“I would trust no other company besides Nordisk Systems when dealing with my mission critical appliances.”--~Director of IT, Education--
Cloud service is a computing environment in which a user does not need knowledge of the physical location of computer hardware or the underlying hardware and software configurations providing the services. The cloud services provider supplies the data center, computing infrastructure, and management of these assets. Customers no longer have to worry about purchasing hardware and all of the costs associated with the hardware, because now they just pay for what they use.
There are three primary advantages to the cloud services model.
Cloud services are organized into three broad categories as follows:
SaaS - Software as a Service. SaaS is the delivery of application and system software functionality via the network. The cloud provider supplies the data center, computing infrastructure, and the software.
IaaS – Infrastructure as a Service. IaaS is the delivery of compute and storage resources via the network. A cloud provider supplies the data center and computing infrastructure.
PaaS – Platform as a Service. PaaS is the delivery of database management systems and middleware via the network. A cloud provider supplies the data center, computing infrastructure, the database management system, and middleware software.
