The correct answer is C. IaaS. The ability to create a virtual machine on demand, whether from a standard image or from one you supply, can be very useful. Add the ability to pay for this VM by the hour, and it's even more useful. This approach, commonly known as Infrastructure as a Service (IaaS). IaaS (Infra
Question
Your customer is publically-funded university with approximately 13000 students and staff. The university is also home to a number of gaining and information studies research groups. The demand from researchers and students for access to servers is severely stretching the university technical resources. The university has started to use virtualization technology as approval for new physical servers was denied. The virtualization technology enables the IT team to offer staff and students to 60 virtual servers. However the new functionality is still insufficient to meet demand. You suggest that the university investigate moving to a small private cloud environment to streamline server provisioning. Students learn how to create maintain, or deploy operating systems, but is difficult to provide each student with a server and let them experience how a server works. Currently a class of 25-30 students may only have one or two servers to share among the class for the semester. It is hard to maintain the servers since before each semester all servers have to be reset. Virtualization is used, but this still requires a lot of manpower. Which Cloud delivery suits the university's needs?

Explanation
- The ability to create a virtual machine on demand, whether from a standard image or from one you supply, can be very useful. Add the ability to pay for this VM by the hour, and it's even more useful. This approach, commonly known as Infrastructure as a Service (IaaS). * IaaS (Infrastructure as a Service) is when the consumer does not deal with the infrastructure, instead the responsibility of the equipment is outsourced to the Service Provider. The Service Provider not only owns the equipment but will also be responsible for its running and maintenance, where the consumer will be charged on a `pay as you use' basis. IaaS is often offered as a horizontally integrated service that includes not only the server and storage but also the connectivity domains. For example while the consumer may deploy and run their own applications and operating systems, the Iaas provider would typically provide the replication, backup and archiving (Storage), the powerful computing requirements (Server) or the network load balancing and firewalls (Connectivity domains). Not B: * Communication as a Service (CaaS), enables the consumer to utilize Enterprise level VoIP, VPNs, PBX and Unified Communications without the costly investment of purchasing, hosting and managing the infrastructure. With the service provider responsible for the management and running of these services also, the other advantage the consumer has is that they needn't require their own trained personnel, bringing significant OPEX as well as CAPEX
