Cloud computing has been around for quite a while now and has been adopted by small and large organizations alike due to its numerous benefits. Reduced costs, scalability, visualization of resources, the ability to expand the server base at need and instant provision of resources are just some of the characteristics of cloud computing that make it popular. However, when choosing a cloud computing model for your business, there can be confusion as to whether to adopt a private cloud model or a public one. We discuss the pros and cons of both models in detail.
Private Cloud Computing
As evident from the name, a private cloud is a company’s internal or private cloud system that exists and resides on the company’s intranet making use of its data centers and is protected by a firewall.
A private cloud hosting solution is dedicated to a single organization, and thus it can be designed to have its hardware, network and data storage separate and inaccessible to other clients in the same data center. This ensures high levels of security.
The hardware, network, and storage performance levels can be customized per the personal needs of the organization at will.
If a certain large database application requires a dedicated server, then that dedicated server can also be incorporated to work with a virtual private cloud.
A private cloud is an organization’s cloud system, and all responsibility for its maintenance, management, and security is up to the company itself.
Public Cloud Computing
A public cloud solution requires the services of a cloud service provider and in this case, leaves the management and responsibility of all affairs of your cloud system up to the provider. Your data is stored on the provider’s system. Public clouds are more economical and reduce testing and deployment time for new products.
Public clouds work on pay-as-you-go model where you pay for the services you are using and are not bound by any contract. Only pay for as much infrastructure you’re using and discontinue at any time you want.
As mentioned above, there is no contract that binds you to ongoing use of the server. You can stop using at any time and pay only the amount of time that you used the services.
A public cloud is a shared environment in the sense that there are multiple users making use of the same servers, hardware, network, and storage.
Whereas private clouds provide a surety of security, the cost of developing a fully functioning private cloud can be huge. With time the servers will need to be replaced which is also expensive. So, private cloud model is not an option for small organizations. Public clouds offer more ease of use and your data although shares storage with other clients’ data it is still kept separate. However, companies still have concerns over the security of public clouds. Even then, security breaches of a public cloud are a rare event.
