Cloud Computing – What Is It And How Does It Work?

Cloud Computing

Ask any business about its current computing structure and the “cloud” will be the unanimous response. Yes, cloud computing is fast becoming the order of the day in contemporary internet-connected times. So, cloud computing what is it and how does it work? Well, the post below explains the basics of cloud computing followed by its operational structure.

What is Cloud Computing?

Let’s start with the basics of cloud computing first. Well, before proceeding any further, you should know the word “cloud” here refers to the Internet. Cloud computing defines a system where you get the on-demand facility of database storage & sharing, computer power, an operation of applications as well as other different IT resources via the Internet. It’s the cloud provider who owns and manages the network hardware for cloud computing.

When you adopt cloud computing, most of the computing works will be carried by the cloud system. It eventually means less involvement of your on-premise hardware and software. You will just need to install the cloud interface software in your system and it will take care of all your computing, storage and data backup needs.

One of the most common applications of cloud computing that we all use today is a web-based electronic mail service. When you create your account on a web-based electronic mail service- your account & mail data are stored independently of the computer used to create the account.

The account data stay on the cloud network or the Internet which makes it possible to access it from any browsing device anytime.

How does Cloud Computing work?

The operation of a cloud computing system can be broadly divided into two parts- front end & back end. Both the sections are connected to one another via the internet.

So, what is a front end? Well, it refers to the part of computer user- precisely you, the cloud client. It involves your on-premise computer network as well as the very application through which you can access cloud computing.

And what is the back end? This part refers to the “cloud” part of the cloud computing system. This section embodies different servers, computers as well as data storage bases that altogether make up the “cloud”.

The whole system of cloud computing is governed by one central server which also monitors traffic as well as client demands. The central server abides by a list of protocols and deploys a special software program called “middleware”. It’s this special software program that enables easy communication between the networked computers on the cloud. What you get, essentially, is the ability to securely store and access your data from any device.

Types of Cloud Computing

Cloud computing can be divided in two ways- in regards to the deployment model and in regards to the service model.

Types in regards to the deployment model

There are 3 major types of cloud computing under this section –

Public cloud: When you go for a public cloud, the entire cloud infrastructure will be set on the cloud provider’s premise. You will have to share the network, hardware and storage with “cloud-tenants” (read other users) on the same setup. Besides, the cloud provider will manage and control your entire cloud computing framework.

Private cloud: It’s different from the public option in the sense that here the cloud computing will be set on your on-site data center. You will get a dedicated network exclusively for your cloud account and everything here will be managed by your team. Such a setup offers you the flexibility to customize the resources in tune with your specific IT requirements. A private cloud setup is especially important when you want to complete the confidentiality of your crucial business data.

Hybrid cloud: if you want the best of both public and private cloud, look no further than the hybrid cloud. It offers you amazing flexibility to move your data or applications easily between the other two cloud systems- as per your typical business needs. For example, you can use a public cloud when you want to use web-based email services. Similarly, you can fast migrate to the private cloud structure when you have to deal with confidential business files.

Types in regards to a service model

IaaS (Infrastructure as a Service) – It comprises the basic foundation of cloud IT systems and extends easy access to computers, networking features & data storage base. With IaaS, you will get the highest possible flexibility and control on your business IT resources compared to the other two types.

PaaS (Platform as a Service)- It relieves the cloud user from the burden of managing the cloud hardware & operating systems. This way, you get more room to work on the deployment as well as management of applications for your business. You will no longer need to brainstorm on software maintenance, resource procurement, patching, capacity planning and all heavy works related to running the business applications.

SaaS (Software as a Service)- With SaaS cloud model, a user gets a complete product which is operated and managed by his cloud service provider. In this case, you won’t have to bother about the maintenance of the service nor you need to worry about the management of the underlying cloud infrastructure. Your only focus would be on how to use that specific service software. You can learn more about it here.

Final Words

Cloud computing is no less than a boon for businesses in modern digital times. One of the best advantages of cloud computing is the ability to access your data from anywhere and anytime. You will just need a solid Internet connection and a browsing device. It eventually allows for better workplace collaboration and flexibility. For example, say, you are working with remote employees on a specific project.

If your business files and applications are on a cloud, everybody involved in the project can access them from their own browsing devices only. No longer would you have to meet physically to access and share the resources needed to work on the project.

Cloud computing also assures better security for your data. When you store your data and files on the cloud, your resources will be safe even if your office desktop faces a crash or damage. A cloud infrastructure will keep your data guarded against any kind of accident or natural disaster in your workplace.
