When we rent overseas cloud servers, we often see words like "CN2 dedicated line Hong Kong cloud", "Taiwan dedicated line cloud", etc. The latency of such products is as low as 20ms, which is comparable to domestic cloud servers. Is the cloud dedicated line really that fast? What is the difference between it and ordinary lines? The so-called cloud dedicated line was born because ordinary dedicated lines can no longer fully meet the experience of market users. Let's talk about the difference between cloud dedicated lines and ordinary dedicated lines in terms of definition and application.
　　1. What is the difference between Hong Kong cloud dedicated lines and ordinary dedicated lines?
　　1. Hong Kong ordinary physical dedicated lines are physical dedicated lines whose port bandwidth resources are exclusively occupied by users. This type of physical dedicated line is used by users alone, and dedicated line users can create multiple virtual interfaces. Amateur transmission of data, voice, images, etc. is realized through ordinary interconnected dedicated lines. Resource exchange and sharing between companies and departments is realized.
　　Traditional dedicated lines are mainly used for users' LAN interconnection or fast browsing of the Internet. Users can choose speeds ranging from 64Kbps to 2Mbps according to their needs. Through interconnected dedicated lines, data, voice, images and other amateur secure transmission can be achieved: resource exchange and sharing between companies and departments can be achieved. By having a fixed and exclusive IP address, you can set up your own Mail-Server, Web-Server and other servers as needed, and you can set up a VPN business within the company through the Internet.
　　2. Hong Kong Cloud Dedicated Line (Direct Connect) is used to build a secure, high-speed, low-latency, stable and secure exclusive connection channel between the user's local data center and the VPC on the cloud. Cloud dedicated line is a dedicated line network connecting the customer's LAN and the industry cloud. It is an independent channel throughout the process and can connect to the cloud host without the Internet, so that the enterprise has a physical dedicated line private network with ultra-high security performance. Through fixed routing configuration, it can also avoid the delay instability caused by congestion or fault detours. At the same time, it can ensure high network speed, which is of great significance to customers with high confidentiality requirements such as banks and financial institutions.
　　Compared with ordinary dedicated lines, Hong Kong Cloud Dedicated Line has the following three advantages: high availability, high security and elastic configuration.
　　Under the entire framework of Hong Kong Cloud Private Line, network application services can be switched very smoothly. The reason why enterprises use cloud private line is that cloud private line can provide enterprises with better help and better network usage environment. In addition, you should also find a reliable private line provider when applying for cloud private line.
　　Second, which one is better, Hong Kong cloud private line or ordinary private line?
　　1) High availability: Compared with general private lines and traditional server vendors, cloud private line will adopt more stringent IDC standards, server access standards and operation standards to ensure the high availability of the entire cloud computing infrastructure, data reliability and high availability of cloud servers. Based on this, each geographical area provided by cloud private line has multiple availability zones. If you need higher availability, you can use the multi-availability zones of cloud private line to build your own primary and standby services or dual-active services. In the financial field, with a solution of two locations and three centers, you can also establish higher availability services through multi-regional and multi-purpose areas. These include disaster recovery, backup and other services.
　　2) Low price: Since the price of HKT4 Hong Kong cloud private line is cheaper than the physical private line, it is beneficial to enterprises, so cloud private line is increasingly favored by corporate offices.
　　3) High efficiency: In terms of operation, cloud dedicated lines are simple to operate, and automatic detection and protection are achieved, which greatly improves the operation efficiency. At the same time, cloud web pages have high anti-tampering performance and low system resource occupancy rate.
　　4) High quality: In the early stage, cloud dedicated lines mainly come from industry cloud operators, such as Tianyi Cloud, Tencent Cloud, Huawei Cloud, etc. Cloud dedicated lines provide safe and reliable dedicated line access channels for internal cloud resources of enterprises, such as using MSTP,  but it is not easy to establish this real dedicated line, which involves the cooperation of traditional operators in many aspects, so it lacks flexibility in resource coordination and bandwidth adjustment.
　　Cloud operators such as AWS and BAT have proposed the response ideas and practices of cloud dedicated lines to solve the core problems in scenarios such as data migration, data synchronization, and data disaster recovery. By improving the flexibility and innovation at the SaaS application level, they have attracted a large number of enterprise users. In addition, while preventing the loss of government and enterprise customers, traditional operators can not only improve flexibility, but also improve their competitiveness in terms of lines, thereby making up for the lack of development capabilities at the SAAS level.
　　4) Multiple scenarios: Cloud dedicated line is displayed in multiple scenarios, and remote secure collaborative office services are held in a convenient audio and video conference mode, greatly improving the service efficiency of cloud dedicated line digital office. Cloud video + and conference management and control functions are powerful, easy to interact and collaborate, and fully support various office collaboration scenarios, greatly improving collaboration efficiency.
　　The basic functions of cloud dedicated line help users build virtual private clouds, support layer 2 and layer 3 network capabilities, and have firewall load balancing, DDoS snapshot backup and other functions. The reason why enterprises use cloud dedicated line is that cloud dedicated line can provide enterprises with better help and a better network usage environment, can back up and roll back data on cloud servers, improve security, and reduce the difficulty of snapshot management.stable and high-speed network connection.
　　JTTI Hong Kong cloud dedicated line products provide high-speed, secure and unique networks and respond quickly by building high-speed, low-latency, stable and secure exclusive connection channels, thereby enhancing the competitive advantage of enterprises in the industry.
