Cloud services delivered over the public internet by third-party providers, shared across multiple customers.
Public cloud refers to cloud services delivered over the public internet by providers like Microsoft, Amazon, and Google. Resources are shared across multiple customers (multi-tenant), though logically isolated. Public cloud offers economies of scale, global reach, and elastic capacity. Security concerns about public cloud have largely been addressed through strong isolation, compliance certifications, and security features—public cloud is often more secure than on-premises infrastructure.
Why It Matters
The DSC Perspective:
Public cloud misconceptions persist. Modern public clouds offer robust security and compliance certifications. The question isn't whether public cloud is secure, but whether your use of it is properly configured and managed.
