Understanding the basics of Cloud Computing

Updated on August 15, 2014

Cloud Computing

What is Cloud Computing

Before learning about Cloud computing, we should understand the definition of a Cloud in IT field. A cloud is a network or internet or anything which is at remote Location. Most of today’s applications run on a cloud for an example email, CRM, web portals etc. Cloud is generally used as a metaphor for the term “internet”.

In cloud computing you save all your data including files, software, applications etc. on a cloud server and access it from anywhere and anytime. This has brought a revolutionary change in the public and private sector where anyone can access data remotely.

Let us understand Cloud Computing with a small example. In traditional Banking, if you need some account details, you have to be physically present in the Bank but with the cloud computing technology you can access data from anywhere and from any device.

Now when the entire data is stored on the Cloud server you don’t need to visit the Bank you can easily access the requisite information from the cloud sever. This is beneficial for both the users and Businesses which saves time and money both. The best thing about cloud computing is that it works when you need it.

Cloud Computing Benefits

With cloud computing you don’t need any hardware device or backup systems to store Application, software or any kind of data; thus saving a lot of money. Moreover with cloud computing there is more control over data as it is up to you to decide who can access the data from the cloud and in what manner. Back in old days you require a complete data center with whole bunch of servers to store Applications, Software. But with the growing demand and the number of users it become very complex to maintain multiples apps at the same time and it was very expensive.

But with cloud computing you don’t need any kind of hardware you just will just need a cloud server to store your multiple apps, software’s or any kind of data. The major benefit of using Cloud computing technology is you don’t have to store the data in your hard drive. This technology has also enabled the employees of the company to work even when they are away from the office. There are different types of Cloud Computing services available depending on the needs of resources. The only concern with the cloud computing technology is the security issues.

Let us take a look at the features of Cloud Computing which will further help us in understanding the concept of Cloud Computing:

Broad Network Access

The capacities of a system are available through a network which easily allows users to access the cloud with the different devices like Computers, Laptops, MACS, Smart phones & Tablets. You can take an example of Mobile Banking which also runs with the Cloud Computing Technology.

Consumers are allowed to access the cloud from wide range of remote Locations. Broad Network Access includes private, public and hybrid clouds. In private cloud a company uses its own firewall and the access is limited to the employees of a company while in a public cloud the resources and the applications are available to the general public. Companies using hybrid cloud uses both the private and public computing to run their services.

On Demand Self Services

On demand services implies we can access the cloud resources anywhere and anytime. On Demand technology allow users to acquire the cloud resources on demand. This technology allows users to easily access the cloud resources for example Gmail, when you need to send or check mails you just need to Log in to your account and gain access to your data.

Rapid Elasticity

The best thing about the cloud computing the flexibility to use the cloud server’s i.e you can easily add or remove users, apps, data or other resources. User can also request for additional space and cloud resources are automatically available to the consumers. There can be three forms of scalability Manual Scaling; Semi automated scaling and elastic scaling:

Manual Scaling: In this environment resources are manually added to the cloud server according to a initial forecast. Most of the physical servers use this kind of technology.

Semi automated Scaling: Concept of virtual server’s plays a major part in semi automated scaling in which the resources are allocated according to the predefined set of images.

Elastic Scaling: Elastic Scaling is further enhancement of Semi auto mated scaling in which entirely removes the physical effort required to increase or decrease capacity. Everything in Elastic Scaling is controlled by triggers which automatically add or removes the capacity.

Measured Service

Cloud provider controls and monitors the services for multiple reasons like billing, usage of resources, access control, planning of capacity etc. In measured service the resources used can be measured both by the users and the cloud provider which provides transparency. In Cloud computing services measurement tools provide the details of usage to both the customer and the cloud service provider. The best thing about the measured service is that the consumer is only charged for the measured sum of usage.

Resource Pooling

Resource Pooling can be defined as the set of strategies used for categorizing and managing the resources on a Cloud. The resources are allocated to multiple users using multi tenant model. The consumer has no control or information of the Location of cloud resource.
