Lambda architecture

Sovereign observability is now essential as organizations operate Kubernetes across fragmented multi-cloud environments. Traditional monitoring approaches fail when logs and metrics cannot leave their originating region due to compliance and data-residency constraints. This architecture solves the challenge by decoupling storage from querying: each cloud environment writes logs and metrics to its own sovereign object storage while a central observer cluster queries them on demand. Leveraging Prometheus, Thanos, Loki, and Promtail, the system provides global visibility, secure mTLS communication, isolated buckets, and a unified Grafana experience — all without violating sovereignty rules.

In December 2025, T-Systems advanced Catena-X adoption in Asia through two key events: the Catena-X Supplier Onboarding Day in Tokyo and the Global Data Spaces Roundtable in Beijing. From practical supplier onboarding to large-scale automotive pilots in China, discussions focused on regulatory pressure, data sovereignty, and secure cross-company data exchange. Together with partners such as Siemens, BMW Group, BASF, and Flex, T-Systems demonstrated how trusted dataspaces enable scalable, compliant collaboration across global automotive value chains.

T-Systems has launched Connect & Integrate “Developer edition”, a streamlined environment designed to accelerate Catena-X application development. By removing barriers such as connector setup, compliance alignment, and semantic validation, the platform provides out-of-the-box connectivity with Catena-X–compliant APIs, guided workflows, and built-in compliance tools. Developers gain immediate access to secure, standardized data exchange without managing complex infrastructure, enabling them to focus on building innovative solutions across key use cases like traceability, carbon footprint, and demand management. Positioned as an innovation catalyst, the “Developer edition” empowers startups, integrators, and enterprises to rapidly deliver production-ready applications and drive Catena-X adoption across the automotive value chain.
