Cloud line from the user local network to network operating network to network within the cloud, end-to-end through traffic forwarding, users of network user management, network operators is operator management, network of cloud is cloud management,
two typical application scenario
1. The enterprise data center hybrid cloud architecture
For the Banks, the state-owned enterprises, such as confidentiality of customer is important, because safety and control, not all enterprise information should be placed in the public cloud, can use a hybrid cloud architectures, keep the key data in the local data center, other data in the cloud,
2. Different disaster
Establish a backup system in different locations, through special line service to connect, at the time of the disaster, can make the system more reliable quickly returned to normal,
The five stages of development
Cloud era special business development mainly has five stages,
The first stage is the cloud line,
The second stage is the DCI lines, including the DCI line across the region and the DCI between AZ special line, the third stage for cloudy cloudy point-to-point line and special network line,
Fourth stage for SDN network line and cloudy across the metropolitan area network lines,
Stage 5 special network line for cloudy across the region and to support network dedicated online open,
The difference between cloud line and VPN business
1. The price and the stability of
Commonly used Internet virtual proprietary network, or VPN, price is low cloud line, but on the quality of the public security than the shuttle, ShiYanGao, not a cloud line security, cloud line relatively low latency, service quality is stable, but the price is high,
2. Open the time
On the opening time, because of limited by physical line deployment, operators of line resources, so cloud line deployment time is longer than the VPN, in this case, there are an order of magnitude, VPN if Internet resources on both sides, is basically out-of-the-box, configured on both sides, can communication negotiations,
Cloud line is usually the data center and public cloud VPC docking, this time is limited by physical link, operators to check resources, to do physical line, under normal circumstances, operators commitment of time, generally require at least 20 working days, opening online configuration of the cloud line, general level is also a day, now in to get the line configuration information, and physical line after docking, can be completed in one day the line configuration through,
cloud line FAQ
Q: how do clouds line configuration is complete test virtual machine to the shuttle gateway connectivity?
A: the cloud line under the default configuration, virtual machine can't ping line connecting the gateway and offline data center network segment,
If you need to test, need to line under the gateway and cloud docking segment (i.e., the remote gateway and the client gateway's subnet) added into the far terminal network of the virtual interface,
Q: how to monitor cloud line network quality?
A: cloud line plug-in is used to detect the cloud line plug-in end-to-end network quality, the main two indicators include network latency and packet loss rate,
Cloud line plug-in is divided into two kinds:
Dc - nqa - the collector: used to monitor automation line, detect the far terminal network delay and packet loss rate,
History - dc - nqa - the collector: used to monitor the manual line, detect the far terminal network delay and packet loss rate,
Q: the user can cloud the same VPC docking multiple physical connection?
A: you can create multiple virtual interfaces, each virtual interface to select different physical connection, select the same virtual gateway at the same time, the virtual gateway and VPC one-to-one correspondence,
