Save Yourself From a Disaster
Save Yourself From a Disaster

About the Book
What can we learn from the latest major cloud incident (ie. burning OVH datacenter)? Do not put all your eggs in one basket!
The only certain thing is that it's not a matter of IF there'll be a disaster but rather WHEN so better be not caught off guard.
