Examples :- VMware vCloud, OpenStack, Microsoft Azure Stack, Oracle Cloud at Customer, IBM Cloud Private etc…
III) Hybrid Cloud
Hybrid Cloud is collaborative with public and private cloud services, offering strengthening and scalability with on-premises data security, perfect for diverse workloads in cloud computing.
Examples :- AWS Outposts, Azure Arc, Google Anthos, IBM Cloud Satellite, Oracle Cloud at Customer etc…
Multi-Cloud is using multiple service providers for different purposes through merging both public and private clouds.
Examples :- AWS Outposts, Azure Stack, Azure Arc, Microsoft Azure VMware Solution etc…
