Atlassian Data Center on AWS, from landing zone to run layer.
When Atlassian Data Center or the services around it run on AWS, Atlas Bench sizes the deployment, builds the landing zone, writes and runs the migration runbook, ties administrator access to IAM Identity Center and activity to CloudTrail, and supports the run layer afterwards.
Some estates keep Jira, Confluence, or Bitbucket on Data Center for a while longer and host it on AWS in the meantime. We size the deployment, build the landing zone under it, write the runbook that moves it, and keep it patched once it is there.
What it is
Data Center on AWS is rarely the final stop. It is where an estate waits while the app portfolio, a data residency review, or a renewal decides when Cloud happens, and that wait can outlast the project that started it. It still has to be built properly.
The shape is well understood: application nodes on EC2, or in an EKS cluster using Atlassian's Helm charts, a PostgreSQL database on RDS, shared home on EFS, and a load balancer in front. What goes wrong is decided in a hurry: instance sizes copied from the server being retired, production and test sharing one account, and database credentials nobody has rotated since cutover.
What it does
Sizing from your own load
Node counts, instance types, and database class come from the estate's real usage and Atlassian's Data Center scale guidance, not from the old server's specification.
A landing zone before the first node
Separate production and non-production accounts, private subnets for the application tier, and the network paths to your identity provider settled up front.
EC2 or EKS, chosen on purpose
Instances where the team wants hosts it can reason about; EKS with Atlassian's Helm charts where it already runs Kubernetes in production.
Where it fits
L2, platform and migration, with its access and its record held at L1 and L3. The nodes are platform. Who can administer them is answered in IAM Identity Center, and what anyone did to them is answered in CloudTrail.
What we do with it
Sizing and landing zone
Instance types, node counts, database class, and storage throughput sized to the estate, inside accounts and networks built for it.
Migration runbooks
A written, rehearsed runbook for moving from a data centre into AWS, or from AWS on to Cloud, with the cutover window and the rollback both tested.
IAM Identity Center and CloudTrail
Administrator access to the accounts assigned from your directory through IAM Identity Center, and a trail that attributes every console and API action.
Run-layer support
Upgrades, index rebuilds, node replacement, and the patch cadence Data Center depends on, handled as a standing service.
Where it earns its place
A server estate not ready for Cloud
Moving to AWS first ends the hardware dependency without forcing the Cloud decision early.
An AWS deployment built in a hurry
Production and test in one account, and an instance role that can reach far more than Jira ever needs.
