New applications and workloads are constantly being added to Kubernetes clusters. Those same apps need to securely communicate with resources outside the cluster behind a firewall or other control point. Firewalls require a consistent IP, but routable IPs are a limited resource that can be quickly depleted if applied to every service.

In his HAProxyConf 2019 presentation, William Lallemand (Senior HAProxy Developer) shows how process management in HAProxy has evolved since the beginning of the project; With the advent of systemd, new techniques had to be developed so that users could reload HAProxy safely. The Master-Worker mode simplifies the management of HAProxy processes and introduces interesting features.

Ever since the work from home (WFH) and study from home (SFH) initiatives became widespread due to the outbreak of COVID-19, there has been a huge effort among organizations to either set up new broadband connections or upgrade existing connections with higher bandwidth speeds. No matter the number of command centers an internet service provider (ISP) might have, keeping up with users’ demands—whether it’s about network speed or volume—can be a colossal undertaking.
