API Design Principles for Scalable Systems Building APIs that scale means planning for growth in traffic, data, and teams. A strong contract helps every service stay in line, even as features change. Clear design reduces surprises and speeds integration for clients and internal teams alike. Keep a clear contract Define stable interfaces with explicit inputs, outputs, and error shapes. Use consistent naming, data formats, and status codes. Document expectations and edge cases so teams can rely on the contract. Versioning and compatibility ...

APIs and Middleware Designing Connected Systems Connected systems rely on clear APIs and reliable middleware. A good design begins with a stable contract: list the resources, the required inputs, and the expected responses. It should also define how errors look and how clients can recover from failures. This clarity helps teams ship features faster and keeps services decoupled. Middleware is the connective tissue between services. An API gateway can handle authentication, rate limiting, and routing. A message broker enables asynchronous work and resilience. An orchestration layer helps coordinate long-running processes. Data transformation lets teams speak a common language, even when services use different data models. ...
