Cloud Hosting

Cloud Computing has become the buzzing topic of today's technology, driving mainly by marketing and services offered by prominent corporate organizations like Google, IBM & Amazon. Cloud computing is the next stage to evolve the Internet. Though for some people, "Cloud Computing" is a big deal, it is not. In reality, cloud computing is something that we have been using for a long time; it is the internet facility, along with the associated standards that provide a set of web-services to users. When users draw the term 'Internet' as a "cloud", they represent the essential characteristics of cloud computing.

Cloud computing is the latest generation technology with an extensive IT infrastructure that provides us a means by which we can use and utilize the applications as utilities via the Internet. Cloud computing makes IT infrastructure along with its services available "on-need" basis. The cloud technology includes - a development platform, hard disk, computing power, software application, and database. This technology doesn't require large-scale capital expenditure to access cloud vendors. Instead, the cloud facilitates 'pay-per-use,' i.e., the organizations' users have to pay only that limited amount to use the cloud infrastructure. In other words, cloud computing refers to applications and services that run on a distributed network using virtualized resources and uses the standard internet protocols for accessing.

Before learning about Cloud technology, readers must know about Networking, computers, database, etc. Terms such as operating system, applications, programs, and their meanings must be known before starting this.

The small and extensive IT companies follow the old traditions of managing IT infrastructure, i.e., server room, to keep all the details and maintain that server. In a word, it is a server room consists of database servers, mail server, firewalls, routers, switches, QPS (Query per second) & Load handler, and other networking devices along with server engineers. To provide such IT infrastructure, a huge amount of money has to spend. So, to reduce the IT infrastructure cost, Cloud Computing technology came into play.

Cloud computing technology brings a shift in the real paradigm of technology in the way systems are deployed. The massive cloud computing technology was enabled by the likeness & trend of the Internet & the growth of some famous multinational companies. Cloud computing makes the user dream come into reality by the concepts of 'pay-as-you-go', infinite scale architecture, and universal system available with high-speed and accuracy.

With the cloud's help, an organization or individual can start from low and small grade to a big name within a short time. So cloud computing is said to be a revolutionary change, even though the technology is still in an evolving stage. Cloud computing takes services, applications, and technology similar to the internet world and converts them into a self-service utility.

If we analyze the Cloud technology intelligently, we will see that most people separate the cloud computing model into two distinct sets:

These topics will have an elaborate discussion on the later chapters as each of them has their subcategories.
