Every web developer wants to build a website that adheres to the almost mythical “best practices” so that it is light and performant. But how exactly are developers supposed to measure performance? And what is considered to be a best practice when it comes to developing for the web?

While creating a Docker image, one of the most important decisions to make is what base image to use. In this post I’ll compare three kinds of base images for you.

Cost-efficiency is one of the main pillars of the Serverless Well-Architected framework. Read-intensive applications can save money and improve efficiency by using cache systems. AWS Lambda’s internal memory could be used as a caching mechanism. A Lambda container remains alive after an invocation is served, even if it stays idle for some time. Whatever was loaded in the container’s memory will remain there for the next invocations.

The most common integration type for AWS API Gateway is with Lambda functions. The API service can integrate with virtually any other service that accepts HTTP requests, though. This opens up possibilities to use the API Gateway as a proxy to database queries, without any compute layer such as a Lambda function. The direct integration between API and database is perfect when Lambda serves only as an intermediator.

Everyone knows the existential question: If a tree falls in the forest, and nobody is there to hear it, does it make a sound? Leading-edge customer service management today has produced a corollary: If a network problem is fixed before the customer even suspects there’s an issue, did it even happen?
