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,
M.

cescoffier

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

A couple more suggestions in terms of stylistics and grammar.

@MichalMaler Thanks for simplifying the security section, much easier to read. We can expand it but given that this PR covers a very wide ground, IMHO the current security related overview is good to go

cescoffier

I did a quick read , there are still a few issues.

It would be great to have someone doing a full read to find the transition issues.

I think it's good now. Anybody have any more comments?

I think it's good now. Anybody have any more comments?

Hello Jan @jmartisk . THX for the read. I will go with @galderz on the native/JVM part on Tuesday. Then I think it's ready.

MichalMaler · 2025-11-11T16:44:22Z

The next revamp will focus on the Security section, which I will work on with @sberyozkin tomorrow.
We are good to go then.

sberyozkin

Thanks @MichalMaler, as briefly discussed offline, your post covers a lot of ground, so a brief into to Quarkus security is sufficient and we can publish more focused posts later.

Thanks for working so hard on this blog post

galderz

"Performance that matters" section looks good, thanks @MichalMaler!

Hey @MichalMaler thanks for the article. I've added some comment and request Changes.

+But beyond speed and live reload, Quarkus integrates established Java specifications such as CDI-Lite, JAX-RS, and JPA, with implementations provided by Arc (CDI-Lite), RESTEasy (JAX-RS), and Hibernate ORM (JPA).
+It also enforces its own conventions, drives behavior with annotations, and defines how applications are structured.
+
+In this sense, Quarkus is a framework that also serves as a runtime and platform for cloud-native Java applications.


Through the text there is some inconsistency in how Quarkus is classified. Sometimes is a runtime, others a framework and others a platform.
The text would benefit if the these 3 identities were better clarified.

+
+These extensions integrate with Quarkus and participate in its buildtime and runtime lifecycle, making them first-class citizens of the Quarkus platform.
+
+=== Simplified developer experience


Dev services and continuous testing could have been highlighted.

_posts/2025-11-14-mmaler-blogpost-2-quarkus-runtime-and-framework-for-cloud-native-java.adoc

+Quarkus addresses these needs by shifting work from run time to build time, keeping one development model across JVM and native, and exposing production signals such as health checks, metrics, and tracing.
+
+Start with **JVM mode** for most services.
+It starts slower and uses more memory than native to start with, but just-in-time compilation raises steady-state throughput, scales well across cores, and offers mature garbage collectors and tuning options.


JVM is the first class citizen here (+90% usage) and we should highlight its strengths... That is starts FASTER and uses LESS memory than existing "traditional" JVM based runtimes.
I would leave limitations for the native mode section.

+Quarkus exposes:
+
+* Unified logging with link:https://quarkus.io/guides/logging[`quarkus-logging`].
+* Structured metrics and tracing with link:https://quarkus.io/guides/telemetry-micrometer-to-opentelemetry[Micrometer and OpenTelemetry].


I would remove structured from the sentence.

You could add centralized logging with OpenTelemetry

_posts/2025-11-14-mmaler-blogpost-2-quarkus-runtime-and-framework-for-cloud-native-java.adoc

+
+* A minimal core for fast startup.
+* Pluggable extensions for authentication, tracing, messaging, and more.
+* Dev Services for automatic provisioning of databases, brokers, and containers in dev mode.


Production ready would be the last place I would mention dev services. See above.
Things like health-checks and fault tolerance would make more sense here.

+
+Frameworks can serve as a foundation for creating higher-level abstractions.
+
+Quarkus fits naturally into this model — not by becoming a platform in itself, but by enabling teams to build their customized stacks and frameworks on top of it.


What is a platform?
