Title

AWS re:Invent 2023 - Simplify building applications with AWS SDKs (DOP220)

Summary

AWS SDKs cover over 350 services and support 12 programming languages with daily updates.
Key SDK features include authentication, profile files, automatic retries, waiters, paginators, endpoint resolution, and more.
AWS uses model-driven API development to scale SDKs, using Smithy, an open-source interface definition language.
Smithy allows for consistent API design, code generation across languages, and ensures backward compatibility.
SDKs provide additional features like asynchronous operations, paginators, event streams, and smart defaults.
The Smithy reference architecture is introduced for modularity, observability, and extensibility in SDKs.
New SDKs support the Smithy reference architecture, and existing SDKs are being updated to include it.
The architecture allows for customization and integration with observability backends.
The session emphasizes spending less time on SDKs and more on business logic.

Model-driven API development with Smithy is central to AWS's strategy for managing the complexity of supporting numerous services and languages.
Smithy's open-source nature allows customers to adopt similar practices for their own API development.
The Smithy reference architecture aims to standardize SDK behavior across languages, making it easier for developers to work with AWS services.
The architecture's modularity means that only necessary components are included, reducing overhead and improving performance.
Customizability through interceptors and integration points allows developers to tailor SDK behavior to their specific needs.
AWS is committed to improving developer experience by reducing boilerplate code and focusing on features that simplify interactions with AWS services.
The session highlights the importance of backward compatibility and customer experience in API development.
AWS's approach to SDK development reflects a broader trend in software development towards automation, standardization, and developer efficiency.
