Creating a Scalable and Decentralized API Management Architecture with WSO2 API Manager
1 like368 views
The document discusses creating a scalable and decentralized API management architecture using WSO2 API Manager, emphasizing the shift towards microservices for improved agility and autonomy within teams. It outlines the architecture's components, including API creation and deployment phases through tools like Kubernetes and Jenkins, and presents different deployment modes for APIs. A live demo and future webinars are also mentioned as resources for further exploration of the topic.

- 16. Why Decentralized API Management Architecture? ● Modern application development practices mandate a more decentralized approach ● Improve productivity and agility by giving teams more autonomy to self-serve ● Microservice philosophy also favours decentralization in all aspects of software design ● At a high level, it is about giving the business greater agility when bringing new ideas to market
- 18. Solution Stages ● API Design Phase: ○ API Creator ■ WSO2 API Manager, Github ● API Approval Phase: ○ API Product Manager ■ WSO2 API Manager, Github ● API Deployment Phase: ○ Fully automated ■ Jenkins, Kubernetes with API Operator, apictl
- 19. API Design Phase ● API Creator designs the API
- 20. API Design Phase ● Use apictl(Command Line tool) to export the API from the API Publisher. ○ You can also download the Swagger definition from the API Publisher. ● Commit the API artifacts to the personal Github Repo. apictl export-api -n Online-Store -v 1.0.0 -r admin -e development git commit -a -m “Adding OnlineStoreAPI” git push origin store-apis ● Make a pull request for API Product Manager’s approval
- 21. API Design Phase ● Github branch structure Github Branch Name food-apis sms-api location-api API Name(s) food-delivery-api sms-api location-api pizza-api restaurant-api API Microgateway 1 API Microgateway 2 API Microgateway 3
- 22. API Approval Phase ● Review and merge the pull request by the API Product Manager ● Login into the API Publisher and publish the API
- 23. API Operator for Kubernetes ● Makes API a first class citizen in Kubernetes eco system ● Easier to deploy ● Imposese ○ Security ○ Throttling ○ Mediation ○ Monitoring For your microservices ● Build in deployment patterns ● Fully automated experience for cloud native API management ● Single source of truth
- 24. API Operator Overview API CRD API Controller API Operator K8s API Server Docker Registry apictl add api -n products-api --from-file=products_swagger.yaml
- 25. API Deployment Phase ● Github release in the respective branch (eg: food-apis-v1.0.0) ● Jenkins job triggers for the release of food-apis-v1.0.0 ● Using apictl (command line tool), add an API in Kubernetes using the API Operator for Kubernetes ● Deploys an API microgateway in Kubernetes ● Ingress resource will be created
