What is the cloud?

Moving to the cloud. Running in the cloud. Stored in the cloud. Accessed from the cloud: these days is seems like everything is happening “in the cloud”. But what exactly is this nebulous concept?

The short answer is that it's somewhere at the other end of your internet connection – a place where you can access apps and services, and where your data can be stored securely. The cloud is a big deal for three reasons:

• It doesn't need any effort on your part to maintain or manage it.
• It's effectively infinite in size, so you don't need to worry about it running out of capacity.
• You can access cloud-based applications and services from anywhere – all you need is a device with an internet connection.

This is important because there's a shift going on from office-based work to working on the move. This shift is reflected in computer hardware sales: In 2015 about 270 million desktop and laptop computers will be sold, compared to 325 million tablets and almost 2 billion smartphones.

That makes the cloud a very good place to run business software like customer relationship management (CRM) applications – software that users need to access reliably at any time, wherever they are, and on any device.

Cloud Computing is a network of remote servers hosted on the internet for storing and retrieving data.

It is also defined as The delivery of different services through the internet which includes tools and applications like data storage, servers, Databases, networking, and Software.
