What is Cloud Computing and how does Cloud works?

Hey Folks,

As you know and have listened to cloud computing words nowadays often, but what do you actually mean by the terms Cloud? Is it a real cloud carrying our Servers? or some wireless networking that connects us to that moving cloud, only data storage? or google drive is all that cloud is..!

What is Cloud..!

Well, hold on to your breath..!

These all are common questions that usually strike very first when we listen to the term Cloud!

This blog will clear all your doubts about Cloud Computing and make it very simple for readers to understand. Moreover, we will talk about how cloud computing will take over our in-house Servers, cloud security points, and the Pros and Cons of Cloud Computing in the Era where Machine rules over the Next-Gen.

Ques. What do you mean by Cloud Computing?

Ans: First you need to understand how an in-house server works..!

Client-Server

Okay, So what is the Internet? The Internet consists of two major words Inter + Net which elaborates into Inter + Networking, which means interconnected systems through some network (wired + wireless).

So now coming on to the point what are Server and Client?

When some System makes some requests to other systems having Data, the System that is requesting is known as the Client System and the System that is Responding is known as Server System. In this scenario, anyone can be the server and the client depending on who is Requesting and who is Responding.
Server - System where your application is stored and when requested by the client system it uses its Processing power and Memory and Responds to the Request.
Client - The System that is willing to use the Application stored in the Server to get the data, application, etc.. by a request.

So you know now how all application works in-house, but here the issue is maintaining the server hardware, Manpower for its Maintenance, server costing, a place to keep servers, and many more headaches.

Here comes the concept of Cloud Computing...

Cloud Computing:

The word "cloud" is used as a metaphor for "Internet" so the phrase cloud computing means a type of Internet-based computing.

Where different services including servers, storage, and applications are delivered to an organization's computers and devices through the Internet.

Working of Cloud

Servers are kept in a remote location where you are given an IP address to connect the server and deploy your application remotely.
You just need to Pay-As-You-Go mean only pay for the resource and time you buy the server.
Scalability over Hardware to increase and Decrease on demand.
Provides your Data Security Invulnerability and Scalability.
Can store your static Data at the cheapest rate.
Accessible anywhere in the world with any device having Internet connectivity.
Focus on your core product item rather than involving Hardware maintenance and buying stuff.
Space-free hardware over the Internet.

Cloud vs In-House

Cloud Computing:

Pros:

No need for onsite hardware or capital expenses. Well-suited to smaller companies that may outgrow storage too quickly.
Storage can be added as needed. Solutions are often on-demand, so you only pay for what you need.
Backup and restore can be initiated from anywhere, using any computer, tablet, or smartphone.
Data can be backed up in the cloud as regularly as 15-minute intervals, minimizing data losses in disaster situations. Small data set recovery time is improved.

Cons:

The data recovery costs could outweigh the benefits for companies that are not as dependent on uptime and instant recovery.
An organization may have a limit to data that can be stored in the cloud due to storage availability and cost.
If the Internet goes down on your side or on your cloud provider’s side, you won’t have access to any of your information.
Full data recovery could prove very time-consuming and impactful on systems. However, if a Datto is used, recovery can occur in minutes.

In-House:

Pros:

It gives you physical control over your backup.
Keeps critical data in-house. No third party has access to your information.
No need to rely on an Internet connection for access to data.
It can be more cost effective for small to mid-sized companies.

Cons:

Requires a capital investment in hardware and infrastructure.
Needs space in your office for a rack or server room/closet, in addition to dedicated IT support.
May be more susceptible to data loss during disaster situations due to its in-house location. How often you take the data offsite will reflect how much data you’ll lose in an emergency.
No uptime or recovery time guarantees.
