Cloud computing has become an unavoidable option for businesses looking to scale up. A revolution in the world of information technology, the cloud offers a plethora of benefits to businesses. However, before moving to the cloud, it is important to understand the different computing models like private cloud, public cloud, and hybrid cloud. In this article, we will talk about public and private clouds and the difference between them.
What are Public and Private Clouds?
A public cloud is a type of computing service where a provider offers cloud services over the internet. This is usually offered on a pay-as-per-use model. The service provider takes responsibility for setting up and managing the data centre. This ensures that you don’t have to spend time and money to purchase and maintain the infrastructure required for the cloud. Some popular public cloud providers are Amazon Web Services, Microsoft Azure, Google Cloud, Cisco, etc.
A private cloud resides on a hosted data centre behind a firewall or on the organization’s intranet. The company is responsible for managing, maintaining, and updating the data centre. If the cloud requires a replacement of servers or any additional hardware, then the company has to procure it. A private cloud is a good option for organizations with expensive data centres as they can use their existing infrastructure to host the cloud. A private cloud has dedicated resources which has a direct impact on the performance and security of the cloud.
Difference between a Private Cloud and a Public Cloud:
|Private Cloud||Public Cloud|
|Dedicated Infrastructure||The infrastructure is dedicated to your business and is managed by your team||The infrastructure is shared between multiple users and is managed by the service provider|
|Suitable for||Businesses which require high levels of security, great performance, and good control over the computing environment||Businesses which are looking for affordable options with adequate room to grow|
|Recommended for||Protecting your critical and sensitive applications and/or data||Testing applications and as a disaster recovery option for small businesses|
|Scaling of Resources||You can scale up or down as per your requirement since the data centre is in-house||Scalability depends on the service agreement with the service provider|
|Who maintains the cloud?||A private cloud is maintained by a team of in-house technical administrators||A public cloud is managed by the technical team of the service provider|
|Pricing||A private cloud has a huge upfront cost since you will have to purchase hardware, software, and hire staff too. Additionally, maintenance and scaling options need to be included in the regular costs too||Most public clouds offer the pay-as-you-go model, making them highly affordable|
|Security||Dedicated resources and an isolated network environment make a private cloud highly secure||A public cloud offers basic security compliance|
|Performance||High levels of performance due to dedicated resources||Shared resources can have an impact on performance levels|
