AWS SDK for Java

The AWS SDK for Java v1 is the long-standing, feature-complete toolkit for calling AWS services from Java applications. It provides service clients for nearly the entire AWS surface area, handling request signing, retries, pagination, and error translation so you can focus on business logic. The SDK offers both synchronous and asynchronous clients and integrates with popular HTTP stacks, credential providers, and logging frameworks. Its data models map directly to service APIs, making it straightforward to construct requests and parse responses. Extensive configuration options let you tune connection pools, timeouts, retry policies, and regional behavior for production workloads. Although superseded by v2 for new projects, v1 remains widely used in mature systems due to its broad coverage and stability.
