Ask HN: Expert Level Cloud Learning Materials

In the last two years, I started listening to podcasts more and more, and there is a polar star for the Startup and growth section:

- https://www.lennyspodcast.com/ - Thanks, Lenny, for your work. I'm getting addicted to your weekly episode.

There are many exciting podcasts and blogs for the Cloud-side, but the level is heterogeneous. - https://cloudsecuritypodcast.tv - Cloud security vertical podcast episodes are long, but most are interesting. I found it more inspirational than knowledgeable, but it is a good resource.

- https://blog.awsfundamentals.com/ - Tobias and Sandro are doing a fantastic job with infographics to explain more readily the Fundamentals of AWS

What are your advice to have a good content?
