When MPLS networks came on the scene, the internet did not have the global backbone in place the way it is today. Packet loss and congestion were common place. And the T1 or E1 was considered a “big pipe” by many. The global internet cable infrastructure is now enormous. You can see that internet transit costs, which are the backbone costs of the internet, have gone down every year.
What do lower internet price mean? You can have a lot of bandwidth on the public internet without paying a fortune! With the exception of certain areas such as China, Africa, Bolivia and a few other countries, you will find that using the internet, especially with two connections and SD-WAN, will provide better performance than an MPLS network.
