If you are tiny and looking to stay tiny…you have my heartfelt blessing.
If you are tiny and looking to grow, keep it simple, focus on building something great, and hope that one day you are •lucky• enough to have so many users that you need to rearchitect for scalability.
Honestly, more often than not, that moment of needing to rearchitect for scalability is a sign of •success•: somebody chose the tools that were appropriate to being small, and they succeeded.
