Let us start with High Availability. Whenever we hear the term High Availability we tend to think, an architecture that is highly available, scalable and cannot fail. Well, the first two points might be right, but last part "Fail"  is where we need pay bit more attention. Lets see the difference. A High Availability: Architecture is actually prone to failures. What the term "High Availability" implies is an Architecture that intends to provide a maximum uptime.
