Cloud computing refers to the on-demand access of computer hardware resources, particularly computer memory and processing power, to multiple users over a network. The term is normally used to describe remote data centers available via the internet. Such centers may be a physical location such as an office building, or it may be an on premise computer in a public area such as a college campus. While it is important for businesses to have access to these resources when it comes to data center optimization (DCO), the amount of resources that can be allocated to this type of workload is often quite substantial.
By offering such resources on a cloud computing platform, the business can benefit from the low cost and reliability of cloud computing. The main advantage of cloud computing is that there are no ongoing costs associated with maintaining and operating the infrastructure. This reduces the need to incur infrastructure costs, which makes cloud hosting ideal for many businesses.
There are several different types of cloud computing, and each has its own advantages and disadvantages. The most common type of cloud hosting is the web hosting type. With this type of service, a company can use software to manage its servers on a virtual infrastructure. This virtual environment can be controlled via an administrator’s account on a virtual server.
Some businesses may prefer to manage their servers themselves by employing their own IT staff, and outsourcing hosting to third party data centers. In some cases, a company might want to outsource web hosting only because they do not want to invest time and resources into managing this onsite infrastructure. This is particularly useful for companies that have limited onsite resources.
Cloud computing typically uses the concept of virtualization, where resources are split up between multiple users on the same physical machine. A user accessing a virtual server has access to the resources based on their login credentials. A user accessing a physical machine can gain access only to resources that the physical host grants. Resources granted to a virtual machine are referred to as virtual servers or virtual resources. Virtual resources are usually offered on a pay per use basis, similar to traditional shared hosting.
Virtualization is used extensively by businesses that need the ability to access resources hosted on the cloud. The advantage of this type of hosting is that they do not need to invest in equipment or hosting server space to provide their customers with access to those resources. Although there may be some initial costs associated with virtualized hosting, it is well worth it in the long run because it allows the business to save money and leverage its existing infrastructure resources for other uses.
Virtualization also allows a business to reduce hardware and network costs. Virtual servers use dedicated servers, or a single physical server, as opposed to several physical servers that are used by customers. Virtualization helps minimize the need for expensive equipment such as routers, switches, and IP phones. The entire hosting process is done through a software package, so it does not require the business to purchase additional hardware.
Another way that cloud computing benefits businesses is that it helps to manage their servers. It reduces the need for administrators to manage servers manually and allows them to focus on other aspects of the business. This is especially beneficial in large businesses that need more control over their servers.
Cloud computing allows a business to benefit from the speed of network connectivity. It reduces the need for a business to maintain its own networking infrastructure and allows it to focus on its core activities. This is particularly important for businesses that need a fast Internet connection. The flexibility of cloud computing is very valuable for businesses that need to deploy new applications or services that can not easily be installed and managed by a single administrator.
Cloud computing also allows a business to access its data resources from anywhere in the world. Many of its data resources are stored in the cloud, which means that a business does not need to keep up on data that it stores on its own.
Cloud computing allows a business to manage its network with the same level of efficiency as its own network, regardless of the distance between its servers and its data. Although a business can still have its own internal network for storage and routing, it can use remote access services to access its data from any location in the world, including a file cabinet or a desk at home. This reduces costs and allows businesses to gain the same level of service and reliability that it would get if it had its own dedicated network.
