It sounds long ago, but this post is still so relevant for anyone not yet bringing operations and development close together. And for those who did:
[WayBack] Nick Craver – Stack Overflow: How We Do Deployment – 2016 Edition
The relevance is why Nick repeated it in 2018 in a response to a @ThePracticalDev discussion right after the first Falcon Heavy deployment, and why I repeat it now.

Still a very insightful read: [WayBack] Swap and Memory Pressure: How Developers think to how Operations people think – The Isoblog.
I totally agree with the view Kristian Köhntopp presents which I usually call “fail early, fail hard, fail clearly”.

A long time ago, I named a tool Cerberus after the mythical multi-headed dog that guards the gates of the Underworld, as it was to inspect client systems configurations to prevent they would enter a bad state.
Since I need a multi-headed tool later on, below are some links on multi-headed (Polycephaly – Wikipedia) creatures to give me inspiration.
Some of them are centered around war, others around hell, are dragons or monsters, and a few are guardians. Later I will try to put a classification in a table or so.
The idea is to replace my current Apache TLS offloading (that uses letsencrypt/certbot for the certificates) with something else like an nginx one, and maybe even make the internal part TLS too (so it becomes TLS upstreaming) so these will come in useful too:
Instead of nginx, HAproxy might be a an option too, especially as it understands TCP traffic other than http much better than nginx:
This means I should first look into nginx vs haproxy – Google Search, for instance these posts:

Since I will likely need something like this one day: [WayBack] GitHub – Nike-Inc/gimme-aws-creds: A CLI that utilizes Okta IdP via SAML to acquire temporary AWS credentials
I think I got this via Kristian Köhntopp a while ago.

Always use UTC on your servers, as [WayBack] Yeller – The Worst Server Setup Mistake You Can Make: Setting the timezone to anything other than UTC.
Many many reasons. For me the number 1 is sanity.

The answer to the meme on the right:
If you are having problems deploying on a Friday, you will have them at any time of the week. Your processes are broken.
Source: [WayBack] Friday Deploys, and other harmful BOFH memes – The Isoblog.
via: [WayBack] Friday Deploys and other harmful BOFH memes – they need to die in a fire… – Kristian Köhntopp – Google+
Kristian argues that people finding the meme funny should get fired.
I still find it funny. Both in a way that I’m surprised so many BOFH are still there, as well as being happy that on many occasions I’ve helped making this a thing of the past or at least make organisations aware of the deployment risks and how to cope with them.
Do I need to change? Definitely: life is all about learning new things every day and change because of that.
Do I need go get out of a job or a new job? Likely at some point because life is all about change. Hopefully I’ve learned enough by then to find another gig where – in addition to applying my tech skills – I can spread awareness and knowledge. And learn new things. Did I tell about life is all about learning?
