4. TABLE OF CONTENT • API definition • API types • API Foundation • API Gateway pattern • Azure API Management service
5. API DEFINITION • Application Programming Interface, is a set of programming instructions and protocols used to enable communication between software applications. • API that facilitates interaction between different software programs by defining how they can communicate and exchange information. • Save time and effort that allow more rapid development and innovation.
6. TYPES OF API ARCHITECTURES • Rest APIs (Representational State Transfer): REST guidelines are: • Client-Server Separation. • Uniform Interface. • Stateless. • Layered system. • Cacheable. • SOAP API (Simple Object Access Protocol):defines how messages should be sent and what must be included in them. • GraphQL API: Developed by Meta in 2012 and open sourced in 2015, defined as a query language for APIs. • RPC: a protocol for invoking processes that can be written with XML, defined as a query language for APIs (XML-RPC) or JSON (JSON-RPC).
7. API MODERNIZATION APPROACHES API Strategy API Management & API Governance API Cost Model Developer Engagement
8. API STRATEGY • Critical component of digital transformation. Establish a digital strategy Align organization and culture Evaluation and build supporting tech Engage the current ecosystem •build a strategic view of AIPs and API vision. •API Mindset, leadership and investments. •Align right metrics in the digital value chain. •Maintain and optimize
9. API STRATEGY ESTABLISH A DIGITAL STRATEGY • The strategy is critical to the success of the rest steps. • Adopt a well-defined and executive-backed digital strategy. • Create an API ecosystem that focus on internal APIs first • Being open-minded to calculated risk is key for the strategy development process. • Identifying business outcomes • Identifying target audiences : • Visualize the API ecosystem. • Identify the internal and external participants. • Validate the ecosystem and business models
10. API STRATEGY ALIGN ORGANIZATION AND CULTURE • Assemble full lifecycle API management platform/tools • Establish API architecture and automation platforms • Commence KPI consolidation and dashboarding • Activate best practices for universal API management, governance, observability, and discoverability
11. API STRATEGY EVALUATION AND BUILD SUPPORTING TECH • Evaluate existing infrastructure. • Identify necessary technology. • Assess technology options. • Prioritize technology needs • Build support tech • Continuously evaluate and optimize
12. API STRATEGY ENGAGE THE CURRENT ECOSYSTEM • Developer experience • Developer outreach • Partner program • API marketplace • Innovation initiatives
13. API FOUNDATION • Frontend Integration • Backend Integration • API types: • Public API • Community API • Solution-Internal API • API Description
14. API GATEWAY PATTERN • Integration pattern for clients that communicate with a system service. • Provide a single abstraction layer between the underlying services and the customer’s needs. • Single entry point for all clients. When should you consider using the API Gateway pattern?
15. MAIN FEATURES OF API GATEWAY PATTERN Routing Request Aggregation Authentification Authorization Service Discovery Load Balancing Throttling Logging, Tracing Correlation Pas-Through Headers/ Query String Transformation Quality of Service Custom Middleware
