What is Cloud Computing – An Introduction

Everybody seems to be talking about cloud computing and the phraseology has become an industry’s buzz word. But with so many explanations of the term flying around, many might be hard pressed to define the term cloud computing. When you pool together certain computing resources and services and then deliver them over the World Wide Web, you get the term cloud computing. This name has been derived from the relationship depiction between all the aspects of computing that represent the Internet, that are usually resembled in the form of a cloud.

What is Cloud Computing

Classifications of Cloud Computing

When you deliver computing as a service instead of as a product and provide to computers and other instruments such things as shared resources, information and software over a network generally the Internet, you are engaging in cloud computing. Any hosted service that is delivered over the Internet is known as cloud computing. Such services can mainly be broken down into three classifications i.e. Infrastructure-as-a-Service (Iaas), Platform-as-a-Service (Paas) and Software-as-a-Service (SaaS).
Features that Distinct Cloud Computing from Normal Hosting

Although the term hosted service is used in cloud computing, there are three very unique and outstanding typical features or traits that individuate cloud computing from the usual established hosting. First is that cloud computing is always being sold on demand and generally by the minute or the hour. Secondly, cloud computing is very extendible, extensible and flexible and its consumers can access as much or as little as they desire at any point in time. Thirdly, it is the provider who fully manages and controls cloud computing services and all the consumer needs is a computer terminal that has access to the Interment.

Public, Private and Virtual Private Cloud Computing

You can find public cloud computing as well as private cloud computing. With public cloud computing selling their services to anyone on the Internet while private cloud computing services serving as a propriety network or data center that provides hosted services to a select number of people. There is also another type of cloud computing that is know as a virtual private cloud and is a result of a service provider using public cloud resources to generate their private cloud. Regardless of whether cloud computing is public, private or virtual; it is designed to give effortless and expandable access to functions of computing and IT.

What is Cloud Computing for Consumers

The interplay between an assortment of virtualized supplies whereby cloud servers link and appropriate information depending on the website traffic across the whole network is what cloud computing is all about. The advantage that cloud computing offers to its consumers is that they don’t have to invest in, manage or maintain any tangible framework that is necessary for the administration of extreme vacillation and influx in traffic. All the need to do is pay for the resources that they use, if and when they need to use them. This makes them free to enthusiastically and instinctively or impulsively popularize and advance their websites and attempts at the manipulation of peak traffic is no longer a worry for them.

Understanding Different Types of Cloud Computing

While the IT world has witnessed a significant growth in cloud computing, there is still no consensus as to a common understanding of cloud computing and this is something that has continued to develop progressively. There is a continuous need to make clear the wording and the abstractions that are used for the description of cloud computing.

There has not been much that has been done in the way of analyzing the typical features, the setup and the services that comprise what cloud computing is or what it can be. While we can summarize cloud computing allowing for the sharing and scalable deployment of services, as needed, from almost any location, and for which the customer can be billed based on actual usage.

Classifications of Cloud Computing

What cloud computing does is that it offers different ways for businesses to expand their IT proportions or operations without having to invest in any more infrastructure, personnel and software. Once we have established what cloud computing does, we will be able to understand the different types of cloud computing services in terms of business modules. These can be distinct from each other depending on the necessity of services provided. The following are the six distinct classifications of cloud computing and what they present businesses with.

Web Based Cloud Services

Web based cloud services give businesses the opportunity to take advantage of operations of web services instead of using completely established functions. This for example might include an API for Google Maps or for a service such as one involving payroll or credit card processing.

SaaS (Software as a Service)

This involves the provision of a specific application to diverse tenants who generally use the browser. Saas solutions are in most cases used in sales, and human resource (HR) and enterprise resource planning (ERP).

Platform as a Service

This service is a variant of SaaS and while you may be able to operate your own application, you will be doing it on the cloud provider’s infrastructure.

Utility Cloud Services

These are virtual storage and server alternatives that businesses and organizations can use on demand and also have the provision for the businesses and organizations to create a virtual data center.

Managed Services Platforms

Managed services are probably one of the oldest emphases on cloud solutions. Through these services, the provider of cloud services uses applications instead of end users which might include anti-spam services or maybe application monitoring services.

Service Commerce Platforms

This is the combination of Software as a Service (SaaS) and Managed Services Platform (MSP) and provides people with a place where they can go to for interactions. This kind of computing is generally used through trading environments as a hub of services where the end user interacts. Common applications will include expense tracking, travel ordering, or even virtual assistant services.

While the above six classifications of cloud computing have been identified, this is simply the beginning. As discussed above, cloud computing is continually emergent and innovation continues to bring about new ideas into prominence. With cloud computing becoming a more functional and essential alternative for many businesses, there is a likelihood of many more categories coming into the picture.

Summary of Cloud Computing

Cloud computing is really distributed computing whereby a function is created using resource from diverse services possibly from different locations. It is also the accessing of computing and IT services that are required for the performance of functions that have needs and that are always vigorously alternating.
