Private Cloud
The Private Cloud is quite similar to the Public Cloud. It overcomes the scalability and security issues experienced in the Public Cloud. Since the Private Cloud is not available to the general public, it is protected by a firewall making it more secure. Unlike the Public Cloud, the system is present on-premise in a Private Cloud. Private Cloud is considered the best option for companies working on big data projects having an enormous volume of data. Let us look at a few advantages of using the Private Cloud,
- In a Private Cloud, the company is the sole owner of the service possessing complete control of the services such as integration, regulations, user practices, and operations.
- In the Private Cloud, only authorized personnel is provided with access to the Cloud. This is ideal for the protection of the company data.
- Organizations can customize the solution according to their needs and demands.
- Public Clouds do not provide legacy applications, which is not the case with the Private Cloud.
- The Private Cloud is much more reliable than the Public Cloud.
- It also provides the company with more control over the configuration of the system according to their requirements.
- It provides a more enhanced quality of service to the clients.
There are a few drawbacks of using the Private Cloud some of them are.
- While using the Private Cloud, the organization might need to invest in very expensive software and hardware along with trained personnel.
- The scalability depends solely on the choice of hardware.
- The Private Cloud is maintained on-premise by the personnel requiring high maintenance.
- In a Private Cloud, the company may encounter issues regarding storage limitations.
Hybrid Cloud
The Hybrid Cloud Deployment Model is nothing but a combination of private and public models. Companies can have a mix of on-premise and cloud options using the Hybrid Model. The Hybrid Model can be used by all large-scale organizations as it combines the advantages of both the Private and the Public Cloud Deployment Models. Some of the merits associated with the Hybrid Model are,
- Organizations can drastically reduce operational costs using the Hybrid model.
- The Hybrid Model allows the company to combine two or more separate models together.
- The security protocols are more straightforward in the Hybrid Model. Thus it is easy to protect the system from external threats.
- The companies can easily customize the solutions to match their individual requirements.
- Due to the combination of two or more models, it is easier to make the system more scalable in a Hybrid Model.
The Hybrid Model comes with its drawbacks. Some of the drawbacks of using the Hybrid Model are,
- Hybrid Models are a very complex setup, and it is very tedious work to manage them.
- Hybrid Models are only useful if the company has a varied use demand for the management of the workloads.
- Hybrid Models can have a dependency on the infrastructure of the organization.
- Attackers can violate the security of the Hybrid Model from the Public Cloud back door.
Multi Cloud
The last Cloud Model is the Multi Cloud. The Multi Cloud is a combination of multiple Public Clouds. The organization may use various Public Cloud Deployment Models, one for database, another for authentication, another as PaaS, and so on. Let us look at a few of the advantages of using the Multi Cloud,
- Multi Cloud Deployment Model can prove to be pretty cost-effective for organizations. Dividing the Cloud among different vendors helps reduce the cost of deployment.
- By dividing the Cloud among the vendors, companies can have a variety of vendors to choose from. Organizations can choose the best vendors for a specific task.
- The Multi Cloud Deployment Model proves to be more reliable than any other Cloud Deployment Model.
Let us also look at the drawbacks of using the Multi Cloud Model,
-
Similar to the Hybrid Model, the Multi Cloud Model requires a very complex setup and can be tedious work to manage.
- Since the Multi Model is a combination of Public Models, it is very likely to encounter attacks and is not very secure.
