The most challenging part in using IaaS would be with respect to security. Usually security aspects require full control over the infrastructure. With the use of IaaS for security, the organization will have to cede the physical security of the infrastructure to the cloud service provider. This is not a major aspect and since the cloud service providers have a reputation to uphold they would be careful to provide the necessary physical security for the infrastructure. The organization should then be able to use their personnel to device the necessary 28 2 Basic Cloud Computing Types ϳϬй ϲϮй ϲϬй ϱϮй ϱϬй ϱϬй ϰϮй ϰϬй ϰϮй ϰϭй ϯϬй Ϯϴй Ϯϴй Ϯϴй Ϯϲй ϮϬй ϭϬй ϯй ƐĞ Ɛ Ɛ ŚĞ ƌh Kƚ Ăů Őͬ ůŝŶ Ɖ ^Đ ŚĞ ĚƵ ƚŽ ƐŬ Ğ ĞŶ ĚĂ ƌ ŽŶ Ɛ ĂƟ Ɖ Ɖů ŝĐ ŶƟ ŶƵ ŝƚǇ Ž ĞŶ ƚ D ĂŶ ŐĂ Ğŵ ůĞ ƐD ^Ă ŵ Ăŝ ů ƌĐ Z Śŝ ǀŝ ŶŐ Z W ŐĞ ƌĂ ^ƚ Ž Ǉ ^Ğ ĐƵ ƌŝƚ ŵ Ăŝ ů Ϭй Fig.
The cloud provides the ability to monitor many aspects of the service and thus have more data points to evaluate security. On the networking side, the true benefit from IaaS comes with the ability to deploy a variety of hardware from multiple locations to connect the various segments of the organization spread over a large geographical area. Since the service is a pay-as-you-go model, the ability to deploy the necessary infrastructure is facilitated by IaaS. It is worth noting that many organizations find the IaaS service as instrumental in reducing the pressure on their infrastructure.
Hosted private cloud is also referred to as Leased private cloud. In this model the organization pays a slightly higher cost for the use of dedicated servers. 7 Hybrid Cloud 33 to allocate these dedicated servers for other purposes during idle times, the customer’s utilization rate would be considered 100 % of the server time, irrespective of any lower percentage use. In this context we compare the cost details provided by Colgan and find out that the public cloud would be significantly cheaper than the private cloud because the infrastructure for the public cloud would be available for other uses whereas the private cloud infrastructure would not be usable for other purposes during any idle times.
