ECS Bare Metal Instance

An elastic and horizontally scalable high-performance computing service providing the same computing performance as traditional physical servers including physical isolation.

Based on next-generation virtualization technology independently developed by Alibaba Cloud, ECS Bare Metal Instance features both the elasticity of a virtual server and the high-performance and comprehensive features of a physical server. Compared with its predecessor, the next-generation virtualization technology of these instances excel in supporting standard Elastic Compute Service (ECS) and nested virtualization technology. This enables you to retain the elasticity capability of common ECS while delivering the same user experience as physical servers.
