Session presented at the 2nd IndicThreads.com Conference on Cloud Computing held in Pune, India on 3-4 June 2011. http://CloudComputing.IndicThreads.com Abstract: Cloud Foundry is the first Open PAAS platform project created by VMWare. CloudFoundry makes the life of developer easier by eliminating the time spent installing and configuring infrastructure such as application servers and JVMs. CloudFoundry is all about choices — you have choice of frameworks (Spring + Java, Rails and Sinatara for Rails,and NodeJs) , choice of Application Services (MySQL, REDIS, MongoDB) , choice of Clouds (vSphere , vCloud, AmazonEC2) to work with. The best part of CloudFoundry is that it does not lock you to a cloud provider and does not add any limitations( we all know how difficult it is to develop in Google App Engine). This talk will be divided into three parts : Introducing Cloud Foundry : In the first part I will first talk about what is CloudFoundry, why it was required, how you can deploy applications into cloud using CloudFoundry. Spring Roo Cloud Foundry Integration : Spring Roo is a RAD tool which helps you build spring managed applications very quickly and easily. Spring Roo latest version comes with inbuilt support for CloudFoundry. I will show how a application created using Roo can be deployed to cloud using CloudFoundry. Spring Roo + CloudFoudry is match made in heaven. WaveMaker : Recent SpringSource acquisition Wavemaker can help a non technical person create spring based application in minutes without writing code. I will demo how you can create an application using WaveMaker and deploy to the cloud.

6. Platform as a Service
PaaS provides the facilities to support the end to-end
life cycle of building and delivering web applications
and services.
PaaS = Computing Platform + Solution Stack
PaaS is for professional and business developers
To develop new applications “Cloud Aware” from the
bottom up.
PaaS is also called Middleware as a Service.

7. Issues with existing PAAS(GAE)

Can't run existing code.

Tied to particular environment.

Vendor lock-in (lack of cloud portability).

Deployment on public cloud only.

Need to change the mindset.

Diluted frameworks.

12. Choice of Developer Frameworks
12

13. Demo 1 – Spring Framework
Let's deploy a Spring Application
13

14. Choice of Application Services
14

15. Demo 2 – Going to Production
Let's replace hsqldb with MySQL
15

16. Demo 3 – Can I support both?
Wouldn't it be great if I can use hsqldb for
development and mysql for production?
16

17. Demo 4 – Play with NoSQL DB's
Let's play with Redis and MongoDB
(Using STS)
