Personal Cloud Backup in Mobile Subscription Services

Abstract

I was initially asked to deliver a presentation on Blockchain technology and Bitcoins. Following the presentation I got training of the technologies used in the PCB i.e. Personal Cloud Backup project. I was trained in Spring MVC framework, use of Eclipse Integration Development Environment, Junit, Mockito, SOAP UI, Mercurial, Jenkins, JIRA. I was assigned many tasks which enhanced my knowledge and experience. I then had a chance to work on the live project and fixed a cosmetic bug on web interface of the customer care console. I was also given an exercise to calculate the ‘Mobile Network Bankwidth’. Initially, I did this exercise and calculated the data manually which took about 20-25 minutes for 10 transactions approximately and later automated the process using Pattern and Regex matching libraries in Java and it reduced the data calculation time to a few seconds. I created a Java project and implemented the concept of ‘Pagination’ with my own business logic. After doing this I had a better understanding of the backend working of JSP, Servlet pages, database connectivity, hosting a server and I also learnt how to troubleshoot the connectivity problems between these using console and logging techniques. Another project was of ‘URL rewriting’. It helped me understand the use of url rewriting and I hosted an Apache Web Server on local machine and wrote rewriting rules to do tasks like, preventing the image hotlinking, display custom web pages on HTTP status, forbid a page from being displayed.
