Today we are open-sourcing the Private LLM and Chat UI providers for Platform Mesh, together with a step-by-step tutorial that runs the entire demo on a single laptop in about 35 minutes.

Platform Mesh turns Kubernetes operators into managed services: a provider writes an operator once, registers it through Platform Mesh, and every customer reaches it through their own workspace, never touching the cluster where the operator runs. What we want to highlight with this example is composition. Private LLM and Chat UI are completely independent (different teams, different repos, different operators) but they compose into a working private chatbot through a single Secret contract. The customer wires them together; the provider teams never have to coordinate.

Private LLM runs a llama.cpp inference server. The customer creates an LLMInstance and the provider hands back a Secret with an OpenAI-compatible endpoint. Chat UI deploys a per-tenant Open WebUI. The customer creates a ChatUIInstance pointing at any OpenAI-compatible Secret, including the one Private LLM just created.

Try it on your laptop. The full tutorial is published as part of the Apeiro Reference Architecture documentation. Everything runs inside a single Kind cluster, yet the logical layers match the production setup exactly. You play both roles: first the platform team, then the customer.

Our presentation at the Role of Open Source to advance the Sovereign Cloud Edge Continuum side event of the Summit on European Digital Sovereignty has been uploaded to the NeoNephos YouTube channel!

You'll see representatives from member organizations of NeoNephos introduce the audience through interactive talks to its projects and the value NeoNephos provides to the sovereign cloud native ecosystem.

At the 25th ACM Internet Measurement Conference (IMC) 2025, Arno Uhlig presents the paper "The SAP Cloud Infrastructure Dataset: A Reality Check of Scheduling and Placement of VMs in Cloud Computing". In this paper, we analyze telemetry data from 1,800 hypervisors and 48,000 Virtual Machines (VMs), which are part of the SAP Cloud Infrastructure, covering a 30-day observation period. We make the dataset publicly available since reproducible research is at the heart of ApeiroRA. This is the first public dataset providing VM workload of a major cloud infrastructure. The dataset already informed the development of Cortex, a novel placement and scheduling solution for workloads of the entire cloud-edge continuum. We hope that the SAP Cloud Infrastructure Dataset also serves as a reference dataset to advance future research on scheduling of compute, storage, network, and GPU workloads.

ACM IMC is a highly selective venue for the presentation of cutting-edge measurement-based research in data communications. This year's conference focuses on advancing the state of the art in the collection, usage, analysis, and sharing of network measurements for the research community. Our paper contributes to reproducibility of research as well as sharing of data.

This work is the result of a research collaboration between SAP and the Chair of Distributed and Networked Systems at TU Dresden.

NeoNephos Foundation

The Linux Foundation Europe announced the official launch of the NeoNephos Foundation. With SAP's continuous commitment to open innovation, we are proud to announce that we are a founding member along with Clyso GmbH, Cyberus Technology, Deutsche Telekom AG, STACKIT, TNO-ECOFED, and 23 Technologies GmbH. NeoNephos serves as a collaborative environment that accelerates the development of market-ready open-source innovations. Its goal is to reduce dependency on non-European platforms, enhance cybersecurity, and enable businesses to scale with confidence.

NeoNephos, one of the first open-source outcomes of the IPCEI-CIS EU investment, emerges as a response to the demand for secure, scalable, and transparent cloud solutions that support European goals of digital sovereignty. As European enterprises and public institutions face growing regulatory requirements and the need for greater control over their cloud infrastructure, NeoNephos provides a trusted foundation for open, interoperable, and future-proof solutions.

SAP is reinforcing its commitment to this vision by donating several of our flagship open source projects like Gardener, Garden Linux, IronCore, CobaltCore, Greenhouse, Open Micro Frontend Platform, Open Resource Discovery, Open Component Model, Open Managed Control Plane and Platform Mesh. ApeiroRA, a key contributor, therefore plays a pivotal role in underpinning the technical robustness and enterprise readiness of NeoNephos.

SAP's active participation in NeoNephos  sets a new industry benchmark for innovation in sovereign cloud technologies while delivering real economic and strategic value to the European digital economy.

We are thrilled to be part of a journey that advances the objective of a collaborative, secure, and interoperable cloud and edge ecosystem in Europe and welcome additional members, contributors, and collaborators to get involved in our efforts.
