Overview
Why 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?
Upload
App to PaaS
Who are the Java PaaS players
Bitnami Cloud
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
Redhat Openshift
• Fast with openshift tools
• New offering
Google
AppEngine
• Use of Google BigTable for scalability but • Limited Java Support
weak support of SQL queries
by restricting to their
• Integration to Google API’s
own API’s
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
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
• Integration with other products you use.
– Web services availability
