What is Amazon Web Services (AWS) Lambda?

Amazon Web Services (AWS) Lambda is a serverless computing service designed to let you run programs without having to run your own servers or do any code administration. By uploading your code as an image or ZIP file, AWS Lambda will automatically dedicate the amount of computational power necessary to run the code request. You can trigger the code to run automatically over hundreds of AWS and Software-as-a-Service (SaaS) applications, or control its execution directly from an online app. Lambda applications can scale to meet a program's associated traffic and can be written in numerous programming languages.
