Network Topology Reorganization

When there would no longer be any server in Mission Viejo and Phoenix, we can save operational costs by cancelling the MPLS service lines. We can set up site-to-site VPN connections between our office routers similar to the topology between of site-to-site VPN between our offices and AWS networks.

It is highly recommended that we add another Internet line as a load-balance and fail-over to our existing connection to the Internet for the Irvine headquarter location. There are many commercial grade dual-wan routers on the market to serve this purpose.

MPLS has the advantage of delivering a slightly lower latency, while VPN has the advantage of being extremely cost effective. If we have a bandwidth above 5Mb/s being dedicated for VPN voice traffic, while having a second line for general Internet, there shall be virtually no noticeable performance difference to MPLS.
