API / APIGEE Gateway Interview Questions
What is the Apigee organisation hierarchy and what are Environments?
Apigee uses a clear hierarchical structure to organise all resources. Understanding this hierarchy is essential for managing multi-team and multi-environment API programmes.
| Level | Name | Description |
|---|---|---|
| 1 (top) | Organisation | Top-level container; one per GCP project; holds everything -- proxies, products, developers, environments |
| 2 | Environment | A deployment boundary (e.g. dev, test, prod); proxies must be deployed to an environment to receive traffic; each has its own URL |
| 3 | API Proxy | The deployable proxy bundle; deployed to one or more environments |
| 3 | API Product | Business package; references environments and proxy resource paths |
| 3 | Developer / App | External developers and their registered applications |
# Typical environment setup: # # Organisation: my-company # |-- Environment: dev (https://dev.api.example.com) # |-- Environment: test (https://test.api.example.com) # |-- Environment: prod (https://api.example.com) # # Proxy deployed to both test and prod: # gcloud apigee deployments create \ # --organization=my-company \ # --environment=prod \ # --api=orders-proxy \ # --revision=3 # Environment-specific configuration: # - Target URLs different per environment (dev points to dev backend) # - Quotas may differ between test and prod # - Different SSL certificates per environment # - KVM (Key Value Maps) scoped per environment for config values
Key point: the Apigee Organisation is NOT the same as the Google Cloud Organisation. It lives inside your GCP project and contains all your environments, APIs, products, and developer registrations. When you deprovision Apigee API hub, it also deletes associated Apigee organisations if they have no Apigee instances.
