I’ve been away from web application development for quite a few years. To be honest, it has been a pleasant experience: no “annoying” customer requests, no endless changes and rewrites, only important stuff (TM). Just kidding of course, but systems programming is indeed different. One of the defining features

Club Sandwich Starting usage pattern is a “sandwich” like structure, where our application is between the two HAProxy layers. All incoming traffic is going through HAProxy, which provides protection, SSL termination, and logging, while my app is not exposed to the outside world (it usually listens only on localhost/loopback)

TLS Calzone For some services, securing and logging access is paramount. For HTTPS traffic you can often get by with Basic HTTP Auth. Managing such solution can become slightly complicated (e.g. you need to implement account and secret management), so you try to find next best thing. Aside from

Docker Cake This one is very easy on the eyes (and stomach), and rather useful. You can have your cake and eat it too! Just launch HAProxy inside docker container, where HAProxy will proxy the trafic and log to stdout. In addition to that, HAProxy can start and monitor additional

Service Discovery Ice cream We want to show you how to use HAProxy and Hashicorp Consul for fun and profit. You can even sprinkle a lightweight orchestrator on top of it, for better taste (for this we will use Nomad, a lightweight alternative to Kubernetes). The starting point are two

Belgian OLAP Cube Clickhouse is a very interesting open source columnar database, mostly used for online analytical processing (OLAP). It speaks custom native TCP protocol, but also supports HTTP, so you don’t really need any special client or “driver” to talk to it. There are many great features, too
