Virtual Machines (VMs)

A flexible shape lets users customize the number of virtual CPUs (vCPUs) and the amount of memory (RAM) when launching or resizing virtual machines. The network bandwidth and number of virtual network interfaces (VNICs) scale proportionately with the number of OCPUs. This flexibility lets engineers build VMs that match their workloads, enabling the organization to optimize performance and minimize cost.

Features

• Support AMD, Arm-based Ampere, and Intel processors
• Maximum cores: 94 (188 vCPUs)
• Maximum memory per core: 64 GB per core
• Minimum memory: equivalent to number of cores (starting at 1 GB)
• Maximum memory: 5,120 GB

Standard instances are designed for general-purpose workloads and suitable for a wide range of applications and use cases. Standard shapes provide a balance of cores, memory, and network resources, and are available with Intel, AMD, and Arm-based processors. Dense I/O shapes can be used for large databases, big data workloads, and applications that require high-performance local storage. GPU shapes include Intel or AMD CPUs and NVIDIA graphics processors for AI/ML workloads and video rendering. Optimized shapes are ideal for high performance computing (HPC) workloads.

Features

• Standard shapes support AMD, Arm-based Ampere, and Intel processors
• Additional shapes include dense I/O, GPU, optimized, and DVH
• Dense I/O shapes for applications that require high-performance local storage
• GPU shapes for hardware-accelerated workloads
• Optimized shapes for workloads that require high-frequency processor cores

Burstable instances provide a baseline level of CPU performance with the ability to burst to a higher level to support occasional spikes in usage. Burstable instances are designed for scenarios where an instance is typically idle or has low CPU utilization with occasional spikes in usage. They're also ideal for scaled-down workloads that don't require a full core.

Preemptible instances improve economics for workloads that only need to run for brief periods or that can be interrupted when the capacity is reclaimed. Preemptible instances behave the same as regular compute instances, but the capacity is reclaimed when it's needed elsewhere, and the instances are terminated.

Confidential instances protect data while in use at the hardware level. Securing the in-memory data processed on compute instances reduces the threat of data leakage or compromise due to vulnerabilities in underlying infrastructure components.

Shielded instances harden the firmware security on bare metal hosts and virtual machines (VMs) to defend against malicious boot level software. Shielded instances use the combination of Secure Boot, Measured Boot, and the Trusted Platform Module (TPM) to harden the firmware security on OCI instances. Shielded instances running on Windows Server 2016 or Windows Server 2019 support Windows Defender Credential Guard, which uses the TPM to protect virtualization-based security encryption keys.

On-demand capacity

Pay for only the compute capacity consumed. With on-demand capacity, customers pay for compute capacity by the second, and pay only for the seconds that their instances are running.

Reserved capacity

Reserve capacity for future usage, and ensure that capacity is available to create compute instances whenever it’s needed. When instances are terminated, the capacity is returned to the reservation, and the unused capacity in the reservation increases.

Dedicated capacity

Run VM instances on dedicated servers that are a single tenant and not shared with other customers. This feature lets customers meet compliance and regulatory requirements or to meet host-based licensing requirements.
