    From Legacy to Open: How IP Nexia Built a Production-Ready SONiC Network | Case Study [Part 1]

    Belgian service provider IP Nexia operates critical VoIP, unified communications, and connectivity services around the clock. With customers depending on uninterrupted availability, downtime is simply not an option. When its aging network infrastructure began reaching its limits, IP Nexia took a path few mid-sized ISPs would consider: replacing the legacy stack and rebuilding its network around an open networking architecture. In this episode, Michel Coric, CEO of IP Nexia; Alexander Deca, Chief Network Architect at Deca Consulting; Edgard Saad of Edgecore Networks; and Łukasz Łukowski of STORDIS explain how the team delivered a scalable, automated, and future-ready infrastructure—without disrupting live services during the migration. They discuss the business and technical pressures behind the transformation, the role of SONiC, and how Edgecore Networks and STORDIS provided an alternative to the traditional single-vendor model. In this episode, you’ll learn: → Why scalability became a critical business requirement→ How IP Nexia migrated its production network with zero downtime→ What open networking looks like for a mid-sized ISP→ How Edgecore Networks and STORDIS replaced the traditional vendor model→ The role of SONiC in the new architecture→ How automation improved network operations→ What changed after go-live in terms of reliability and business capacity→ How the new platform can support future AI and security workloads This is not a hyperscaler experiment or a theoretical proof of concept. It is a practical, repeatable open networking model that is already running in production. Subscribe for more real-world open networking use cases, SONiC deep dives, and infrastructure transformation stories from the field.

    Infrastructure as Prompt: AI Agents, Digital Twins & the Future of Network Automation with Kamal Bhatt

    What happens when infrastructure is no longer written only as code, but described as a prompt? In this CLOUDFEST Masterclass, Kamal Bhatt from STORDIS explains the concept of Infrastructure as Prompt — an AI-driven approach to designing, testing, documenting, and automating modern infrastructure using coding agents, digital twins, Git, GNS3, NetBox, telemetry, and real network devices. What if modern infrastructure could be designed, tested, and automated through natural language? In this episode, we feature Kamal Bhatt, Head of Value Driven Software Delivery at STORDIS, presenting his CLOUDFEST Masterclass on Infrastructure as Prompt — a new way of thinking about infrastructure automation in the age of AI coding agents. Kamal walks through the evolution of orchestration, from CLI and SNMP to SDN, REST APIs, Infrastructure as Code, and now AI-assisted workflows where prompts, skills, instructions, and MCP can help turn intent into infrastructure actions. This session explores how tools such as GitHub Copilot, GNS3, NetBox, telemetry systems, Git repositories, Draw.io, and real switches were combined in a proof of concept for AI-driven infrastructure operations. You will learn how AI agents can compare documentation with live or simulated network topologies, generate deviation reports, support digital twin workflows, identify ACL overlaps and IP conflicts, and even turn diagrams into simulated labs. The episode also looks honestly at the trust gaps that still need to be solved before AI-driven infrastructure automation can be used safely in production — including hallucinations, ambiguity, AAA, vendor differences, rollback strategies, and the need for guardrails. If you are interested in network automation, NetDevOps, AI infrastructure, digital twins, data center orchestration, or the future of Infrastructure as Code, this episode is for you. You will discover: How infrastructure orchestration evolved from CLI and SNMP to APIs and Infrastructure as CodeWhat “Infrastructure as Prompt” means in practiceHow AI coding agents can support infrastructure operationsWhy Git repositories matter for backups, generated code, and reference designsHow GNS3, NetBox, telemetry, and real switches can work together in an AI workflowHow hand-drawn diagrams and Draw.io files can become topology simulationsWhy digital twins and guardrails are essential before production useWhere the biggest trust gaps are in AI-driven infrastructure automation 00:00 Intro00:55 Evolution of orchestration: CLI, SNMP, SDN, REST, IaC01:58 From code to prompt03:03 What Infrastructure as Prompt means04:27 Proof of concept architecture06:44 Prompts, skills, instructions, and MCP07:39 GNS3, NetBox, telemetry, and real switches09:33 Why Git repositories matter12:07 Device skills and automated backups15:33 GNS3 REST API automation17:20 Comparing GNS3 topology with NetBox documentation19:03 Digital twins, GitHub issues, ACL overlaps, and IP conflicts21:28 Turning diagrams into GNS3 labs23:29 Trust gaps in AI-driven orchestration25:57 Digital twins, guardrails, and validation28:10 Q&A Presentation:https://stordis.com/wp-content/uploads/2026/04/Kamal-Krishna-Bhatt_Infrastructure-As-Prompt_Stordis-GmbH-.pdf Kamal Bhatt YouTube Channel:https://www.youtube.com/@UCGZUFgtdxAkUIyiS-YU9XpQ STORDIS:https://www.stordis.com Support:support@stordis.com

    Open-Source Operable SONiC | OCP Dublin 2025

    Recorded live at the OCP Regional Summit Dublin 2025, this candid session features Matthias Haag (Founder & CEO, UhuruTec) sharing what it really looks like to deploy Community SONiC for a production cloud platform — from the perspective of a network user, not a network admin. Matthias walks through the promise of vendor-neutral networking (a “Linux-like” hardware abstraction for switches) — and the friction points he hit when trying to operationalize Community SONiC: slow and flaky build pipelines, unclear failures and unpinned dependencies, missing release tagging/versioning, feature gaps like EVPN multihoming, and day-2 reliability issues such as SNMP container crashes and unexpected restarts. He then contrasts Community SONiC with commercial/enterprise SONiC distributions (including Broadcom’s), and ends with a clear call to action: a truly open, enterprise-ready SONiC with proper CI/CD, reproducible builds, platform testing, sane releases/tags, and more upstream collaboration — with fewer “politics” slowing down key contributions. 00:00 Music / opening00:11 Intro: who Matthias is and the perspective he brings (user vs. admin)00:36 Project context: why NOS/switching choices matter for a cloud platform00:46 Why SONiC and why starting with Community SONiC03:43 Hardware bring-up + setting up a custom build approach04:18 Build realities: long runtimes, caching effort, failure loops04:59 Versioning challenges: build identification, consistency, missing tags/releases05:56 Pipeline reliability concerns: “rerun works” and dependency/pinning issues06:50 Design goals: target fabric architecture + connectivity requirements07:12 Feature gaps: key capabilities missing or delayed upstream07:32 Operational stability: monitoring/service reliability pain points08:06 Boot/bring-up issues: unexpected states and disruptive fixes08:18 Hardware visibility: intermittent missing interface/transceiver info08:43 Port configuration: workarounds and manual adjustments09:06 Config errors: “applied but errors” situations that reduce confidence09:33 Unexpected restarts after configuration changes10:06 Day-2 usability: split tools for different layers and admin workflow friction10:34 Production readiness: where it’s okay today vs. where it’s still risky11:23 Enterprise/commercial comparison: features, stability, QA, polish12:04 The “server-world” analogy: openness vs. ecosystem constraints/lock-in risk13:13 Call to action: truly open “enterprise” SONiC (releases, CI/CD, testing, UX)18:06 Q&A: bringing issues upstream; tags existed before, then stopped19:25 Vendor discussion: shifting toward stronger community participation21:23 Community feedback: upstream-first collaboration vs. fragmented forks 📬 Questions or support: support@stordis.com | www.stordis.com Let’s get social 💻 Blog: stordis.com/blog/ 📘 Facebook: facebook.com/people/STORDIS-GmbH/100057058555819/ 📸 Instagram: instagram.com/stordis_open_networking/ 👥 LinkedIn: linkedin.com/company/stordis/ 🐦 X: twitter.com/STORDIS_GmbH/
