The Big Picture: Your Migration Journey An overview of the 12-step migration process, from assessment to post-cutover cleanup. Step 1: Assess Your Current Situation Gather details about your application, including runtime environment, resource requirements, external integrations, and traffic patterns. Step 2: Choose Your Target Platform Select the right GCP service for your stateless application: Cloud Run, Google Kubernetes Engine (GKE), or Compute Engine. Step 3: Prepare Your Code and Container Dockerize your application, add health endpoints, and push your container image to Artifact Registry. Step 4: Infrastructure as Code Automate your infrastructure setup using Terraform to ensure repeatability and consistency. Step 5: Build Your CI/CD Pipeline Set up a CI/CD pipeline using Cloud Build to automate testing, container builds, and deployments. Step 6: Networking and IAM Configure networking with Serverless VPC Access and set up IAM roles following the principle of least privilege. Step 7: Secrets and Configuration Securely manage secrets using Secret Manager and handle non-sensitive configuration with environment variables. Step 8: Observability Set up logging, monitoring dashboards, and alerts to ensure visibility into your application's performance and health. Step 9: Staging Validation Deploy to a staging environment, run smoke tests, load tests, and security scans to validate your application before production. Step 10: Blue/Green or Canary Deployment Implement gradual rollouts using canary deployments to minimize risk during cutover. Step 11: Cutover Execute the cutover with minimal downtime, including DNS TTL adjustments, traffic shifting, and intense monitoring. Step 12: Post-Cutover and Cleanup Monitor for stabilization, optimize resources, enable autoscaling, and decommission old infrastructure. Rollback Plan: When Things Go Wrong Prepare for potential failures with a clear rollback plan, including triggers, immediate actions, and rollback execution.Final Thoughts
Migrating stateless workloads to GCP is a methodical process that combines planning, automation, and observability. This conclusion reinforces the importance of starting small, building confidence, and embracing cloud-native principles.
