As the title states, is the poweredge T30 good enough for a small city as we are looking for the cheaper option or do you think it would cause problems in the long run, i also saw on a post from a while ago that someone said it would work on a vps with dualcore and 2GH processor and 8 ram but we would buy it with 32 just in case, thanks for your time :).
Here you have the link to the recommended specifications:
Remember, this is a general recommendation.
The correct thing would be to monitor the performance of the servers and customize the characteristics of the hardware according to the traffic.
As an example: With a population of 243,000, assuming you will use it less than 10% at first, 16 Gigabytes of RAM and a dual core may be enough.
To monitor performance an option is Newrelic. Newrelic has a free plan that is more than enough to see the capacity the server is using.
Newrelic is already partially integrated with CONSUL. It should be enough to add the token of the Newrelic account to an attribute newrelic_key in the production block of secrets.yml.
