Java Paas shootout   (@IBM developer)

Cloud computing is always a hot topic around IT field today.How can it bring to us ?How can it change our life? No answers...

"The Java ecosystem is rapidly expanding to support developers who want to build, test, or deploy Java applications on the cloud. Especially relevant is Platform as a Service (PaaS), in which the cloud provider delivers not only on-demand hardware and operating-system services, but also application platforms and solution stacks."

From the passage,we will know the author list three examples:Google Application Engine,Amazon Elastic Beanstalk, and CloudBees RUN@Cloud,and compare.

They have the same basic set of features(modern cloud computing features owned):

• Uploading and deploying application WARs
• Versioning deployed applications
• Testing and staging environments
• Online access to log files
• Automated monitoring and usage reports

They also have differences,u can learn know about them from this passage.

In our country,cloud computing is also a hot spot. There are many cloud computing services,like:

Ali Cloud：http://www.aliyun.com/?spm=0.0.0.0.vk92jN

Sina Cloud: http://sae.sina.com.cn/?m=front

Baidu Cloud：http://yun.baidu.com/

But personally, if we talk about the tech,we always go behind the others.Tech is based on the strong infrastructures and the creativity.We have both nothing,but i know we will catch step by step...
