Cloud based services provide information technology (IT) as a service over the Internet or dedicated network, with delivery on demand, and payment based on usage. Cloud based services range from full applications and development platforms, to servers, storage, and virtual desktops.
Corporate and government entities utilize cloud based services to address a variety of application and infrastructure needs such as CRM, database, compute, and data storage. Unlike a traditional IT environment, where software and hardware are funded up front by department and implemented over a period of months, cloud based services deliver IT resources in minutes to hours and align costs to actual usage. As a result, organizations have greater agility and can manage expenses more efficiently. Similarly, consumers utilize cloud based services to simplify application utilization, store, share, and protect content, and enable access from any web-connected device.
“I don’t need a hard disk in my computer if I can get to the server faster… carrying around these non-connected computers is byzantine by comparison.” – Steve Jobs

Types of Cloud Services
All software and hardware required to build and operate cloud based applications are provided by the cloud provider via public Internet, VPN, or dedicated network connection. Users pay by use of the platform and control how applications are utilized throughout their lifecycle.
Software runs on computers owned and managed by the cloud provider, instead of installed and managed on premise. The software is accessed over the public Internet and generally offered on a subscription model.
Compute, storage, networking, security are provided by the cloud provider via public Internet, VPN, or dedicated network connection. Users own and manage operating systems, applications, and information running on the infrastructure and pay by usage.
