Which cloud model is typically used to host a public-facing e-commerce website?

Public Cloud is the most suitable model for a public-facing e-commerce website because it offers high scalability, reliability, and cost-effectiveness. Resources are provisioned on-demand from a shared pool of computing resources owned and operated by a third-party provider, allowing the website to handle fluctuating traffic without significant upfront investment. Private Cloud involves dedicated infrastructure, which is more expensive and less flexible for public-facing applications with variable demand. Hybrid Cloud combines public and private clouds, often used for specific workloads or data residency needs, but a purely public cloud is sufficient and often preferred for a standard e-commerce site. Offline Cloud is not a recognized cloud computing model.
