A public cloud is a computing model where a third-party provider makes computing resources—like servers, storage, and applications—available over the internet.1 These resources are shared among multiple users, and customers typically pay for what they use.2 Key characteristics include:

  • Shared Infrastructure: Resources are shared among many users.
  • Internet Access: Services are delivered over the public internet.
  • Scalability: Resources can be easily scaled up or down as needed.
  • Pay-as-you-go: Users typically pay only for the resources they consume.
  • Provider Management: The cloud provider manages the underlying infrastructure.
