Serverless COBOL: Rejuvenating legacy code with open source software — Part 1

In this post, we explain how using open source software, GnuCOBOL, combined with AWS Lambda functions, can extend the life of legacy code into a serverless context. We also examine additional benefits of open source software when legacy features are deployed in such a modern environment. The COBOL code described in this post—CI/CD scripts—are available […]

Testing AWS Lambda functions written in Java

Testing is an essential task when building software. Testing helps improve software quality by finding bugs before they reach production. The sooner we know there is a defect in code, the easier and cheaper it is to correct. Automated tests are a central piece in reducing this feedback loop. In association with a continuous integration […]

Simplifying serverless best practices with Lambda Powertools

Modern applications are increasingly relying on compute platforms based on containers and serverless technologies to provide scalability, cost efficiency, and agility. Although this shift toward more distributed architectures has unlocked many benefits, it has also introduced new complexity in how the applications are operated. In times past, debugging was as straightforward as logging into the […]

Deploying an AWS Lambda function with the serverless framework and Tekton

This article is a guest post from Sebastien Goasguen, co-founder of TriggerMesh. Deploying AWS Lambda functions with the serverless framework is arguably the easiest way to deploy functions and configure how they get triggered. If you want to automate your function deployment, you will most likely do so via your CI/CD workflow. A CI/CD pipeline […]
