What Is Cloud Computing? A Simple Guide for Beginners
Benefits of What Is Cloud Computing
A few years ago, if an organization wanted to run their software or store their data, they had to purchase a piece of hardware, install it somewhere in a room and get it maintained. The drawback of such practice was heavy expenses, constant maintenance, and huge amount of unused capacity all the time. With the advent of cloud computing, everything changed. Now the only thing that is needed to run some software is not to purchase and install it but to subscribe for the service online and pay for it based on usage.
In simple words, cloud computing is renting computing capacity, applications and storage from another person who hosts them in their data center. It does not matter where you are located and what type of the computer you have because everything can be accessed via internet. It means no need to install something on your PC and no worries regarding lack of storage space.
What is the Process of Cloud Computing?
In reality, cloud providers use massive data centers packed with thousands of servers. Those servers are split into pieces, and shared by millions of users with the help of virtualization technology, that allows one computer to work like multiple computers. That’s how the cloud became so scalable – resources can be assigned, increased or decreased according to the need. In case the visitors of your website increase drastically, the cloud will automatically allocate resources for them, and reduce once traffic becomes stable.
Types of Cloud Computing Services
There are three main types of cloud services:
To better understand What Is Cloud Computing, it’s important to know the three main cloud service models.
IaaS stands for Infrastructure as a Service and includes the provision of computing infrastructure such as servers, storage, and networking, without you having to deal with physical hardware yourself. The operating system and applications, however, are still controlled by you.Further, Platform as a Service (PaaS) provides a pre-built platform for developing and delivering applications, eliminating any worries about server management and infrastructure. All developers have to do is concentrate on coding.
Software as a Service (SaaS) is an application that many people come into contact with every day without even knowing. Gmail, Dropbox, or Zoom are some examples of Software as a Service, which are delivered through the cloud to users’ browsers or apps without requiring any kind of installation.
The Various Deployment Models
Cloud computing services can also be deployed in various modes. A public cloud service represents the sharing of infrastructure facilities among a number of clients through a third-party provider. A private cloud is one in which a company has dedicated cloud-based services for its own use and has more control over them than in a public cloud. Another common deployment method used by many businesses is the hybrid cloud model, which offers a combination of private and public clouds.
Reasons Why People and Companies Are Turning to Cloud Computing
There are several benefits of cloud computing that make it attractive. The first one is obvious – financial. This type of computer system allows you to save money due to its pay-as-you-go pricing model, which means that you do not need to invest heavily in hardware in advance. The second benefit is scalability. You can add or reduce your computing resources right away. Thirdly, you can access your information and programs wherever you are thanks to the internet.
Reliability and security are two other factors why cloud computing is beneficial for companies and people. As cloud computing providers spend plenty of money on the protection of their networks and their customers’ data, users do not need to create a reliable and safe network themselves, as they often cannot. Moreover, they do not need to install any updates or replace their old hardware.
Several Issues To Consider
There is one important aspect that must be taken into account when it comes to cloud computing. Your data is stored somewhere else, so the security policy of your service provider is extremely important.
The internet connection also becomes critical — without it, one will not be able to use the services provided by cloud solutions. And although the total expenses could be less, it can still occur that the unexpected billing comes if there is a sudden change in consumption of the cloud resources.
What Is Cloud Computing is one of the most important technologies today. Learning What Is Cloud Computing can help students and professionals build successful careers in IT.
Cloud computing has revolutionized how people and organizations approach technology. Gone are the days when people used expensive physical components of hardware. Now, the cloud computing helps stream videos, upload photos, or provide all IT facilities for companies. So no matter what you do or what you use, most probably, it has to do something with the cloud computing.
