AWS Lambda is a powerful cloud computing service that enables businesses to build and run serverless applications with ease. This service allows you to run code without the need for a dedicated server, which can significantly reduce costs while also increasing scalability and flexibility.
At its core, AWS Lambda allows developers to create functions in any of the supported programming languages, upload them to AWS, and then execute them in response to specific events. This could include actions such as file uploads, database updates, or even web requests. AWS Lambda will automatically scale your functions in response to demand, ensuring that your application remains responsive and available even during peak periods.
