Application Programming Interface
A defined set of rules and protocols that allows different software systems to communicate with each other.
Detailed Explanation
APIs serve as the contracts between microservices, external platforms, and frontend applications. They abstract the internal logic and expose only the necessary endpoints for interaction.
Why It Matters
They enable modular architecture and integrations, allowing independent teams to build complex systems without needing to understand each other's codebases.
Common Failure Mode
Practical Example
Production Manifestation
RESTful endpoints, GraphQL schemas, or gRPC services facilitating data exchange across the network.
Frequently Asked Questions
What is Application Programming Interface in short?
A defined set of rules and protocols that allows different software systems to communicate with each other.
What is the most common failure mode?
Making backwards-incompatible changes without versioning, which instantly breaks downstream consumers during deployment.
