Computers & IT (Non-Engg)

Hi,
I feel really good to see lots of interesting questions to answer one after another. Thanks to you for asking this.
In next five years, you will see companies alloting very tiny space for their server room, SMEs and startup companies they will be completely engrossed in their product improvement and business development and what about their IT infrastructure? Everything will be taken care by cloud computing providers for sure. The Iaas, Paas model will support their applications and Saas product with salable, 100% up time even way better performance.
Companies won't be worried about even any downtime because DevOps and automation will take care this headache with Docker container model combination with Python, Jason, chef script.
The big data, SAP HANA will rule the world in order to a large scale of analytic and no SQL model. It will be far easy to analysis large Logs even 1 TB data analysis. AI/ Machine learning, IoT will bring a completely new paradigm shift. You and I will have maybe 1 GBPS internet connection to connect our gigantic infrastructure and manage without any system admin because everything will be server less and orchestration model.

The Commerce is the nerves center of each organisation. The strength or the health of the organisation is ultimately measured by its economic stability or the reserve.
As in case of the Engineering production center marketing is major object. Today the Technology is so much available anything can be developed but selling is very difficult.
Likewise in order to know where the industry or organisation or institutions are heading towards is only ascertained by its Commercial analysis
Commerce/Accounting/ Finance/Business Management all have tremendous career opportunities. A combination of Bachelor/Master Degree + ERP knowledge would be highly advantageous. One can concentrate more on ERP study and it is the need of the hour for advanced applications for a growing business having global presence. SAP, Oracle and Navision, etc. have been more focused and continuously engaged with ERP apps.
Know one thing, without a sound ERP system, company cannot excel. ERP is the spine of any enterprise. However advanced solutions these ERP companies have already launched, still there is a demand for newer applications. If technology advances, correspondingly ERP should also advance. Otherwise the business will fail. Who had thought, decades back, raw material will be procured from India, a few parts would be manufactured in China and assembled in Malaysia and sold in the US and having a distributing hub in the UK and main agent operating from Germany and the owner company is occupied in Italy? Imagine the complications? Now without a sound ERP, can this be possible? Will the end customer receive his goods intact for the competitive price, on time and best quality? Shouldn't we thank giant ERP companies for their robust applications to handle such intricate business scenarios and support complete procurement or sales cycle?
Executives want to see day-to-day reports in their cell phone. Yes, it is achieved already, but at what cost? How many companies have implemented? Why it is not made simple? Why can't we have plug and play solutions and Android phone? Think about it! There are many such inventions taking place and you be a part of it! Isn't it interesting and brilliant career?

Mainframe computing - Flexible infrastructure that can support virtualized environments; scalable support for big data analytics and new applications; simple migration processes; and reduced total cost of ownership compared to a private cloud. The advantage of mainframe computing is higher reliability. If an internet connection goes down, or if the host servers go down, the client will be unable to access its data.
Cloud Computing - Scattered across many individual servers; cloud can be accessed from anywhere, businesses can increase access to the server as they grow simply by adding further clients. They can even extend this access to mobile devices. On cloud service provider, you're effectively putting your trust in that service provider that your data will be safe, as it will be kept on servers that are owned by them.
