[DevoxxBE2013] OpenShift Primer: Get Your Applications into the Cloud
Eric D. Schabell, JBoss technology evangelist at Red Hat, demystifies OpenShift, a PaaS revolutionizing cloud deployment for Java EE, PHP, Ruby, and beyond. Author of the OpenShift Primer e-book, Eric—drawing from his integration and BPM expertise—guides attendees through rapid app migration, showcasing portability without code rewrites. His action-packed session deploys a Java project in minutes, contrasting OpenShift’s ease with cumbersome VMs.
OpenShift’s open-source ethos, Eric argues, delivers developer freedom: Git-based workflows, auto-scaling gears, and cartridge-based runtimes. From free tiers to enterprise scalability, it transforms cloud adoption, with European data centers addressing latency and privacy concerns.
Demystifying PaaS and OpenShift Fundamentals
Eric contrasts IaaS’s VM drudgery with PaaS’s streamlined abstraction. OpenShift, atop Red Hat Enterprise Linux, provisions environments via cartridges—pre-configured stacks for languages like Java.
He demos creating an app: rhc app create, Git push, and instant deployment, emphasizing no vendor lock-in.
Rapid Deployment and Portability
Portability reigns: Eric deploys a legacy Java EE app unchanged, leveraging JBoss EAP cartridges. PHP/Ruby examples follow, highlighting multi-language support.
This agnosticism, Eric notes, preserves investments, scaling from localhost to cloud seamlessly.
Scaling, Monitoring, and Security
Auto-scaling gears adjust to loads, Eric illustrates, with hot-deploy for zero-downtime updates. Monitoring via console tracks metrics; security integrates LDAP and SSL.
For Europe, Irish data centers mitigate latency, with GDPR-compliant options addressing data sovereignty.
Why OpenShift? Open-Source Advantages
Eric’s pitch: unmatched ease, no code changes, and open-source values. Free tiers on AWS East Coast suit demos, with paid plans offering local regions like Ireland.
He invites booth chats, contrasting OpenShift’s speed with competitors’ rigidity.
