What is cloud computing and how it can be learned at very basic level?

“I do not need a hard drive in my computer if I can access the server faster… By comparison, carrying around an unconnected computer is a byzantine thing.”  rightly said by Steve Jobs, co-founder, CEO and chairman of Apple Inc.

The Basic Idea Of Cloud Computing

Cloud computing is the long-awaited realization of computing as a utility. The making of software today also influences the look of hardware. Be it design or purchase. Services no longer require large investments. Be it in hardware or in human resources. You have to deploy or run their service. You no longer have to worry about a service being oversized. What matters is that popularity meets expectations. If it does not, costly resources are wasted. All in all, they miss out on very important customers and revenue.

What Is It About?

Now let us take a look at a cloud. Cloud computing relies on virtualization and automation technologies. For example, virtualization enables services and underlying cloud systems. Automation and related orchestration capabilities provide users with a high degree of self-service. These technologies are about provisioning resources, connecting services and provisioning workloads. So, this is a place where everything gets done. Things get done without the need for cloud provider staff to intervene IT.

What Happens In a Cloud?

How does a cloud work? In the cloud, we can use technology services vicariously. You use it for purchasing, ownership and many other activities. The cloud is also used to manage physical data. The cloud environment provides an accessible online portal. They manage computing, storage, network and application resources.

A Cloud Is Always on Site!

Cloud computing offers an alternative to an on-site data center. In an on-site data center, we have to take care of everything. You plan the network setup. You take care of configuring the firewall and setting up the storage for the data.

From now on, a cloud provider takes care of purchasing and maintaining the hardware. They also offer a wide range of software and platforms as a service. We can also rent all these services. All we need are the cloud computing services, which are charged according to usage. After we have everything set up, we move on to the next step.

Types Of Providers:-

Cloud computing consists of applications and the hardware. They focus on the things that are provided as services over the internet. Also, the main focus is on the hardware and the system software in the data centers. Those that provide these services. The services themselves as software.

Some providers use terms like IaaS (infra-structure as a service) and PaaS (plat-form as a service). They use them to describe their products. But we avoid these terms because accepted definitions still vary. That’s because the line between a “simple” infrastructure and a higher-end “platform” is unclear. But we know that the two have more in common than they have differences. So, they need to be coordinated together.

IaaS:

The acronym stands for Infrastructure as a Service. It is a form of cloud computing that uses virtualized computing resources. These are then provided via the Internet. It is the basic layer of cloud computing. Here you can outsource various types of IT infrastructure.

PaaS:

Stands for Platform as a Service. It is a type of cloud computing model. Here, a third-party vendor provides software and hardware tools.

SaaS:

Stands for Software as a Service. In the SaaS model, the software is provided by cloud providers over the Internet. In the process, the applications are uploaded online.

Types Of Clouds:-

Cloud providers offer to many businesses. They are easy to scale, cost effective and easy to manage. Most servers like Google, Amazon and Microsoft are examples of public clouds. The hybrid cloud environment model is a combination of 2 things.

One is a private cloud environment model and the other is a public cloud environment model. The hybrid cloud model is one of the most scalable cloud models. They are flexible and cost-effective environments with enhanced security.

How To Learn From Scratch?

It’s just a matter of following these 5 basic steps. The understanding of this will give a better clarity to anyone thinking about exploring the options

Step One:

Basic knowledge of IT (no knowledge of cloud computing) is important. This includes understanding the basics of Windows and Linux. You should also know the basics of networking and how operating systems work.

Step Two:

You need to master cloud and virtualization concepts! Do what is outlined in the prerequisite for cloud computing. All you need is an understanding of the concept of virtualization.

Step Three:

Learn the basics of cloud computing. You need to start with the basics. There are numerous courses available online to learn the basic of cloud computing. Though it has been hyped since the dawn of the cloud computing era, almost everyone is talking about private clouds. They have limited access to internal teams. The hybrid cloud environment model is a combination of 2 things

Step Four:

It’s important to learn Linux and networking. In your initial approach to cloud computing, the Linux operating system plays a key role. Learning Linux can help developers or system administrators in their work.

Step Five:

Amazon Web Services or Google Cloud Platform AWS are some growing platforms. There are many courses on it as some companies. They are starting to consider them for different workloads or for migration. If you gain a better understanding of Amazon Web Services, you have an advantage. You can build on your existing skills. AWS career through continuing education courses.
