What is Chaos Engineering?​

Chaos Engineering is about testing & increasing your system resilience.

  • Resilience Definitions on merriam-webster.com
    • the capability of a strained body to recover its size and shape after deformation caused especially by compressive stress
    • an ability to recover from or adjust easily to misfortune or change

We test our system by intentionally causing failure in parts, such as saturating the host's CPU. During the failure, we measure the time to recovery and other metrics you would want to collect.

What are Tuples?​

A Tuple is a container to hold multiple values which provide readable syntax when used appropriately. Tuples are available from C# 7 and later versions. There are two types of Tuples:

  1. Value Type
  2. Reference Type

Naturally, you might ask, what is the difference between Value Type and Reference Type?

The .NET runtime manages the memory for your application. It uses two distinct places to store data in memory, known as Stack and Heap. Any Value or Reference Type can end up either on Heap or Stack purely depending upon its usage.

Mental Model : Draw two different shapes in your head. One is fast & small, and the other is big & efficiently managed. Value Types are for small & superfast (Stack), and Reference Types for big & efficient (Heap).

I will not use Stack or Heap in rest of the post. Instead, I want you build a mental model based on two distinct memory regions.
