Lambda has become popular thanks to AWS. in this blog, we are going to shed some light on AWS Lambda, including how it binds into serverless architecture, how to create it, and when to use it.
To understand what AWS Lambda is, we must have knowledge of what serverless architecture is all about.
Serverless applications do not require any managing servers for them to run. When you run a serverless application, you don’t need to worry about OS setup, patching, and scaling of servers that you would have to worry about while running an application on a physical server.
The traits of serverless applications
Various components of serverless applications
AWS offers services that can be used for each of these components that make up a serverless architecture. This is where AWS Lambda comes in.
Narrating AWS – Lambda
As defined by the AWS official source, “AWS Lambda is a compute service that lets you run code without provisioning or managing servers. It executes your code only when needed and scales automatically, from a few requests per day to thousands per second.”
Lambda speeds up the execution process and scales your application or code, by executing the events triggering a particular code.
When configuring a lambda function, you specify which runtime environment you’d like to run your code in. All environments are based on Amazon Linux AMI.
The current available runtime environments are:
