Paul Baran (born Pesach Baran /ˈbærən/; April 29, 1926 – March 26, 2011) was a Polish-American engineer who was a pioneer in the development of computer networks. He was one of the two independent inventors of packet switching.

Architecture is hard sometimes--people keep offering up some new idea that quickly becomes the mainstream “way to do it” without any context or nuance, and the industry, desperate to find ways to improve their architecture, snaps it up without hesitation. Microservices was the latest in the trend, and it’s time we dissected the idea and got to the real root of what’s going on.

Monolith vs microservices ... small server vs big server...

We have all gotten so familiar with virtualization and abstractions between our software and the servers that run it. These days, “serverless” computing is all the rage, and even “bare metal” is a class of virtual machine. However, every piece of software runs on a server. Since we now live in a world of virtualization, most of these servers are a lot bigger and a lot cheaper than we actually think.

In short, the argument goes, the ability to write scheduling policies in BPF greatly lowers the difficulty of experimenting with new approaches to scheduling. Both our workloads and the systems they run on have become much more complex since the completely fair scheduler was introduced; experimentation is needed to develop scheduling algorithms that are suited to current systems. The BPF scheduling class allows that experimentation in a safe manner without even needing to reboot the test machine. BPF-written schedulers can also improve performance for niche workloads that may not be worth supporting in the mainline kernel and are much easier to deploy to a large fleet of systems.

There are hackers—believe it or not—who just love the art of building software. They do it for the challenge, for the fun of it. They aren’t trying to make a million dollars.

This is an attempt to stop a war. I hope it is not too late and that somehow, magically perhaps, peace will prevail again.

The latecomers into the arena believe that the issue is: “What is the proper byte order in messages?”.

There is something special in simple code. Here I’m not referring to simplicity to fight complexity or over engineering, but to simplicity per se, auto referential, without goals if not beauty, understandability and elegance.

Real, productive workers are relentlessly squeezed and exploited. The remainder are divided between a terrorised stratum of the, universally reviled, unemployed and a larger stratum who are basically paid to do nothing, in positions designed to make them identify with the perspectives and sensibilities of the ruling class (managers, administrators, etc.)—and particularly its financial avatars—but, at the same time, foster a simmering resentment against anyone whose work has clear and undeniable social value.
