Congrats! Itโs still on my to watch list!
Pretty cool how AWS monitors and protects against threats like this.

This looks really interesting!
Amazon released 40 new features during Matt Garmanโs opening keynote! Go check out buff.ly/xNZK1L9 to see all of them, including related blog posts ๐

๐ ๐ The AWS Lambda roadmap is now open and on GitHub! See what we're working on, researching, and planning. Provide feedback, collaborate on ideas!

Interesting! I wasnโt aware such a library/framework existed.
AWS has also removed a log4j patch from the Java 25 runtime to restore optimal performance. This was implemented when Log4shell hit the industry and was in all previous runtimes.
Starting with Java 25, Lambda no longer stops tiered compilation at C1 for SnapStart and Provisioned Concurrency.
If you deploy Java 25 functions using container images, you can either implement your own AOT caches or continue using CDS.
Lambdaโs benchmarking results show that AOT caches deliver faster cold start performance compared to CDS. ๐ AOT caches are now enabled by default in the Java 25 runtime to provide performance benefits.
AWS Lambda replaces the traditional Class Data Sharing (CDS) with ahead-of-time (AOT) caches. This is an advanced optimization feature from Project Leyden that is designed to improve application startup times and reduce memory footprint.
There is a lot to unpack from this release though. Itโs not just a runtime update.
This is great! Amazing to see it gets released so close to the Java 25 release! aws.amazon.com/blogs/comput... #java #aws #lambda
In July, AWS announced a powerful update to Amazon ECS with built-in support for blue/green deployments. Now two additional built in deployment strategies have been added: linear and canary deployment. This eliminates having to use CodeDeploy. aws.amazon.com/about-aws/wh...
Thanks! ๐
Likewise!

It seems some services in us-east-1 still have degraded operations. Thatโs a long disruption ๐ฒ. I hope they will share an extensive post mortem. Looking forward to learn from the lessons learned!
Ah yes I misunderstood. I expect the same that people are misreporting.
Not sure what that graph is based on though. I don't see any issues when looking at the Azure status page. It might be lagging behind off course. azure.status.microsoft/en-gb/status
While trying to figure out of there was anything wrong with our jira and bitbucket cloud signin it seems AWS is having issues in us-east-1 .

Yeah I had the same feeling and figured the same ๐
Yes that was a late one! I think it was around 6 or 7pm or so Vegas time
Yeah I know. Last time I was in Vegas though. Time wise it would have been much better if it was around 15:30 Vegas time like this year. Especially with all the long days and jet lag ๐
