"Five Nines" - Myth or Reality?!?

Five Nines... or 99.999% High Availability.  Is this reachable? And how do you calculate High Availability?  These are the questions we pondered here at OSSera as we looked at the value of the architecture we have before us.  It is amazing to learn that our executive staff has not only a background in pioneering software architecture but also have a background in teaching probability.

High Availability, the Probability of Availability, can be a pretty dry topic unless you are responsible for making sure your OSS is up 99.999% of the time and we aim to make sure you can reach this goal.  To "jazz up" this topic take a moment to view this latest video in our library which will hopefully simplify and illustrate what the OSSera Unified Services Frameworx can do for you.

Note the example:

p(ABCD) = p(A) * p(B) * p(C) * p(D)

p(A,B,C) = 0.1 (is a hypothetical example of the probability of this server going down)

p(D) = 0.01 hypothetically

P(ABCD) = 0.1 * 0.1 * 0.1 * 0.01 = 0.00001

This means we can reach 99.999%  "Five Nines" High Availability with 4 servers... however this can be improved if each server has a higher availability.

The last slide in the video highlights that both Oracle and MySQL support clustering which further helps in the High Availability goal.  But rest assured the OSSera architecture is multi-threaded and runs in both an Asymmetrical and Symmetrical Multiprocessing configuration to maximize your OSS availability.

OSSera's platform is not bound to a single CPU or single server but because of its multi-threaded architecture it distributes processing across all available CPU's and servers.  By adding CPU's and servers the solution not only increases in High Availability but also in scalability and performance throughput as the load can be balanced across the added processing capacity.

We hope this helps explain one of the many important benefits of OSSera's architecture.
