Impact of cloud computing on enterprise Java applications

Will the hype around cloud computing end that day? Every day, new press releases are published in the media to touted some of the great services that PaaS providers have never heard of before, or to promote an article or research desperately if we cancel our data center and instilled If you become an IaaS Church or a SaaS Temple patron, then we all consider this incredible benefit as a treat and a cost-saving one. But aside all the speculation, and not to mention the real benefits of cloud-based technologies, the question is: How has the shift to cloud computing impact the typical build of enterprise Java application developers ?

At first glance, one might argue that the advent of cloud-based technologies really should not affect any Java developer. After all, the code written by developers, especially server-side, enterprise Java developers, should not be known where the code will be deployed. A Web Application Developed Using the Spring Model Whether it's being deployed to a JBoss server, a Tomcat instance, or to a WebSphere Liberty Profile server, application developers really do not care. Java code, written by a developer, is all that is fine as long as it passes all the required unit tests. Developers can then throw the code on the operating cubicle walls to handle complex cloud-based deployments and run-time management.

So, if the cloud does not necessarily affect the way the application is coded, what are the implications of cloud computing for application developers?

"The two biggest areas in which cloud computing affects application development are the tools developers use and the way they implement the application architecture," said Ryan Shriver, managing consultant at Dominion Digital. "Source control, continuous integration and automated test tools have been around for a long time before cloud computing came in. But now these tools are becoming easier to use than ever before. Find one of the servers and install it on top of it, Instead of downloading version control, figuring out how to add users and all such stuff, I can now go live, register for free, invite my friends, upload my code and leave. "

What is the end result of using these cloud-based tools? Maybe they do not really change the way developers write code, but they do help streamline the loading process and make the team more efficient because it does not require specialized People do code integration or run test suites before deployment. Ultimately, developers have more authority and are more comfortable with the process, resulting in more productivity.

Of course, the simultaneous existence of cloud-based modes of operation may not change when you write a servlet or write a JPA entity. In fact, the scalability of your runtime environment may actually solve some of the more complex programming problems. "If you have access to these resources that can be expanded or shrunk, you will have different ideas on how to solve certain problems," said Ryan. This could mean using Hadoop to handle results, or data management of big data, or even just how much less you worry about the data chart you're going to put into HttpSession, but for a given business question, whether cloud-based Whether technology is right or not, the truth is, enterprise developers need to know the capabilities cloud-based solutions provide and how to apply and apply their knowledge at the right time.

In fact, for many developers, the introduction or relocation of a PaaS provider to utilize IaaS does not necessarily change their day-to-day coding responsibilities, but that does not mean that they are isolated from emerging technologies in the cloud. From the tools they use, how do they implement the design and development of complex enterprise solutions, cloud computing has really changed the application development.
