• Players in this space• What are we comparing• Next Steps……

Have you heard of them??

OverviewWhy PaaS focus

2011 is "the year of Platform as a Service," and Gartner predicts, "By 2015, cloud platform experience will be a listed or demanded skill in most hiring decisions by IT software projects"

What is Java PaaS

• PaaS = IAAS + Middleware..

More about Java-PaaS

• In PaaS the provider delivers not only on-demand hardware and operating-system services, but also application platforms and solution stacks.

• PaaS services automate most of the IT management such as application deployment, including resource allocation, staging and testing, load balancing, database access, and access to platform libraries.

• PaaS multitenant architecture: multiple unrelated applications can run on the same hardware and software infrastructure, resulting in cost savings and more-efficient use of computing resources.

• Developers can focus on the application itself, as opposed to deployment and IT issues.

What does PaaS do or help us in?

Who are the Java PaaS players

Amazon Elastic Beanstalk

Sample – How does it work

So how does Java PaaS work?

Now what should we compare…

• Uploading and deploying application with ease• Versioning deployed applications• Having different environments for

development, stage and production• Online access to log files• Automated monitoring and usage reports• Access to other technologies

Comparison of few……Pro’s Con’s

CloudFoundry • Provides PaaS based on vmware• Supports Spring, Grails, MySQL• Has microcloud and is Open source

• Not all vFabric is available • Still WIP

Google AppEngine

• Use of Google BigTable for scalability but weak support of SQL queries• Integration to Google API’s

• Limited Java Support by restricting to their own API’s

Cloudbees • Nice concept of DEV and RUN• Low cost alternate to Amazon Beanstalk.• More Agile and opensource• Free scalable infrastructure with MySQL

AmazonBeanstalk

• Pure Tomcat on EC2• Flexible choices of databases• Good access to other Amazon services

OpenShift • Has two Redhat platforms – Express for developers and Flex for scalability• Supports Jboss framework / Opensource

• Still WIP

You can find more than what I covered

So what next??

• Spend time analyzing your current environment and PaaS vendor you want to move into. Few focus areas– Database – Moving your data easily between environments

• Developers should feel at ease in using IDE’s work with PaaS seamlessly.– Use of build tools between Dev and Production– Look at the frameworks they use like Spring, SEAM etc.

• Integration with other products you use.– Web services availability
