Transcript

1. Closed PaaS to Open PaaS Migrating Google App Engine Apps to OpenShift PRESENTED BY Shekhar Gulati
2. AGENDA • Introductions • Overview • What is CapeDwarf • OpenShift Ecosystem • Demo
3. WHO AM I? • Shekhar Gulati • OpenShift Developer Evangelist at Red Hat • 8 years of software development experience • Learning JavaScript these days :) • Java / NoSQL/ Cloud • Loves to learn and try new technologies • Twitter Handle : shekhargulati • Github https://github.com/shekhargulati • Slides https://speakerdeck.com/shekhargulati
4. WHO ARE YOU?
5. • We all know Google App Engine, right? – Google's platform to build web applications on the cloud. – Supports Java, Python , and Go – Automatic scaling and load balancing – Transactional data model based on Big Table – Additional features like Mail, XMPP, Google Accounts, Cron, Memcache, Image, etc. GOOGLE APP ENGINE
6. • API • The services behind • Scalability , reliability, size, price,... ITS ALL ABOUT
7. Google App Engine is Great But ...
8. • Can't port existing applications • Requires change in mindset • Lock-in • Platform limitations like write to file system • Deployment environment does not replicate the same restrictions of the Production • Not open source • Every GET or POST from the one server to other, is aborted if it has not finished within 10 seconds • Pace of innovation is very slow • Public cloud only GAE LIMITATIONS
9. What if you could get Java GAE for free?
10. • Java GAE for Free • Easy setup • Debug support • Multi node • Migrate data Now you can == JBoss CapeDwarf CAPEDWARF
11. • Drop in replacement for GAE – Take an existing GAE app and drop into JBossAS env – It just works • No vendor lock-in • Enable cluster debugging / testing • On-premise cloud CAPEDWARF GOALS
12. • CapeDwarf implements GAE API on top of JBoss and other open source libs • It runs on top of JBoss AS7 subsystem HOW DOES CAPEDWARF WORKS?
13. • Big Table → Infinispan • Tasks → HornetQ • Search → Lucene and Hibernate • Blobs → GridFS • Clustering → JGroups • XYZ → OSS or DIY CAPEDWARF TECHNOLOGY CHOICES
14. OpenShift is PaaS by Red Hat Multi-language, Auto-Scaling, Self-service, Elastic, Cloud Application Platform
15. Lowers Cost Improves Developer Efficiency Scales WHY PAAS?
16. origin Public Cloud Service On- premise or Private Cloud Software Open Source Project FLAVORS OF OPENSHIFT
17. Developer IDE Integrations Web Browser Console Command Line Tooling REST APIs INTERACTIONS
18. 18 https://openshift.redhat.com/app/account/new Promo code is JUDCONBR13 CREATING OPENSHIFT ACCOUNT
19. • OpenShift is free-as-in-beer & free-as-in-freedom • You get three free gears, each with 512MB memory and 1GB of disk space. • Need more resources, just ask! • The catch is we are in developer preview right now WHAT DO I GET?
20. 20 ➢ Login to OpenShift web console ➢ Click on “My Account” ➢ Namespace – JUDCONBR13 – Unique per user CREATING NAMESPACE
21. 21 Some terminology for today 1. Application – your web code and any data store. Has to be on 1 or more gears 2. Gear – is like a server. It can have only 1 language for the web programming. 3. Cartridge – it adds a language, a data store, or other functionality 4. Git – used for version control and managing code between server and your development machine 5. Ssh – command line tool to connect to your gear
22. 22 Install Ruby 1.8.7 or greater Install Git Install rhc OpenShift gem Refer to documentation INSTALLING CLIENT TOOLS
23. 23 rhc setup -l <openshift_login> -> creates namespace -> upload ssh keys SETUP OPENSHIFT ENVIRONMENT
24. 24 OPENSHIFT CAPEDWARF QUICKSTART
25. 25 CAPEDWARF APP
26. 26 CLONE REPO $ rhc git-clone -a todo
27. 27 Look at template application
28. 28 $ git remote add upstream https://github.com/shekhargulati/todo- capedwarf.git $ git pull -s recursive -X theirs upstream master PULLING THE CODE
29. 29 $ git push PUSHING CODE TO CLOUD
30. QUESTIONS?
31. DONE!
