Infrastructure-as-a-Service

“How do I use this?”

Servers in the Cloud

You must build and manage everything (OS, App Servers, DB, App, etc.)

Software-as-a-Service

“I’m not sure this does what I need.” You are restricted to the features of the 3rd Party application Someone else’s app in the Cloud (CRM, etc.)

Now in 3 Delicious Flavors

OpenShift Online

  • Traditional OpenShift
  • Red Hat provides everything
  • You sit back and relax

OpenShift Origin

  • You build it from Source
  • You put it on your infrastructure

OpenShift Enterprise

  • Red Hat provides the software
  • You provide the infrastructure

  • Operations care about stability and performance
  • Developers just want environments without waiting

OpenShift Enterprise creates a peaceful environment for both parties

  • Broker – Management host, orchestration of Nodes
  • Node – Compute host containing Gears
  • App – Your Application. An app contains one or more

gears, that contain one or more cartridges.

  • Gear – Allocation of fixed memory, compute, and

storage resources for running applications

  • Cartridge – A technology/framework (PHP, Perl,

Node.js, Ruby, Python, MySQL, etc.) to build applications

First Demo (Done on OpenShift Online)

  • 1. Create an app called farmstand
  • Note: can now add cartridges when creating app
  • 2. Look at URL of fresh app.
  • http://farmstand-tdawson.rhcloud.com/
  • 3. Make changes to our code locally
  • This is a local git repository we are changing
  • Demo uses a shortcut, use whatever way you want
  • 4. Push changes up to server
  • Notice how it will add the various language modules to

the app and then compile if necessary.

  • 5. See change in page
  • http://farmstand-tdawson.rhcloud.com/

Second Demo (OpenShift Origin, local VM)

  • 1. Steps done before we started the demo
  • Setup OpenShift Origin locally
  • Created a cartridge designed for an experiment
  • Installed the cartridge onto our OpenShift Origin
  • 2. Show we can make apps on our Origin instance.
  • 3. List what cartridges are available.
  • Note: We now have an experiment cartridge
  • 4. Build an app using the experiment cartridge
  • 5. Look at experiment default page
  • This is on my local machine, not publicly available.

Third Demo (OpenShift Origin, local VM)

  • 1. Ensure the user can expand their quota.
  • 2. Show how the user can use the web client to
  • Create a scalable app
  • Modify scalable settings after created
  • Change quota on a per app basis
