This project is another comparison of infrastructure management tools for AWS. It demonstrates the use of Terraform modules and CDK constructs to produce multiple SQS queues with a consistent configuration.
There are four implementations:
- CloudFormation, as a baseline.
- CDK, showing the use of user-defined constructs.
- CDK-2, an extension that creates a combined queue policy.
- Terraform, which uses an in-project module to create the queue and related objects.
To run, you must have the ability to create SQS queues and IAM policies.I strongly recommend running in a "sandbox" account so that you won't interfere with operations.
Each variant lives in its own sub-directory, so that it can create artifacts without interfering with the others (this is particularly important for Terraform and CDK). The README for each variant describes how to run it.
Each variant of this project creates the following resources:
- Threee "primary" queues, named
Foo,Bar, andBaz. - Thread "dead letter" queues, named
Foo-DLQ,Bar-DLQ, andBaz-DLQ. - A consumer and producer policy for each queue (named
SQS-Foo-Consumer,SQS-Foo-Producer, and so on). - An "application role" that references the producer policies for all queues.
- (CDK-2 only) A consumer and producer policy for the queues as a group, named
SQS-STACKNAME-ConsumerandSQS-STACKNAME-Producer.
