Cloud Computing

Cloud computing is the on-demand availability of computer system resources, uniquely data storage and computing power, without uninterrupted active management by the user. The phrase is ordinarily used to describe data centres available to many users over the Internet. It is the use of hardware and software to fulfil a service over a network. With cloud computing, users can access files and use applications of any device that can access the Internet.

The “cloud” is a set of different types of hardware and software that work collectively to utter many aspects of computing to the end-user as an online service.

An illustration of a Cloud Computing provider is Google’s Gmail. Gmail users can obtain files and applications entertained by Google via the internet from any device.

How is computing from the Cloud offbeat from computing from my hard drive of PC?

Unlike conventional computing where data is stored on your PC’s local hard drive, the data in the cloud is saved on many physical or virtual servers that are hosted by a third-party service provider. An instance of a cloud computing file storage provider is Dropbox. Dropbox files can be reached from any device via the Internet.

What is the basic disparity between cloud computing and cloud storage?

When you’re saving your photos, music, movies, or any other kind of data online rather than using your physical store to do so, you’re storing your data on the cloud. Applications like iCloud, Google Drive, Dropbox are all examples of cloud storage.

When you’re using online services to accomplish specific tasks where the resources of other computers are appropriated it could be performing a Google search, Net banking you’re using cloud-based services to complete your tasks.

Are your files safe in the Cloud?

While no storage solution is 100% safe, cloud storage providers can advance a safer and more convenient place for companies to store data than conventional computing methods.

Depending on the service commitment, duplicate copies of the company’s data can be stored on servers stationed in different geographies and preserved by backup power accumulations in the case of a disaster.

Today, numerous companies are moving to a Hybrid Cloud Computing model. With this model, companies are given the versatility of saving delicate data securely in a private cloud while storing public data in a public cloud. Both foundations are kept as separate, unique items.

Common Cloud Service Models

Cloud services are typically deployed based on end-user requirements. The primary services include the following:

Software as a Service (SaaS):

SaaS is a  software delivery order that provides access to software and its functions remotely as a Web-based service. Instead of spending an upfront fee to buy and/or license software, SaaS customers spend a recurring fee to subscribe to the service. In common, they can access the SaaS from any Internet-connected device, any time day or night. Well-known examples of SaaS introduce, Microsoft Office 365, Google G Suite, Dropbox, Adobe Creative Cloud, and others.

Platform as a Service (PaaS):

PaaS is a computing platform implying delivered as a service. Here the platform is outsourced in place of a company or data centre buying and controlling its hardware and software layers. Most places are designed for developers and aim to simplify the process of creating and deploying software. For example, a Web developer might use a PaaS that includes operating system software, Web server software, a database, and related Web development tools. The foremost PaaS vendors include Amazon Web Services, Microsoft Azure, IBM, and Google Cloud Platform.

Infrastructure as a Service (IaaS):

Computer infrastructure, such as servers, storage, and networking addressed as a service. IaaS is familiar with enterprises that relish the convenience of having the cloud vendor manage their IT infrastructure. They also sometimes see cost savings as a result of funding only for the computing resources they use. The leading IaaS vendors include Amazon Web Services, Microsoft Azure, IBM, and Google Cloud Platform.


While SaaS, PaaS, and IaaS are the three most common types of cloud services, cloud computing vendors sometimes also use other “as a service” labels to describe their offerings. For example, some offer database as a service (DBaaS), mobile backend as a service (MBaaS), functions as a service (FaaS) or others.

Cloud computing is a new technological advancement that has the potential to have a vast impact on the world. It has many gains that it provides to its users and enterprises. For example, some of the benefits that it provides to businesses are that it reduces operating costs by spending less on maintenance and software ascents and focus more on the businesses itself. But there are other hurdles the cloud computing must surmount. People are very suspicious about whether their data is protected and private. There are no criteria or regulations worldwide that provided data through cloud computing. Europe has data assurance laws but the US, being one of the most technologically superior nations, does not have any data protection laws. Users also fret about who can reveal their data and have ownership of their data. But once, there are standards and regulations worldwide, cloud computing will remodel the future.
