This topic describes ECS Bare Metal Instances and their instance families and instance types.

Overview

ECS Bare Metal Instances are a compute service that combines the elasticity of virtual machines and the performance and features of physical machines. ECS Bare Metal Instances are designed based on the state-of-the-art virtualization 2.0 technology developed by Alibaba Cloud. The virtualization technology used by ECS Bare Metal Instances is optimized to support common ECS instances and nested virtualization, maintaining the elastic performance of ECS instances and the performance and features of physical machines.

ECS Bare Metal Instances combine the strengths of both physical machines and ECS instances to deliver powerful and robust computing capabilities. ECS Bare Metal Instances use virtualization 2.0 to provide your business applications with direct access to the processor and memory resources of the underlying servers without virtualization overheads. ECS Bare Metal Instances keep the hardware feature sets (such as Intel® VT-x) and resource isolation capabilities of physical machines, ideal for applications that need to run in non-virtualization environments.

By virtue of the independently developed chips, hypervisor system software, and the redefined server hardware architecture, ECS Bare Metal Instances integrate features from both physical and virtual machines. ECS Bare Metal Instances can seamlessly connect with other Alibaba Cloud services for storage, networking, and database tasks. ECS Bare Metal Instances are fully compatible with ECS instance images. These properties allow you to build resources to suit your business requirements.

When you use ECS Bare Metal Instances, note the following items:
  • ECS Bare Metal Instances do not support instance type changes.
  • If a hardware fault occurs to an ECS Bare Metal Instance, a failover occurs and data is retained in the disks of the ECS Bare Metal Instance.

Benefits

ECS Bare Metal Instances provide the following benefits through technological innovation:
  • Exclusive computing resources

    As a cloud-based elastic computing service, ECS Bare Metal Instances deliver the same performance and resource isolation as standard physical machines and can ensure the exclusivity of computing resources without virtualization overheads or feature loss. ECS Bare Metal Instances support 8, 32, 80, 96, or 104 vCPUs and high clock speeds. An ECS Bare Metal Instance with eight vCPUs can provide a core frequency of 3.7 GHz to 4.1 GHz for better performance and faster response for gaming and finance businesses than peer services.

  • Chip-level security

    For security, ECS Bare Metal Instances use a chip-level trusted execution environment (Intel ® SGX) in addition to physical server isolation to ensure that encrypted data can only be computed within a secure and trusted environment. This chip-level hardware security protection provides a safe box for your data in the cloud and allows you to control all data encryption and key protection processes. For more information, see Install SGX.

  • Compatible with multiple private clouds

    ECS Bare Metal Instances can address the needs of high-performance computing and help you build new hybrid clouds. Thanks to the flexibility, elasticity, and other strengths inherited from the mix of physical and virtual machines, ECS Bare Metal Instances can implement re-virtualization. Offline private cloud business can be seamlessly migrated to Alibaba Cloud without performance overheads arising from nested virtualization, giving you a new method to move businesses onto the cloud.

  • Support for heterogeneous instruction set processors

    Virtualization 2.0 used by ECS Bare Metal Instances is developed independently by Alibaba Cloud, and supports instruction set processors such as ARM at no additional cost.

Comparison of ECS Bare Metal Instances, physical machines, and virtual machines

Compared with a physical machine with the same configurations, an ECS Bare Metal Instance delivers greater performance. During Double 11, ECS Bare Metal Instances delivered robust computing capabilities with millions of vCPUs to handle traffic spikes.
