DMG211- Using Red Hat’s OpenShift Platform-as-a-Service to Develop Scalable Applications on AWS Steven Pousty, Red Hat

November 13, 2013

Agenda • Start a demo • Cover some cool architecture • Go back to demo • We are going to see app creation, deployment,

and autoscaling LIVE!

Our application • We work for a vendor that sells souvenirs at

national parks in the United States and Canada • We are making a check in service to help drive

traffic to our stands • Doing a big national promotion which has the

potential to create A LOT of traffic • Due next week

Let’s go look at the application • http://parks-

winning.apps.reinvent.onopenshift.com • Written with:

– Java EE (aka the new Hotness) – Postgresql and PostGIS – Running on OpenShift – Load test with BlazeMeter

Using OpenShift Enterprise on Amazon Web Services • We retain control over how the “servers” are

configured • We control access to the data • We are NOT buying hardware • We are NOT racking and stacking • We get excellent efficiency from our AWS

purchase

What is PaaS (quickly)

OpenShift Products

Let’s go behind the scenes

• Take a tour of the PaaS from a DevOps perspective

Now a tour from a developers perspective • Create app • Create app with Eclipse • Create instant app • Make a code change • Look at our logs

Time to Check the Cake in the Oven

• Let’s see how scaling is doing

Conclusions • OpenShift helps Ops and Devs to “just get

along” through a standard interface • That interface provides:

– Developer Agility – Operational Standardization – Efficiency in IT

• With the efficiency comes: – Responsive apps, that auto-scale – Cost effectiveness
