How Just Eat uses tooling to deploy Go micro-services in minutes
summary
Just Eat claims engineers can scaffold, update and deploy Go microservices in minutes using an internal tool called Gokit that scaffolds services in seconds and auto-generates Terraform, OpenAPI and CI/CD. It converts a few lines of Go into service.json, provisions DynamoDB and S3, wires consumers/producers on the event bus, and outputs Prometheus/Grafana metrics. Team runs 100+ Go services for Jet Connect (handling ~800 million orders/year), uses capability tests that spin up 10–20 services, and enforces drift detection so generated changes stay consistent.
