Why some survive to pandemics?
Slide 6
Slide 6 text
Studies suggest that viral factors
and medicines most likely
contributed to reducing the
number of deaths, however the
most likely associated with
the host's immune
system.
Slide 7
Slide 7 text
The immune system is a complex
adaptive network of cells and proteins that
defends the body against infection.
The immune system keeps a record of
every germ that has ever defeated so it can
recognise and destroy it.
Vaccines!

What is an Artificial Immune
Software System?
Slide 11
Slide 11 text
An artificial immune system
is an intelligent system that learns
to recognize relevant patterns that
have been seen previously.
Using computational techniques,
these systems are able to
construct patterns detectors and
defend the systems of similar
attacks.

Slide 12 text
An artificial immune system
is an intelligent system that
recognize and learns from faults
injected previously.
Using computational techniques,
these systems are able to
use resilience patterns to build
confidence in the system's
capability to withstand turbulence.

Slide 15
Slide 15 text
What is Chaos Engineering?
It is the discipline of experimenting failures
in production in order to reveal their
weakness and to build confidence in their
resilience capability.

What is Chaos Engineering?
is a tool that we use to build immunity in
our software systems by injecting harm, like
latency, CPU failure, or network black holes,
to find and mitigate potential weaknesses.

Why Chaos Engineering?
Because testing on DEV/STG is not
enough.
Because unpredictable events are
bound to happen ON PROD.
You need to know the unknown!

Chaos Engineering
began at Netflix
2010
Chaos Monkey was
launched
2018
A lot of resources for Chaos
Engineering.
2014
Role of Chaos Engineer
was created.

How Chaos Engineering?
Running Gamedays!
First on Call
member sees, triages, and
tries to mitigate whatever
failure the MoD has caused.
Master of Disaster
Decides the failure and
declares start of incident and
attack!!!
Team
will find and solve the issue in
less than 75% of the allocated
time. Finally they write up a
Postmortem!
Inspired in the James Burns’s work

Screws fall out all the time!!!
The world is an imperfect place.
We can not control the environment!
But we can control how to face
the virus, bacterias and the failures.
