AWS Lambda

Lambda is the flagship product of the serverless concept. The ability to run functions on demand with zero administration and its particular pricing model is the main drive that aroused interest in the developer community. We can say that we have serverless databases, serverless notifications, and serverless frontends, but those are merely extensions of the main feature, that is, serverless code executions.

Lambda currently only supports Node.js (JavaScript), Python, Java, and C# languages, but there is a third-party framework named Apex (https://github.com/apex/apex) that adds support for Go, Rust, and Clojure by injecting Node.js shims in the deployment build.
