How we finally migrated an eCommerce-Platform to GCP
summary
Lift‑and‑shift migration moves an entire e‑commerce platform to GCP using Terraform and Ansible on plain GCE VMs instead of GKE, with HashiCorp Consul service discovery plus Nomad, pgBouncer, Prometheus/Cortex, HAProxy and Kafka. The runbook migrates 200 microservices, 138 databases and 5 TB of data onto 119 GCE instances, completes the cutover in 6 hours 25 minutes (Kafka partition reassignment finishes in 50h50m), and preserves traffic routing via prepared Consul queries.
