📑 Quarkus : the fast, eco & DevEx-friendly framework

❔ About

I recently saw the following content popup:

We have adopted this technology in our Team at opt-nc and feel everyday a large amount of benefits on the DevEx and more generally on our whole DEVOPS pipeline.

After watching this content, I felt that sharing it internally may help improve our on-boarding process, so I decided to prepare a ready-to-use playlist on top of it.

🎯 What to expect

This post is dedicated to help people better understand where does Quarkus comes from and why it helps a lot... and why we love using it on our daily missions.

Each bookmark targets a specific aspect of this webinar so you can efficiently come and pick the point you must learn a bout within the next few minutes you have.

🪝 Focus points

Essentially, this playlist will cover the following aspects:

• 📜 Where does Quarkus come from: then & now
• 💳 Cloud concern and impact
• 📊 Application density (how much can be achieved with a given amount of resources)
• ℹ️ The cost of dynamism
• 🦥 DevEx : Testcontainers & devservices
• ⚖️ BUILD time vs. runtime considerations
• 🌿🌍 Green IT & carbon considerations

⚡ The MUST WATCH

Also, if you are very (very) short in time from my point of view, there are two MUST watch:

• 🔑 The cost of dynamism and core Quarkus concept
• ⚙️ Quarkus and the "closed world assummption: how does a framework start

📑 Playlist

1. Intro
2. Back in 2015
3. 2022 : Fast & light runtimes
4. 2011-2013 : Java shift to microservices, containers & cloud
5. Container platform and is Java designed for the cloud: GO vs. javascript/node.js vs. Java
6. Running application in the cloud concerns (start/stop often) bring apps up and down very often
7. Applcation/service density and Quarkus
8. KPIs Quarkus REST app startup time (Quarkus+graalVM, Quarkus +OPenJDK, )
9. How does startup time matter (even without doing serverless) and auto-sclaing considerations
10. Memory footprint and density considerations
11. About throughput (native vs. JVM)
12. MUST WATCH : the cost of dynamism and core Quarkus concept, immutable apps
13. MUST WATCH : Quarkus and the "closed world assummption (and dev ex impact)" : BUILD time vs. runtime : pointless dynamic runtimes (about class loading, ) : how does a framework start
14. (From scratch) Live code session (DevUI, database persistence w/ Panache, psql devcontainers, testcontainers, podman, service auto )
15. testcontainers auto-provisioning and dev services (databases, redis, keycloak, kafka, elasticsearch, kubernetes, custom ones...) focus, configuration
16. is Qharkus greener (KPIs, experiments, ) : Spoiler : native consumes more carbon than JVM
