I have added this site to Cloudflare with a free account. This allowed(required) me to move the DNS service to Cloudflare DSN and remove the Google DNS that Google charges a few cents a month for. It also add the benefit of caching this site for users not close to my server. So now on the Google Cloud platform, I have the minimum footprint of a single free tier server and a public static IP address.
I did make the performance tuning tweaks to mpm_prefork.conf to keep the utilization of the server from spiking into the range where Google will recommend an upgrade. As long a no one actually visits this blog, I should be able to stay in the free tier.
