AWS Lambda Function Complete Guide

What is the AWS Lambda function?

AWS lambda is a computing service that runs your back-end code in response to events and automatically manages the computing resources required by that code. AWS lambda is Serverless because you don’t need to manage the infrastructure and servers, which are automatically scalable and controlled by AWS. The AWS lambda function allows us to add our custom logic to the services provided by AWS such as Amazon s3 buckets and Amazon DynamoDB tables.

Let’s consider that you are building an application and want it to deliver a great experience to the users. Maybe you want your application to generate in-app purchase options during a gaming session or make image thumbnails available instantly after a user uploads photos. To make this magic happen your application needs back-end code that runs in response to events like image uploads in app activity website clicks or sensor outputs. Also you need to manage the infrastructures and servers to keep it available when events are being triggered or requests are generated, which is a huge headache.

Here comes the AWS lambda which is a serverless computing service. The developer just has to write his custom logic inside the lambda function, which will be triggered when a specific event happens or a request is generated. Once the code has been uploaded to the lambda function, all the capacity, scaling, patching and administration of the infrastructure to run your code is taken care of by AWS. Lambda provides visibility into performance by publishing real-time metrics and logs to Amazon Cloud. when you use AWS lambda you’re simply charged a low fee per request and for the time your code runs measured in increments of 100 milliseconds.

You can use any of these languages of your own choice to create any application without provisioning any server.

AWS Lambda provides a Runtime API which allows you to use any additional programming languages to author your functions.
