1. Kubernetes Gateways: Crafting Seamless Cloud-Native API Management Architectures December, 2023
2. Hello! Pubudu Gunatilaka Senior Technical Lead, WSO2 pubudug@wso2.com
3. The Journey Through Time: The Birth of API Gateways 3
4. The Role of an API Gateway 4
5. The Foundation: Traditional API Management Architectures 5
6. API Creation Workflow in the Traditional Model 6
7. The Cloud-Native API Paradigm
8. • Kubernetes: The cloud's operating system and container orchestration platform. • Automates deployment, scaling, and management of containers and microservices. • Enables automatic load balancing, scaling, and self-healing for applications. • Provides a unified framework for cloud-native application management. • Streamlines resource utilization and supports multi-cloud portability. Kubernetes: The Cloud's Backbone 8
9. Key Challenges: • Monolithic Design • Incompatible Infrastructure • Limitations in Leveraging Cloud Benefits • External Dependencies • Limited Support for Microservices • Complex Configurations and Maintenance • Scalability Bottlenecks Traditional API Management Meets Kubernetes 9
10. Breaking the Mold: Rethinking API Management Architectures
11. • Continuous Development and Open Source Benefits • Envoy as an Ingress Controller in Kubernetes • Essential API Management Features • Support for REST and gRPC Services • Extensibility options to enhance and customize its capabilities • Flexible Deployment Patterns Empowering API Gateway Transformation with Envoy Proxy 11
12. The Cloud Native API Management Architecture 12
13. • API Standardization: Aims to standardize and streamline API gateway management in Kubernetes. • Simplified Configuration: Common interface for easier setup and maintenance. • Enhanced Interoperability: Smooth integration with different gateway implementations. • Dynamic Automation: Dynamic configuration, scaling, and service discovery. • Seamless Kubernetes Integration: Effortlessly works within the Kubernetes ecosystem. • Community Collaboration: Driven by a diverse developer community for continuous improvement.

14. Kubernetes Gateway API Standardization… 14
15. As An API Developer 15 apiVersion: gateway.networking.k8s.io/v1beta1 kind: HTTPRoute metadata: name: products-route spec: hostnames: - "gw.apis.com" rules: - matches: - method: POST path: type: RegularExpression value: /products filters: - type: URLRewrite urlRewrite: path: replaceFullPath : /productsList type: ReplaceFullPath - type: RequestHeaderModifier requestHeaderModifier : add: - name: x-product-list value: "All Products" backendRefs: - name: products-microservice port: 8080 Kubernetes Custom Resource - HTTPRoute
16. The API Developer and API Product Manager Perspective 16
17. Single Control Plane for Diverse Gateways 17
18. API Gateways evolving into a vital but commoditized part of infrastructure. 18
19. • Shifting Developer Focus: ⦿ Developers are freed from the complexities of gateway management. ⦿ Can focus on building and maintaining APIs and core development tasks. • Key API Management Features: ⦿ API Lifecycle Management ⦿ API Governance ⦿ API Marketplace ⦿ API Version Management ⦿ API Insights… • Try out WSO2 APK (API Platform for Kubernetes) - https://wso2.com The Changing Tides: Shifting Focus to API Management 19
