what are the indepth process in cloud computing?
Cloud computing or a better descriptive phrase for business IT data networking- cloud networking, is a replacement for purchasing and managing physical servers. When an IT network service is required to start or be upgraded, the traditional step of an IT support resource is to eventually by a new server with 2 or more CPUs, multiple hard disks, RAM memory, etc; all physical items and some proven experience is required to do this process correctly for the intended IT service at the lowest cost, short and long term.
A cloud server is virtual compared with the physical server. Of course there must be a physical server to run or host a virtual server service. So a host system is the physical component and multiple cloud servers run as ‘guests’ on the host system. The host system is usually a serious collection of physical server components. An example host system is configured with 16 CPUs with 20 TBs of storage space on multiple hard disks and 100 GB of RAM. Such a device would be well over muscled for most corporate IT requirements however when the intent is to provide numerous cloud servers, excess physical components are required.
When a cloud server concept is considered, an IT support resource must consider to provide the physical AND virtual planning/deployment internally, or turn to an experienced outsource provider. Cloud server providers are not all the same and they mostly provision their cloud services via the Internet.
Some providers such as Amazon, provide the cloud virtual server(s) at a monthly subscriber cost, and this does replace the process of getting a physical server. Then the client must still provide the planning, OS install with licensing and other network service install and licensing and maintenance tasks. The IT service planning MUST take into account the cloud server is accessible across a WAN connection so performance and a possible Internet WAN upgrade may be necessary.
Other providers such as HSP Central (www.hsp-central.net), provide cloud servers which include ALL licensing of operating systems and applications and maintenance tasks. This complete cloud solution has the most advantages for any business. Small businesses (50 users or less) can access network services they could never afford outright. Medium and large businesses (50 users or more) can still take advantage of cloud servers by bringing the expertise and cost savings into their existing IT infrastructure. In any cloud scenario for this complete solution, this type of hosting service provides the host systems to run the cloud servers. All clients then become subscribers to cloud services and costs depends on how many virtual servers and how many users. Monthly costs will vary but typical IT budget savings range from 50% to 65% of the traditional physical server deployment.
Particular care in the planning for migration to a cloud server solution is quite important and this is not much different than the details of upgrading servers within an organization. Also, the long term cost savings more than make up for any planning adjustments to make a cloud server concept work properly.
