Name a time Azure has gone down leaving its customrs in a lerch.
FYI, It has happened just this morning.
“Summary of Impact: Starting at 04:39 UTC on 19 Nov 2018 customers in Europe, Asia-Pacific and the Americas regions may experience difficulties signing into Azure resources, such as Azure Active Directory, when Multi-Factor Authentication is required by policy.”
While this outage may not create a large issue, but what would happen if your customer was NYSE, NASDAQ or the CBOE? Ummm, does the stock market come to a hault because of an authentication change?
This is just some of the reasons companies may not go to the cloud or at least invest heavily in the cloud.
