What is the difference between on-premises and cloud?

There is a list of the key differences between on-premise and cloud computing:

1. Location and hosting

• On-premise: IT infrastructure and software is located and hosted within the organization's own physical premises.
• Cloud: IT resources are hosted off-site by a third-party cloud service provider and accessed over the internet.

1. Control and Ownership

• On-premise: Organization has full control and ownership over the hardware, software, and data.
• Cloud: Cloud provider manages the underlying infrastructure, while the organization has less direct control.

1. Security

• On-premise: Organizations can have tighter control over security and compliance, but must manage it themselves.
• Cloud: Cloud providers typically offer robust security measures, but organizations cede some control to the provider.

1. Scalability

• On-premise: Scaling up or down infrastructure can be more difficult and costly.
• Cloud: Scaling resources up or down is generally easier and more flexible.

All in all, on-premise provides more control and customization, while cloud computing offers greater flexibility, scalability and potentially lower costs, but with less direct control over the infrastructure.
