Today's Datomic Cloud release provides an easy way to parameterize ion applications.
Rationale
At runtime, applications need access to configuration data such as the name of a Datomic database. There are several challenges to consider:
- Configuration values have a lifecycle that is independent of application source code. They should not be hard-coded in the application, and should be managed separately from source code.
- Applications need a way to obtain their configuration values at runtime.
- Configuration values may be sensitive, and should not be stored or conveyed as plaintext.
Parameters are a solution to these challenges.
Ion Parameters
Before running your app, you store parameter values under hierarchical keys in
AWS Systems Manager Parameter Store. At runtime, your app uses our new APIs to form the keys and read the values. This provides:
- independent lifecycle for parameter values
- encryption for sensitive data
- granular IAM permissions
