Can I Deploy an Application on the Cloud and a Database in an On-premises Data Center and Connect Them Through a VPN?
Yes.
A VPN connects a VPC and an on-premises data center.
After a VPN is set up, service traffic can be transmitted between the VPC and on-premises data center. For an application server on the cloud, access to an on-premises database is logically the same as access to other hosts in the same LAN. Given this, it is feasible to use a VPN to connect an application on the cloud to a database in an on-premises data center.
This is a typical IPsec VPN scenario.
Additionally, there are no limitations on the service initiator. That is, service requests can be initiated from the cloud or the on-premises data center.
- After a VPN is set up, check the network latency and packet loss rate to ensure smooth service running.
- It is recommended that you run the ping command to check the packet loss and network latency details.
