4. INTERNAL ONLY | PRESENTER NAME 4 • Widely used and understood • Tested in real environments • Great tools support • ACID semantics • Great framework support • ORM like hibernate • Spring • JDBC Relational databases have served us well..
5. INTERNAL ONLY | PRESENTER NAME 5 But There are problems
6. INTERNAL ONLY | PRESENTER NAME 6 Problems • Complex object graphs • Schema Evolution with time • Semi-structured data • Difficult to scale • One solution for every problem
7. INTERNAL ONLY | PRESENTER NAME 7 Now we have choices.....lots of them
8. INTERNAL ONLY | PRESENTER NAME 8 We have to choose between what is right, and what is easy
9. INTERNAL ONLY | PRESENTER NAME 9 Polyglot Persistence Using multiple data storage technologies, chosen based upon the way data is being used by individual applications or components of single application. • Martin Fowler
10. INTERNAL ONLY | PRESENTER NAME 10 Polyglot Persistence – Probable Use Case
11. INTERNAL ONLY | PRESENTER NAME 11 Lots of companies are going this way.. • Facebook • Twitter • Google • StumbleUpon • LinkedIn • Lots of other companies..
12. INTERNAL ONLY | PRESENTER NAME 12
13. INTERNAL ONLY | PRESENTER NAME 13 What is MongoDB? • Document Oriented database • JSON-style documents: Lists, Maps, primitives • Schema-less • Each document is heterogeneous, and may have completely unique structure compared to other documents. • Fast and horizontally scalable • Rich query language
14. INTERNAL ONLY | PRESENTER NAME 14 MongoDB Terminology in comparison with RDBMS Database → Database Table → Collection Row → Document Index → Index
15. INTERNAL ONLY | PRESENTER NAME 15 MongoDB in Action > use notebook switched to db notebook > show dbs local (empty) > var notebook = {"name":"RedHat Developer Day Notes","desc":"Notes on RedHat developer day","author":"shekhar"} > db.notebooks.insert(notebook) > db.notebooks.find({"author":"shekhar"}) { "_id" : ObjectId("4fe1c495e89c1726c32b4966"), "name" : "RedHat Developer Day Notes", "desc" : "Notes on RedHat developer day", "author" : "shekhar" }
16. INTERNAL ONLY | PRESENTER NAME 16 Configurable writes : WriteConcern • Default : Fire and Forget • Other options • SAFE • Journal Safe • Fsync • Replica safe Speed is inversely proportional to Reliability

19. INTERNAL ONLY | PRESENTER NAME 19 Benefits of PaaS • Lets developer focus on his job i.e. to write code. • Reduce cost and time to market • You develop “Cloud Aware “ applications from bottom up. • Improve developer productivity. • PaaS can help achieve Continuous delivery
20. INTERNAL ONLY | PRESENTER NAME 20 As a developer it gives you power to prototype your ideas rapidly.
21. INTERNAL ONLY | PRESENTER NAME 21 Enter
22. INTERNAL ONLY | PRESENTER NAME 22 Introducing OpenShift • A free auto-scaling, cloud-based application platform from RedHat. • Multi Language, Multi Frameworks, Multi Cartridges. • Support Cloud Portability • No proprietary software. • Open source – OpenShift Origin
23. INTERNAL ONLY | PRESENTER NAME 23 Other facts • Command Line,Web, Eclipse , Forge plugin, and Spring Roo plugin. • Client Tools for data stores • Runs on top of EC2 but free • Supports 3 applications per user. • 40,000 files, 1GB of storage, and 512MB Memory per gear • Multi tenant • Shell Access.
24. INTERNAL ONLY | PRESENTER NAME 24 What's inside
25. INTERNAL ONLY | PRESENTER NAME 25
26. INTERNAL ONLY | PRESENTER NAME 26 Sign up for OpenShift Sign up at https://openshift.redhat.com/app/account/new
27. INTERNAL ONLY | PRESENTER NAME 27 Installing OpenShift client tools • Install Ruby 1.8 or above • Fedora / RHEL • yum install rubygem-rhc • Ubuntu • gem install json_pure • gem install rhc • Windows • Install ruby using Ruby installer • gem install rhc
28. INTERNAL ONLY | PRESENTER NAME 28 Only Prerequisite – Git
29. INTERNAL ONLY | PRESENTER NAME 29 Steps to deploy application on OpenShift • Create domain • Create application • Add cartridges – mongodb and mysql • Pull code from git repo • git push • Voila !! App is on Cloud
30. INTERNAL ONLY | PRESENTER NAME 30 Domain Management • Create domain by typing command • rhc domain create -n summit -l <login> -d • View the domain information • rhc domain show -l <login> • Update domain name • rhc domain alter -n summit-other -l <login> • Destroy domain • rhc domain destroy -n summit -l <login>
31. INTERNAL ONLY | PRESENTER NAME 31 Creating an application • To create an application • rhc app create -a notebook -l <login> -t jbossas-7 -d • Application will be running at • http://notebook-summit.rhcloud.com/
32. INTERNAL ONLY | PRESENTER NAME 32
33. INTERNAL ONLY | PRESENTER NAME 33 Pulling application source code • git remote add notebook -m master git@github.com :shekhargulati/notebook.git • git pull -s recursive -X theirs notebook master
34. INTERNAL ONLY | PRESENTER NAME 34 Adding MySQL and MonogoDB • rhc app cartridge add -a notebook -c mongodb-2.0 -l <login> • rhc app cartridge add -a notebook -c mysql--l <login>
35. INTERNAL ONLY | PRESENTER NAME 35 > git push
36. INTERNAL ONLY | PRESENTER NAME 36 If that was not enough.. There are lot of other goodies
37. INTERNAL ONLY | PRESENTER NAME 37
38. INTERNAL ONLY | PRESENTER NAME 38 Add Jenkins support • rhc app create -a jenkins -t jenkins-1.4 -l <login> • rhc app cartridge add -a notebook -c jenkins-client-1.4 -l <login>
