@kevindubois.com it would be great to discuss about the architecture in Antwerp and see where we can make it better!! 😁

Plus, the heavy load lasts ~30s or less, so IMO adding pod autoscaling into the mix could do more harm than good, as the database would become the bottleneck...

Behind the Scenes of Devoxx Ticket Sales How we managed the high load of registrations for Devoxx Belgium

Since the work is mostly done by the database (see ticketguy.dev/blogs/2023-0..., old but still relevant), we usually need 4-5 pods distributed among the k8s cluster nodes, as Alf.io works reasonably well with moderate resources (1/2)

Patrick S. on LinkedIn: #hackcommitpush #jreleaser #workhorz The first #HackCommitPush event in Switzerland took place in the beautiful HSL in Rotkreuz. The main organisers from Java User Group invited and mostly Java…

Feedback from one of our project leads at #Hack.Commit.Push

We’d like to run HCP at HSLU Rotkreuz again next year, perhaps with two additional locations across Switzerland.

Of course HCP Paris will be back again. Stay tuned!

Open Source FTW!
