The cloud dominates many of those conversations and one key question tends to come up over and over again. What is it?

Simply put, cloud computing create virtual space that can be used over the internet. It possible for users to access data, applications, and services available . The cloud eliminates the need for costly hardware, such as hard drives and servers – and gives users the ability to work from anywhere. Over 90% of businesses are already using cloud technology in a public, private, or hybrid cloud environment. The major benefits of cloud include:

  • Availability: Get 24/7 cloud system access from anywhere, on any device
  • Elasticity: Scale up or down quickly to meet computing demand
  • Affordability: Only pay for what you use, and minimize hardware and IT costs
  • Simplicity: Free IT from managing servers and updating software
