This document summarizes an upcoming WSO2 workshop on APIs, integration, and microservices. It provides an overview of the WSO2 middleware platform and its key components for API management. The platform is fully open source and includes products for API publishing, a developer portal, gateway, security, analytics, and an enterprise service bus for mediation. It supports both on-premise and cloud deployments and is highly scalable and extensible. The workshop will cover API strategies, architectures, deployment models, and demonstrations of the platform components.

5. Life Cycle

6. The API
6
Definition : An API is a business capability delivered over the Internet (+ any medium)
to internal or external consumers.
• Network accessible function
• Available using standard protocols (mostly web)
• With well-defined interfaces
• Designed for access by third-parties
.

7. Managed API
7
Definition : An API is a product. Product should be able to manage.
• Actively advertised and can be subscribed
• Available with SLA
• Monitoring enabled – Gain insights visualize through dashboards
• Enables monetization
• Secure Access – OAuth2, JWT token validation, and IP filtering
.

8. API Strategy
8
• API as a Product vs API based products
= API as a strategy vs API as a tactic
• External API management vs internal API management
• Developer ecosystem – API ecosystem vs cloud-devops
• API management and the enterprise
• Business model – Pay as you go, revshare, freemium,..

9. Characteristics of a Business API
9
• Protocols and styles – Passthrough only
• API as the main product
• API as the brand
• Business model – monetization
• API Statistics
• Authentication and Authorization
• Throttling
• Caching
• Deployment model

10. Architectural Factors
10
• Deployment model
• Deployment, access token caching,...
• On-premise vs cloud vs hybrid, Cloud to enterprise access
• Federated architecture
• Large scale APIs
• Edge API management

11. WSO2 API Management Platform
• 100% Free and Open source ( Apache 2.0 license)
• Supports On-premise and Cloud deployment
• Feature rich, and improving…
• Extensible by Design, and highly Scalable
• The Platform advantage for an End-to-end Solution
