Exploring eBPF – Part 3: Getting Started with Hubble

Welcome to the third post in my eBPF series: in my first post, I introduced eBPF and walked through how to use a sample code, in the second post, I talked about Cilium, an eBPF-based networking plugin for Kubernetes. In this third post, we’re going to jump straight from the previous post and leverage Cilium’s […]

Exploring eBPF – Part 2: Getting Started with Cilium

This is the second post in my eBPF series: in my first post, I shared my experience with applying my first basic eBPF code through the use of a tool called Bumblebee. In this part 2, I’m going to check out what is probably the most popular eBPF programs: Cilium. In part 3, we’ll look […]

Exploring eBPF – Part 1

I’ve been keeping an eye on eBPF for a little while. In fact, the first time I properly paid attention was when listening to one of my favourite Cloud podcasts: eBPF also caught my eye because the leading eBPF company out there (Isovalent) was cofounded by leaders in the cloud networking space and because they […]

Terraform and Splunk Part 3: Using the Terraform Provider for Splunk

This is the third post in my Terraform and Splunk series. After deploying Splunk with Terraform in Part 1 and setting up the Terraform Cloud integration in Splunk in Part 2, we are going to end this series for now by using Terraform to configure Splunk to monitor Terraform Cloud. For this, we are going […]

Terraform and Splunk Part 2: Setting up Splunk Dashboards and Searches with Terraform

This is Part 2 in a Terraform & Splunk Series. In Part 1, we deployed Splunk Enterprise using Terraform. The first part of my tests were actually based on Splunk Cloud as you can see from some of the screenshots below. Once I needed to use the Splunk APIs to configure Splunk with Terraform, I […]

Terraform and Splunk Part 1: Building a Splunk instance in AWS

As I work with global financial customers in my day job at HashiCorp, auditing and logging are topics that come up regularly. The vast majority of my customers would use Splunk as a log engine (Gartner-ly known as SIEM (Security Information and Event Management)) for a variety of use cases and HashiCorp partnered with Splunk […]

Policy-As-Code for Networking-As-Code

As much as I promote Terraform and other tools to automate and deploy infrastructure, I also begin to appreciate that the easier we make it for folks to deploy resources, the quicker it gets out of control. If you give a developer or an infrastructure operator the keys to the AWS account, then you might […]

Network engineers: will you ever dare to change?

A few years ago, I was trying to understand why a certain profession was so reluctant to change. I read some academic papers on metathesiophobia (fear of change) to try to understand better how to address it. I wanted to understand what made people in this particular line of work so afraid to change any […]

Consume the HashiCorp Cloud Platform APIs with Go

In my previous post, I had a first look at HashiCorp Cloud Platform (HCP) Packer. At the end of the post, I suggested that the value of HCP Packer will be multiplied when integrated in an API-driven architecture. The examples I used were: vulnerability is detected on an image → API-driven process to check which […]

First look into… HCP Packer

Last week, HashiCorp announced the public beta for HCP Packer, a managed service for Packer. Packer might not be as well-known as some of the other HashiCorp tools but it’s universally used to build golden images and templates and it quietly powers a lot of what happens in the public cloud: on Azure…. ….but also […]
