[Tencent cloud load balancing CLB] cross region binding 2.0 (new version) idc-ip best practices!

Load balancing （CLB） Support cloud networking , Bind ECS across regions , Allow customers to select the regions of multiple backend ECs , Span VPC、 Bind backend ECS across regions ,（ Support IDC Offline IP）. At present, the function is in the internal test stage , If you need to experience this feature , For domestic cross region binding, please go through Internal test application , For overseas cross region binding, please Business application .

In particular ： The cross region interconnected bound ECS does not support traditional load balancing

• This function is only supported by standard account types . If you are unable to determine the account type , Please see the Determine the account type .
• Cross region binding 2.0 And hybrid cloud deployment , I won't support it The security group is released by default , Please put... On the back-end server Client IP And service ports .

Application scenarios

1. Satisfy P2P In the game business , The scene of serving multiple places . The customer back-end service cluster is in Guangzhou , The customer hopes to be in Shanghai 、 Beijing and other places have established CLB, Bind the same Guangzhou backend service cluster . Accelerate the game 、 The function of flow convergence , Effectively ensure data transmission quality , Reduce delay .
2. Meet the financial business payment 、 Scenarios such as order payment , Effectively ensure the data transmission quality of key services , Ensure data consistency .

The difference with the old cross region binding

Contrast item	Cross region binding 2.0（ new edition ）	Cross region binding 1.0（ Old edition ）
Whether it supports binding services in multiple regions at the same time	Support ： New cross regional binding CLB Support binding multiple regions at the same time CVM. For example, in Beijing CLB It can bind Beijing and Shanghai at the same time CVM.	I won't support it ： Old cross region binding CLB Only one region can be bound CVM. For example, in Beijing CLB Can be bound to Shanghai CVM, But in Beijing CLB Cannot bind Beijing and Shanghai at the same time CVM.
Whether it supports changing back to not cross domain after cross domain	Support ： The new cross region binding supports changing back to the original same region binding .	I won't support it ： After modifying the region attribute of the backend instance in the previous version of cross region binding , Such as the region and CLB Different regions , You cannot change back to the original same region binding .
Support CLB type	Support public network CLB And the Internet CLB.	Support public network CLB.
CVM On release CLB Whether to unbind automatically	Automatically unbind when binding in the same region ：CLB Bound to the same region CVM, If so CVM Be released , be CLB Will be automatically associated with the CVM Unbundling . Automatically unbind when binding across regions ：CLB Cross region binding CVM, If so CVM Be released , be CLB Will not be automatically released from the CVM Binding relationship of , Manual unbinding is required .	Automatically unbind when binding in the same region ：CLB Bound to the same region CVM, If so CVM Be released , be CLB Will be automatically associated with the CVM Unbundling . Automatically unbind when binding across regions ：CLB Cross region binding CVM, If so CVM Be released , be CLB Will be automatically associated with the CVM Unbundling .
Whether the price is favorable	Billing through cloud networking , Be able to carry out refined cost accounting , Lower price .	Japan 95 charging .
