It is important to note that the always free tier is not set up as “1 instance” it is set up as a number of instance hours (or instance months, or ip-address-months). So, you could run 3 instances concurrently for a third of a month as well (as long as they each only had no more than a 30GB disk attached each — the limit of total disk usage is 30GB-months).

So take advantage of this to save money by stopping and starting Compute Engine instances on schedule. reddit search on cloud scheduling
