In cloud computing, the term cloud is used as a means for the Internet, in which there is a network of large groups of remote servers that deliver servers, storage, and server services to the organization on the computer and devices through the Internet. Does.
Here Information is stored on physical servers who are used to maintain and control by cloud computing provider In cloud storage, you do not need to store information on your own hard drive.
Instead, it is stored in cloud storage, and you can access it from any location and download it on any of your favorite devices like laptops, tablets, or smartphones.
In addition to this, to postpone the work away from the office, you can edit files of Word documents or PowerPoint presentations with other users.
Cloud Computing has become a highly sought after service due to the availability of high computing power, low-cost services, high performance, scalable, accessibility along with availability.
According to recent research, there are approximately 1024 pet bytes data on cloud computing, or some say it's 1,07,30,741,824 GB or we can say that there are really huge data.
How Cloud Computing Works?
Cloud computing works on the physical server through the Information and Software Store. These servers are controlled by the provider.
To understand how cloud computing works, imagine that there are two layers in the cloud - backend layers and front-end layers. Front-end layer is what you can see and interact with it.
When you access Gmail like Webmail, it is possible due to the software running on the cloud's front end layer. These are applicable to your Facebook account. Architectures of hardware and software in back-end help to see the front end.
Cloud Services:
Cloud sewers are usually divided into three types:
1) Infrastructure-as-a-service (IaaS):
It gives access to Services on Demand IT Infrastructure. It includes storage, network, and a computer that runs your workload. As a business user, you can request IT Services, and pay only the services you are using.
2) Platform-as-a-service (PaaS):
Platform-as-a-service (PaaS) This is a cloud base environment, which you use to develop, test, run and manage your application. This service includes web servers, Dev Tools, Execution Runtime and online database. Its approach is to give development environments according to your need, without the complexity of purchasing, creating or managing basic infrastructure. As a result, you can work fast and release the application quickly.
For example, you have developed your own e-commerce website, but a shopping cart, checkout and payment mechanism are running on all Merchant's servers.
3) Software-as-a-service (SaaS):
SaaS is the most common form used by small businesses and includes the use of host software on a remote server. It runs applications through your web browser and stores, retrieves or shares store files outside of your business.
Web-based email, office software, online games, customer relationship management systems and communication tools are all examples of SaaS.
4) Charges For Cloud Computing:
According to your needs, the price of Cloud Services is different. 5-10GB of free space is available for personal use. If you need additional storage, you will have to pay for it.
Advantages Of Cloud Computing
1) Worldwide Access:
You can stay anywhere in the world, use it. Cloud computing increases mobility because now you can access your documents from any device in any part of the world.
This is even more beneficial for business, employees can take documents without them, do their work at home or on business trips. It increases productivity and provides a faster exchange of information.
2) More Storage:
In the past, the memory was always limited to a particular device. Cloud computing has increased the storage so you will not have to worry about the end of the store on the hard drive now.
3) Easy Set-Up:
You can set up one-minute cloud computing services. For this, it is easy to adjust your personal settings, select a password, or select which device to connect to on the network.
4) Reduced Cost:
Cloud computing is often cheaper. If the software is already installed online, you will not need to reinstall it on your own PC. Many cloud computing, such as Dropbox, allow Google Drive to free up to 10 to 15GB of space storage.
If you pay for cloud services, then it is on a monthly or annual basis. In this, you only pay for the services you need.
Disadvantages Of Cloud Computing
1) Security:
When using a cloud computing service, you are essentially handing over your data to a third party. The fact is, these servers are accessing many users simultaneously in the world, then security issues are there.
The company has confidential information, and they can always be especially worried because their data can possibly be harmed by viruses and other malware. However, some servers are using spam filters, email encryption, and secure HTTPS.
2) Privacy:
Cloud computing comes with the risk that unauthorized users can access your information. To prevent this from occurring, cloud computing services provide password protection and work on secure servers with data encryption technology
3) Loss of Control:
Cloud Computing Services controls the user. It not only determines how much you will pay to use this service but with this, you can store which information you can store and decide from where you can access it.
4) Internet:
While Internet usage is increasing rapidly, but it is still not available everywhere. If you are in a location where there is no access to the Internet, then you can not use the cloud services. Cloud Computing
