Azure has only 99.95% uptime (Four 9s is standard, 6 is my personal minimum). The Azure cloud also has an incomplete UI, and a large portion of its services are either NOT theirs ( hosted in their “Marketplace”), or they are a part of their API which is constantly changing/invalidating infrastructure as code, such as Terraform.
However, Gartner says the following about Azure:
“Gartner finds fault with some of the platform’s imperfections. “While Microsoft Azure is an enterprise-ready platform, Gartner clients report that the service experience feels less enterprise-ready than they expected, given Microsoft’s long history as an enterprise vendor,” it said. “Customers cite issues with technical support, documentation, training and breadth of the ISV partner ecosystem.”
