Using Confluence Clustering with Amazon Elastic Container Service

[Ben Freke]

Hello,

We're hoping to deploy Confluence Data Centre on Amazon's Elastic Container Service. There are several benefits to this, including the use of Fargate.

Upon development of a proof of concept, we have discovered that the Hazlecast service used for Clustering on AWS is not configured to support ECS, so it tries to find EC2 instances and then causes Confluence to fail.

There was a Jira issue that was closed a few days ago with no updates on it. Has this bug been resolved? 

We would like to have a scaling and self-healing cluster of Confluence in AWS, but it appears that with the other options of Multicast (not supported in the VPC configuration we have) and specifying IPs prevent us from acheiving the true scalability we can have with other services like Jira.

I also see Bitbucket is similar to Confluence in its use of Hazlecast and limited support for ECS.

Hazlecast now supports ECS, have/will Atlassian be utilising this support?

Thanks,

Ben

I had an answer to this - ECS support isn't on the Atlassian roadmap but instead Kubernetes is - https://jira.atlassian.com/browse/SCALE-11
