Thanks for this excellent guide! I have been thinking about trying to become a witness. This guide will really help!

One question regarding the servers. On OVC, they have options for "Dedicated" and "Cloud". The cloud looks cheaper. Do you have any tips/suggestions on which server package is good to choose? (When I searched, the SP-30 under 'RAM Instances' with some additional HD space added in seems like the most affordable option to meet all the requiremets.)
