Sir. Haxalot

I’ve always been self hosting a lot but recently I’ve started to move some external things

• Domain management from Cloudflare/AWS to OVH.
• DNS and CDN from AWS/Cloudflare to BummyCDN
• E-mail Gateway from AWS SES to a mail server on Hetzner (pending)
• Considering to self host email to get off Googlw Workspace (free), but Im not sure that is a commitment I want to make.

And of course trying to go from Reddit to the Fediverse

Indeed and the only thing I have ever seen a larger company running is Microsoft Exchange, but MS is actively pushing to cloud here. I also know a few people who work with Exchange and they kind of hate it.

The option has the traditional open source stack I guess with Postfix, Dovecot, Spamassassin, some Webmail client, and then you have to make sure that SPF, DMARC, and DKIM signing works… It becomes a lot so I understand why none willingly wants to deal with this. That said there are some more modern alternatives like Stalwart mail server that combines the first three services into one and something I’m considering to try out.

I feel it’s very important to point out that specifically email is one of the most common things to outsource. Hosting your own email is simply one of the harder things to run on your own, having to deal with anti-spam measures, IP reputation tracking and the risk of other providers blocking you if one of your users are compromised and used to send spam.

My point being that yes, you are somewhat likely to use other Cloud products but it’s not a good indicator for how dependent the core business is on cloud providers.

Tracking specifically email is probably the best thing if your goal is to create an infographic where the dependence numbers are as high as possible though.
