The cloud lives in the basement — what Cloud Native means for the SOPTIM Projects division

What sounds like an amusing contradiction at first actually describes precisely and aptly how we approach modern IT technologies in SOPTIM’s Projects division. Because Cloud Native does not inherently mean that applications have to run in a public cloud. Rather, the term stands for a highly innovative approach to designing, developing, and automating software — regardless of where the infrastructure ultimately runs.

Cloud Native: more than just an operating model

The demands placed on modern software solutions in the energy industry have changed radically over recent years. Applications must be flexible, granularly scalable, and maximally resilient. At the same time, our customers expect systems that can be operated in a platform-independent and automated way. The Cloud Native stack is no longer a “nice-to-have” today — it is a core part of how we deliver projects.

This is by no means about reinventing the wheel for every technical challenge. On the contrary: Cloud Native is fundamentally built on the principle of standing on the shoulders of giants. We use established open-source technologies and standards that are continuously developed by a global community under the umbrella of the Cloud Native Computing Foundation (CNCF), with rigorous governance and extremely high quality standards. This protects against the notorious “Not Invented Here” syndrome and guarantees future-proof software components that global digital ecosystems rely on today.

The critical infrastructure environment and the sovereignty paradox

While the direct path to the public cloud makes absolute sense in standard product environments — such as the SOPTIM Elements platform — different regulatory rules often apply in the Projects division, particularly in the context of critical infrastructure (KRITIS).

Furthermore, a pure dependency on public cloud in the critical infrastructure space creates a dangerous technological paradox: a system responsible for controlling and stabilizing the power grid cannot, in a crisis situation, depend on whether an external, global infrastructure is reachable and functioning.

The Projects division’s answer: full digital sovereignty.

Because we use the same proven CNCF technologies as the major cloud providers, we can run them seamlessly in our own SOPTIM data center or in hybrid environments. Our customers benefit from state-of-the-art operating principles while retaining, together with us, full control over their business-critical systems and data.

Kubernetes and the freedom for hybrid scenarios

The uncontested technological foundation of this approach is Kubernetes as the de facto standard for container orchestration. The platform handles automated container management, ensures applications remain continuously available, recovers from failures autonomously, and flexibly adjusts resources to meet changing demands.

The decisive advantage for our tailor-made projects is cloud independence. Without vendor lock-in, an entire Kubernetes cluster can be deployed with minimal effort wherever the customer needs it — whether on-premises, with a sovereign European cloud provider, or in a hybrid combination. The software stays identical, highly portable, and flexible.

Cloud Native is above all a mindset

Technology alone is not enough. Cloud Native also requires a fundamental shift in how teams think. The classic anti-pattern of “works on my machine” is a thing of the past.

Architecture, automated monitoring, resilience, and future operability must be considered from the very first line of code. Developers must think in terms of distributed systems:

• Can multiple instances of this application run simultaneously without blindly writing to the same database instance?
• How does the service behave within the context of the entire cluster?
• Are all components automatically testable and observable?

This new, holistic way of thinking breaks down old silos and produces extremely robust, long-lived software solutions — both internally and for our customers.

Shaping the future together

At SOPTIM, we never stand still and continuously expand our deep in-house expertise. Our project teams are currently working on highly specialized initiatives such as “Dynamic Clusters 2.0” for intelligent resource optimization, as well as the provisioning of highly secured, Cloud Native-based development environments.

For SOPTIM’s Projects division, Cloud Native is far more than a short-lived trend. It is our commitment to the market: to build state-of-the-art, resilient, and future-proof solutions that support the energy transition digitally — whether the cloud ultimately runs on virtual servers, in a hybrid cloud, or completely sovereignly, right there in the basement.
