The document discusses how using a private cloud platform like WSO2 Stratos can help organizations overcome challenges in enterprise application development by providing an integrated development environment that allows for self-service provisioning of projects, automated governance of libraries and frameworks used, and metrics on code quality and testing through integration with development tools. Stratos aims to provide an on-demand, automated solution for managing the entire application lifecycle from a centralized platform.

1. Using a Private Cloud to
Automate and Govern
Enterprise Development

2. Moore’s Law for Data
• The amount of data online went from
– 5 exabytes in 2002
– 281 exabytes in 2009
• Doubled every 15 months
• You cannot deal with this data growth with
the same applications
– A reasonable conclusion is that the number of
applications will double every 15 months too

3. Application Development is yet to have
its Industrial Revolution
The Industrial Revolution was driven by three key technologies:
• Componentization – making tools and products from re-usable, standardized components.
• Which relied on standardized metrics/measures so that components could fit together
• Factories – A large clean space where multiple parts of the production process could share light, power and
management to create consistency and governance.
• The IT industry is only just now reaching its industrial revolution. Open Standards are the metrics, Modularity
Code and SOA are the componentization. Platform-as-a-Service is the Factory.

4. Enterprise Application Development
Challenges
• Project Infrastructure takes too long to setup
• Too many projects fall through the cracks and use non-
standard infrastructure, build, governance
• Projects use too many different unknown or unapproved
libraries, frameworks, etc
• No clear idea of which projects are at which stage
• Few or no metrics on code quality, test coverage, re-use
• Little automated build or test
• Best practices are not applied everywhere

5. How does WSO2 help?
1. Create an effective Service Oriented internal
middleware
2. Expose key business function as a set of APIs
available in an Enterprise API Store
3. Manage, monitor and govern APIs (and services)
4. Create a Application Lifecycle Development and
Governance Cloud to build, test, and govern code
from inception to production
5. Deploy, run and manage applications in a private
Cloud Platform-as-a-Service

11. Integrating Development Management into Stratos
Project Jupiter

12. How does it work?
• A set of integrated systems – e.g.:
– Redmine, project management
– SVN, Git
– JIRA
– Identity Server
– Governance Registry
– Maven
– Stratos
• Integrated using ESB and Business Process Server
– Each system is connected via ESB
– Simple BPEL workflows orchestrate activities

13. Solutions to Challenges
• Project Infrastructure takes too long to setup
– Instant self-provisioning for new projects
• Too many projects fall through the cracks and use non-
standard infrastructure, build, governance
– Making it easy to self-provision encourages developers to use
the infrastructure
– A proven model in OSS: e.g. GitHub
• Projects use too many different unknown or unapproved
libraries, frameworks, etc
– Having a cloud builder allows governance on project libraries
– e.g. Import POM and analyze Maven POM in Governance
Registry

14. Solutions to Challenges
(continued)
• No clear idea of which projects are at which stage
– Automatic integration with a Governance Registry and standardized
lifecycles allows insightful reports
• Few or no metrics on code quality, test coverage, re-use
– Tools can be automatically integrated as part of the build –
Clover, Emma, Findbugs, etc
– All code is available in a central repository so external analysis
can be done
• Little automated build or test
– Automated build and test as part of the system
• Best practices are not applied everywhere
– Makes it easy to find best practices, analyze which teams do and
do not use them, and spread the word
