[new function!] How anycast CLB supports multi location & dynamically accelerated load balancing services and high-speed Internet forwarding!

2022-06-24 01:49:00 【TCS-F】

Load balancing supports the creation of Anycast Load balancing （ Hereinafter also called Anycast CLB） example ,Anycast CLB yes Load balancing services that support dynamic acceleration in multiple locations ,CLB Of VIP Will be published in multiple regions , The client accesses the nearest POP Access point , Forward to the cloud server through the high-speed Internet of Tencent cloud data center . Anycast CLB It can realize the quality optimization of network transmission and the nearest access of multiple entrances , Reduce jitter of network transmission 、 Packet loss , Finally, improve the service quality of Cloud Applications , Expand the scope of services , Streamline back-end deployment . This function is under internal test , If you want to use , Please submit Internal test application .

What is? Anycast

Anycast Also known as Anycast or broadcast , Refer to One IP Publish routes in multiple regions at the same time , The routing algorithm will reduce the user traffic Send to the nearest router . Anycast CLB There are the following advantages ：

Low latency Anycast CLB use Anycast The way to put VIP Publish to multiple regions at the same time , The request packet will reach the optimal according to the transmission protocol VIP Release region , Give priority to Tencent cloud , adopt Tencent intranet to cloud server , To avoid the Public network congestion , Reduce the time delay .
Reduce jitter and packet loss The transmission performance of the public network link is unstable , Such as North South issues 、 Cross border issues, etc , It will cause network jitter and packet loss , Affect the service experience . and Anycast CLB The transmission performance is stable , it Connect the client request to the nearest Tencent cloud , Cross region transmission through the intranet dedicated line of Tencent cloud , The problem of public network jitter and packet loss is solved .
Highly reliable Public network transmission is an unreliable transmission , The operator's line is interrupted , Make the service inaccessible , General users can only wait for recovery . Use Anycast CLB after , Tencent cloud intranet 、 Operator network 、 Tencent cloud POP The access point can realize network multi-path and multi entry , Shield single area and single line faults , Improve network stability .
Simplify deployment Customers are scattered in many places and need nearby access services , Multiple machines need to be deployed and configured DNS Load balancing , And in different regions IP Different , Cumbersome deployment . Use Anycast CLB after , stay IP The level converges the regional attribute , There is no need to configure every region IP, And the back end maintains a set of logic , Requests from various regions are directly accelerated to the back-end machines through the intranet .

Anycast CLB framework

Anycast CLB The architecture of is shown in the figure below .

Anycast CLB Of VIP Will be published in multiple regions , The client accesses the nearest POP Access point , Quickly forward the access traffic to the ECS through the Tencent cloud intranet .

Anycast Publishing domain

Anycast The publishing domain is acceleration IP Where the address is published , namely Anycast CLB Of VIP Issued by POP Access point , The client will access the nearest POP spot . at present Anycast CLB Support simultaneous publishing in ： Beijing 、 Shanghai 、 Guangzhou 、 Hong Kong 、 Toronto 、 Silicon valley 、 Frankfurt 、 Virginia 、 Moscow 、 Singapore 、 Seoul 、 mumbai 、 Bangkok and Tokyo .

Anycast CLB The region

It is consistent with the regional concept of general load balancing ,Anycast CLB The territory is to buy Anycast CLB When you choose the region , It also refers to the region where the backend ECS is located . at present Anycast CLB It has covered most areas .

China ： Beijing 、 Shanghai 、 Guangzhou 、 Hong Kong .
Europe and the United States ： Toronto 、 Silicon valley 、 Frankfurt 、 Virginia 、 Moscow .
Southeast Asia ： Singapore 、 Seoul 、 mumbai 、 Bangkok 、 Tokyo .
Anycast CLB from Anycast EIP Bind intranet load balancing to provide Anycast Ability .

Anycast CLB Use scenarios

Serve more than one place

Game customers want players from multiple regions to be in the same zone （ Or the branches of the enterprise in different places want to use the same data center ）, You can deploy back-end services in one region （ Such as Guangzhou ）, Buy one in Guangzhou Anycast CLB, Select the publishing domain as required , Multiple players （ Or employees ） Connect to the nearest , And access the same set of back-end services .

Game acceleration

Anycast CLB It is also widely used in game acceleration , The game requests to access Tencent cloud nearby , Reach the game server through the intranet of Tencent cloud , Greatly shorten the public network path , Reduced latency 、 shake 、 The occurrence of packet loss and other problems . Compared with the traditional acceleration , The portal does not need to deploy additional traffic receiving devices , And there is no need to distinguish regions , To simplify the DNS Deploy .

Operation guide

Prerequisite

This function is under internal test , Please make sure that your Internal test application Passed .

Operation steps

Sign in ECS console .
In the left navigation bar , single click Elastic public network IP, Get into “ Elastic public network IP” Manage Pages .
single click apply , In the box ,IP Address type selection Speed up IP, single click determine that will do .

Sign in Load balancing console , Select an intranet load balancer （ Traditional intranet load balancing is not supported ）, Click... Under the action bar more > Binding acceleration IP.

Intranet load balancing binding acceleration IP after , This load balancing provides Anycast Load balancing services . For more load balancing configurations, see Load balancing listener Overview .
