Running memcached in self, or in a separate, droplet?
I'm thinking about using memcached and before reading https://www.digitalocean.com/community/questions/running-memcache-on-separate-droplet-worth-it I didn't think of running memcached on a separate droplet/server. Given, for example, that I had a 2GB droplet and would like to give memcached 2GB (just for keeping simple this example), what would you think of getting another 2GB droplet? and of having only one droplet but x2 capacity (4GB)? Informed advice is much appreciated. Thanks!
