You are asked to design a simple service 
and provide 99.99 % availability. What would you do differently to provide 99.999%?
I am organizing a guest event to help everyone gain some practical understanding on how to design a 99.999% service. We have a guest speaker, an ex Microsoft who has maintained and managed multiple such tier-1 services.
Event Date: June 6th
Timing : 6:00 pm - 7:00 pm PST
cost : $100
