Demonstration of High Availability Techniques
Understanding what high availability is and some of the key goals for achieving higher levels of reliability will help you design your IOT solutions for greater reliability. As you learned in the previous chapter, it takes a bit of work to achieve these goals, but the payoff for a modest amount of work is well worth it should your solution expand beyond a set of discrete nodes.
However, knowing the concepts is only part of the solution. You also need to see examples of how some of these techniques are manifested. For example, how do you detect and recover from a data collector node failure, ...
