Press the services dropdown and select Lambda Moving on, fire up a browser and navigate to your account. If you don’t have an account, don’t hesitate to create one, they have incredible free tiers that include various services and last up to 12 months. Creating your first Node.js AWS Lambda functionīefore you can even see the code, you need to create a new function in the AWS console.
Hence making every subsequent request faster because AWS is skipping the initial creation of the VM if it already exists. The code is deployed into the Lambda service and then executed. I just used the example so you would understand it a bit easier. Instead, Lambda uses Firecracker, a lightweight open-source VM implemented in Rust. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely, and confidently for Linux, Windows Server, and Linux-on-mainframe appsĮvery time a Lambda Function is created, a container is spun up to serve it. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. But how? Containers!ĭocker is the world’s leading software container platform. You deploy the code into the cloud, and it handles the creation of all required resources by itself. What’s going on is that you, the developer, don’t need to worry about the infrastructure your code is running on. Well, the code is not running on potatoes, is it!? Okay, that’s just a saying. It’s groundbreaking because of the lack of servers. The architecture AWS Lambda belongs to is called either serverless computing or Function as a Service. I’ll only take a few minutes out of your already busy day, and you surely won’t mind.
Little did I know what AWS Lambda was and how incredibly awesome it is. That struck a chord, remembering the good old days of playing Half-Life as a kid. Once upon a time, not so long ago, a word caught my ear. In this hands-on walkthrough, we’ll show you how to get started and create your first Node.js AWS Lambda function. AWS Lambda is an incredible tool that works well with an abundance of other services on AWS.
