I'm having trouble finding details on the hardware requirements and limitations for Bitbucket Data Center besides needing 3 gb of RAM and a dual processor. What are the other hardware requirements for each node (elastic search, db, load balancer, file system, applicaiton nodes)? What version of linux does data center support? Can I install data center on VMWare?
Hello Lily, welcome to the Community!
I'd be happy to go into more detail about the system requirements for Bitbucket Data Center. In general, it's difficult to quantify requirements since each installation has different usage patterns, number of users, etc.
I would recommend looking at the AWS sizing information for Bitbucket and matching the instance types back to standard terms if you're looking to run on-premise rather than in AWS. Below I'll mention the defaults our Bitbucket Data Center quickstart uses if you launch an environment in AWS using our template.
Let's look at each of your questions:
You might be able to scale down some of the resources listed from the AWS defaults depending on your users and usage patterns. However, I would err on the side of overprovisioning if you can until the usage patterns are known.
