Quarkus: Runtime and Framework for Cloud-Native Java - Blog post #2 #2441

MichalMaler · 2025-10-22T12:45:13Z

A second blog post, the purpose of which is to showcase Quarkus' strengths from the two points of view:
One as a runtime, the second as a framework.

LGTM otherwise.

Not authoritative, but it looks good to me

I haven't read the post to be honest but I disagree with trying to tie us to some Google grand principles.
It's definitely not what was behind the inception of Quarkus.

@jherrman, May I request your language expert review? :)

@gsmet
I changed it to a neutral tone. Now I am not quoting Google or anything. Just pointing to an article I am using as a reference.

jherrman

A nice write-up overall, but some parts would benefit from a slight rewrite, IMHO.

@cescoffier Hello Clemenet!
May I request your review and hear your two cents on this? :)
Kind regards,

cescoffier

Great content. Need a bit more work to make it easier to read.

+For a broader industry perspective, see the link:https://cacm.acm.org/practice/application-frameworks/[ACM article on application frameworks].
+
+Quarkus shifts work from runtime to build time, thus enabling faster cold starts.
+Additionally, it offers the option to generate native executables with GraalVM's native-image, enabling cold starts in milliseconds and a minimal memory footprint, resulting in higher pod density, quicker horizontal scaling, and lower idle costs.

+Current native images typically use a single-threaded garbage collector, which is inefficient for large heaps and does not benefit from multiple cores.
+We generally recommend native execution for services that run on smaller instances up to two vCPUs with roughly two to four gigabytes of RAM, where startup time and memory footprint dominate cost and user experience.

+At the same time, your framework layer standardizes infrastructure, security, and operational integrations across services.
