The origin of cloud computing is unclear but however many people believe that it came from the use of the word cloud for the internet. However, if that was the case, then there is a contradiction somewhere. Cloud computing began to gain prominence in the 1950s when mainframe computers were in vogue. However, the diagrammatic use of cloud for the internet dated back to as early as 1994. No wonder, cloud computing has actually helped lots of activities done over the net and setting up a new trend in the field of web-hosting services. Many bigger organizations are gradually beginning to appreciate the benefits what cloud computing has to offer these days.
The word “internet” is often misconstrued by people to mean the same thing as web. Internet is bigger than the web but encompasses it. Internet is a system that connects different computers and users worldwide. Understanding this definition of internet will make you realize that the web is just a little part of internet. Email services and many others are also parts of internet. Companies’ websites are hosted in the internet; some companies connect particular users to their web through a special type of cloud computing called Software-as-a-Service, SaaS.
The internet cloud could be either public or private according to the way it is used as sold. Public cloud is a kind of cloud computing service that sells internet services to anyone that requires it across the web. There are many public cloud providers available today but Amazon Web Services (AWS) is the largest public cloud provider at present. Private cloud on the other hand supplies networks or internet services to specific or limited numbers of people. However, it is possible to use resources meant for public cloud to create private cloud. When this is done, the product is called virtual private cloud.
Cloud computing has three characteristics that are peculiar to it and these characteristics makes it notable.
This feature of cloud computing simply means that users of cloud or internet can demand whatever they want and it will be provided for them. You can decide to increase your service or reduce it at random.
Cloud computing also has the advantage of being sold on demand. This simply means that any amount of services can be sold to users on their request. Services can be bought per minute or per hour.
Cloud computing services are managed by the provider. The maintenance, administration and operations are done by the provider. The consumer only accesses these services through his personal computer and internet. Technological increase in the field of the internet has also caused high level of modernization and advancement of cloud computing.
Different types of cloud computing exists and they include as follows.
With these many types of services that cloud computing has to offer, it is definite that many bigger firms would find it really handy in incorporating it to their operating ways. As more organizations go on adopting this system, the scope for more expansion and research on the quality of services that cloud computing offers would be even better.
