Recently I wanted to try changing the API we have at CardGames.io and try using the Serverless framework. Serverless has been a hot topic in the tech world for the last few years and I was procrastinating wanted to keep my tech skills up to date by trying something new, so I decided to spend a few hours learning about…
It feels like we’re starting to pass the peak of the hype cycle of microservices. It’s no longer multiple times a week we now see a blog post of “How I migrated my monolith to 150 services”. Now I often hear a bit more of the counter: “I don’t hate my monolith, I just care that things stay performant”. We’ve actually…
Disclaimer: I’m not a network engineer and never have been - a tame network engineer has been consulted to ensure factual and terminological accuracy. The following is an in-exhaustive run down of everything I’ve learnt from building and using network infrastructure on Amazon Web Services. If you find you have no…
I started to compile a list of public failure/horror stories related to Kubernetes. It should make it easier for people tasked with operations to find outage reports to learn from. Since we started w
I realized I haven't posted about my DrupalCon Seattle 2019 session titled Everything I know about Kubernetes I learned from a cluster of Raspberry Pis, so I thought I'd remedy that. First, here's a video of the recorded session: The original Pi Dramble 6-node cluster, running the LAMP stack.
Most Dockerfile examples for Python you’ll find on the Web are broken. And that’s a problem.
TL;DR: - Mail is not hard: people keep repeating that because they read it, not because they tried it - Big Mailer Corps are quite happy with that myth, it keeps their userbase growing - Big Mailer Corps control a large percentage of the e-mail address space which is good for none of us - It's ok that people have…
Two days at PDX DevOpsDays, a gathering of system administrators who use version control, and write a lot of YAML.
The new pi has been released and it has a USB Type-C connector for power however people are finding some chargers are not working with it (notably macbook chargers). Some have speculated that this is due to a manufacturer limitation on the power supplies however it is actually due to the incorrect detection circuitry…
The title for this blog post is a direct reference to Latency Numbers Every Programmer Should Know. There are several versions of those numbers available now...
I like to sleep, but more importantly, I like to sleep while my cloud service is running.
In one of my last experiments I replaced my crappy T-Mobile (now Magenta) 4G modem/access point with an OpenWRT-based cheap travel router and a 4G USB LTE modem. That doubled my speed over the wireless (WLAN) network but the setup was limited by the outdated and under-powered travel rooter. So I got myself a cheap…

For the past few years, I've been building and operating a large distributed system: the payments system at Uber [https://eng.uber.com/payments-platform/]. I've learned a lot about distributed architecture concepts…
My story of replacing three servers, across two countries, running two operating systems with a single server running Alpine Linux and Docker.
How the biggest cloud companies deliver the worst value
Load Balancers plays a key role in Web Architecture. In this post we are going to develop a simple load balancer with power of Go
In my position I probably shouldn’t have a favorite AWS product, just like you shouldn’t have a favorite child. I do have a fave service but fortunately I’m not an (even partial) parent; so let’s hope that’s OK. I’m talking about Amazon Simple Queue Service , which nobody ever calls by its full name.
Here we are at the beginning of 2019 and I’m engaged in yet another discussion on the merits (or lack thereof) of keeping all of an…
Why startups can build valuable businesses by unbundling AWS: focused developer tools, better user experiences, and software that does one thing well.
DNS latency is a key component to having a good online experience. And in order to minimize DNS latency, carefully picking DNS servers and anonymization...
