Public cloud storage is when a provider uses their servers to store your data. It's easy to scale and cost-effective, but you share resources with other users, which might not be ideal for sensitive data. Private cloud storage means your data is stored on servers dedicated only to your business. It's more secure but also more expensive.  Hybrid cloud storage combines the best of both worlds. You can store sensitive data on a private cloud and less-sensitive data on a public cloud. This way, you get the security of a private cloud and the cost-effectiveness of a public cloud.
