Internet technologies have provided a number of technological advances that all types of businesses have taken into consideration, but the changing technology revolution involves cloud computing. All businesses are moving from operating dedicated servers to execute all the computing needs in clouds.
The excitement of cloud services is evident. Let us look at an example from Charles Phillips Twitter, which describes how businesses are embracing cloud technologies. Some companies that are founded by Phillips helps businesses ditch their physical equipment and costly software development contracts in replacement of a monthly arrangement involving a group of resource and their expertise.
As there are many types of cloud deployment scenarios along with positive and negative aspect. Four typical deployment scenarios are described here.
This is the most widely used scenario of cloud computing. Public clouds are usually run by many large information technology firms, including Amazon, Microsoft, and Google, also involving massive data centers which are shared by equally massive and different users. These clouds are based on sharing all computer resources, including physical hardware as well as software technology behind.
Public cloud computing allows efficient use of economies and is customizable while also removing the need for software management and local server expertise. These public clouds are secure, so if your data is stored on the system and is not under your control in direct, the security mechanisms and degree of service assurance keep all the data and application safe.
A problem with the public cloud is that software platforms that are supporting it cater for broad audiences and lacks the degree of specialization. In the majority of cases, businesses may customize the public cloud, according to their needs, but it involves effort and cost. The alternate is the community cloud, in which businesses belonging to a particular niche sector collaborates to build platforms that serve the purpose.
For instance, banks and trading firms have some specific computing requirements that public cloud cannot serve that well. However, grouping up with cloud solution pr
oviders, these companies can make software and hardware solutions to cater their needs while sharing deployment costs across different businesses.
There are some businesses that are concerned with the loss of control and privacy that the cloud computing entails: their data is not stored on their premises, but in a server location where their equipment is pooled and shared. That is why, many organizations opt for a hybrid deployment, where their data and applications are retained as well as stored in-house, and IT requirements that are less business critical are made deployed to the cloud.
This deployment is more expensive as compared with the public cloud environment and allows business to pick areas they want to put forward for savings, and which they would like to keep control of. Cloud technology allows a degree of choice to where any particular business wants to draw a line.
There are cases, where data security requirements, as well as business needs, eliminate the use of shared computing infrastructure. It does not mean that the data is required to be stored on business premises, or the computing infrastructure needs to be managed by your staff. Think of buying services in private cloud environment.
They can also be managed by the third party, but virtual and physical computer resources are never shared. Private clouds are also operated by the company that is using them.
