What is AWS Lambda?
AWS Lambda is a part of compute service that helps you to run your code without provisioning or managing servers, which means you don’t need to manage servers on your own. Aws Lambda helps you to run your code on a highly available compute infrastructure and helps you to perform all the administration activities like operating system maintenance, automatic logging, and scaling. With the help of AWS Lambda, you can run your code virtually or run any type of application or any backend service for which you just need to supply your code in one of the languages AWS lambda supports.
Another advantage is that you can organize your complete code in Lambda functions. Lambda will run your function whenever required and helps scale automatically from a few requests per day to thousands per second.
Another best advantage of using AWS Lambda is you pay only for compute time that you use to compute. There is no charge when your code is not running.
Below are the ideas on when to use Lambda,
AWS Lambda is known for ideal compute service for many application scenarios, as long as you run your application code using AWS Lambda standard environment. Also, you can use AWS Lambda for file processing, stream processing, web applications, IOT backends, and Mobile backends.
File Processing
You can use Amazon S3 (Amazon Simple Storage Service) to trigger lambda data processing in real-time after uploading a file or document.
Stream Processing
Using AWS Lambda, you can process real-time streaming data for any of your application activity trackings, click stream analysis, transaction order processing, data cleansing, indexing, log filtering, social media analysis, and Internet of Things (IoT) device data telemetry.
Web Application
You can combine your AWS Lambda with any other AWS service to build powerful web applications that automatically scale up and down and run in highly available configurations across multiple data centers.
IoT backends
You can build serverless backends using Lambda to handle web, mobile, and other third-party requests.
Mobile Backends
You can easily build backends using Lambda and Amazon API Gateway to authenticate and process all your API Requests.
So, to create a lambda function, you need an AWS account to create a lambda function. In the next article, I will guide you to create a lambda function in the AWS console.
