We want to run Bitbucket server on AWS for High Availability to achieve deployment in Multi Availability zones. We are looking to use AWS EFS service as it is Highly available file system service on AWS. But, when looking through Atlassian documentation, the only thing we noticed regarding EFS is "You can't use Amazon Elastic File System (EFS) for Bitbucket server's shared home directory.
What is Atlassian's recommendation to run Bitbucket on AWS with Multi region & Multi AZ environment to achieve HIgh Availability & Fault Tolerance?
Welcome to the Community!!
Have the NFS Server installed on VM with attached Disk, which then replicates the data to EFS if you need.
But you have to manage the NFS Server and all its resources monitoring via AWS Monitoring.
Let me know if you need any further inputs
Thanks for your response on our query.
In such case to to run Bitbucket on AWS with Multi region & Multi AZ environment :
Could you please clarify on the below things:
1. Do we need to install NFS server in each Availability Zone (AZ)?
2. If need to install NFS in one AZ and EFS for replication in other AZ, then read & write operations will be done in NFS? or EFS also ?
3. If possible, can you share us a sample documentation & a simple diagram which can explain more in detail about this architecture . Also, Please note that the existing Bitbucket Data Center migration page has single AZ deployment
4. As we need to implement a multi-region & multi-AZ Bitbucket data center deployment to achieve High Availability & fault tolerance. Please guide/suggest on this requirement standards
It depends on NFS Server Architecture if it's standalone, there's no need for AZ otherwise you can go with multiple AZ with at least two nodes.
Only NFS will be read and written, EFS will be used as backup here
Here's the Reference for NFS Installation
