Case Study: Insurance Australia Group (IAG) achieves faster, more resilient and scalable collaboration with Atlassian Confluence (Data Center on AWS)

How IAG created a stronger, more resilient workplace by optimizing and shifting to Atlassian Data Center

Insurance Australia Group (IAG), a major financial-services firm with more than 12,000 Atlassian users, was straining under a growing, server‑based Atlassian footprint that hurt speed, reporting and governance. With plans to move to the cloud but needing an immediate, controlled fix, IAG sought an interim approach to improve performance and prepare the organization for a future cloud migration.

IAG took an “optimize and shift” approach: cleaning and standardizing instances, cutting configurations by 80%, archiving 47% of Jira projects and more than 66% of Confluence spaces, then migrating to Atlassian Data Center on AWS. The upgrade delivered zero‑downtime upgrades, instant project provisioning (vs. days), improved stability, scalability and reporting, and saved the business over 100 hours in under a year while positioning the team to move to Atlassian Cloud when ready.
