Cloud is a style of computing where scalable and elastic IT-related capabilities are provided as a service using Internet technologies. WSO2 delivers one of the best Public Cloud, Managed Cloud and Private Cloud offerings with world renowned WSO2 middleware platform. WSO2 middleware stack is built from ground up with an open architecture for supporting cloud native features such as multi-tenancy, cluster discovery, artifact distribution, dynamic load balancing, autoscaling & monitoring to be able to run on any PaaS. WSO2 is now innovating on delivering a lightweight, ultra fast Gateway and a Microservices Framework for providing unprecedented agility and scalability in the cloud with Docker and Kubernetes. In this session Imesh will walk you through WSO2 Cloud strategy on delivering heterogeneous PaaS offerings, managed and public cloud platforms for building on-premise, public and hybrid cloud solutions.
