For general enterprise websites, the bandwidth of the server is only 5 M~10 M, and it is not a problem to face 1 W users every day. The image website with a bandwidth of 10M may only support 100-1k people/day. If it is a VOD website, the bandwidth of the server will increase dozens of times. Especially for the VOD server, the bottleneck is bandwidth. VOD server leasing (streaming media server) is characterized by broadband. Therefore, in theory, a VOD server can be built with a dedicated bandwidth of 10 MB, but it can only support 110 people to watch videos online at the same time. If there is more, playing video will be blocked, and requests will queue up. Therefore, in general, building a VOD server requires at least 100 MB of bandwidth. So how do we choose the configuration of cloud on-demand server for our webmasters? Today, Micron Network will discuss with you. Micronet believes that the following points should be paid attention to when configuring a video cloud on-demand server:
1、 Hard disk: Video cloud on-demand servers usually occupy a considerable amount of data space. It is recommended to use servers with large hard disk capacity. If there is a budget, it is recommended to increase the budget reserve. As for the size of the hard disk, because it is a video website, the data is placed on its own hard disk. For large videos, it is recommended to be more than 1T. To ensure data security, you can use Raid10.
2、 CPU: at least E5 series from six cores to five levels or X series from five levels, with more than 8 G of memory. If the lease configurations are different, as the number of users increases, the access pressure of the video cloud on-demand server will increase, leading to the server crash.
3、 Broadband: In the case of high-definition or ultra definition, if the video cloud on-demand server has high-definition, it means that the video cloud on-demand server has high bandwidth requirements. The document transmission frequency is stable. If the number of videos and users visiting the website is not large when the video website is turned on, broadband upgrade is required. The broadband is 100 M (if 1000 people watch at the same time, the high-definition video may not be wide enough). If the bandwidth is too high, consider using 20-50 M at initial startup, and upgrade the bandwidth when increasing traffic.
When the traffic reaches 100M-200M and the bandwidth exceeds 100M-200M, consider dividing the video into two or more servers and calling through different URLs. This will reduce the load on a server.
If there are 10000 people online every day, there are about 10 people every day; To ensure that the video does not have a card, the video bit rate should be at least 300 Kbps. If 10 people are online every day, a smooth bandwidth of 0.3 * 10=3 Mbps should be provided. If your user is in the mainland, it is recommended to choose the server in Hong Kong.
Calculate the bandwidth of the VOD server:
The maximum number of online users is the real-time code rate divided by the direct bandwidth. However, in view of the fluctuation of bit rate and management requirements, the bandwidth should be kept at 20%. For example, 1 G bandwidth, 1 M code rate, CU=1 G/M * 80%=800.
The VOD server needs to consider the number of online people. If you use 100 M to play ordinary movies (600 kbps) on the VOD server, the resulting smooth VOD requires about 600/8 ≈ 80 KB/s, 100 M * 1024 K/8/80 K/, that is, 160 simultaneous links (concurrent). You can also support 10000 people online, because when you visit a web page, you only need to connect to the virtual machine for a short time to request data. These 10000 people do not necessarily need 10000 concurrent connections at the same time. In this way, the budget is 30000 yuan.
It is recommended to follow the principle of bandwidth first and performance second when configuring the VOD server. For the video cloud on-demand server of the micro network, it can consider to use 50M-100m online first in the early stage, and then upgrade the bandwidth when the bandwidth is insufficient with the increase of traffic in the later stage.
The above is the question of how to choose the configuration of the video cloud on-demand server summarized by Micronet. I believe it will be helpful to everyone. Huawei Cloud, a micro network agent, is an excellent cloud computing service provider with perfect industry solutions and excellent cloud computing technology. The self-developed pure SSD architecture ECS breaks the industry record with 50000 IOPS random read/write speed and 800 Mb/s throughput as performance indicators. The ECS elastic cloud server uses hardware devices with a pure SSD architecture. In just a few minutes, you can easily obtain and enable the cloud to meet your computing needs. Expanding the flexibility of resource use also saves you computing costs, simplifies IT operations, and enables you to pay more attention to core business innovation.
