AWS Lambda AWS Lambda is one of the computing services provided by AWS, which is event-driven and serverless. It is a stateless serverless system that helps us run our background tasks in the most efficient manner possible. Benefits of AWS Lambda AWS Lambda provides us the following benefits: Due to its serverless architecture, no need to provision or manage servers No need to set up any virtual machine (VM) Lambda tasks need not to be registered like Amazon SWF activity types. We can use any existing Lambda functions that you’ve already defined in workflows. Lambda functions are called directly by Amazon SWF; there is no need design a program to implement and execute them. Lambda provides us the metrics and logs for tracking function executions. Allows developers to run and execute codes in response to events without the need for building any infrastructure Pay as you go : Just pay for the compute time taken, only when the code runs. Also, pay only for the used

Cloud Computing Before proceeding with AWS Lambda, let’s first understand its domain, Cloud Computing, where AWS has originated from. Cloud Computing is simply a practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than using a local server or a personal computer. But, why are we talking about AWS when there are numerous other Cloud Computing vendors? Here are some of the major players in the marketplace when it comes to Cloud Computing. If we talk of services, AWS Compute plays a major role while we work with AWS as it provides us secure and resizable computing capacity on the cloud. What is AWS Lambda? AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code. The Lambda functions can perform any kind of computing task,
