I hear multiple people state that MPLS is dead, and moving to DIA and/or SD-WAN is the way to go. We have multiple offices within the same region of the U.S. and our ISP handles our layer 3 out to the internet via their centralized datacenter (DC). We recently renewed with our ISP and the MPLS quote actually came in lower than their DIA quote (and against other carriers). Maybe they thought it was easier to not re-architect our network?
That being said, I am attempting to analyze why getting rid of MPLS would be better. We have a single pipe out to the internet, so implementing one firewall at the WAN point would be easier than having a firewall at each office location. Access to cloud services seems to be non-latent. When employees attempt to access internal network shares via VPN, there is no high latency occurring either.
MPLS seems to work out better for us...... convince me otherwise?
