Infrastructure as a Service
What is Infrastructure as a Service – IaaS?
With IaaS (Infrastructure as a Service) customers rent space in a virtual data center from a provider and they access it via the Internet. This type of Cloud computing provides the basic elements of the system and customers only pay for the resources they actually use, by getting savings and the optimization of total IT cost. These resources usually include at least CPU cores, RAM, Hard Disk or Storage space, Virtual Network Switches, vLANs and IP addresses.
Users are then able to create servers and networks and tie them together forming architectures according to their needs, from the simplest to the most complex infrastructure. A IaaS vendor provides its users with the hardware and the provisioning software that allow them to work as if they owned a physical data center. In addition, the IaaS provider takes responsibility for the hardware and performs all the maintenance to ensure the servers run correctly.
