Differences between OCI-C and OCI?

Question

Oracle has the same services on their new platform Oracle Cloud Infrastructure (OCI) and Oracle Cloud Infrastructure - Classic (OCI-C).

What are the differences between these two platforms? Do the hypervisors differ?

Answer 1

Both OCI and OCI-C are platforms for IaaS.

OCI-C

• formerly called Oracle Public Cloud (OPC)
• Based on Xen hypervisor
• Offers VMs only
• Elastic of Dedicated Compute

OCI

• Essentially a rebranding of Oracle's Bare Metal Cloud Service (BMCS)
• Hypervisor based on KVM
• Offers VMs and Bare Metal compute
• Compute, Availability Domain, Virtual Cloud Network, and Edge deployment

There's also Cloud at Customer (C@C or just CC) where you "subscribe" to the cloud services but the servers are kept on the customer's premises.

Answer 2

To add on to that, OCI now has tons of services. Check out their status page for more https://ocistatus.oraclecloud.com/ I think this one is still missing services like service gateway.

Answer 3

From https://blogs.oracle.com/generation-2:-oracle-cloud-infrastructure

One can think of the first-generation cloud as built for cloud native, net-new applications. Gen 2 cloud infrastructure is excellent for those use cases as well, but it also enables enterprises to replace on-premises data centers with a cloud deployment model.

Oracle Cloud Infrastructure is Oracle’s gen 2 cloud infrastructure, and it’s what we’re building and operating today. It’s purpose-built for the enterprise and couldn’t have been built 10 years ago or 5 years ago, from both an architecture and an open-source-capabilities perspective.

Oracle Cloud Infrastructure is available globally, and it has the feature set, the capabilities, and the differentiation to run all the mission-critical, high-volume, high-performance data­bases and workloads for the world’s most demanding enterprises. Oracle Cloud Infrastructure is ready for any and all workloads.
