What is Cloud Computing

In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet.

Cloud computing is defined as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. Cloud computing is comparable to grid computing, a type of computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine.

There are several types of cloud:

Private Cloud

This cloud infrastructure operates solely for an organization. It signifies a service and infrastructure being maintained on a private network, helping to offer great levels of security and control. However, it does require companies to purchase and maintain all the software and infrastructure, helping to reduce cost savings.

As a result, private cloud is best for businesses with dynamic or unpredictable computing needs that require direct control over their environments.

Reasons for choosing the Private Cloud are:

• Your business is your data and your applications, which means that control and security is of high importance.

• Your business is part of an industry that requires you to stick to strict security and data privacy.

• Your company is large enough to run a next generation cloud data center efficiently and effectively on its own.

Public Cloud

A Public Cloud is where the services and infrastructures are provided off-site over the internet. Although helping to provide the greatest level of efficiency in shared resources, it also tends to be more delicate than private clouds.

A public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.

The main benefits of using a public cloud service are:

• Easy and inexpensive set-up because hardware, application and bandwidth costs are covered by the provider.

• Scalability to meet needs.

• No wasted resources because you pay for what you use.

Hybrid Cloud

This cloud infrastructure offers the benefits of both. The Hybrid Cloud is a mix between the public and private options. You have the ability to spread things out over a hybrid cloud, allowing you to keep each aspect of your business as efficient as possible.

Hybrid cloud is particularly valuable for dynamic or highly changeable workloads. For example, a transactional order entry system that experiences significant demand spikes around the holiday season is a good hybrid cloud candidate. The application could run in private cloud, but use cloud bursting to access additional computing resources from a public cloud when computing demands spike. To connect private and public cloud resources, this model requires a hybrid cloud environment.

Another hybrid cloud use case is big data processing. A company, for example, could use hybrid cloud storage to retain its accumulated business, sales, test and other data, and then run analytical queries in the public cloud, which can scale to support demanding distributed computing tasks.
