
