I converted this site from Wordpress to Hugo with wp2hugo to get me started. Reason behind this is that I really liked writing the blog in Markdown when I wrote a post for AlmaLinux, besides that it also gives a great showcase for your abilities in working with Git and code on its own. One of my goals was to maintain my search engine rankings by keeping the old pages at the same location, which it handled nicely. ...
This year was a busy year with bigger long running projects, which take quite a toll but are in the end very rewarding. In a small list the following activities are the most notable: Migrated a Nagios Core monitored environment to a Zabbix environment, based on the Zabbix agent 2 and Active checks; Previously we built the Nagios config files with Python from our CMDB, in Zabbix we use Autoregistration rules based on metadata. Consolidated 3 datacenters, consisting of 10 racks into 2 datacenters with 8 racks, doing so decommisioning older servers and rebuilding the entire network infrastructure, transistioning from traditional copper to fully fiber, standardized on Singlemode, fully multihomed, built with Juniper Apstra; Upgraded two PowerDNS nameservers to up-to-date versions; Upgraded multiple Proxmox clusters from 6.x to 8.x; Upgraded multiple Ceph clusters from Nautilus to Reef; Deployed and implemented multiple MariaDB Galera clusters; Migrated servers from one Fortigate VDOM to another with minimal impact; Expanded Ceph clusters and replaced nodes with live workloads; Cleaned up two RIPE ORGS and handled the audit of one; Built a campus network based on Fortiswitches managed by Fortigates. Worked together with Juniper on a Case Study about Juniper Apstra; Handled multiple CentOS 6 to AlmaLinux upgrades; Upgraded Zabbix 6.4 to 7.0 LTS; Gave multiple presentations and trainings about networking and Proxmox; Attended AlmaLinux Day, CloudFest, Juniper NL Tech club, Dutch Proxmox day, NLNOG Day 2024 and Cephalocon which sparked my interest and got me more involved in opensource communities and trying to bring my relevant input;
It鈥檚 becoming a tradition now I guess :-), another small list of projects I worked on the past year. Consolidated some PowerDNS based nameservers into one, to make administration easier; Migrated a Software VDOM link to NPU VDOM link with minimal downtime; Started working with RIPE; Enabled IPv6 in two Service provider networks; Built a Service provider network based on Juniper, EVPN/VXLAN with the super cool tool called Juniper Apstra; Built a huge Juniper Virtual chassis for a customer; Built a classic out-of-band network; Decommissioned a lot of legacy networks; Replaced live routers running in a virtual chassis with a VRRP set-up without downtime; Consolidated some pfSense firewalls into a Fortigate; Written lots of ansible plays and improved older ones; Enabled IPv6 SSL-VPN and Nameservers; Implemented a couple of HA MariaDB Galera clusters; Designed and built 8 new datacenter racks from scratch, while also switching from copper to fiber, keeping the cables neat; Worked with some great external partners; Paved the way for a good foundation to build a high available Zabbix 6.4 cluster.
A small list of projects I worked on the past year, these are the most interesting ones. Migrated ancient nameservers based on PowerDNS with a sturdy base of the latest DNSDist and PowerDNS; Migrated a stack of VM鈥檚 and their relevant IP space from one provider to another, between Openstack and Proxmox; Guided the migration of a older Fortigate cluster to a new one with minimal downtime; Started working with OSPF; Built a good backup solution on top of Proxmox Backup Server; Created an automated and standardized deployment with Cloud-init, Ansible, Gitlab and AWX. Updated lots of Proxmox and Ceph clusters.
