Open source builders: Lessons learned

Part 1—Open source builders: Getting started Part 2—Open source builders: Lessons learned This two-part article series is based on recent interviews with Alex Casalboni, Senior Technical Advocate at AWS, about his project AWS Lambda Power Tuning; Olaf Conijn, Principal Architect at Moneyou, about his project that is helping users more effectively build infrastructure; and Liz […]

Open source builders: Getting started

Part 1—Open source builders: Getting started Part 2—Open source builders: Lessons learned Inspired by Matt Asay’s recent Open Source Builders series on The New Stack, I sat down and talked with three open source developers, project maintainers, and community contributors. I wanted to know why they joined or created their first open source projects, what […]

Amazon Chime SDK: Deploying live events solution screenshot

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 […]

Realize policy as code with AWS Cloud Development Kit through Open Policy Agent

AWS Cloud Development Kit (AWS CDK) is an open source software framework that allows users to define and provision AWS infrastructure using familiar programming languages. Using CDK, you can version control infrastructure, and the Infrastructure-as-Code concept opens up new opportunities to manage AWS infrastructure more efficiently and reliably. But when planning to deploy new AWS […]

Deploy machine learning models to Amazon SageMaker using the ezsmdeploy Python package and a few lines of code

Customers on AWS deploy trained machine learning (ML) and deep learning (DL) models in production using Amazon SageMaker, and using other services such as AWS Lambda, AWS Fargate, AWS Elastic Beanstalk, and Amazon Elastic Compute Cloud (Amazon EC2) to name a few.

Generate Python, Java, and .NET software libraries from a TypeScript source

As builders and developers, many of us are aware of the principle of Don’t Repeat Yourself (or DRY) and practice it every day. Entire runtimes and programming languages have been developed by taking that principle to an even higher level, with the core idea of writing software once and having it run on many different […]
