Scale all the things: 'Setup a caching layer (Memcached, Redis, Varish)'...if only it was just that easy. Prep for scaling should be something like; 1. testing to see when you'll need to 2. monitoring so you know when 3. planning before you reach date / time from #2 how you'll do it 4. implement 5. test you've done #4 properly 6. release 7. repeat the whole process Work out a methodical way that makes sense. "Setup a caching layer" is not that.
