Hi Mustafa,

Instance HA (as in protection against hardware failure) is not a feature 
of UEC, and more generally is not a feature of cloud computing. The 
correct way to think about this problem, is how to architect your 
software such that an instance failing becomes "not important", causes 
no data loss or service interruption
