Traditional containerized applications face significant hurdles with scalability, operational complexity, and security management.
Serverless computing offers improved scalability, reduced operational overhead, cost-effectiveness, and built-in high availability.
The AWS Cloud Development Kit (CDK) allows you to define cloud infrastructure using familiar programming languages, which then synthesizes into CloudFormation templates.
A CDK application is organized as a tree of constructs, with stacks serving as the primary deployment units for grouping related resources.
Test Lambda function logic with standard unit tests and verify CDK-generated templates using fine-grained assertions and snapshot testing.
Validate the interaction between a Lambda function and DynamoDB by running integration tests against a local DynamoDB instance.
Use the CDK integration test runner to deploy, test, and destroy resources in the cloud for services that lack a local equivalent, like EventBridge Pipes.
A reliable serverless application requires a multi-layered testing approach, including local unit tests, template assertions, and cloud-based integration tests.
Answering audience questions about the costs of spying on SDK calls and the process for setting up a local DynamoDB instance for testing.
