In this article posted by DO on Twitter, a startup explained how it uses Digital Ocean in general terms. It talks about setting up 5 different boxes ($5 per month each) and one $20 box per month for redis. https://follower.io/blog/how-we-saved-3-5k-a-year?utm_source=rubyflow Just curious 1) In what types of situations would you set up multiple smaller boxes (5 at $5 per month) rather than combining them into one bigger box? 2) why set up Redis on one big box? Can Redis be installed and used on the same box as an application? I've installed Redis and Memcache on one $5 box with nginx and unicorn server to host a Rails application. I'm not sure if I'm putting too much stuff on one droplet. Any comment?
