Options
- APrivate cloud
- BHybrid cloud
- CCommunity cloud
- DPublic cloud
Explanation
A hybrid cloud model allows an organization to integrate existing on-premises networks with cloud-based services, providing businesses with both the security of a private cloud and the computing power of a public cloud when needed (see ISC2 Study Guide, Chapter 4, Module 3). For example, consider a bank that has been running its IT infrastructure on-premises. This bank decides to start using a cloud- based AI tool for credit risk analysis, but it doesn't want to put sensitive customer data in the public cloud. The bank could opt for a hybrid cloud, keeping sensitive customer data on-premises (private cloud) while using the AI tool (public cloud) on anonymized data. Meanwhile, a private cloud is basically an on-premises cloud or a dedicated cloud environment that does not interact with public clouds and would not allow integration of legacy networks. A public cloud is everywhere on the Internet and does not allow integration with private, on-premises networks. A community cloud is a cloud shared by multiple organizations with similar needs. While it's possible to integrate on-premises systems into a community cloud, this option would typically not be the first choice due to security and privacy concerns.
