Enough with “firewalls”
A mythical conversation on firewalls, and some observations
“Let’s put the firewall here, so it can protect the servers in this part of the network.”
“How would you define a firewall?”
“You know, the appliance that, well, protects servers and other machines from outside threats…”
“And how does it do this?”
“By filtering the traffic using some sort of stateful mechanism, and network address translation, and deep packet inspection, and blocking certain ports, and…”
“In other words, it’s a bunch of services on a single device?”
“Yes…”
“Then maybe we should think in terms of services instead of appliances.”
I’ve never actually had this conversation, but I’ve had many similar ones across my times as a network engineer. I’ll admit, in fact, that it took a lot of conversations like this (with me on the receiving end) to grock the difference between a service and an appliance, and to see that my constant thinking in terms of appliances (or even devices) was actually hindering my ability to design networks. Let me give you two specific reasons you should think of security services, instead of security appliances.
First, When you disaggregate the “things a firewall Continue reading

Docker + Golang =
This is a short collection of tips and tricks showing how Docker can be useful when working with Go code. For instance, I’ll show you how to compile Go code with different versions of the Go toolchain, how to cross-compile to a different platform (and test the result!), or how to produce really small container images.
The following article assumes that you have Docker installed on your system. It doesn’t have to be a recent version (we’re not going to use any fancy feature here).
Go without go
… And by that, we mean “Go without installing go”.
If you write Go code, or if you have even the slightest interest into the Go language, you certainly have the Go compiler and toolchain installed, so you might be wondering “what’s the point?”; but there are a few scenarios where you want to compile Go without installing Go.
- You still have this old Go 1.2 on your machine (that you can’t or won’t upgrade), and you have to work on this codebase that requires a newer version of the toolchain.
- You want to play with cross compilation features of Go 1.5 (for instance, to make sure Continue reading
