Trying to install JIRA on an EC2 micro instance, that has only 600MB. The moment I start tomcat, JIRA uses up almost all existing memory, it is very very slow and it doesn't even start completely.

Anyone has experience with installing JIRA on EC2? Do we need more than 1GB memory? I emailed JIRA tech support, they replied saying they don't have any experience/knowledge installing JIRA on Amazon, so that wasn't much help

This question came from our site for computer enthusiasts and power users.

Just curious - what EC2 instance type did you settle for, and how well does it work? – Prembo Apr 9 '12 at 4:31
JIRA can be started on an EC2 micro instance… But you have to be patient when working in this environment. It will take several seconds until new page is rendered. – Sergey Balashevich Sep 14 '12 at 11:08

Atlassian have some information on the system requirements you can expect based on the issue count on your server:

The article suggests that 1-2 GB should be the minimum for a small installation:

If you are planning to have a small number of projects (10-20) with 1,000 to 5,000 issues in total and about 100-200 users, a recent server (2.0+ GHz quad core CPU) with 1-2 GB of available RAM should cater for your needs.

However they also state that their massive public Jira instance only requires 1.5 GB of RAM for Jira itself:

For reference, our site has over 70,000 issues and over 30,000 user accounts. The system runs on a server with a 64-bit quad core processor and 32 GB of memory, of which only 1.5 GB is allocated to JIRA.

That would not take into account the other services running on the machine (e.g. a local database, OS needs)

Personally I run Jira with a local MySQL server on the same EC2 instance, but I use a 'small' instance. It does not fall within the free tier, but as I only turn it on as I need it, the cost is only a few dollars a month.
