There is no doubt in the fact that Cloud Computing powers several organizations to enhance their productivity. Moreover, you should know about the popular cloud deployment models. These models help in connecting and accessing the cloud at its current location. In layman’s terms, how we access the cloud is referred to as the Deployment model. There are a total of 4 major types of Cloud Deployment Models:-
- Private Cloud Deployment Model
- Public Cloud Deployment Model
- Community Cloud Deployment Model
- Hybrid Cloud Deployment Model
Today, we are going to discuss each of them in detail and explain their various functions and features. We assure you that you will start learning everything from the basics and end up with advanced knowledge.
What is Deployment Model?
Deployment Model or the Cloud Deployment Model is a specific reference to the environment where the cloud lies and who controls it. Also, you should decide the type of deployment model prior to engaging the cloud computing system. As mentioned earlier, there are different types of deployment models that serve different requirements. Hence, it is important to justify the model according to your organization.
Without wasting any more time, let’s dive into the further classifications of deployment models.
Starting with the Private Cloud, it is a deployment model where only a particular company or group owns and accesses it. Thus, some also designate it as a corporate or internal model. A single organization duly manages all the systems and processes to get the results. However, the server may be hosted beyond the physical boundaries due to some reasons. No matter where they are, the internal management of hardware and software is quite in the hands of the owner.
Although, general users have the privilege to view a certain part of the cloud that is pre-determined by the organization. The best part of the Private cloud is that it belongs to a secure environment. Moreover, companies could easily customize it as everything is under their supervision. This leads to an increase in the maintenance cost due to the requirement of specialized staff and expensive hardware.
As the name suggests, the Public cloud is quite accessible by regular users or the normal public. All the data files are stored and managed by third-party service providers that charge for the same. Therefore, small companies don’t have to pay anything extra to operate the cloud computing features. Although, a paid service is always better than the free cloud as it is more secure and dependable. Moreover, you can adjust the price according to the resources that you require.
Some of the key advantages of using the Public cloud include low-cost maintenance, unlimited up-time, easy-to-extend feature, etc. However, there is no guarantee of any security of your data along with the lack of support service. Thus, you need to have a backup of important files present on the cloud. Amazon EC2 and Google AppEngine are common examples of the Public could.
Unlike the Private cloud, a group of organizations or companies take care of the services and resources in the Community Cloud. Although, other features are quite similar to the Private cloud. The owners in the group are mostly from the same background to enhance the overall usability of the cloud. The common infrastructure and resources are shared between the users and promote combined projects. The servers can either be managed collectively or could be given to a third-party service company.
This drastically decreases the cost and eventually increases the security and reliability of the cloud. Moreover, data sharing becomes quite effective. However, this deployment model is not commonly practiced. Further, a minor defect in the cloud will affect the entire system.
At last but not least, the Hybrid cloud has various innovative features of all the deployment models mentioned above. It is quite useful as organizations could implement the required features of each cloud accordingly. For instance, you can easily put the confidential data suing the Private cloud whereas non-critical data is shared through the Public cloud. It will help the organizations to manage their total resources more effectively.
The positive side of using a Hybrid cloud is you get a flexible environment where users can enjoy different features. Moreover, it is quite successful from the privacy point of view along with safeguarding important files.
