Mix is absolutely awesome. One of the most carefully organized open source projects that I've seen. Some years ago I made a Mixxx demo video with a DYI "integrated controller". It demos Linux boot to Mixxx, touch screen, beat

True story ^^^^^ Add to this, that you can have outages due to operational complexity, which tends to happen in complex cloud native setups.

Agreed, in general. But don't forget about the definition of micro :-) This is an optimization problem rather than a conceptual one.

I love Martin Fowler's one pager called Snowflake server - it aged very well and I still use it as a reference in the cloud era. And this text is also good advice IMO. What I feel that is missing on what he calls the "Microservice

Thanks for sharing the story. Despite the whole TCO being higher, I wonder how the 8K to 6K reduction happened. On AWS, fargate containers way are more expensive than VMs and non fargate containers are kind of pointless as you have to pay f

Thank you as well, for sharing these notes about your setup. Indeed concentrating everything in the same monitoring system is very helpful as it reduces the cognitive load. You can likely do the same with Icinga. Feel free to reach out on L

The longer you wait the harder the pain. The less you wait the more frequent the pain. So it depends on the function that converts intensity and frequency to suffering :p But, most importantly, the fact that LTS gives you a choice is what I

Like 12 years of life cycle is not enough for you to plan a transition? You can use the entire life cycle but not one is forcing you to. You can update from one LTS to another every 2 years, or 4 years, or 5 years... you decide.

Also "scalability" is multi dimensional. I've seen, in the same company, infinite scalability in one downstream system whereas the upstream system it depended on was manually feed by fragile human-driven processes because the

The questions are short but the answers would be long. Puppet manages all fine grained OS resources (files, dirs, repos, cronjobs, sudo declarations, firewall rules, etc) and you aggregate those resources into classes which are then pushed

I don't mind elaborating - the fact that people are asking me questions reminds me that I need to invest a bit more effort on some articles. This case is actually pretty simple. Puppet applies the configuration you declare impotently w

Once you do it for long enough it might be worth it to consider configuration management where you declare native structured resources (users, firewall rules, nginx reverse proxies, etc) rather than writing them in shell. I use Puppet for d

Well that's exactly the point! Creating complex cloud resources with, for instance, Terraform, is less reproducible than a shell script on an LTS system like Ubuntu or RHEL - that's because the cloud provider interfaces drifts and

My comment about pip is orthogonal to Docker. This is the same with or without Docker - I added a comment on this thread with more detail.

If you really want to open that can of worms, here it goes: Pipy is an informal source of software that has low security levels and was infested with malware many times over the years. It does not provide security updates: it provides updat

I mentioned Docker because it interests many developers but on VMs that I control I do not need Docker at all. Deploying with Docker provides host OS independence which is nice if you are distributing but unnecessary if the host is yours, r
