The blog post describes how ClickHouse Cloud was built in under a year using an unconventional planning process.
The team prioritized simplicity and ease of use, and built the product on a shared everything architecture with separated storage and compute.
The article also delves into the design and architecture decisions, security and compliance
considerations, global scalability and reliability in the cloud, and the lessons learned along the way.
The product is deployed on Kubernetes and uses AWS Lambda, Cilium, Istio, and SQS, among other tools. Auto-scaling is built using an idler and a scaler, and the team made a conscious decision not to store Control Plane or database credentials in the service.
