WSO2 API Manager provides cloud-native API management, where a user can expose microservices as managed APIs in cloud environments with no hassle. In an age where applications are increasingly adopting microservice architecture, it is obvious that container-orchestration systems such as Kubernetes have gained popularity due to the attractive functionality they offer to simplify a number of complex management tasks. With WSO2 API Manager, now you can expose microservices as managed APIs in cloud environments such as Kubernetes. It automates a number of complex tasks such as application deployment, scaling, and management. Exposing microservices in cloud environments with private jet mode provides a dedicated microgateway to handle each managed API. This will provide maximum security and guaranteed resource allocation for API execution. By attending this webinar, you will gain hands-on experience on how to expose microservices as managed APIs in cloud clusters in private jet mode where each API is managed by a dedicated microgateway.
