Hi @Yosu_Cadilla,
I don’t know about Kafka, but I do know redis is very fast with a small footprint. We have been using it reliable for 2yrs to track our container activity.
Also, I manage 16 LXD servers that run multiple web sites as you noted above to @turtle0x1 using Debian containers with NGinx and PHP 7.2. All totaled, I think we are over 770 websites spread across the LXD servers. For this application workload, LXD works great! Let me know if you want to discuss particulars of how we setup our websites and LXD servers.
