Managing External APIs in Enterprise Systems

Explore effective strategies for managing external APIs in enterprise systems through this comprehensive conference talk from ACCU 2023. Learn how to properly encapsulate external APIs to protect your system and implement modern idioms. Discover techniques for handling changing requirements, including decommissioning old functionality in real-world scenarios. Understand how abstractions can act as powerful absorbers of change, limiting the impact on production codebases. Follow along as the speaker demonstrates these concepts using a real-world application, showcasing sound engineering choices to create more efficient modern interfaces. Gain insights into preserving global calling semantics, introducing localized decoupling, and applying engineering techniques to unit and system testing code. Explore additional real-world challenges such as batching and parallelization while maintaining localized code changes during migration. Benefit from the speaker's extensive experience in successfully implementing these approaches in Bloomberg and other large-scale engineering projects.
