Public and private clouds differ primarily in terms of accessibility and management. A public cloud is a shared infrastructure, where services are offered over the internet to multiple organizations, facilitating scalability and cost-effectiveness. In contrast, a private cloud is exclusively used by a single organization, providing greater control and customization over the environment. While public clouds typically offer flexibility and convenience, private clouds enhance data security and compliance, making them suitable for businesses with sensitive data or stringent regulatory requirements. Hybrid models also exist, combining elements from both.
