Describe the difference between cloud computing and traditional on-premises IT solutions.

Cloud computing fundamentally differs from traditional on-premises IT solutions primarily due to its architecture and deployment method. The correct answer highlights that cloud computing provides scalable access over the internet, which allows users to utilize computing resources on-demand, often without the need for significant upfront investments in physical hardware. In contrast, traditional on-premises solutions necessitate the establishment and maintenance of physical infrastructure within an organization’s premises, which can limit scalability and flexibility.

With cloud computing, resources can be scaled up or down easily to meet demand, allowing businesses to pay only for what they use. This elasticity is a key advantage over on-premises solutions, which typically require businesses to purchase fixed capacity and manage that infrastructure, often resulting in higher costs and inefficiencies, especially if demand fluctuates.

Thus, the ability to quickly and efficiently scale cloud resources, as well as to access them from anywhere via the internet, represents a significant shift in how IT services can be deployed and utilized compared to traditional models. This makes the correct answer particularly relevant in understanding the modern IT landscape.
