Building a serverless application changes the way developers think about testing their code. Previously, developers would emulate the complete infrastructure locally and only commit code ready for testing. However, with serverless, local emulation can be more complex. In this post, I show you how to bypass most local emulation by testing serverless applications in the […]

There are multiple factors to consider when tuning a federated GQL system. You must be aware of trade-offs when deciding on factors like the runtime environment of Lambda functions. An extensive testing strategy can help you scale systems and narrow down issues quickly. Well-defined testing can also keep pipelines clean of false-positive blockages.

This blog post shows how to create a scalable difference checking tool for objects stored in S3 buckets. The Lambda function is invoked when S3 writes new versions of an object to the bucket. This example also shows how to remove earlier versions of object and define a set number of versions to retain.

In 2010, AWS released launch configurations as a way to define the parameters of instances launched by EC2 Auto Scaling groups. In 2017, AWS released launch templates, the successor of launch configurations, as a way to streamline […]

This post describes guardrails that you can set up in your accounts or across the organization to keep control over deployed resources. These guardrails can be more or less restrictive according to your requirements.

This blog shows an event driven approach to handling dynamic SNS subscription requirements. It relies on the ECS service events to trigger appropriate Lambda functions. These create the subscription queue, subscribe it to a topic, and delete it once the container instance is terminated.

This post written by Dhiraj Mahapatro, Senior Specialist SA, Serverless. AWS Step Functions is a low-code visual workflow service used to orchestrate AWS services, automate business processes, and build serverless applications. Step Functions workflows manage failures, retries, parallelization, service integrations, and observability so builders can focus on business logic. AWS Batch is one of the […]

APIs act as the front door to applications and allow […]

This post shows a number of solutions to create and share archetypes or layers across the company. With these archetypes, development teams can quickly bootstrap projects with company standards and best practices.

It’s best practice to store the output of the Lambda function in a different bucket or AWS resource than the source bucket. In cases where you need to store the processed object in the same bucket, I show three different designs to help minimize the risk of recursive invocations.
