What is Amazon Lambda?

Amazon Lambda is a serverless computing tool provided by Amazon Web Services (AWS). It allows developers to run their code and execute functions in response to events without worrying about managing servers or infrastructure.

At its core, Lambda performs two key functions: event-driven compute service and function-as-a-service (FaaS) platform. Event-driven compute service refers to the ability of Lambda to automatically trigger code execution in response to events, such as changes in data or the occurrence of specific conditions. This eliminates the need for developers to constantly monitor and manually execute their code.

As a FaaS platform, Lambda enables developers to write their code in small, self-contained functions called "Lambda functions." These functions can be written in various programming languages like Python, JavaScript, and Java. Each function performs a specific task, such as processing data, generating reports, or managing workflows.

When an event occurs, Lambda launches the corresponding Lambda function, allocates the necessary computing resources, and executes the code. The service automatically scales resources based on the incoming workload, ensuring optimal performance and cost-efficiency. This aspect of Lambda makes it particularly well-suited for applications with unpredictable or fluctuating workloads.

Lambda also integrates seamlessly with other AWS services, allowing developers to utilize the full suite of AWS resources and capabilities. It can be easily combined with services like Amazon S3 for storage, Amazon DynamoDB for databases, or Amazon API Gateway for building APIs.
