Catching up on the latest AWS news blogs around September 2026 – Study session materials for AWS trend check
This page has been translated by machine translation. View original
Hello, I'm Usuda.
Everyone, are you keeping up with the latest AWS news? (greeting
I've turned the materials from the AWS Trend Check Study Group held internally into a blog post.
The AWS Trend Check Study Group is an internal study group held under the theme of "Let's catch up on the latest AWS news and updates through blog posts, and all become trendy together."
On this blog site, DevelopersIO, all kinds of blog posts are published daily, and among them I pick up what I personally find interesting, centered on AWS updates (plus some self-promotion of my own blog), and introduce them briefly roughly once a month.
In September, we had 106 picks. New features and services keep coming out one after another, so it seems the momentum won't stop until re:Invent.
By the way, if you just want to catch up on the latest AWS news, 週刊AWS is recommended, and for generative AI, 週刊生成AI with AWS is great, but reading DevelopersIO blogs offers different insights, explanations, and fun compared to the official AWS content, so I'm taking the approach of catching up through blogs. There's also plenty of interesting non-AWS content!
Now let's go!
