The InfoQ eMag: Real-Time APIs: Design, Operation, and Observation


Application Programming Interfaces (APIs) are seemingly everywhere. Thanks to the popularity of web-based products, cloud-based X-as-a-service offerings, and IoT, it is becoming increasingly important for engineers to understand all aspects of APIs, from design, to building, to operation.

Research shows that there is an increasing demand for near real-time APIs, in which speed and flexibility of response are vitally important. This eMag explores this emerging trend in more detail.

The InfoQ eMag - Real-Time APIs: Design, Operation, and Observation include:

  • The Challenges of Building a Reliable Real-Time Event-Driven Ecosystem - Globally, there is an increasing appetite for data delivered in real-time; we are witnessing the emergence of the real-time API. When it comes to event-driven APIs engineers can choose between multiple different protocols. In addition to choosing a protocol, engineers also have to think about subscription models, too: server-initiated (push-based) or client-initiated (pull-based).
  • Real-Time APIs: Mike Amundsen on Designing for Speed and Observability - In a recent apidays webinar, Mike Amundsen, trainer and author of the recent O’Reilly book “API Traffic Management 101”, presented “High Performing APIs: Architecting for Speed at Scale”.  Drawing on recent research by IDC, he argued that organisations will have to drive systemic changes in order to meet the upcoming increased demand of consumption of business services via APIs.
  • Load Testing APIs and Websites with Gatling: It’s Never Too Late to Get Started - Conducting load tests against APIs and websites can both validate performance after a long stretch of development and get useful feedback from an app in order to increase its scaling capabilities and performance. Engineers should avoid creating “the cathedral” of load testing and end up with little time to improve performance overall. Write the simplest possible test and iterate from there.
  • Four Case Studies for Implementing Real-Time APIs - API calls now make up 83% of all web traffic. Competitive advantage is no longer won by simply having APIs; the key to gaining ground is based on the performance and the reliability of those APIs.  This article presents a series of four case studies of how real-time APIs were implemented.
  • Real-Time APIs in the Context of Apache Kafka - Events offer a Goldilocks-style approach in which real-time APIs can be used as the foundation for applications which is flexible yet performant; loosely-coupled yet efficient. Apache Kafka offers a scalable event streaming platform with which you can build applications around the powerful concept of events.
