Proper SOA isolation: The 3 frontiers
Posted on January 9, 2023, Level intermediate Resource Length medium
Building service is easy. Isolating that service, it's easier said than done. Anyone can build any service with any technology or stack. However, would this service last, or will it become technical debt? Many organizations trying to go all in with microservices end up with distributed monoliths instead of isolated services. By Diego Pacheco.

Securing Lambda function URLs using Amazon Cognito, Amazon CloudFront and AWS WAF
Posted on December 31, 2022, Level intermediate Resource Length medium
Lambda function URLs is a dedicated HTTPs endpoint for a AWS Lambda function. You can configure a function URL to have two methods of authentication: IAM and NONE. IAM authentication means that you are restricting access to the function URL (and in-turn access to invoke the Lambda function) to certain AWS principals (such as roles or users). Authentication type of NONE means that the Lambda function URL has no authentication and is open for anyone to invoke the function. By Marcia Villalba.

WebSockets in a serverless world
Posted on November 18, 2022, Level intermediate Resource Length medium
Serverless and WebSockets is a bit of a contradiction. Serverless implies that we're not managing servers ourselves, they've been abstracted away for our convenience. WebSockets allow us to communicate between a "client" and a "server", but what happens when that server is "serverless"?! By Jo Franchetti.

The future is serverless
Posted on November 6, 2022, Level beginner Resource Length medium
Why serverless computing is the future of all cloud computing. Since the introduction of cloud computing, the field experienced a series of back-and-forth evolutions, partly driven by cost factors that repeated themselves in various guises. However, in recent years, a new motivating factor might help cement the next evolution of cloud computing. By Michael Maximilien, David Hadas, Angelo Danducci II, Simon Moser.
