Server to Cloud – convert a legacy platform to a micro-PaaS using Docker and related, containerization technologies
The talk will begin with how to setup a local Docker development environment (Windows or Mac OSX) as Docker runs atop Linux. The basics of Docker will be examined including how to use image repositories, and a brief description of available UI’s for managing Docker containers (Shipyard and DockerUI).
Next, example applications will be built for progressively more robust use cases and deployments; to demonstrate the power, flexibility and scalability of Containerization with Docker. The first example will discuss a simple two container model to encapsulate a database and application layer, which will lead to demonstration and discussion about more robust deployments that include features such as service discovery, automatic load balancing, and abstractions to simplify linking of containers. The context of the talk with be how Containerization enables architectural choice, scalability, and polyglot environments.
Docker and supporting technologies will be discussed to expose the multitude of supporting technologies within the ecosystem such as Flynn, Serf (makes or Vagrant), CoreOS, Deus, HAProxy and more.
Technologies that may be employed within containers during the demonstration include, Java, Scala, Akka, Docker, vert.x or node.js, memcached, mysql, mongo.
