Intro to AWS Lambda

What’s AWS Lambda & How AWS Lambda works:

Off the bat we want to introduce what AWS Lambda is, and how AWS Lambda works. Launched in 2014, its an event-driven, server-less computing technology available through Amazon Web Services (AWS). As a result, you won't have to worry about deciding which AWS resources to launch or how to maintain them. Instead, you must upload the code to Lambda, where it will execute. Codes run within (VPC) Virtual Private Cloud by default in AWS Lambda, its performed in reaction to events in AWS services such as adding/deleting files in an S3 bucket, making an HTTP call to the Amazon API gateway, and so on.?

Instead of managing operating system (OS) access control, OS patching, right-sizing, provisioning, scaling, and other tasks, the AWS Lambda function allows you to focus on your core product and business logic.?

Core concepts? include the following:

  • Functions – Program that processes events passed by Lambda?
  • Runtimes — Allows functions in languages, matches your language and configures functions as well
  • Event Source — A service that helps in the execution of logic
  • Lambda Layers — Manages development functions and important distributions of things like libraries and such
  • Log Streams — Sequence of log events from the same source

Who uses AWS Lambda? & Where is AWS Lambda Used?

With large scaled customers like Netflix, Nike, Audible Inc, and JP Morgan Chase, AWS Lambda has become one of the most popular and used cloud strategies. It is a favorite as it minimizes maintenance. According to Tech Magic there are fourteen outstanding use cases for AWS Lambda. These include, building serverless website, authentication, mass emailing, real-time notifications, chatbots, media transformation, real-time data processing, custom workflows, change data capture, Alexa, image recognition engine, text-to-speech, efficient monitoring, and personalized content.

Is AWS Lambda free?

There is a free tier available and users get one million requests per month and 400,000 GB-seconds per month for free as well. Otherwise there are costs that you pay according to the compute you use. The pricing page of AWS has more specific breakdowns with its pricing calculators.?
