This document discusses Java Platform as a Service (PaaS) and compares different PaaS providers. It begins with an overview of PaaS and how it helps developers focus on applications rather than deployment and IT issues. It then discusses Java PaaS in more detail, including how it provides middleware and services for application deployment, resource allocation, and more. Major Java PaaS providers like Amazon Elastic Beanstalk are mentioned. The document concludes by outlining areas to consider when comparing and selecting a Java PaaS provider, such as databases, development workflows, and integration with other tools.

6. 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"

7. What is Java PaaS PaaS = IAAS + Middleware..

8. 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.

16. So what next?? Spend time analyzing your current environmentand 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
