Understanding “The Cloud” and Cloud Computing

Hello Folks, Welcome back to Learnizo Global. Have you ever wondered how you could find all your photos, videos, and conversation history on Instagram, Whatsapp, or Facebook when you log in to your account from a new device? This is because your information is stored in “the Cloud” that can be accessed from any device through an internet connection. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive. The cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. Cloud and cloud computing is far more capable of providing shared resources and services to business organizations as new agile and advanced technologies are emerging. This article will give you an insight on Cloud and Cloud Computing from the business perspective. Later in the article, we shall also discuss the advantages of cloud computing.

What is a Cloud?

The cloud enables anyone with an internet connection to access IT resources on-demand, such as those consumed by cloud-based applications. The basic resources available compute, storage, and networking, all of which are needed for a business-critical application to deliver a full experience.

“The cloud” refers to servers that are accessed over the Internet and the applications and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don’t have to manage physical servers themselves or run software applications on their own machines.

Why is it called ‘The Cloud’?

“The Cloud” started off as a tech industry slang term. In the early days of the Internet, technical diagrams often represented the servers and networking infrastructure that make up the Internet as a cloud. As more computing processes moved to this servers-and-infrastructure part of the Internet, people began to talk about moving to “the cloud” as a shorthand way of expressing where the computing processes were taking place. Today, “the cloud” is a widely accepted term for this style of computing.

For businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact for small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.

Cloud Computing Overview

Cloud computing is possible because of a technology called virtualization. Virtualization allows for the creation of a simulated, digital-only “virtual” computer that behaves as if it were a physical computer with its own hardware. The technical term for such a computer is a virtual machine (VM). When properly implemented, virtual machines on the same host machine are sandboxed from one another, so they don’t interact with each other at all, and the files and applications from one virtual machine aren’t visible to the other virtual machines even though they’re on the same physical machine.

Virtual machines also make more efficient use of the hardware hosting them. By running many virtual machines at once, one server becomes many servers, and a data center becomes a whole host of data centers, able to serve many organizations. Thus, cloud providers can offer the use of their servers to far more customers at once than they would be able to otherwise, and they can do so at a low cost.

Even if individual servers go down, cloud servers, in general, should be always online and always available. Cloud vendors generally back up their services on multiple machines and across multiple regions.

Users access cloud services either through a browser or through an app, connecting to the cloud over the Internet – that is, through many interconnected networks – regardless of what device they’re using.

Advantages of Cloud Computing

Cost Shift

The financial challenge for any business organization of an on-premises infrastructure is the CAPEX (Capital Expenditure) that goes into creating, fixing, and updating the hardware in it, often involving substantial over-provisioning of resources. This is in addition to the OPEX (Operational Expenditure) of energy bills and paying personnel to operate and monitor the infrastructure.

Using the cloud reduces the CAPEX costs, replacing them with OPEX costs as part of the service subscription. This means that costs better reflect actual infrastructure use and infrastructure upgrade costs can be more easily absorbed into operating budgets.

Scalability

When a company is subscribed to a cloud service, it can easily scale resources up and down as needed.

Resource Management

Cloud computing and networking allow companies to improve resource management from infrastructure to personal. Resources can be procured, paid for, and used with greater specificity. Monitoring tools allow organizations to watch resource use and adjust their usage so they aren’t paying for unused resources.
