Amazon's integration of Simple Queue Service (SQS) as a supported event source for AWS Lambda enhances serverless computing by allowing Lambdas to be triggered directly by messages in SQS queues. This development streamlines the process, eliminating the need for dedicated services to poll SQS or create SNS notifications. Pulumi, a cloud infrastructure as code platform, quickly adapted to this functionality, enabling users to define infrastructure components like AWS Queues and Lambdas directly in code. By leveraging this new API, users can efficiently set up event subscriptions that trigger Lambdas upon receiving SQS messages, demonstrated in an example where SQS messages are posted to Slack. Pulumi's integration with Terraform initially encountered a challenge due to a constraint in an older API, but a collaborative effort resolved the issue, allowing both Terraform and Pulumi users to benefit. The update simplifies creating serverless applications, enabling rapid provisioning of AWS resources and demonstrating an end-to-end message-receiving and processing pipeline in just a few lines of code, with improvements to be included in upcoming Pulumi releases.
