1. Using Amazon Web Services

Amazon provides a Java SDK to issue requests for the all services provided by the Amazon Web Service platform. Using the SDK, application developers still have to integrate the SDK into their application with a considerable amount of infrastructure related code. Spring Cloud AWS provides application developers already integrated Spring-based modules to consume services and avoid infrastructure related code as much as possible. The Spring Cloud AWS module provides a module set so that application developers can arrange the dependencies based on their needs for the particular services. The graphic below provides a general overview of all Spring Cloud AWS modules along with the service support for the respective Spring Cloud AWS services.spring-doc.cn

Overview

  • Spring Cloud AWS Core is the core module of Spring Cloud AWS providing basic services for security and configuration setup. Developers will not use this module directly but rather through other modules. The core module provides support for cloud based environment configurations providing direct access to the instance based EC2 metadata and the overall application stack specific CloudFormation metadata.spring-doc.cn

  • Spring Cloud AWS Context delivers access to the Simple Storage Service via the Spring resource loader abstraction. Moreover developers can send e-mails using the Simple E-Mail Service and the Spring mail abstraction. Further the developers can introduce declarative caching using the Spring caching support and the ElastiCache caching service.spring-doc.cn

  • Spring Cloud AWS JDBC provides automatic datasource lookup and configuration for the Relational Database Service which can be used with JDBC or any other support data access technology by Spring.spring-doc.cn

  • Spring Cloud AWS Messaging enables developers to receive and send messages with the Simple Queueing Service for point-to-point communication. Publish-subscribe messaging is supported with the integration of the Simple Notification Service.spring-doc.cn

  • Spring Cloud AWS Parameter Store Configuration enables Spring Cloud applications to use the AWS Parameter Store as a Bootstrap Property Source, comparable to the support provided for the Spring Cloud Config Server or Consul’s key-value store.spring-doc.cn

  • Spring Cloud AWS Secrets Manager Configuration enables Spring Cloud applications to use the AWS Secrets Manager as a Bootstrap Property Source, comparable to the support provided for the Spring Cloud Config Server or Consul’s key-value store.spring-doc.cn
