How does a public cloud differ from a private cloud?

A public cloud is defined by its architecture and service model, which allows multiple customers to share infrastructure and services that are hosted by third-party providers. This shared environment enables organizations to access scalable computing resources without having to invest in the physical hardware and maintenance associated with traditional on-premises data centers.

By contrast, a private cloud is designed specifically for one organization, offering a dedicated environment where resources are not shared with others. This can lead to enhanced security and customization but often results in higher costs and maintenance responsibilities.

The nature of public clouds also allows for greater flexibility and cost-effectiveness, making it attractive for businesses that want to rapidly adjust resources according to demand. Ultimately, public clouds leverage centralized services and shared infrastructure, which is a fundamental characteristic that distinguishes them from private clouds.
