AWS Lambda is a serverless compute service that lets you run code in response to events and automatically manages the underlying compute resources. It is a popular choice for building event-driven architectures and can be used for a wide range of use cases such as data processing, image and video processing, and real-time stream processing.
Use it when :
- - You want to builder event-driven applications that respond to changes in data or user actions.
- - You want to run code without managing servers or infrastructure.
- - You want to scale your application automatically and only pay for the compute time you consume.
- - You want to integrate your application with other AWS services such as Amazon S3, DynamoDB, and API Gateway.
- - You want to builder microservices and APIs that can be easily deployed and managed.
- - May require additional development effort to architect serverless applications.
- - May have some limitations on the amount of compute resources available per function.
- - May have a longer cold start time for functions that haven't been recently used.
- - May require careful management of permissions and roles to ensure data security.
- - May be more expensive compared to running servers for long periods of time.
