On availability aspects of microservices

This post is in response to the WeekendDevPuzzle of 2022-01-29, which has submissions from people who chose to share their perspectives on the puzzle. I'll be linking this post to this Twitter thread, to avoid polluting the original one.

Motivation for today's topic

Unlike the usual peel the onion kind of topics, this one focuses more on how we think & our mental models of architectural decisions. But there's more.

Over the past 15 yrs, programming has become extremely accessible. While that's undoubtedly a good thing, it's become much easier to just rely on best practice, with or without context. Today's puzzle was designed to bring to the discussion table, that context, albeit in a super simplified fashion.

Dissecting the puzzle

Let's dissect the question, and bring out the core elements of it.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

// Stack - Object oriented implementation using arrays
#include <iostream>
using namespace std;
#define MAX_SIZE 101 

class Stack
{
private:
  int A[MAX_SIZE];  // array to store the stack
	int top;   // variable to mark the top index of stack.
