On-Premise vs. Public Cloud

Cloud storage has become prominent for all the business practices. There are various types of cloud storage like public cloud, private cloud, and hybrid cloud. There are a number of factors an organization must consider while deciding on the right cloud infrastructure.

In Public Cloud, a third party provider makes available resources like storage, storage upgrades, and applications to the public. Companies can pay and use the cloud services as per their need, and scale the usage up or down based on the company needs.

In Private On-Premise the cloud services are hosted in the subscriber’s premise. The subscriber has to maintain the cloud by making all the arrangements for the infrastructure. The enterprise has to bear the cost of hosting, maintaining and troubleshooting the infrastructure.

The key differences between On-Premise vs. Public cloud are:

Cost:

On-Premise: The company hosting the cloud is responsible for managing and troubleshooting the infrastructure which is a costly affair. They are also responsible for bearing the cost of servers, power, and space.

Public cloud: These cloud services are used by multiple subscribers, and the user has to pay for the resources they use. Public cloud does not have any kind of maintenance cost, and the price can be adjusted as per the requirement of the user.

Security:

On-Premise: Users have the flexibility to implement security measures as per the needs of the company. Security becomes the priority for banking and government sectors, where opting to On-Premise cloud makes sense.

Public cloud: Security is the primary concern with public cloud. Here the users are responsible for taking care of the security of their data and applications on the cloud.

Compliance:

On-Premise: Subscriber will have to comply with local laws when they are storing public data. In the case of On-Premise cloud, it is possible to customize the cloud as per the requirement to meet the regulations.

Public cloud: The companies opting for Public Cloud should carry out a thorough study of the third party cloud provider to ensure that they follow the mandates of the industry. Sensitive data has to be secured, and customers and employees should have their privacy ensured.

Deployment:

On-Premise: Here the resources are deployed in-house, and the company is responsible for its running and maintenance. The company might have to engage a team in running the cloud infrastructure.

Public cloud: The resources in public cloud are hosted in the premises of the service provider. The company can access these resources and use as per their requirement. The process of deployment is comparatively easier in the public cloud.

 Reliability:

On-Premise: Private On-Premise cloud has least chances of downtime of servers and hence are highly reliable.

Public cloud: The application hosted on public cloud are prone to outages, and this can impact the business.

Control:

On-Premise: In On-Premises cloud, the company has complete control over the data hosted in the cloud. For companies with privacy concerns, this feature is a big add-on.

Public cloud:  Since the data is hosted within the server of the third-party provider, in case of unexpected event or server downtime business might be hampered. Data and encryption key reside within the third-party provider and hence ownership of data is a concern here.
