Both ECS and physical server are data storage media, so the difference between ECS and physical server today is that different enterprises should choose ECS or physical server. Let's explain below.
What is ECS?
ECS BCC is a cloud computing service based on virtualization and distributed cluster technology that Baidu has accumulated for many years. BCC supports flexible expansion, rich and flexible minute billing mode, and provides you with high-performance cloud servers with the highest cost performance ratio in the industry through value-added services such as images, snapshots, and cloud security. What is a physical server?
The physical server refers to an independent server, that is, a physically independent server. The physical server consists of processors, hard disks, memory, system buses, etc. Similar to the general computer architecture. However, because it needs to provide highly reliable services, it needs higher processing power, stability, reliability, security, scalability, manageability, etc. What is the difference between ECS and physical servers?
Different configurations
The configuration of ECS includes hard disk, memory, CPU, operating system, solid state disk, etc. Therefore, the price will vary depending on the ECS configuration. If the purchased ECS is on the backbone node, its access speed will be faster than that of ordinary nodes. The cost of general hard disk and SSD solid state disk is different, but it does not need to make several accessories with high distribution status, which can be configured according to the actual situation of the website. For example, those with high memory requirements can spend more money on memory, while others can choose mid-range ones.
Different Bandwidth
The bandwidth leased by ECS is mainly divided into shared bandwidth and exclusive bandwidth. The exclusive bandwidth means that users can use the bandwidth of the provider alone, while sharing is shared by multiple users. Of course, this bandwidth will cause slow and unstable network speed. The price of shared bandwidth is low and the stability is poor. The exclusive bandwidth is more expensive and stable. Due to different lines, the bandwidth costs of China Telecom Unicom single line, China Telecom Unicom double line and BGP multi line are also different.
Distributed Storage
The difference between ECS and ordinary servers lies in the storage mode. The cloud server uses distributed storage, such as the ceph distributed storage system used by the knowledge cloud, which is characterized by good scalability, high performance, and high reliability. It can realize real-time multi copy disaster recovery without single point of failure, effectively avoid various failures, support elastic expansion of storage resources, and enable ECS to have hot migration and other functions. However, ordinary servers cannot realize distributed storage. Once the hardware fails, data security will face serious risks of loss, damage and even irrecoverability. Therefore, enterprises usually deploy RAID10 array security policies, but this requires high costs and hardware purchase costs, increasing the financial burden of the company.
The above is about the difference between "ECS and physical server?" As the representative of servers in the new era, ECS will increasingly appear in our lives and gradually replace other server people ".
