UseCase
Suppose a business has two branches, one in Ho Chi Minh City and one in Hanoi. The system already has a VPC in the Ho Chi Minh region and a VPC in the Hanoi region. To allow these two branches to communicate with each other through a private network, the Cross Connect connection will link the VPCs of the two branches in Ho Chi Minh and Hanoi.
Implementation Solution:
Each branch has its own VPC (if not, at least one VPC must be created at each branch);
Create a Cross Connect connection between Ho Chi Minh and Hanoi;
Select and purchase the appropriate bandwidth package for the connection between the two regions;
Link the two VPCs through the Cross Connect connection;
Set up communication between the two VPCs via Cross Connect.
Advantages:
Easy to use: With a few simple steps, businesses can establish inter-regional connections between VPCs;
High performance: Cross Connect leverages the global network infrastructure of VNG Cloud to provide high-quality, low-latency connections with bandwidth that can be flexibly adjusted to meet changing business needs.
Limitations:
A Cross Connect connection cannot be created between VPCs with overlapping CIDR blocks;
Bandwidth adjustment for connections between regions is limited depending on the region connection.
