SONiC build performance – thoughts and next steps
by Rankan Sen March 30, 2026

March 30, 2026

Dear all, Over the past few days, we’ve been running multiple SONiC builds as part of the SCOMB effort, and I spent some time stress testing the build process. A few quick observations: * The best speedup so far was with *16 parallel jobs* * Build time was approximately *3 hours* * A completely fresh build (no cached/pre-sourced images) takes around *~5 hours* Even with these optimizations, a build time of ~3 hours is not practical for day-to-day development, particularly when multiple users are iterating on builds. To support a more collaborative and efficient workflow, this needs to be reduced further. From what I’ve seen so far: * There are likely *redundant packages and images* in the build * Not everything included seems necessary for a *basic or iterative build* So a first step could be: * Reviewing dependencies more critically * Stripping down the build to only what’s actually required That said, this is just an initial direction. There are likely better approaches (e.g., caching strategies, registry mirroring, incremental builds), so it would be great to get more input. If you have suggestions, please share them here: https://gitlab.com/alasca.cloud/scomb/sonic-buildimage/-/work_items/18<https://gitlab.com/alasca.cloud/scomb/sonic-buildimage/-/work_items/18> Also, feel free to pick up any open tickets if something looks interesting.

by Helena Ott March 30, 2026

March 30, 2026

Hey everyone, I am very excited to announce our *second ALASCA community Hackathon*. We are inviting you all to join us on *July 1st and 2nd in Stuttgart at Urban Spaces* (https://urbanspaces.de/de) to get together again and spend 2 days working on and further advancing the assisting projects as well as related topics within ALASCA!

ALASCA SCOMB GitLab
by Helena Ott March 5, 2026

March 5, 2026

Hi Guys, attached to this mail you'll find the meeting notes for our last call. As a reminder: we have established action items to work on, which I have now integrated into the ALASCA SCOMB Gitlab. Most of the issues don't have people assigned to them yet, since not everyone has joint the repository and not all task where taken by someone in our last call. If you'd like to be included and want to start working on SCOMB with us, please request access to join this repository <https://gitlab.com/alasca.cloud/scomb>. You can also join our Matrix channel <https://matrix.to/#/!RbUuBLWOKNKYPHtFDF:matrix.org?via=matrix.org&via=matri…> for the project. Ideally, these issues will be our basis for progress tracking in our montly calls. As of now, the issues I've created are not up to my preferred standard yet and are missing some clear instructions and/or expectations, which is due to the fact, that I don't fully understand the material. Please bear with me, as I learn. ☺️ Feel free to join the repository, grab tasks and let's get started! Please also feel free to add your own issues if you think of any or specify the ones I have added with more detailed information. Thanks for your support!

Hello Rankan, thanks for your quick reply. Currently we won't build SONiC because installation date is too close now (next week), however please let us know once community build with MLAG support is available - we will give it a try with our next cluster installed.

ALASCA - SONiC Community Build
by Helena Ott Feb. 23, 2026

Feb. 23, 2026

Hi everybody, welcome to the ALASCA SONiC community mailinglist. We are excited to pick things back up after the christmas break and really get started. As a next step, I'm sending everyone the meeting notes from our first meeting back in December. We did orginially plan having a SCOMB meeting every two weeks, however due to full calendars, we've decided to get started with a monthly meeting. How does the third Thursday of every month sound? So that would be Thursday, February 19th - March 19th - April 16th and so on. In this *dudle* <https://dud-poll.inf.tu-dresden.de/alasca-scomb/>, let's vote on the time. We can do 11 am, 2 pm or 3 pm. I'd appreciate it, if you'd let me know in the voting what time would work best for you, so that I can send out the invitation for the upcoming months. Thanks so much! We are excited to get started!

Deutschland-Stack und Digital Network Act
by Daniel Gerber Feb. 19, 2026

Feb. 19, 2026

Liebe SONiC-Community, Ich möchte euch gern über zwei Dinge informieren, die mir kürzlich über den Weg gelaufen sind: 1. Deutschland-Stack: Die zweite Konsultationsrunde des BMDS wurde abgeschlossen. Dabei hat unter anderm das Sovereign Cloud Stack <https://sovereigncloudstack.org/> (SCS) Projekt erneut eine Einwendung abgegeben, die ich euch an diese Mail mit angehängt habe. In der Stellungnahme heißt es: Im Bereich von Software-Defined Networking bietet sich ggf. ein Blick in Richtung SONiC an. Im Rahmen des SCS Förderprojektes wurde hier bereits tiefergehend geschaut und auch in der ALASCA-Community wird gerade aktiv an SONiC Community Builds gearbeitet. 2. Digital Networks Act: Die Initiative der EU-Kommission zielt darauf ab, den Zugang zu sicheren, schnellen und zuverlässigen Verbindungen für den Übergang zu einer cloudbasierten Infrastruktur und künstlicher Intelligenz zu verbessern. Ich bin über die Stellungnahme der FSFE <https://fsfe.org/news/2026/news-20260218-01.en.html> darauf aufmerksam geworden und könnte mir gut (als Laie) vorstellen, dass die Ziele des Community Builds sehr gut mit denen der FSFE und der grundsätzlichen Zielrichtung übereinstimmen. Es wäre daher sinnvoll ein kurzes Feedback bis zum 16. April 2026 über das EU-Portal abzugeben <https://ec.europa.eu/info/law/better-regulation/have-your-say/initiatives/1…> und damit dann auch Werbung zu machen.

SONiC Schwerpunkt bei BDBOS
by Daniel Gerber Feb. 4, 2026

Feb. 4, 2026

Liebe SONiC Enthusiast:innen, Ich habe eben diese Link <https://www.linkedin.com/posts/bdbos_bdbos-modernisierung-netzinfrastruktur…> auf LinkedIn gesehen und wollte es gern mit euch teilen. BDBOS tritt Linux Foundation bei und treibt Vorhaben im Open-Source-Bereich voran Die #BDBOS <https://www.linkedin.com/search/results/all/?keywords=%23bdbos&origin=HASH_…> arbeitet fortwährend an der #Modernisierung <https://www.linkedin.com/search/results/all/?keywords=%23modernisierung&ori…> ihrer #Netzinfrastrukturen <https://www.linkedin.com/search/results/all/?keywords=%23netzinfrastrukture…>, die einen der Grundpfeiler der digitalen Kommunikationsarchitektur in der öffentlichen Verwaltung bilden. Dabei spielt der Einsatz von Open-Source-Software eine wichtige Rolle, um die digitale Souveränität zu stärken. Zur weiteren Förderung des Open-Source-Ansatzes ist die BDBOS der Linux Foundation beigetreten. Der Beitritt und das Engagement der BDBOS schaffen Möglichkeiten, gemeinsam mit der Linux-Community an neuen Standards und Lösungen zu arbeiten. Diese sollen perspektivisch auch den Weg in die öffentlichen IT-Netze finden. Aktuell liegt einer der Schwerpunkte auf der Netzwerk-Software #SONiC <https://www.linkedin.com/search/results/all/?keywords=%23sonic&origin=HASH_…> als Betriebssystem für Router und Switche. In Verbindung mit der Programmiersprache #P4 <https://www.linkedin.com/search/results/all/?keywords=%23p4&origin=HASH_TAG…> sind Einsatzszenarien auf entsprechenden Geräten vorstellbar. Dies bietet nicht nur die Chance, den sogenannten Vendor Lock-in zu reduzieren. Durch Code-Reviews und -Analysen werden so auch mehr Transparenz und Sicherheit geschaffen. Die BDBOS wird ihre Erfahrungen als Netzbetreiberin des Bundes mit einbringen und freut sich auf die Zusammenarbeit mit The Linux Foundation <https://www.linkedin.com/company/the-linux-foundation/> und der SONiC Foundation <https://www.linkedin.com/company/sonic-fund/> sowie all ihren Mitgliedern. —— Dr. Daniel Gerber Softwaredeveloper ALASCA - Verband für betriebsfähige, offene Cloud-Infrastrukturen e.V. c/o Cloud&Heat Technologies GmbH Königsbrücker Straße 96 | 01099 Dresden +49 351 479 367 00 daniel.gerber(a)alasca.cloud | https://alasca.cloud/ Let's learn.
