A company runs its e-commerce platform in Azure but keeps HR systems on-premises. Which deployment model does this represent?

This scenario describes a hybrid cloud model because it combines both public cloud resources (Azure for the e-commerce platform) and private cloud resources (on-premises for HR systems). This approach allows organizations to leverage the scalability and flexibility of the public cloud while maintaining control and security over sensitive data or legacy applications within their private infrastructure. A public cloud involves all resources being hosted by a third-party provider and accessible over the internet. A private cloud refers to computing services offered either over the internet or a private internal network and only to select users instead of the general public. A community cloud is shared by several organizations with common concerns.
