Before we get into the technicalities of 2013 Java trends and its significance in cloud computing, let us at first know what cloud computing is all about. It can be defined as a particular phrase that is used to describe a wide range of computing concepts involving a chain of multiple computers that is connected through a real time or live communication network like Internet. Technically speaking, cloud computing can be defined as a synonym for distributed system of computing over a particular network. It also denotes the ability of running any program or application on multiple computers or work stations simultaneously.
This particular phrase is quite often used to refer to various network-based services, which are provided by the real server hardware and simulated by software systems running on single or multiple real time machines. There is no real life physical existence of these virtual servers. Hence they can be ‘moved’ from one place to another, scaled up or down on-the-fly without interfering into the activities of the end user. The phenomenon has somewhat similarity with a cloud that can grow larger or get smaller without really being a physical object.
As per the results of a recent survey that was conducted, cloud platforms have a propensity of reducing overall development time by 11.6% on average. This is mainly due to the ability of cloud platform to streamline the process of development and get the development assets online quickly. Besides, cloud platforms also come up with the capacity of collaborating on various developmental efforts, which is also an added advantage.
However, experts are of the opinion that platforms of cloud-based development in PaaS or LaaS clouds like Google, Microsoft, Salesforce, Amazon Web Services are still in their initial, (if not nascent) stage but are already showing a lot of promise through significant cost savings along with an array of superior efficiencies. At present, there are two extremely vital cases that make the concept of cloud computing so much popular – app dev test and big data. In case you do not have any program in place for exploring the value of this technology, you should at least have a clear idea about the advantages that you can enjoy:
- It has the ability to develop self-provision along with an environment that is suitable enough for testing, so that you can opt for structuring the application without the need to wait for any software or hardware to appear in the data center.
- It can get applications pretty fast into production. Besides, it can also scale the applications whenever needed.
- It can collaborate with other architects, developers as well as designers during development and structuring of the application.
Though the values are apparent, the technology behind it is sound and that is what makes the difference. At present, the developers can use eXo Cloud IDE for building, debugging, and deploying apps of App Engine without actually installing and configuring App Engine SDK or any of the so-called traditional desktop IDEs. Whatever happens takes place within the browser.
To debug and run an app on the development server, one needs to press Debug that can be found in Run Menu. Once that is done, the Debug window will come up at the lower end of the screen. Once that happens, it will be possible to open up the Java file and set the breakpoints in the margin at the left hand side.
Now, one can run the app by using the URL in the “Output’ tab. Once that is done, the execution will automatically stop at the breakpoints that have been set. Then there are the options of inspecting the variables, modifying their values during run time, adding conditions for creating conditional break points etc. With the eXo Cloud IDE deployment, debugging as well as running the App Engine apps are possible without installing and configuring App Engine SDK or Eclipse Plugin. As everything that is related to development activities actually takes place on Cloud IDE servers, it is possible to drastically reduce the initial setup time. Within just two-three minutes, one can comfortably get back to putting emphasis on issues that are more important – coding and refining the app.
