Atlassian Engineering

Overview

Atlassian builds Jira, Confluence, and Bitbucket, the toolchain that runs the engineering process at most software companies, and operates them as multi-tenant cloud products where a single noisy customer can degrade thousands of others. The blog's strongest content covers three areas: extreme-availability case studies for the auth-and-routing layer that have hit six nines of uptime, multi-region AWS architecture with the latency-sensitive routing tradeoffs that come with it, and the still-ongoing decomposition of Confluence Cloud and sharding of Bitbucket's database out of single-tenant origins. For interviews, 'How one of Atlassian's critical services consistently gets above 99.9999% of availability' is a useful reference for high-availability design, and 'Scaling Bitbucket's Database' is a candid case study in OLTP scale-out.
