👋 Intro

Welcome to the December edition of CloudNative.Now - a monthly newsletter that covers all that has been happening in the cloud native world in the past month!

Can you believe it's been a whole year of this newsletter?! 🤯 The time has flown by. If you missed any months, you can always catch up from the archive.

I was originally expecting this issue to be mostly a look back on the past year, anticipating not much happening this month due to the holiday period and general end-of-year slowdown. But it seems that doesn't slow down the cloud native community! 🚀 There has been plenty going on this month from new Kubernetes releases to several open CFPs and a sprinkling of articles around some serious downtime recently.

I hope you've all had a wonderful holiday, whether you celebrate or not, and I wish each and every one of you a truly fantastic new year. 💙 Here's hoping 2026 bring you all everything you want! 🎆

As always, you’re invited to subscribe to the email newsletter or add the RSS feed to your favourite feed reader to make sure you don’t miss anything! And please help to spread the word and recommend this to your friends and network if you find the content useful! 💙
