Compute Shapes

A shape is a template that determines the number of OCPUs, amount of memory, and other resources that are allocated to an instance.

This topic provides basic information about the shapes that are available for bare metal instances, virtual machines (VMs), and dedicated virtual machine hosts.

Flexible Shapes

A flexible shape is a shape that lets you customize the number of OCPUs and the amount of memory when launching or resizing your VM. When you create a VM instance using a flexible shape, you select the number of OCPUs and the amount of memory that you need for the workloads that run on the instance. The network bandwidth and number of VNICs scale proportionately with the number of OCPUs. This flexibility lets you build VMs that match your workload, enabling you to optimize performance and minimize cost.

These are the flexible shapes:

  • VM.Standard.E3.Flex (AMD)
  • VM.Standard.E4.Flex (AMD)
  • VM.Optimized3.Flex (Intel)

Flexible memory is also available on flexible shapes. The amount of memory allowed is based on the number of OCPUs selected. The ratio of memory to OCPUs depends on the shape.

Shape Memory per OCPU Minimum Memory Maximum Memory
VM.Standard.E3.Flex 64 GB per OCPU 1 GB or a value matching the number of OCPUs, whichever is greater

1024 GB

Note: See this known issue about maximum memory.
VM.Standard.E4.Flex 64 GB per OCPU 1 GB or a value matching the number of OCPUs, whichever is greater

1024 GB

Note: See this known issue about maximum memory.
VM.Optimized3.Flex 64 GB per OCPU 1 GB or a value matching the number of OCPUs, whichever is greater 256 GB

These resources are billed at a per-second granularity with a one-minute minimum. Optimize your costs by choosing the shape that matches your workload and by changing the shape when your workload changes. For example, you can configure the VM to maximize compute processing power by choosing a low core-to-memory ratio. Or, for applications like in-memory databases or big data processing engines, configure an instance with a high core-to-memory ratio. Modify the OCPUs and memory as your workload changes, scaling up to increase performance or scaling down to reduce costs.

Supported Regions

E3 shapes are supported in all regions.

Note

When a new region becomes available, it might take a few weeks before host capacity also becomes available.

E4 shapes and Optimized3 shapes are supported in some regions. For a list, see the compute instance service limits for the following shape series:

  • BM.Standard.E4 cores
  • VM.Standard.E4 cores
  • BM.Optimized3 cores
  • VM.Optimized3 cores

As host capacity becomes available in additional regions, the list will be updated.

Bare Metal Shapes

The following shapes are available for bare metal instances:

Network bandwidth is based on expected bandwidth for traffic within a VCN. To determine which physical NICs are active for a shape, refer to the network bandwidth specifications in the following tables. If the network bandwidth is listed as "2 x <bandwidth> Gbps," it means that both NIC 0 and NIC 1 are active.

1: Instances are billed for the full amount of memory that you provision. Usable memory is reduced by up to 256 MB per instance. This difference is due to memory reserved to support the VM on the hypervisor.

1: The difference between billed OCPUs and usable OCPUs is due to OCPUs reserved for hypervisor use.

2: Because the DVH.Standard.E2.64 shape supports hosted VMs that use a previous generation shape series, it is available by request only.

Previous Generation Shapes

Oracle Cloud Infrastructure periodically releases new generations of Compute shapes. The latest shapes let you take advantage of newer hardware and a better price-performance ratio. When a shape is several years old, and newer generation shapes that are suited for the same purposes are available, the old shape transitions to become a previous generation shape.

Previous generation shapes are still fully supported. However, because the underlying hardware has reached the sustaining phase of its lifecycle, capacity in certain high-demand regions might be limited.

If you're using a previous generation shape, we encourage you to upgrade to a current generation shape.

Upgrading from a Previous Generation Shape

To upgrade from a previous generation shape to a current generation shape, you can do the following things:
