DevOps na Praia Sep/2026 🤝 #11 Cloud Native Porto | CNP

Back from summer vacation? So are we! DevOps na Praia is excited to announce our September 2026 meetup.

DevOps na Praia September/2026 marks our rentrée, and we're doing it alongside good friends: DevOps na Praia 🤝 Cloud Native Porto #11
An evening of platform engineering, data pipelines and developer experience, with time to catch up with the community after the summer break. Made possible with the support of Cleva, who are hosting us, and with the help of synvert xgeeks as an ongoing CNP sponsor. Also a big thank you to Miro for sponsoring the Catering for the evening!

📍 Location: Cleva - Porto
📅 Date: September 24, 2026
⏰ Time: 18:30
Agenda & Talks:

🎤 19:00 - From Airflow 2 to Airflow 3: Migrating 100+ DAGs Without Downtime or Developer Burden
Speaker: Gonçalo Costa - Data and Site Reliability Engineer @ Miro
Abstract: Migrating a production Airflow deployment from version 2 to 3 without disrupting hundreds of DAGs across multiple teams sounds scary (and it is). In this talk I will share how we migrated versions without a big-bang cutover, without weeks of cross-team change requests, and without leaving our pipelines in a broken state.
I'll walk through how we built a compatibility layer to make sure our code runs on both versions during the migration, how we used AI-tooling to orchestrate 400+ DAG changes and how our on-demand ephemeral environments, full k8s deployments deployed for each pull request, helped us experiment and test all the required changes.
Most important of all, I will share what we learned, where we failed and what we would do better next time.

🎤 19:30 - Zero Docker, Zero Kubernetes: The Power of DevBox
Speaker: Carlos Nogueira - Senior Platform Engineer @ Flutter
Abstract: Are you tired of wasting time on environment setup, compatibility issues, or the dreaded 'but it works on my machine' problem? DevBox is the answer to modern development friction. In this session, we will explore what a DevBox truly is and how it allows teams to standardize their environment, ensure consistency from development through production, and achieve maximum velocity. If you want to cut down on setup time and ramp up coding time, this is for you.

🍕 20:00 - Networking, Food & Drinks
Join us at Cleva's offices in Porto to connect with the community, share ideas, and network with Cloud Native and DevOps enthusiasts!

A big thank you to Cleva for opening their doors and hosting this edition, and to synvert xgeeks and Miro for making this evening possible with the amazing caterign that we will have.
See you there! 👋
