2. Scalability: Cloud computing offers the ability to easily scale resources up or down based on demand, allowing organizations to quickly adapt to changing needs. On-premises computing requires additional hardware and infrastructure investments to scale.
3. Maintenance and Updates: Cloud computing providers handle the maintenance, updates, and security of the infrastructure and services, relieving organizations from these responsibilities. In on-premises computing, organizations are responsible for maintaining and updating their own infrastructure.
4. Accessibility: Cloud computing allows users to access resources from anywhere with an internet connection, enabling remote work and collaboration. On-premises computing may have limitations on accessibility, requiring users to be physically present in the organization's premises.
Overall, cloud computing offers flexibility, scalability, cost-efficiency, and reduced maintenance burden, while on-premises computing provides more control and customization options but requires higher upfront investments and ongoing maintenance efforts.
