WHAT IS CLOUD COMPUTING?

Cloud computing is an arrangement in which computing resources are delivered as a service over a network connection, most of the time the Internet. Cloud computing service fully depends on sharing a pond of physical as well as additionally virtual resources, instead of dispensing personal or system based hardware, application and software. Cloud computing is to some extent similar to the term utility computing because in this environment users are capable to take advantage of a supply of computing resources instead of deal with the tool required to produce it on one's own.

REASONABLE PRICE

In Cloud Computing arrangement users only have to pay for the resources they utilize, so they don’t need to pay for the unused resources, due to this it is available at reasonable rates

Highly SCALABLE

It is highly scalable because of automatic increase and decrease of resources based on the needs, therefore ensuring the higher level of security.

BENEFITS FROM HUGE ECONOMIES OF SCALE

In cloud computing model numerous of services can be setup utilizing the same available computing resources.

MORE RELIABLE OPTION

As services are hosted over various different servers so any individual system breakdowns don’t influence the performance and progression of the service.

HIGH FLEXIBILITY

It is an excellent option from the security and the level of management along with the option to match the needs of any business.

Various Uses of Cloud Computing

Most probably you are using one of the cloud based technology at this moment but you do not even know it. In case you use any online solution to store documents, play music, send or receive emails, watch TV, play online games, use mobile or anything else, most probably cloud is the technique making it possible for you. Cloud based services are in the industry from a decade and there are several kind of organizations and businesses from small, mid to large organizations and enterprises as well as government agencies are taking the benefits of cloud technology. Given below are the few crucial things you can perform using Cloud computing:

How Does Cloud Computing Works

Cloud computing services works in a differ way, depending on the service provider you choose. But several best cloud service providers provide a friendly, easy-to-use, web based dashboard that makes it much simpler and effortless for webmasters and web developers to administer their accounts and resources. Few cloud computing based solutions are likewise are intended to work properly with REST (REpresentational State Transfer) APIs and a CLI (Command Line Interface) giving web developers and coders several choices.

Various Types of Cloud Computing

Basically Cloud computing works on three models, public Cloud, Private Cloud and Hybrid Cloud.

Public Cloud

A public Cloud model is where services and related infrastructure are hosted off-site by a cloud solution provider, shared over their customer base and got to by these customers publically accessible networks, for example, the world wide web. Public cloud model is an excellent economies of scale along with redundancy yet these are highly unprotected and unsecure than private cloud models because of increased accessibility and ease of use.

Private Cloud

Private cloud model utilize pooled services and framework put away as well as kept up on a private network, even if physical otherwise virtual, obtainable and available only by one single customer. Top advantages of this arrangements are excellent security and more control. This cloud computing model is not available at cost-effective rates as business will have to buy or lease as well as maintain all the required hardware, software etc.

Hybrid Cloud

As the name itself indicates, a hybrid cloud, it is a mixture of both private and public cloud computing solutions. A Hybrid cloud computing enables a business/enterprise to amplify their efficiencies, by making use of public cloud environment for non-sensitive activities and tasks at the same time utilizing a private arrangement for complex and important functions, businesses and organizations can make certain that their cloud computing arrangement is perfect without paying anything more than is needed.

Different Models of Cloud Computing

Basically there are 3 different models of Cloud computing, 1). Software as service (SAAS), 2). Platform as service (PAAS) and 3). Infrastructure as a service (IaaS).

PaaS (Platform as a Service)

Platform as a service known as PaaS is a type of Cloud computing that gives a stage and platform to enable web developers and coders to develop applications as well as service over the web. PaaS computing based services are hosted in the cloud environment and obtained by users just via their system using web browsers.

Infrastructure as a Service (IaaS)

IaaS referred to infrastructure and is the foundation of cloud computing solution. Instead of buying or renting space in a physically located data center, workers and other required things to maintain and administer computer servers, cloud computing networks and storage, cloud service customers lease space in the data center located virtually from an IaaS service provider. The customers will get access to the data center virtually through web. This type of computing model of cloud gives the raw materials for IT requirements and users just pay for the resources they actually use, which contains, Memory, RAM, CPU power/Cores, web space, hard disk, bandwidth etc. Only actual cloud service providers enable user to rent and lease virtual server along with storage whereas making systems to integrate them all. At the time leasing from a cloud IaaS service provider, users are simply leasing the hardware and required software/applications that automates it.

SaaS (Software as a Service)

SaaS referred to as on-demand software solution, SaaS is mainly a software licensing along with a delivery model in which a completely accessible and operational software is given to users via web on a subscription basis. Software as a Service solutions are mostly obtained by customers via a web browser on their system and can be charged based on the usage or sometime fixed month to month billing.
