AWS Tutorial AWS Solutions Architect and SysOps Administrator - What Is AWS Lambda?

This lecture introduces AWS Lambda, a service that allows running code in response to events without provisioning servers. It covers use cases like file processing, EBS snapshots, and data analytics. Lambda functions are executed via triggers such as API Gateway and Cloudwatch, with runtime tools provided for various languages. The service operates on a pay-as-you-go model, making it cost-effective for serverless architectures. The lecture also discusses the importance of IAM roles for accessing destination resources. The next lecture will demonstrate creating a Lambda function.
