3. Info-Tech Research Group3 3 Resolution Situation ! Complication ? Info-Tech Insight Executive summary Organizations are looking for ways to leverage web APIs in order to increase app quality, code reusability, and improved development throughput. Organizations are looking for opportunities to create an application ecosystem which can expose internal services across the organization and/or external business partners. Web APIs are regularly designed for short-term code reuse. When they eventually break, the redevelopment effort is significant. Web APIs are commonly tested using functional testing through an application’s user interface. This ignores other testing techniques that are available, resulting in missed test cases. Define the business purpose of the web API and the common uses cases that it will service. Understand the development techniques are required to develop an effective web API based on Info-Tech’s web API development framework. Continually improve your web API development approach to demonstrate to business stakeholders the value your web API provides. Make web API development a strategic competency that is critical to enabling speed of development, quality of applications, reusability, innovation, and business alignment. Design your web API as a product to be consumed which will promote speed of development and service reuse. Incrementally optimize the design, development, testing, and monitoring of your APIs to cover all use cases in the long term.

Realize the importance of web APIs in the technology landscape today Microservices Architecture Enterprise Integration & Development Cloud Services (SaaS, PaaS, IaaS) Monolithic Application Libraries Any change required would necessitate a recompilation of the entire application. CORBA/IIOP SOAP REST ∞ Implementation was complex and sometimes non- implementable. Costly to implement. Inconsistent APIs across providers. Consistent approach for web services to make function calls using GET, PUT, POST, DELETE. Technological Advancements in APIs… As applications have become more distributed, technologies continued to evolve to allow for more scalable ways to develop APIs. Web APIs are now the forefront for web service communication between and within enterprise applications. Application Architecture Evolution

Process Orchestration Applications Data Infrastructure ESB Internal Web APIs Partner Gateway Business Partners Business Users Web Servers APIs – a programmatic interface into an application’s functions, data, or process that operates over a network. ESB – a software architecture model used for designing and implementing the interaction and communication between mutually interacting software applications. Process Orchestration – management of multi-interaction processes across business applications and people. Application – running instance of a business software program operated by a user or a running server program that responds to requests. Partner gateway services and web servers act as a pipeline, transferring information from the business to clients and business partners. Data – an application data repository. Infrastructure – the underlying foundation of the system, which includes basic support services and hardware. Architectural Components External Web APIs
