Because none of these remove complexity. They relocate it.</p> <p>Replication. Multiple copies, one writer. You buy availability and read throughput. You now own replication lag, and the ticket from a user who saved something and didn&rsquo;t see it on refresh.</p> <p>Sharding. Split the data across databases. You buy headroom. You now own a shard key that you chose at the exact moment you knew least about your traffic.</p>
