Deploy JIRA app server on AWS and DB in local datacenter

[Bojan Kalicanin]

Is it possible to deploy JIRA application server on AWS and use Database server deployed in our local datacenter? Is this set-up possible and will it run ok, regarding network throughput and latency?

It might be technically possible, but I certainly would not recommend this setup.   As long as the application server can reach the network address of the SQL server, it should work in theory.

But in practice, I think you will find that the added network latency will cause you severe performance problems for Jira to start with.  In addition to that, I would suspect that your SQL traffic might want to also use SSL/TLS in order to encrypt the database traffic.  This just adds additional overhead to the network traffic that is already likely to suffer much higher network latency because of network routes.

You could try this if you want of course.   It might help to see just how bad the latency is by following the KB: Testing database access speed.   This is a java jar file you can use to test out how well a Java application, like Jira, could access whatever database address you enter.

In regards to using AWS, we're even concerned to see data center nodes using different AWS regions for the same potential latency problems.   If the latency between regions is very low, it typically is not a problem, but It's just not usually worth the potential problems here.  When using a database in the same private network (such as in an AWS setup with Jira data center), you don't need to use encryption for the network traffic between your Jira application and that database, so there is also let overhead in this setup.

Thank you on such thorough explanation, I was suspecting that latency could be a big problem, but needed to check if I am thinking in right direction.
