The cloud allows you to securely access your data from anywhere in the world, at any time, from any location. With access to important work information no longer being limited to your PC/laptop, you can now stay in the loop via your phone, tablet and even your watch!
A common example of a cloud service that you may have heard of is Office 365 from Microsoft. Many businesses use this service for their email (Outlook), as well as for document sharing, so that employees can access everything remotely. This is an example of the public cloud, which is just one of the options available.
