OCI provides flexible compute options ranging from virtual machines and bare metal servers to container instances. This lesson focuses on OCI Compute — the core service for running virtual servers.
OCI organises compute resources into shapes that define the vCPU, memory, and networking:
| Shape | Type | Use Case |
|---|---|---|
| VM.Standard.E4.Flex | AMD EPYC (flexible) | General purpose |
| VM.Standard3.Flex | Intel Xeon (flexible) | General purpose |
| VM.Standard.A1.Flex | Arm Ampere A1 (flexible) | Cost-effective, cloud-native |
| VM.Optimized3.Flex | Intel (high frequency) | HPC, gaming |
| VM.GPU.A10 | NVIDIA A10 GPU | AI/ML, rendering |
| BM.Standard.E4 | AMD bare metal | High performance, dedicated |
Flexible shapes let you choose the exact number of OCPUs and amount of memory:
OCPU = Oracle CPU. 1 OCPU = 1 physical CPU core with hyperthreading = 2 vCPUs on other clouds.
