The essence of both foreign and domestic virtual machines is the same. Because the distribution of networks in the world is different and the network environment in different countries is also different, the exchange of visits between countries often occurs: slow access speed, web pages can not be opened, etc. Take Hong Kong as an example. Although Hong Kong has returned to China for a long time, the network composition is basically Hong Kong's local network and overseas network, Domestic direct connection to telecommunications, China Unicom, mobile network, etc. What are the advantages of Huawei Cloud Hong Kong VM? What are the defects of other virtual machines? Today, Micron Network will study with you in detail.
After research, it is found that the micro network Virtual machine By contrast, Hua Weiyun Of Hong Kong virtual machine has the following advantages:
1、 About Huawei virtual machine lines. There is no problem that Huawei Cloud's Hong Kong virtual machine is not connected to China Telecom and China Unicom, nor will it be bothered by poor line selection.
2、 In terms of international operations, in this era of global integration and many enterprises going abroad, the international export bandwidth of Huawei Cloud Hong Kong virtual machine is sufficient, so choosing Huawei virtual machine is a good choice.
3、 There is no need for filing, and many links of submission for review are omitted. After the website built by Huawei Cloud Hong Kong VM is completed, it can be launched immediately, which greatly saves the time cost.
4、 High security and reliability: Huawei virtual machine platform has built-in ARP attack protection function and DDOS attack protection function to achieve hardware fault isolation and security protection. Huawei Cloud's Hong Kong virtual machine service supports multi-level backup and recovery, including equipment backup, system backup and application backup.
The market is volatile, and the problems of virtual machines at Hong Kong nodes occur frequently. The main defects are as follows:
In recent years, Chinese enterprises have a strong demand to expand their business in overseas markets in consumer electronics, game development, e-commerce and other fields, so it is really appropriate to take Hong Kong as the first stop to go global. However, due to the uneven quality of cloud services in the market, the number of problems and incidents related to Hong Kong hosts, computer rooms and cloud services has gradually increased, and the once sensational downtime of Hong Kong nodes still happens from time to time: a domestic cloud service provider's Hong Kong nodes are down all the time, with business interruption exceeding more than ten hours
1. Network connection affects access speed and stability. At present, Hong Kong's bandwidth can be divided into three categories: Hong Kong's local bandwidth, international bandwidth, and domestic bandwidth, while domestic users usually use the bandwidth leading to China, which can be divided into three major operators: Telecom, Unicom, and Mobile. Therefore, most domestic cloud service providers choose to bypass the Hong Kong line to the international market and then enter China to control bandwidth costs; Therefore, the speed and stability of using the Hong Kong line to access its website is an uncertain factor.
2. The data center does not have strong disaster tolerance. In case of power failure or network problems at home nodes, the local disaster backup system will immediately start the disaster backup function to provide a certain degree of cross site dynamic load balancing and automatic failover. But now, including domestic giants, most of Hong Kong is a single data center. At present, there is no local disaster preparedness system, that is, the user data of Hong Kong nodes are only backed up locally, not in other places, and most cloud service providers do not specify disaster recovery solutions.
Micronet believes that improving the quality of each virtual machine manufacturer's products is the foundation of survival. How should major domestic virtual machine manufacturers respond to policies to provide users with comprehensive and reliable cloud services in Hong Kong? In fact, it is very simple - open the international BGP link while taking into account the direct link between the telecom and the mainland, create dual link bandwidth, and improve network redundancy, just like Huawei Cloud. Internationalized BGP lines should be considered at home. Upgrading and optimizing dual link bandwidth means that cloud businesses need to spend a lot of manpower, material resources and financial resources, but most cloud businesses are unwilling to do so because the cost is too high.
For example, in order to solve the current problems such as the quality and stability of Huawei Cloud Hong Kong virtual machine network, we have invested a lot of manpower and material resources to comprehensively upgrade Huawei Cloud Hong Kong virtual machine network. The data center of Micronics Network Tiantong Hong Kong No. 2 Data Center has reached the four-star rating standard of IDC machine rooms, and the availability of 7 * 24 monitoring center and maintenance personnel has reached 99.99%. Access network lines through dynamic BGP lines, covering local, international and mainland direct lines, to achieve low latency cross network access. Primary suppliers: PCCW, Hutchinson Telecom, New World Telecom, Jiucang Telecom, Mingqitong Telecom, TraxComm, a fixed network telecommunications company under MTR, Hong Kong broadband network, and data center have multiple optical fiber redundant connection lines, and redundant POPs provide two independent data transmission lines. In terms of hardware, high-end hardware configurations such as Intel Haswell processor, super strong read/write SSD, DDR4 memory, etc. are used to ensure stable and efficient services. The policy table is updated from time to time according to the network attack address and URL to turn the defense into active, so as to prevent problems before they happen.
