When viewed from the system usage or access rights, cloud computing is divided into four types. The following is an explanation.

1. Public cloud

Public cloud computing is the storage of any data and information on internet media with a service model that uses public access rights. This means you can use every feature and service for free and do not require a fee.

An example of public cloud computing itself is social media, such as Facebook, Twitter, Instagram, Youtube, and others. Then, on email-based services are Gmail, Yahoo, and Hotmail. However, the public cloud also has weaknesses, namely a security system that is easily hacked and takes the user’s personal data for sale.

2. Private cloud

Private cloud is the use of cloud technology for the benefit of an organization or company that is private. Usually, it is used for business needs to make it easier and faster to connect communication between teams.

For its own application, it can only be used by stakeholders in the same company or organization. Therefore, private cloud computing has a better security system than public cloud computing.

3. Community cloud

A community cloud is a cloud-based storage system that is used for the benefit of a community or institution. Community cloud can be managed internally or using the help of third parties so as to minimize costs incurred and can be borne by both parties.

4. Hybrid cloud

A hybrid cloud is a combination of private and public cloud computing, where this service is usually applied to an institution. This service is also included in Business to Business (B2B) and Business to Consumer (B2C).

Cloud computing structure

Next, enter the discussion material about what structures are owned by cloud computing.

1. Computer front end

The front-end computer is a desktop computer that appears on the front page of the interface. Which, in this case, is the side of the client and the cloud computing system. Which will then be adjusted according to the functional requirements of each interface.

2. Computer back end

A computer back end is a computer to serve the needs of large amounts of data storage, for example, a server computer and a data center. Typically, the computer back end takes care of the performance and high capacity database management needs.

3. Computer front and back end (Hybrid)

This third structure serves to connect the two computers above. Where it is possible to exchange information and data quickly and accurately, examples of this device are LAN (Local Area Network) and the Internet.

How cloud computing works

Cloud computing technology itself makes the internet a central server in managing data. The system makes it very easy for users to register and enter the application without the need to install it first.

Because it does not require an installation process, the storage is done virtually. So as not to overload memory usage on client computing devices. Then, you can run various commands on the interface display menu, and the application server will then process it.

The following are some of the benefits of cloud computing, including the following.

1. As a storage medium on the server centrally

The first benefit is being a storage place for various information in the form of documents or data in a systemized and centralized manner. You only need to use one server application, and you don’t need an installation process.

2. As a data security center

The second benefit is that cloud computing provides much better security features than conventional storage models because the data security center is managed directly by a giant company that has complex big data and resources.

3. Durable and does not require high costs

The last benefit is that it does not require a large fee because a lot of cloud computing access is free and does not incur additional costs. An example is the use of social media and email management applications.

Conclusion

• Cloud computing is a data computation processing process with the help of internet networks to store large-scale information needs.
• Types of cloud computing are divided into four, namely private, public, community, and hybrid cloud.
• The structure of cloud computing is divided into three main parts: computer back end, front end, and hybrid.
