Cloud computing is rapidly evolving with the introduction of revolutionary container technologies. Virtual machine based deployments are now being replaced with containers, Infrastructure as a Service (IaaS) platforms are being replaced with Containers as a Service (CaaS) platforms and monolithic applications are being decomposed into microservices. The world is now moving towards a new era of cloud computing with containerization. Aligning with this movement, enterprises that are building cloud solutions may need public, private and hybrid cloud platforms. In this session Imesh will walk you through how WSO2 Cloud and Platform as a Service (PaaS) solutions can be used to build a complete enterprise cloud solution. The first half of the session will cover WSO2 Cloud features; application hosting, service hosting, microservice hosting, API management and WSO2 Managed Cloud features. The second half will cover how WSO2 middleware can be deployed on PaaS solutions based on Kubernetes, Mesos DC/OS, Cloud Foundry and OpenShift.

41. An Introduction to Cloud Foundry

42. An Introduction to Cloud Foundry

43. Limitations in the Current Architecture
• A container can only expose one transport/port.
• Only HTTP traffic can be routed via the router.
• SSL get terminated at the router.
• Internal routing rules cannot be defined.
• Autoscaling can only be done based on CPU usage.
