From firefighting to future-proofing: Atlassian’s journey with a multi-account strategy - Work Life by Atlassian

Atlassian implemented Account Sharding to improve platform stability, accelerate development, and future-proof their infrastructure. The changes included separating compute workloads from resources, simplifying IAM access for cross-account cases, and establishing a single source of truth for partition allocation. The project resulted in reduced deployment duration by 5 times, increased overall platform stability, and enabled the delivery of new regions in just 2 months.
