What is Cloud Computing?
Cloud computing is a service that allows customers to work on the Internet. It explicitly declares that cloud computing means storing and accessing data and programs on the Internet instead of the computer's hard disk. Data can be anything like music, files, pictures, documents, and more.
User can access data from anywhere with the help of internet connection. To access cloud computing, the user must provide an ID and password for registration and security reasons. The transfer speed depends on various factors such as internet speed, server capacity and many more.
Cloud computing is managed by the host itself as they come with new modifications, which continuously improve service. The host has a sufficient amount of storage and fast processing servers, through which data is accessed very quickly. The major advantage of cloud computing is that the user can focus on the work, leaving only the problems behind.
History of Cloud Computing
Before cloud computing emerged, client/server computing was centralized storage in which server data, software applications, and all controls resided on the server-side.
If a user wants to run a program or access some specific data, he connects to the server and gets proper access and can do his business. The distributed computing concept followed, where all computers are networked together and resources are shared when needed.
The concept of cloud computing came into the picture in the year 1950 with the implementation of mainframe computers accessible through thin/static clients. Then in 1961, John McCarthy gave a speech at MIT, suggesting that computing could be sold as a utility like electricity and food. The idea was great but it was way ahead of its time and despite the interest in the model, the technology at the time was not ready for it.
In 1999, Salesforce.com became the first company to enter the cloud sector, promoting the concept of providing enterprise-level applications to end-users via the Internet. Then in 2002, Amazon came up with Amazon Web Services, which provides services such as computation, storage, and even human intelligence. In 2009, Google Apps and Microsoft's Windows Azure began providing cloud computing enterprise applications. Other companies such as HP and Oracle also joined the stream of cloud computing to meet the need for more data storage.
1. Cost-Effective
Cloud computing is economical because the user has many free opportunities when they start using it and after that, they only have to pay for basic services. Many reliable services are available for the use of the general public.
2. 24*7 Availability
Cloud service is available every time as all queries and issues are resolved with the help of technical support, which is provided through phone calls. Workers can get help from anywhere.
3. Security
Since the data is saved in many places, there is no loss of data. Cloud computing provides a high level of security because stored data is important and should not be lost. With remote access, data can be modified or deleted from anywhere. Even if the device is lost, the data can be modified or deleted from anywhere with the help of internet connection.
Cloud Computing Deployment Methods
There are four cloud computing deployment methods that vary according to need. The customer can choose which one suits them the most. In this session of Cloud Computing tutorial, we are going to mention all deployment methods:
Public Cloud
Community Cloud
1. Private Cloud
A specialized cloud company maintains the management, deployment and operation of the cloud. This cloud operation can be with the third party.
2. Community Cloud
Companies with similar interests and functions can share the same cloud and this can be done with the help of community cloud. The primary investment is saved, as the setup is installed.
3. Public Cloud
In Public Cloud, the company provides the infrastructure to the customer on a commercial basis. It helps the client to develop and deploy the application with minimum financial outlay.
4. Hybrid Cloud
In a hybrid cloud, moving applications from one cloud to another is easy. Hybrid cloud is a combination of a public and private cloud that supports the need to handle data in an organization.

Cloud Computing Companies
Most companies are using cloud computing and others are using cloud computing. Cloud computing is one of the important parts of a business and can benefit in many ways. There is a tremendous amount of data from day to day and the data needs to be stored, therefore, most companies require it. Some companies using cloud computing are:
Netflix
Pinterest
Xerox
Instagram
Apple
Google
Facebook
Cloud Computing Tutorial – Conclusion
Cloud computing is the major focus as companies are generating a lot of data which is to store for further analysis. Companies are increasingly coming up with servers so that service is faster and quicker access. With the help of cloud computing, the user can focus on different aspects of the company and help provide growth to the company.
