Difference Between Private Cloud, Public Cloud, and Hybrid Cloud From Cloud Computing | Terkreatif

For ordinary people who do not understand the term IT, they may rarely hear the terms public cloud, private cloud, and hybrid cloud. However, these three cloud computing services are very useful for our business and daily life. Cloud technology or better known as cloud technology has increased very rapidly, as evidenced by more and more companies or organizations starting to look at using cloud infrastructure to increase business productivity.

Cloud technology is developing day by day, ranging from cloud storage, cloud services to cloud computing. Do you know what services are available in cloud computing and what are the advantages of each service? Let's just find out below. Before going deeper, you need to know the meaning of cloud computing?

Understanding Cloud Computing

Cloud computing is a flexible network access model that is able to access resources into a pool that has been provided anytime, anywhere and most importantly the service has added value. These resources can be in the form of networks, services, applications, or storage.

Cloud computing or cloud computing includes various classifications, types, and architectural models. Transformative network computing models can be categorized into three main types, such as Public cloud, Private cloud, and Hybrid cloud.

Private Cloud

Private cloud is usually used by a company/organization that has high data confidentiality such as banking or government. Private cloud resources are isolated and delivered over a secure private network and are not shared with other customers. What's unique about private cloud is that it can easily meet business and security needs on demand from companies/organizations. examples of private cloud services are SaaS, PaaS and IaaS.

Advantages of Using a Private Cloud:

1. High-Security and Privacy
Private cloud services are private and not publicly available and resources are shared from different resource pools. 

2. Maintenance is easier
In terms of price, it is more expensive than public cloud, but private cloud is more efficient in terms of service maintenance, it is very easy to track and repair in case of trouble due to private service system. Private Cloud is easier to increase the capacity of hardware resources such as SSD, Memory.

3. Full control or full control
A private cloud has full control over its resources and hardware compared to a public cloud because it is only accessed within the organization

Public Cloud

For some industries, such as governments, banks, and research centers that are sensitive to data confidentiality, they will think about using a public cloud that cannot meet industry needs or external rules regarding data assurance.

Because this public cloud can be used by anyone, it is often intended for the general public who have a business and need a large cloud storage without thinking about data sensitivity. Therefore, you must also understand the risks before using this public cloud. However, if your company is not engaged in services or data privacy is not a problem for you, then this public cloud is enough to serve as a solution.

The main advantage of the Public Cloud is the ability to handle the specific needs of customers. This allows customers to get more hardware customization, data protection, and integration with external services.

Advantages of Using Public Cloud:

1. Lower cost
Users do not need to provide hardware or software to handle every customer need, the fees are paid according to your usage. And users don't need to spend a lot of money to buy a hard drive with limited storage with a public cloud, everything is there and costs are cheaper.

2. High Scalability
Cloud resources are available on request from the resource pool, can be upgraded or downgraded according to the needs of the user.

3. Reliability
Public Cloud uses a large number of resources from different locations. Because if one resource fails, the Public Cloud can use other resources.

4. Flexibility
Public Cloud can be integrated with other public cloud.

Hybrid Cloud

Hybrid cloud is a cloud computing service that integrates both private and public clouds to provide multiple functions within the same organization or company. If the private cloud offers sensitive operation services and the public cloud offers the convenience of a publicly accessible cloud at low cost, then a hybrid cloud is a combination of the two clouds.

Quoted from Bisnis.com, the sectors that currently use hybrid cloud technology are electronic trading platforms (e-commerce), finance, game developers, transportation, and even the health sector because of the convenience and affordable prices offered by hybrid cloud.

Advantages of Using Hybrid Cloud:

1. Cost effectiveness
As is known, hybrid cloud platforms provide lower costs than other cloud platforms. You can easily use the public cloud and can at any time use the private cloud at a lower cost.

2. Security
No need to worry because all sensitive company data is maintained in the private cloud.

3. Storage
Hybrid cloud allows companies to have more efficient and large storage due to the integration of private and public clouds.

4. Reliability
When distributing data either from the private cloud to the public cloud or vice versa, the hybrid cloud can still produce optimal performance.

In terms of benefits, there are so many, ranging from secure data, cost efficiency and being able to freely choose which business runs on the Public Cloud or Private Cloud while still ensuring the integration of the two services.

The choice between solutions and deployments of public, private, and hybrid clouds depends on various factors, use cases, and limitations of each cloud. This also concerns what you need in your data storage needs and the level of security of your business data.
