Azure VM sizes

[Kfir Goldwasser]

hello

I am starting to work with Atlassian tools in my DevOps and whould like to know that is the recommended size for the VM need to creat in Azure for:

Confluence, JIRA, Bit Bucket

(will have 2 environment - prod, none prod).

what is the optimize number of VM for such implementation?

(for example: can all none prod tools be on the same server?)

if and what kind of DB will I need 

thanks

Atlassian provides some specific guidance for choosing Azure node when you run Data Center. If you are just running Server instances, then the Jira sizing guide is your best bet.

From my experience, it's best to run each application in a dedicated VM. As @Thomas Deiler and @Corentin Méhat point out, this simplifies troubleshooting and reduces downtime when upgrading. It also prevents swamping compute resources under peak loads. Especially when the products are integrated, it is common for Bitbucket, Confluence, and Jira to all want RAM and CPU at the same time, when teams are at their busiest. This option also allows you to better tune performance, by bumping up the VM size per application.

Hello,

• for JIRA, Atlassian didn't changed their recommendations since a few versions, so you can start with this page : https://confluence.atlassian.com/enterprise/jira-sizing-guide-461504623.html
• roughly the sames can be applied to Confluence for a start.
• My recommendation would be to have the same sizing on prod and test to actually have a replica and reproduce the same perf issues if you have some.
• You should install each application on a different VM, will ease the installation and reduce the potential problems.

Just FYI, the recommendations page linked above is for Jira 6.3. Here's the updated version for Jira Data Center 7.x: Jira Data Center size profiles.

hi Thomas

thank for the reply. my question then, what size would you start with?(is there a best practice)? I believe I will start with around 100 users to start with.

Dear @Kfir Goldwasser,

I recommend to have for a staging environment same configuration as for prod. So you can quickly figure out, of an upgrade/other modification is working as expected and apply the changes to prod.

If you have enough resources on the VM host system, create for each application an one instance. Reduces risk and downtime greatly when updating.

So long

Thomas
