Atlassian is rearchitecting Jira Cloud to enhance its performance and reliability. By transitioning to a cloud-native, multi-tenant platform, the team aims to improve scalability and address the limitations of the previous architecture. Key changes include optimizing data access patterns and decoupling services for better efficiency.

Atlassian is transitioning to a cloud-only model by discontinuing its datacenter products, including Jira and Confluence, which will face end-of-life deadlines. While many customers are already on the cloud, concerns about integration issues and potential cost increases have emerged, particularly for those with legacy systems. Migration options are available, but not all users will benefit financially from the shift.
