Sure - the &quot;race to the bottom&quot; for hosting prices inevitably means there&#x27;s going to be options like GoDaddy offering &quot;a year&#x27;s worth of webhosting for $5&quot; which clusters 400 WordPress and Drupal sites onto a single RaspberryPi or similar, but you don&#x27;t _have_ to go there.<p>I can understand if you&#x27;re an open source developer who gets paid in Uzbeki Som or Nigerian Naira, the calculation of &quot;do I spend a day or two putting caching in place&quot; versus &quot;do I spend an extra $50 or $100 per year on hosting&quot; might lean very much the other way, but I suspect for the vast majority of HN readers, the prudent approach is &quot;pay a hundred or two dollars a year for hosting before bothering to implement complex caching strategies&quot;.
