Application scenarios of BMSs
BMSs are used in the following scenarios: 1. Security- and Monitoring-Demanding Scenario Financial and securities industries have compliance requirements on service deployment, and some customers have strict data security requirements. The BMS service ensures exclusive, dedicated resource use, data isolation, as well as operation monitoring and tracking. 2. High-Performance Computing Scenario High-performance computing, such as the supercomputer center and genome sequencing, needs to process a large amount of data. Therefore, these scenarios require high computing performance, stability, and timeliness. BMSs can meet your high-performance computing requirements for performance overheads caused by virtualization and hyperthreading have few impacts on BMSs. 3. Core Database Scenario Some key database services cannot be deployed on VMs and must be deployed on physical servers that have dedicated resources, isolated networks, and assured performance. The BMS service provides high-performance servers dedicated for individual users, meeting user requirements in this scenario.

Technology advantages of BMSs
Technology advantages of BMSs: 1. Hybrid Deployment and Flexible Networking BMSs within an AZ can communicate with each other through an internal network. VPCs can be used to connect BMSs and external resources. You can also use BMSs together with other services, such as ECS, to achieve hybrid deployment and offer flexible networking to meet requirements in complex application scenarios. 2. High Stability and Reliability, and Optimal Performance The BMS service provides dedicated BMSs for tenants. The tenants can exclusively enjoy stable performance provided by physical servers, meeting such service requirements as high-performance, stability, data security, and regulation. 3. High Throughput and Low Latency The BMS provides tenants with a high-throughput and low-latency network in an AZ. The BMS service can provide a maximum bandwidth of 10 Gbit/s and a minimum latency of 25 μs. This network can be used in scenarios requiring high throughput and low latency. For example, you can use the network on the Oracle RAC heartbeat network plane.
