What Is BMS?

Overview

A Bare Metal Server (BMS) features both the scalability of VMs and high performance of physical servers. It provides dedicated servers on the cloud, delivering the performance and security required by core databases, critical applications, high-performance computing (HPC), and Big Data.

The BMS self-service feature allows you to apply for and use a BMS on demand. To apply for a BMS, you need to specify the server type, image, required network, and other configurations. You can obtain the BMS you require within 30 minutes.

System Architecture

BMS works with other cloud services to provide computing, storage, network, and image functions.

  • BMSs are deployed in multiple availability zones (AZs) connected with each other through an internal network. If an AZ becomes faulty, other AZs in the same region will not be affected.
  • With the Virtual Private Cloud (VPC) service, you can build a dedicated network, set subnets and security groups, and allow the VPC to communicate with the external network through an EIP (bandwidth support required).
  • With the Image Management Service (IMS), you can install OSs on BMSs or create BMSs using private images for rapid service deployment.
  • Elastic Volume Service (EVS) provides storage and Volume Backup Service (VBS) provides data backup and restoration.
  • Cloud Eye is a key measure to monitor BMS performance, reliability, and availability. Using Cloud Eye, you can view BMS resource usage in real time.
  • Cloud Backup and Recovery (CBR) backs up data for EVS disks and BMSs, and uses snapshot backups to restore the EVS disks and BMSs.

Access Methods

The public cloud provides a web-based service management system (management console). You can access BMS through the management console or HTTPS APIs. The two access methods differ as follows:

  • API

    If you want to integrate BMS into a third-party system for secondary development, use APIs to access the BMS service.

    This method will be available in later versions.

  • Management console

    For all other purposes, use the management console.
