I don’t think that’s actually possible. Because each business is completely different. Depends on how frequent back-ups are. How many domains you have.
It breaks down to this:
5.00 Lightsail Server (as long as you stick within it’s parameters it’s 5.00)
Route53 is included in Lightsail (make sure you do it in Lightsail) Excludng registering your domain and that depends on the TLD you choose.
S3 comes with a free tier. No way to estimate this. This is dependent on each individual user.
Snapshot again is on an individual base. Depends how often you do snapshots and how often you delete them. I don’t use snapshots for anything.
I have a server for WordPress that does a backup of WP and the database every 4 hours (The only reason I do 4 hours is our website has high traffic. When we started it was once a day) to S3. I have a lifecycle policy in place that deletes the back-up every 7 days. I have a lifecycle policy in place that moves one back-up every week to Glacier for a “just-in-case” scenario. Hidden malware, hacked, etc and have to go back to find where it came from.
MIAB that uses the MAIB backup feature to S3.
ALGO VPN Server
Asterisk PBX Server. I use the backup feature that comes with PBX In A Flash with the same scenario as WordPress server
And instance that is just a MySQL server.
I just have instances that have all the server software installed and turned off. If something fails. I just turn the old server off. Turn on the new. Run the restore feature. And I’m back online.
My bill last month was 46.36 however, my WordPress server is 20.00 a month server because we use Matomo for analytics, YOURLS instead of Bit.ly, and our CRM is built into WordPress and needs more power.
For Algo I use the 3.50 server. That’s all that is really needed for Algo.
Sorry I couldn’t be more helpful.
