Cloud computing, simply referred to as “the cloud,” is the delivery of computing services—storage, servers, databases, software, networking, analytics and even more—over the Internet. Companies providing these computing services are said to be cloud providers and usually charge for cloud computing services depending on usage, similar to how you’re billed for electricity or water at home.
Cloud computing allows companies to consume a computer resource, like a virtual machine, an application or storage, as a utility — like electricity — instead of having to build and keep computing infrastructures in-house.
Consumer vs. Business
Here, we are talking about the cloud as it impacts personal consumers—those who are in small-to-medium offices or sit back at home and use the Internet on a regularly.
There is a different “cloud” with business. Some businesses choose just to implement SaaS (Software-as-a-Service), where the business directly subscribes to an application it accesses online. Also, there is Platform-as-a-Service simply put PaaS, where a business can produce its custom applications for use by the entire company. And do not forget the great Infrastructure-as-a-Service, where players such as Amazon, Google, Microsoft, and Rackspace give a backbone which can be “hire” by other companies. (For instance, Netflix delivers services to you since it is a client of the cloud services.)
Cloud computing is huge business: In 2012, the market generated $100 billion, which may be $127 billion by the end of 2017 and up to $500 billion by the year 2020.
Cloud computing is a very significant shift from the conventional way businesses think about Information Technology resources. What’s it cloud computing? And why is it so popular? Listed here are six common reasons many organisations are now turning to cloud computing services:
Many cloud computing services are given self-service, and on demand, therefore, even vast number of computing resources is provisioned in minutes, usually with just a few mouse clicks, offering businesses some level of flexibility as well as taking the pressure off planning.
Cloud computing removes the capital expense of purchasing software and hardware and setting up and operating on-site datacenters— the round the clock electricity for cooling and power, the racks of servers, the IT professional for managing the infrastructure.
3. Global scale
The benefits of the cloud services include the capability to scale elastically. That means delivering the correct amount of IT resources—for instance, more or less computing storage, bandwidth, power—right when it’s required and from the proper geographic location.
The largest cloud computing services which are run on a worldwide network of very secure data centers that are always upgraded to the latest generation of efficient and fast computing hardware. It offers many benefits over one corporate datacenter, which include reduced application’s network latency and higher economies of scale.
Typically, on-site data centers need a lot of “racking as well as stacking”— software patching, hardware setup, and other time-consuming Information Technology management chores. Now, cloud computing removes any need for these tasks. Therefore IT teams can actually spend time on gaining more critical business goals.
It makes disaster recovery, data backup and business continuity less expensive and easier because data can easily be mirrored at many redundant websites on the network of the cloud provider.
