A private cloud is defined as a single tenant, dedicated hardware platform which runs virtualisation software to provide an organisation with facilities for running virtual machines and associated services. Given that the infrastructure is not shared, performance and compliance can be guaranteed, and full control of allocated resources is held by the organisation. This offers a significant advantage over public cloud solutions where many virtual machines may be competing for the same resources on the underlying platform.
Many existing private cloud deployments are on-site at an organisation’s own premises, requiring significant ongoing maintenance and staff expertise. In addition hardware refreshes of systems can be costly and difficult to implement. A hosted private cloud with a service provider is thus an attractive solution allowing an organisation to take advantage of higher service levels and the latest managed cloud infrastructure for a predictable monthly service fee.
Private cloud computing also offers a number of other benefits.
- If there is an increase in demand on IT systems, private cloud can scale to meet these demands, which offers companies a level of elasticity that they would otherwise not have.
- Organizations control their data, which ensures that all the information within the cloud is secure.
- Computing capacity is reduced by giving higher-priority tasks more power during peak hours.
- Companies enjoy reduced overhead because in a virtual data center, x86 servers and other related resources can be managed as a unit rather than separately.
- Most IT professionals today realize that this type of computing is the future. By investing in this technology, they’re helping their company prepare for the future.
With public clouds, on the other hand, suppliers manage applications and in order for businesses to utilize these applications, they need to pay a subscription or per usage fee.
Cost-wise, the private cloud is seen to be a cheaper alternative. For one thing, it can be build from an organization’s commodity hardware. The hardware that can be used can either be the desktop type or the server-grade which are of recent models. Vital considerations, however, include disk space, memory and processors that support virtualization.
Another advantage seen in this type of computing infrastructure is its locality feature. In short, a private cloud can be situated within your own datacenter or in your organization’s main property regardless whether it is on a different level of the building. This then makes it easy to transfer data compared to having your cloud hosted by a third party in another location.
What most businesses will like about having a private cloud is the security they will enjoy with all the data and applications they’re using. This is very possible for companies that have a private LAN. With no connections to other networks, security is always assured for the long term. It is important, however, to come up with the appropriate security measures within your organization such as in terms of giving access to certain people only.
