Migration Playbook: Heroku PaaS → AWS / Google Cloud (GCP)
Heroku to AWS / GCP Cloud Migration & Cost Optimization
Escape restrictive dyno limits, high add-on markups, and networking constraints by migrating to modern AWS or Google Cloud architectures.
Migration Drivers
Why companies migrate away from Heroku PaaS
Prohibitive Compute & Add-On Costs
Paying 3x to 5x cloud infrastructure markups for basic Postgres and Redis add-on tiers.
Hard Connection & Memory Limits
Hitting dyno memory limits and database connection caps during traffic surges.
Lack of Private VPC Networking
Inability to establish enterprise VPN tunnels, private peering, or strict SOC 2 network firewalls.
Execution Sequence
The 4-Phase Zero-Downtime Blueprint
Our structured migration process ensures uninterrupted production uptime, continuous data synchronization, and rollback safety.
Containerization & IaC Provisioning
Packaging applications into optimized Docker containers and defining VPCs with Terraform.
PostgreSQL Database Migration
Setting up logical replication from Heroku Postgres to AWS RDS Aurora / Google Cloud SQL with minimal cutover time.
Environment & Add-On Parity
Replacing Heroku add-ons with managed cloud primitives (ElastiCache, S3, CloudFront).
DNS Cutover & Dyno Spin-Down
Rerouting traffic through Cloudflare/Route53 with zero downtime and terminating Heroku dynos.
Risk Prevention
Pitfalls that derail this migration
Underestimating Connection Pooling
Heroku PgBouncer add-ons mask connection spikes. Forgetting RDS proxy leads to instant connection exhaustion.
Hardcoded Heroku Environment Configs
Failing to decouple DATABASE_URL runtime string changes from application connection managers.
Missing Log Aggregation
Losing Heroku Logplex streams without pre-configuring Datadog or CloudWatch log shippers.
Migration FAQs
Frequently asked migration questions
For standard web apps with a Postgres database and background queues, complete migration and testing takes 2 to 4 weeks.
Yes. We set up GitHub Actions CI/CD that automatically builds preview environments and deploys to production on git push.
