Setup
To create a Datomic Cloud system:
These tasks need only be performed once, by an AWS administrator.
If you want to try Datomic locally without incurring AWS expense, you can install dev-local first.
Naming Systems and Applications
System and application names cannot be changed, so choose good names. Points to consider:
- Choose a name of up to 23 lowercase ASCII characters, numbers, and/or hyphens.
- 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".
Create a Storage Stack
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
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.
Create a Compute Stack
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
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.
