Bitbucket: Bitbucket Server vs. Bitbucket Data Center


How does Bitbucket Server differ from Bitbucket Data Center?


Server/Data Center


Bitbucket Server is a single instance of Bitbucket running on a single machine. It can only handle as much load as a single machine is capable of handling before performance degrades. If the machine goes down for any reason (for example, hardware failure, network fault, or planned maintenance), then Bitbucket Server is unavailable to users for the downtime. 

Bitbucket Data Center looks like a single instance of Bitbucket Server to users, but under the hood, it consists of a cluster of multiple machines ("cluster nodes") each running the Bitbucket Server web application, behind a load balancer. This provides important benefits over Bitbucket Server:

  • Performance at scale: A cluster of many machines running Bitbucket Server can handle more load than a single machine.
  • High availability: If one cluster node goes down, then the remaining cluster node(s) can continue servicing requests so users should see little or no loss of availability. 
  • Smart mirroring: Smart Mirroring can improve Git clone speeds for distributed teams working with large repositories.
