\n Initial Situation & Client Profile <\/h2>\n <\/div>\n
\n <\/div>\n
\n How do you provide a high-performance, secure and highly available IT infrastructure while simultaneously meeting complex requirements from government, industry and research?<\/p>\n

The Deutsche Energie-Agentur GmbH<\/strong> (dena)<\/strong> is a federally owned organization that delivers key projects at the intersection of energy, climate protection and public administration<\/strong>. This involves highly complex digital solutions that require a stable and secure IT foundation.<\/p>\n

dena is responsible for numerous web projects, applications or digital platforms that must meet demanding requirements for security, availability and scalability. With around 700 employees<\/strong> and multiple locations<\/strong>, the organization needs an IT foundation that runs reliably while remaining flexible enough to support future requirements.<\/p>\n

Over time, the existing infrastructure could no longer meet these demands. In particular, limitations in performance, adaptability and the continued development of systems highlighted the need for a new foundation. This success story shows how dena, together with SITS, modernized its IT landscape and built a high-performance platform for the reliable operation of business-critical applications<\/strong>. <\/div>\n <\/div>\n

\n The Challenge <\/h2>\n <\/div>\n
\n Transforming a complex IT landscape for the future <\/div>\n
\n dena faced the challenge of fundamentally modernizing its existing infrastructure.<\/p>\n

The objective was the complete migration<\/strong> of all projects into a modern Kubernetes-based cluster environment<\/strong> within a very tight timeframe.<\/p>\n

In addition, heterogeneous applications and systems had to be consolidated into a unified platform without disrupting ongoing projects.<\/p>\n

The key challenge was to simultaneously ensure migration success, operational reliability and future scalability while maintaining consistently high requirements for availability and security.<\/strong> <\/div>\n <\/div>\n

\n Implementation <\/h2>\n <\/div>\n
\n Seamless migration despite high complexity <\/div>\n
\n Together with dena, SITS developed a modern infrastructure platform<\/strong> that meets key requirements for performance, stability and security.<\/p>\n

The existing system landscape was fully migrated to a Kubernetes cluster environment within a short period of time<\/strong>. At the same time, applications based on different technologies were successfully integrated into the new platform.<\/p>\n

A critical success factor was the close collaboration with multiple external service providers, combined with the high responsiveness demonstrated throughout the project.<\/p>\n

SITS stood out through its technical expertise and structured approach, even during critical project phases.<\/p>\n

In addition, a stable operational framework was established, including reliable support services and an effective emergency support model. <\/div>\n <\/div>\n

\n The Result <\/h2>\n <\/div>\n
\n Greater performance, stability and flexibility: <\/div>\n
\n With the new platform, dena was able to place its digital projects on a reliable technical foundation. Applications now run in a modern cluster environment<\/strong> designed for high availability and future growth.<\/p>\n

At the same time, the organization benefits from faster loading times<\/strong>, greater flexibility<\/strong> when implementing new initiatives, and an infrastructure<\/strong> that operates reliably even in a highly demanding environment<\/strong>.<\/p>\n

The difference is particularly noticeable in day-to-day operations. Where previously different technological requirements and extensive coordination efforts added complexity, there is now a unified environment that simplifies operations and is better equipped to accommodate new requirements. This provides stability for ongoing business activities while creating the flexibility needed to launch new projects more efficiently and in a more structured manner.<\/p>\n

For dena, this means one thing above all: greater reliability, greater operational flexibility, and a platform that is not only fit for today, but fully prepared to support future requirements as well.<\/strong> <\/div>\n <\/div>\n
