Why teams migrate from GCP to AWS
Good fit when
- +Organizations consolidating onto AWS for breadth of services, compliance coverage, or team expertise.
- +Teams that need services without direct GCP equivalents (e.g., advanced IoT, GameLift, Outposts).
- +Companies joining an ecosystem where partners and integrations are AWS-first.
Strengths
- Broadest service catalog of any cloud provider.
- Largest global region/AZ footprint with the most compliance certifications.
- Mature marketplace, partner ecosystem, and enterprise support tiers.
Tradeoffs
- IAM is more complex: policies, roles, SCPs, and permission boundaries require careful planning.
- More architectural choices per workload category can slow decision-making.
- Pricing models (Reserved Instances, Savings Plans, Spot) require active optimization.
Migration notes
- Map GCP service accounts to AWS IAM roles and policies; redesign permission boundaries.
- Migrate data first: Cloud Storage to S3 (rclone/Transfer), Cloud SQL to RDS (DMS or dump/restore).
- Translate GCP networking (shared VPC, firewall rules) to AWS VPC, security groups, and NACLs.
- Plan compute migration per workload: GKE to EKS, Cloud Run to ECS/Fargate, Compute Engine to EC2.
- Rebuild CI/CD pipelines for AWS-native deploy targets.
