The different deployment models for Oracle Cloud are:
1. Public Cloud: This model allows customers to access cloud services directly over the internet. For example, Oracle Cloud Infrastructure (OCI) provides users with access to compute, storage, networking, database, and other cloud services.
2. Private Cloud: This model provides customers with dedicated cloud resources that are managed by Oracle. For example, Oracle Private Cloud Appliance (PCA) provides customers with a complete cloud infrastructure solution that can be deployed on-premises or in a data center.
3. Hybrid Cloud: This model combines public cloud services with private cloud resources to create a hybrid cloud environment. For example, Oracle Cloud at Customer (CaaC) provides customers with a fully managed cloud environment that can be deployed on-premises or in a data center.
4. Multi-Cloud: This model enables customers to deploy their applications and services across multiple cloud providers. For example, Oracle Cloud Marketplace allows customers to access, deploy, and manage Oracle Cloud services, as well as third-party cloud services, in a single dashboard.
