Cloud computing is the integration of all your business or personal storage needs in the cloud. It provides you with remote access to a data storage tool. One of the main reasons for it to be extremely famous today is the fact that it is incredibly versatile and can act as an instant storage solution for many businesses.

In the past few years, cloud computing has revolutionized the entire IT infrastructure. It has made access to affordable data servers, without physical or data storage limitations.

Previously, many companies struggled to find a reliable and cost-effective storage solution for their data. Cloud computing has brought about a solution to this problem, and many others.

Cloud Computing – deployment models

Cloud computing is divided into three basic types for deployment:

• Private Cloud
• Public Cloud
• Hybrid Cloud

Private Cloud

A private cloud is a cloud tailored specially for a specific business over the internet or a private internal network. It is not available for the general public as it is an internal or a corporate cloud. The private cloud offers several features, such as self-service, high scalability, and flexibility.

The private cloud guarantees complete control to the users as it allows full customization. However, if an organization ever decides to migrate to a private cloud, they should first decide if they want to operate it themselves or hire a third-party resource.

One small drawback of transitioning to a private cloud is the fact that the IT function of the organization needs to bear complete responsibility of the associated cost and management responsibility. Therefore, you require quite a few professional individuals to deal with the management, organization, and maintenance of the cloud.

Private cloud services can either be used as a SaaS or a PaaS. Furthermore, it can be combined with the public cloud to render hybrid cloud services.

A private cloud offers privacy and security like no other. Firstly, their access is limited, therefore, no external source can tap into your precious data. So, it provides a secure cloud environment, protected by firewalls, and under IT surveillance always.

Secondly, as it allows full customization, you can set it according to your needs, and align it with your requirements. This feature gives you full control over the cloud.

However, the private clouds are a tad bit more expensive than the other types, as they can only cater to a single business at a time. They do also require full-time surveillance form the company.

Azure App Services  is an excellent example of private clouds!

Public Cloud

The public clouds are over-the-internet apps available for the greater audience. They are usually free, or they sometimes charge a very nominal service fee. The public clouds are, however, best for personal use, as they are a public resource.

The service is cost-effective, user friendly, and easily available for all users. However, it is not as customizable as the former cloud service that we discussed. This is because this service caters to a larger clientele rather than a specific entity. Therefore, it is generalized and not customized according to an individual’s needs.

Both the public and the private cloud are very similar if we compare the architecture, but they are quite different from services and security perspectives.

Public clouds are less secure than private clouds, but that does not mean that your data is exposed to the world. There are several steps that you can take to tighten the security of your cloud space.

The public clouds come with multiple benefits, such as cost-effectiveness, user-friendliness, high scalability, and remote accessibility.

There are several public clouds in the market, such as ESDS eNlight Cloud, Amazon Elastic Compute Cloud (EC2), IBM Blue Cloud, Sun Cloud, Google AppEngine, and Windows Azure Services Platform. 

Hybrid Cloud

Hybrid cloud is a cross between the two parent types, private and public. A hybrid cloud allows an organization to combine the powers of the two and mix and match to create a cloud that cloud that specifically caters to their business needs. It helps them to eliminate any limitations that they might face if they use any single deployment type.

This ensures that they have a fully customizable deployment service to store all of their highly critical and sensitive data.

The hybrid cloud fully depends on the business requirements, such as the level of data security, control structure, and the compliance requirements.

It also offers a pay as you go model so that both the pricing and the scalability won’t be an issue if you can control and manage the cloud in an optimized manner. High scalability also promises a much more flexible infrastructure.

Conclusion

It is important to be sure of your personal and professional needs before selecting the deployment model. This will make your transition and maintenance much smoother and more manageable.
