Cloud Computing: Introduction
Cloud computing is something that is making noise in the world in Information Technology. As the name suggests, the cloud computing it includes everything that includes applications and services that run and are hosted on the Internet.
In reality, despite the fact that the term “cloud computing”Is somehow new, the concept itself is not that new.
We have already used cloud computing for a long time. Every time we use an application that is not found on our own computer, we make use of the services of cloud computing available on the Internet. We are all familiar with the email services provided by Gmail or Yahoo.
This is actually a service that we receive from the so-called “cloud computing.” So the first basic concept of cloud computing is simple:
the use of the services hosted somewhere on the Internet, on demand, instead of the permanent hosting services on our computer.
But what’s new in the cloud computing?
Why is it perceived as a new technology?
The rumor has been built lately due to the increasing use of the Internet by the world population, either for personal use or for companies and large companies. Increasing demand for services and applications that are somewhere in the Internet cloud, rather than our equipment, paved the way for new technologies, well suited for distributed computing power and distributed services, with a high availability to everyone, at any time. The service itself is maintained by the service provider.
The cloud computing service provider has what it takes to manage the service efficiently in order to allow access to the service by many users at any given time.
The provider has to use new high-speed interface technologies such as Infiniband, FiberChannel and Gigabit Ethernet, as well as computing technologies such as virtualization. Special platform softwares should be used to Maintain the scalability of cloud storage, also the provider should consider one of the main concerns of the users. the Aspect of the security of the information of the users.
All these capabilities, needs and features, and more, posed technical challenges that ultimately lead to innovative technologies in the field of cloud computing.
That corresponds to the technology cloud computing?
cloud computing Cloud computing is beneficial for users who need access to computing capabilities, or other services, on a random basis., It is beneficial as this service is too expensive to maintain permanently on local computers or computers laptops.
In addition to the fact that normal people have access to applications on the Internet (and in fact use cloud computing technology without being aware of it), cloud computing can be beneficial, for example, to students, who need more resources of computing that is not available by private teams.
In addition, the use of cloud computing is more beneficial for companies that, instead of improving and investing in their own IT infrastructure, can now, on-demand, have access to the various services and applications available in the Internet, and use them wisely, and reduce your IT expenses. This can be useful for research institutes such as universities, colleges.
In short, cloud computing paved the way for innovations and improvements in many technologies in the field of computing, in software and hardware infrastructure. Private users, as well as institutes, can benefit from cloud computing services, through the intelligent use of the services offered by this technology.
