Apache Stratos

๏ Apache Stratos is a highly-extensible Platform-as-a-Service (PaaS) framework that helps run Apache Tomcat, PHP, and MySQL applications and can be extended to support many more environments on all major cloud infrastructures

๏ Stratos initially developed by WSO2 and last year donated to Apache Software Foundation

๏ After successfully complete the incubating process Stratos now graduated as Top Level Project

Demo - Basic Docker

๏ boot2docker

๏ Create basic container

๏ Write a dockerfile

๏ Build a docker Image

๏ Create a container using created docker image

๏ Access via host machine port

What is CoreOS?

CoreOS Cluster

CoreOS update management

What is Flannel?

What is Kubernetes?

๏ Kubernetes is a platform for hosting Docker containers in a clustered environment with multiple Docker hosts

๏ Provides container grouping, load balancing, auto-healing, manual scaling features ...etc

๏ Project was started by Google

๏ Contributors == Google, CodeOS, Redhat, Mesosphere, Microsoft, HP, IBM, VMWare, Pivotal, SaltStack, etc

Key Concepts of Kubernetes

๏ Pod - A group of Containers๏ Labels - Labels for identifying pods๏ Proxy/Service - A load balancer for Pods๏ etcd - A metadata service๏ cAdvisor - Container Advisor provides

resource usage/performance statistics๏ Replication Controller - Manages replication

of pods๏ Scheduler - Schedules pods in worker nodes๏ API Server - Kubernetes API server

Stratos Architecture with Docker Support

Kubernetes Resources Used by Stratos

● A Kubernetes Service is created for each transport/port mapping defined in the cartridge.

● Kubernetes Service is a load balancing service for Pods.

● A Kubernetes Pod is created for each member in a cluster.

● A Kubernetes Pod is a group of Docker containers.

● Kubernetes creates a separate Docker container for networking.

Introduction to WSO2 Private PaaS

Introduction to WSO2 Private PaaS

๏ The WSO2 Private PaaS is a complete, enterprise-grade solution, offering an open Platform as a Service (PaaS)

๏ At the core of WSO2 Private PaaS, lies Apache Stratos , providing cloud-native capabilities such as multi-tenancy, elastic scaling, self-service provisioning, metering, billing and resource pooling among several other functionalities

๏ More significantly, it also adds functionality to host pre-integrated, fully multi-tenant WSO2 Carbon middleware products as cartridges that deliver a range of cloud PaaS services
