> nuke the VM once a year and re-provision otherwise you have to maintain the OS, do cleanup etc
That is really interesting. What are you using to re-setup your entire infrastructure after purging a VM? How do you manage the down time between one vm purge to setting up the next one.
I would love to know, going beyond the VPS what is your total
infrastructure + maintenance cost.
I set things up again on the new VM manually. I have a runbook for it, usually takes me 30 mins or less.
To not have any downtime I keep the old VM up and attach a new public IP to the new VM. I then update the DNS records and after a while when the new IP is mapped to my domain I then stop the old VM.
Costs:
Managed Mongodb cluster: $9 but I share it between multiple side projects so let's say $3
API health checks - free! I use digital ocean and fresh ping
Service Desk - free! I use Jira
DNS: Usually $0.3
DB backups: within the free tier on both cloud providers. I have it set to only keep the last x backups so this should always be free
Cron job to run the backup: I have a serverless function for this, still within the free tier
DNS - I use GCP as the domain was purchased with domains.google because I get free email addresses which I can receive and reply to from my personal gmail (e.g. support@saasapp.com). I'm not 100% sure if this setup will work with another DNS provider.
Docker Image - Since I'm running this most of the operation on AWS I use ECR
