CloudOpsHub is a growing SaaS company that provides real-time analytics to a diverse customer base across multiple regions. As their user base scales, they face challenges with manual infrastructure provisioning, inconsistent environment setups, and delayed deployments due to their reliance on traditional, non-automated processes.
The company is looking to modernize its infrastructure management and deployment pipelines. Specifically, they need to automate the creation of multi-environment platforms (development, staging, production), containerize their microservices using Docker, and build a GitOps pipeline for continuous deployment and reliable monitoring.
This blog documents the actual implementation — from initial single-file Terraform through modular refactor to production deployment with multiple live environments.
