What is Bare Metal and specific application scenarios

Bare Metal, Do we see bare metal servers in many cloud service providers? From the configuration point of view, the configuration hardware must be very large, much larger than the virtual ECS, and of course the price is relatively high. What's the use of this? From the configuration point of view, it must be used for medium and large projects, such as running AI business or remote services for cloud office business, but some friends may not know.

1. Difference between bare metal server and virtual host

characteristic Bare metal server virtual machine
Resource isolation The physical server resources are completely exclusive, without resource sharing Resource virtualization, multiple virtual machines share the same physical hardware resources
performance Higher performance due to no virtualization overhead There will be some performance loss, and the virtualization layer adds additional overhead
flexibility Full control of hardware and operating system, flexible configuration High flexibility, but limited by the virtualization layer
Management complexity Need higher hardware and network management skills Management is relatively simple, and the virtualization platform provides centralized management functions
Applicable scenarios High performance computing, big data, financial transactions, high demand databases, etc Daily business, test environment, efficient utilization of virtualized resources, etc

2. Application scenario of bare metal server

High performance computing (HPC) For applications that require a lot of computing resources (such as scientific computing, engineering simulation, rendering, etc.), bare metal servers can provide higher computing performance than virtual machines, and reduce the performance loss caused by virtualization. For example, in the fields of weather prediction, genome analysis, financial modeling, etc., high-performance computing often requires bare metal servers to ensure that computing tasks can be completed quickly.

When processing large data sets, such as Hadoop, Spark and other distributed computing frameworks, bare metal servers can provide more memory and storage capacity to ensure that data can be loaded, processed and stored efficiently. Virtualization may introduce resource allocation complexity and additional overhead, while bare metal servers provide native performance.

Game hosting and rendering game servers, especially multiplayer online game (MMO) servers, usually require high CPU and memory resources, especially when real-time computing is involved in games. The bare metal server can ensure low latency and high performance for high concurrent user access.

The bare metal server is an ideal choice for database applications that require high performance and low latency. Traditional relational databases (such as MySQL, PostgreSQL) or large-scale distributed databases (such as Cassandra, MongoDB) can better optimize performance through bare metal servers to avoid bottlenecks in the virtualization layer, especially in the case of high concurrency and large data volume.

Financial industry and trading platform Some high-frequency trading platforms in the financial industry have high requirements for delay. The bare metal server can provide lower latency and higher stability, and avoid the additional delay caused by virtualization, so it is the first choice in the field of financial services and securities trading.

Private cloud infrastructure In some cases, enterprises may want to build their own private cloud and fully control hardware resources. The bare metal server provides a high-performance infrastructure without relying on the virtualization layer in the public cloud. This is very important for data sensitive enterprises (such as government agencies, large banks, etc.).

Although container technology (such as Docker) is usually used with virtual machines, bare metal servers can provide an ideal running environment for container applications when it is necessary to ensure higher performance and exclusive resources. Many high-performance containerized workloads (such as machine learning training, containerized databases, etc.) can achieve better performance in bare metal environments.

Real time data processing and streaming media applicationsStreaming media applications, video processing and real-time data stream processing require the system to have high throughput and low latency. The bare metal server can provide these requirements, especially in scenarios such as high traffic video conference, large-scale live streaming or low latency audio and video processing.

Private network and high security requirements Some services or applications require special network hardware or strong security control, and the bare metal server provides higher flexibility and configuration freedom. Users can choose to customize hardware, network and firewall configurations to ensure data security and communication privacy.

stay Bare metal server In, the entire physical server resources (such as CPU, memory, storage, etc.) are specifically allocated to one customer, and no other customers share these resources. This type of server is usually provided by hosting service providers (such as AWS, IBM Cloud, Google Cloud, etc.), and is directly configured and allocated according to user requirements.
