Amazon Lambda

Amazon Lambda is a cloud service that runs your code in response to specific events without needing to manage servers. You upload your code, define triggers (like file uploads or button clicks), and Lambda automatically executes the code when those triggers occur. It scales automatically, handling many requests simultaneously, and you only pay for the compute time your code uses. Essentially, Lambda enables you to build applications that respond dynamically to events while abstracting away server management, making your workload more efficient and cost-effective.
