Cloud Computing

In simple terms, cloud computing means storing data and accessing data and programs over the internet. Think like I have some X company and I’m going to build a website for my company think like an enterprise application so It needs to be accessible to everyone throughout the world then I have to deploy my application in somewhere else so that it will be available to everyone in olden days for accessing my web application I need to build huge hardware so that It will be accessible to everyone and I have to save data of my users if I have a large infrastructure and I can store the data mean that end users data here I need to arrange the infrastructure mean that memory, processor, Disks, and network facility and I have to buy all these infrastructures and arrange them properly with all attachments that are required to work and they build in a form of racks or proper order think like that now or all these assembled at one place here hardware will be computer hardware mean that processor, memory and network, hardware.
In simple words think like cables mean networking and storage means that disks at past all these things will be maintained by the organizations, and they maintain the data. While building all these infrastructures it is difficult to maintain and to maintain this infrastructure, they need to be technically strong so that they can maintain their data centers and they deploy their applications in their data centers mean that they build and deploy applications in their data centers and end users are able to access.
Technically all these data centers mean that Infrastructure is built by these organizations that are now moving to the cloud and hosted somewhere else in a different location through the internet we are going to access them this is cloud computing is the provision of computer services over the internet that services Compute, Networking, Storage, and the Internet enable us to gain access here, which is flexible and simple….
All these services will be delivered by the service provider.
- Microsoft Azure
- Amazon AWS
- Google GCP
In this section, I’d like to highlight Azure resources.
ACCOUNTS FOR STORAGE
VIRTUAL NETWORKS
APP SERVICES
SQL DATABASES
FUNCTIONS

Each computer has hardware that is top on its Operating System and top on its application. Currently, I’m using Windows as my operating system. I’m thinking of working with Linux or Mac OS Unix. Therefore, I must buy a new system and I must work on that.
Here buying a new machine and I have to pay money for that if I want to work in that environment but here the cost is higher hypervisor is a technology that helps us to create multiple virtual machines means that here we are able to install Linux environment in our host OS with the help of Virtual Box this is a software that helps us to install virtual machines and while Installing these virtual machines it utilizes existing hardware which exists is host Operating System think like I have a physical machine in that I have 8GB ram and CPU processor but now I’m on a thought to work with Linux Environment here I don’t want separate physical machines but I can install Linux software with the help of hypervisor while installing that software in our machines it takes existing hardware to think like it will take 4 GB ram ,CPU ,and Storage which exists in my host operating system and I can easily work on that environment but this is a type2 Hypervisor but type 1 is same like type 2 here we won’t use existing Operating System but we’re directly install hypervisor technology on hardware so this is a bit change between type 1 and type 2 hypervisor technology if you think why virtual machines are crated and deployed at same place what is the use if you ask me in this way then the my answer is that these are easy to handle , easy to create , reduces workload , her we get enough space ,and recovery. If you ask me why I use Virtual Box, I’ll say it’s because it’s free and comes from Oracle.
At last, I would like to mention the Virtual machine benefits.
- Accessibility
- Flexibility
- easy to use
- Recovery of Data
- To run various applications on different operating systems
- To learn various OS environments like Mac OS Unix Operating system or Linux or Windows
