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"

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?
Upload App to PaaS

So how does Java PaaS work?
12
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

13
Comparison of few
Pros Cons
Redhat Openshift Fast with openshift tools New offering
Google AppEngine Use of Google BigTable for scalability but weak support of SQL queries Integration to Google APIs Limited Java Support by restricting to their own APIs
Cloudbees Nice concept of DEV and RUN Low cost alternate to Amazon Beanstalk. More Agile Free scalable infrastructure with MySQL
Amazon Beanstalk Pure Tomcat on EC2 Flexible choices of databases Good access to other Amazon services

14
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 IDEs
  work with PaaS seamlessly.
• Use of build tools between Dev and Production
• Integration with other products you use.
• Web services availability
