Final answer:
Commonly used services within serverless architectures include API Gateway for routing client requests, Lambda for event-driven computation, Kinesis for real-time data streaming, Step Functions for orchestrating workflows, and S3 for scalable object storage. Services like EBS and ECS are not typically part of serverless architectures as they involve server management.
Step-by-step explanation:
Within serverless architectures, there are several commonly used services that help manage different aspects of application deployment and runtime without the need to manage servers. Here are some of the key services:
- API Gateway: Serves as the entry point for client requests and routes those requests to the appropriate backend services like Lambda functions. It can handle user authentication, rate limiting, and API version management.
- Lambda: A compute service that runs your backend code in response to events, such as HTTP requests via API Gateway, or modifications to data in Amazon S3. You pay only for the compute time you consume, and there is no charge when your code isn't running.
- Kinesis: Facilitates real-time data processing over large, distributed data streams, which is useful for gathering, processing, and analyzing streaming data.
- Step Functions: Allows you to orchestrate multiple AWS services into serverless workflows so that you can build and update apps quickly.
- S3 (Simple Storage Service): Provides scalable object storage for data backup, archival, and analytics. A foundational service for serverless applications that require storage without managing infrastructure.
Services like EBS (Elastic Block Store) and ECS (Elastic Container Service) are not considered serverless since they require server provisioning and management. Serverless architectures enable developers to build and run applications and services without thinking about servers and are designed to scale automatically with usage.
