There is one primary reason why large companies are migrating to AWS Azure etc that most people seem to be missing here.
It’s outsourcing the blame. This is the key to boardroom success. When something goes wrong in their own data centers, the CXOs need to shoulder the blame.
Large corporations outsource everything, including the guy who cleans the copiers, copier not working, blame the maintenance vendor.
Something went awry with the infrastructure, blame AWS
App development project went down the tubes? blame the contractors & outsourcing companies.
The Cxo comes out blameless each time
