My talk about #PegaProx for #Proxmox VE based clusters at the @FrOSCon conference has been accepted!

I'm happy to share some more insights about the project, development stages, integration of the ProxTools collection (like #ProxLB, #ProxPatch, #ProxSnap,...) and more! We'll end up in a live demo of PegaProx, orchestrating several Proxmox clusters, XCP-ng based ones and maybe I'll have already finished another great thing until that date 🙂

At the upcoming @FrOSCon conference, I'm talking about #PegaProx as a multi-cluster manager for #Proxmox VE and #XCPng based systems.

During this talk I share some information about how and why this project got crafted as well as some information about the projects' history.

Afterwards, I move over to a live demonstration where we will have a look at some great features that make the life easier for operators.
