Cloud native computing is an approach in software development that utilizes cloud computing to "build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds". Technologies such as containers, microservices, serverless functions and immutable infrastructure, deployed via declarative code are common elements of this architectural style.

- 18. 17 Virtual Gerrit Contributors Summit 2021 – On-line GerritForge.com 17 Cloud-native Gerrit : risks Losing control 1. Understand the technologies you use Team upskill, read logs, troubleshoot common problems 2. Multi-cloud Put a DR site on a different cloud, prevent global disaster 3. Allow fallbacks Design for soft-failures and fallbacks of any dependent service
- 19. 18 Virtual Gerrit Contributors Summit 2021 – On-line GerritForge.com 18 Cloud-native Gerrit : pitfalls 1. Cloud is NOT necessarily cheaper than on-prem infrastructure (see https://a16z.com/2021/05/27/cost-of-cloud-paradox-market-cap-cloud-lifecycle-scale-growth-repatriation-optimization/) 2. Do not oversize the instance types Better having *more* smaller and cheaper instances 3. Optimize cache vs. I/O throughput Memory is way cheaper than disk throughput in the Cloud (see EFS pricing at https://aws.amazon.com/efs/pricing/) 4. Use more than one availability zone, *always* Entire availability zones *may* and *do fail* 5. Ban Git/SSH, Gerrit SSH commands, SSH/stream-events SSH is stateful, difficult to trace, redirect, scale-up: *DO NOT USE IT* 6. Use auto-scaling for Gerrit read-only replicas
