Why I switched to systemd-resolved

April 15, 2020

Yesterday, a controversial proposal got posted in the Fedora Devel mailing list: enable systemd-resolved by default. I see this change favorably since I already enabled it a few weeks ago, and I find it a very sensible option. First, I have to admit that I see systemd and its mission of standardizing the core of the Linux user-space very favorably. At the current level of evolution of Linux, over time, this standardization and consistency will pay off much more than other alternatives.

VPN with NAT in Google Cloud

March 1, 2020

Google Cloud provides the capability of terminating a VPN connection with a VPN Gateway. The problem is that the VPN Gateway - at the moment - is relatively limited in capabilities. One of the missing capabilities I would have liked to see implemented is the NAT capability. VPNs can be used to connect the machines of two different parties. Although this is usually not the best architectural pattern, since a connection on the public internet encrypted at the Transport Layer is often a better option, it’s relatively common in more legacy environments.

FOSDEM 2020

February 2, 2020 - Bruxelles, BE

This year, as it has happened for the last few years, I’ve been at FOSDEM. As always, I’ve enjoyed it a lot, and that’s why I continue to go there, and every time I have to suggest other people which events to attend in Europe, I always mention FOSDEM as the main event. I think it’s fascinating to see how room sizes and crowdedness of the rooms changes over time. Years ago, the container-related rooms (containers, container security, Go) were relatively small, but already crowded, and over the years, the rooms got bigger and bigger.

DevConf 2020

January 27, 2020 - Brno, CZ

As it happened at other times in my life, I managed to be present at DevConf. DevConf is one of the best conferences that I attend. The reasons are many and varied, starting from the location that I find relatively stress-free. Another reason is the fact that there are many different kinds of sessions, and many sessions are not overcrowded, so it is relatively simple to participate in any session you would like to.

Resource scarcity in Public Clouds

December 10, 2019

In the last couple of weeks, I’ve seen problems allocating resources in the Google Cloud Platform in the Frankfurt region. The problem seemed to have occurred due to the high requests Google customers made to sustain their businesses during the Black Friday, Thanksgiving, Cyber Monday period. Making some searches on Google, I’ve found out that this is not the first time it occurs, and this is not only a GCP problem since AWS and Azure had similar incidents.

AWS Solution Architect - Associate

November 8, 2019

A couple of days ago, I did re-take the AWS Certified Solution Architect - Associate exam. This was my second time at this certification (I did it the first time in 2015), and I had to retake the exam since my certification expired in 2017. The exam was fairly different this time from the previous time. The first thing I noticed is that the certification itself is no longer expiring after 2 years since the validity got extended to 3 years.

AWS Cloud Practitioner Essentials

October 10, 2019

As part of my AWS re-certification path, I decided to start from the very begin, with the AWS Cloud Practitioner Essentials. I was sure to pass the exam, but since in the company I work for other people will be required to become AWS certified, I wanted to check out the exam beforehand, to be able to suggest to the people the right certification for them. The exam is fairly straight forward and is mainly focused on the advantages of AWS and cloud in general.

Google Cloud Snapshot Cleaner v0.2.0

September 22, 2019

Last week, in a previous article , I’ve introduced you to gcsc (Google Cloud Snapshot Cleaner). I’ve just released the version 0.2.0 of it, and it has a lot of clean-ups done, both in the code and the user experience. There are also some new features, but the one I’m more satisfied with, is the introduction of the http subcommand, to expose an HTTP server. The webserver will listen to any URI and Methods, and the request will trigger the snapshot clean-up.

Google Cloud Snapshot Cleaner v0.1.0

September 16, 2019

I’ve just tagged the first version (0.1.0) of gcsc (Google Cloud Snapshot Cleaner). The idea behind this small software is to create a more flexible way to keep the Google Cloud Disks Snapshots tidy. Google Cloud does provide a very nice way to automatically snapshot your disks , leveraging the resource policies. This is very nice, since it allows you to be sure that the Google Cloud always and reliably snapshots your disks.

Google Professional Cloud Architect

August 30, 2019

After less than a week from achieving the Google Associate Cloud Engineer certification, I took the Google Professional Cloud Architect exam. Preparing this exam, I found odd the fact that Google provides three case studies to bring to the exam. I was even more impressed by the number of questions around those cases. It felt odd since it felt like you could prepare very well those three case studies and be advantaged in the exam.
