If you're unsure about what Cloud Computing is, you're probably among the 95% of individuals that are already using cloud services, like online banking and social networks, but do not realize it.

The "cloud" may be a set of various sorts of hardware and software that employment collectively to deliver many aspects of computing to the end-user as a web service.

Cloud Computing is that the use of hardware and software to deliver a service over a network (typically the Internet). With cloud computing, users can access files and use applications from any device which will access the web .

An example of a Cloud Computing provider is Google's Gmail. Gmail users can access files and applications hosted by Google via the web from any device.


How is computing from the Cloud different from computing from my PC's hard drive?
Unlike traditional computing where data is stored on your PC's local disk drive , the info within the cloud is stored on many physical and/or virtual servers that are hosted by a third-party service provider. An example of a cloud computing file storage provider is Dropbox. Dropbox files are often accessed from any device via the web .

What are public and personal Clouds?
A Public Cloud is predicated on the quality cloud computing framework which consists of files, applications, storage and services available to the general public via the web . Gmail is an example of a Public Cloud.

A Private Cloud is comprised of files, applications, storage and services that are implemented and guarded within a company firewall, under the control of a company IT department. An example of a personal Cloud would be a corporation that uses Microsoft Exchange because Microsoft Exchange can only be accessed by a licensed user through a secure VPN connection.

What are some common Cloud services and companies?
Some common services that are hosted within the cloud are hosted desktop, provided by companies like AT&T; hosted email like Gmail, provided by companies like Google; cloud storage, provided by companies like Dropbox; and streaming music, provided by companies like Spotify. These services, applications and files are stored within the cloud and may be accessed by users via any device.

There are a good range of companies and industry verticals that use cloud computing like Amazon and Google. Small, medium, and enormous size public and personal companies alike use cloud computing to scale back technology acquisition costs.

Do i want Cloud computing?
The Cloud Computing market continues to grow year after year because companies are getting more conscious of the value saving benefits of adopting the cloud.

With Hardware services, companies are ready to use the cloud service provider's equipment (storage, hardware, servers, and networking components) rather than spending large amounts of capital on equipment.

With Software services, companies' applications are hosted by the cloud service provider and are made available over a network saving costly deployment and maintenance costs.

Are my files safe within the Cloud?
While no storage solution is 100% safe, cloud storage providers offers a safer and more accessible place for companies to store data than traditional computing methods.

Depending on the contract , duplicate copies of the companies' data are often stored on servers located in several geographies and guarded by backup power supplies within the case of a disaster.

Today, many companies are moving to a Hybrid Cloud Computing model. With this model, companies are given the pliability of storing sensitive data securely during a private cloud while storing public data during a public cloud. Both infrastructures are kept as separate, unique entities.

What the Cloud is NOT?
The cloud isn't a fluffy white mass made from tiny water droplets floating in cyberspace. The cloud isn't impacted by weather changes like atmospheric pressure .

The cloud isn't an area during a single location. In fact, the cloud are often anywhere. The cloud are often in your companies' data center or hosted at a third party data center.

The growth of the cloud isn't being driven by "big business." the expansion of the cloud is being driven by consumers buying cloud ready devices which will hook up with cloud computing services at work, at home, and on-the-go.

The cloud isn't "a fad." There are currently 1.2 billion people using Facebook worldwide. That number represents 11% of the world's population.
Types of cloud computing
Not all clouds are an equivalent and not one sort of cloud computing is true for everybody . Several different models, types and services have evolved to assist offer the proper solution for your needs.
First, you would like to work out the sort of cloud deployment or cloud computing architecture, that your cloud services are going to be implemented on. There are three alternative ways to deploy cloud services: on a public cloud, private cloud or hybrid cloud.

1. Public cloud
Public clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources like servers and storage over the web . Microsoft Azure is an example of a public cloud. With a public cloud, all hardware, software and other supporting infrastructure is owned and managed by the cloud provider. You access these services and manage your account employing a browser .
2. Private cloud
A private cloud refers to cloud computing resources used exclusively by one business or organisation. a personal cloud are often physically located on the company’s on-site datacenter. Some companies also pay third-party service providers to host their private cloud. a personal cloud is one during which the services and infrastructure are maintained on a personal network.
3. Hybrid cloud
Hybrid clouds combine public and personal clouds, bound together by technology that permits data and applications to be shared between them. By allowing data and applications to maneuver between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options and helps optimise your existing infrastructure, security and compliance.
