Scaling Kubernetes to Zero and Back
Think about a typical serverless functionality without actually implementing a serverless solution like Knative. Daniele’s tutorial on how to use Keda HTTP Scaler in Kubernetes to scale down pods when there is no HTTP traffic is quite a useful solution to save costs, particularly in non-production services or low-traffic services.

Is WebAssembly (WASM) the Next Big Thing?
Some of the Industry veterans who have seen the initial days of containers are comparing WASM with innovations like Docker and it is as important as containers. Also, in the recent episode of the Kubernetes podcast by Google, there are interviews with some of the KubCon attendees who think WASM is the next big thing. Some of the software such as CAD, modelling, image/video editing, gaming etc will be early adopters to get better performance and security by bringing complex computing into the browser.
If you are new to web assembly, I recommend this talk by Guy Royse to understand the evaluation from assembly languages to running a virtual machine sandbox in the browser and servers.
There is a survey published by CNCF about the current usage of WASM → https://www.cncf.io/blog/2022/10/24/cncf-wasm-microsurvey-a-transformative-technology-yes-but-time-to-get-serious/
