On-Premises: A Complete Ownership Model
On-premises is a type of computing model which requires the user to manage and maintain their own hardware and software in-house. This means that all aspects of the system, such as backup, privacy, and updates, need to be managed and maintained internally. When the product is purchased, it must be installed on the user’s own servers, requiring additional hardware, database software, and operating systems to be purchased. With this model, the user has complete ownership of the system with no prior commitment.
On Cloud: Pay As You Use Services
Cloud computing refers to the delivery of on-demand services over the internet. This model allows users to access files and services online in a cost-efficient manner, without the need to manage them on a local storage device. Under this model, users pay only for the services they need, without having to purchase any additional software or licenses. This model also offers increased security, scalability, and reliability, as the services are managed by an experienced cloud provider.
Difference between On-Premises and On Cloud :
On-Premises vs. On Cloud: Scalability
On-premises set-up comes with limited scalability options and is expensive to scale up, with no option of scaling down. Conversely, cloud allows for cost-efficient scaling up and down without any infrastructure or maintenance costs.
On-Premises vs. On Cloud: Server Storage
On-premises requires significant space, power, and maintenance for server storage. Cloud solutions are offered by the provider and maintained by them, thus saving money and space.
On-Premises vs. On Cloud: Data Security
On-premises offers less security and requires physical and traditional IT security measures. On the other hand, cloud offers better security and eliminates the need for other physical and IT security measures.
On-Premises vs. On Cloud: Data Loss or Recovery
Recovering data in on-premises is difficult and time-consuming, whereas cloud offers backup for easier and faster data recovery.
On-Premises vs. On Cloud: Maintenance
On-premises requires an additional team for maintenance, which increases costs substantially. In contrast, cloud is maintained by the provider, thus eliminating the need for additional maintenance team.
