Start a System

To start a Datomic system:

• setup your AWS account
• choose a system name
• create a storage stack
• create a compute stack

System and application names cannot be changed, so choose good names. Points to consider:

• Datomic creates AWS resources named "datomic-[system]-[subresource]", so you should keep your system name short – and don't name your system "datomic".
• Multiple systems might serve the same primary database in different development stages. So you might name systems via the convention "[db]-[stage]", e.g."inventory-dev", "inventory-staging" and "inventory-prod".
• A system can serve more than one application via different query groups, although one application is often primary. So you might name applications "[db](-[app])", e.g. "inventory" and "inventory-analytics".

To create a storage stack from the CloudFormation console

• Click "Create Stack"
• Click "With new resources (standard)"
• Choose "Amazon S3 URL" as a template source.
• Set the Amazon S3 URL to the latest

Storage Template 995-9204

You will need to choose a stack name, but you can generally leave all stack parameters set to their default values. The storage template reference has details.

To create a compute stack from the CloudFormation console

• Click "Create Stack"
• Click "With new resources (standard)"
• Choose "Amazon S3 URL" as a template source.
• Set the Amazon S3 URL to the latest Primary Compute Template 995-9204

Unlike the storage stack, the compute stack has a number of parameters that you should review and adjust to match your specific needs. See the compute template reference for details.
