<h1>Conclusion</h1>
<h2 id="conclusion">Conclusion</h2>
<h1 id="conclusion">Conclusion</h1>
<p>Armed with these principles, we hope the course will give a fresh perspective to design software systems. It might be over engineering to get all this on day zero. But some are really important from day 0 like eliminating single points of failure, making scalable services by just increasing replicas. As a bottleneck is reached, we can split code by services, shard data to scale. As the organisation matures, bringing in <a href="https://en.wikipedia.org/wiki/Chaos_engineering">chaos engineering</a> to measure how systems react to failure will help in designing robust software systems.</p>

<p>Failures are not avoidable in any system and will happen all the time, hence we need to build systems that can tolerate failures or recover from them.</p>
