Digital: Making business more agile and flexible

Agility and flexibility are the most important advantages of a digitalized economy and administration. Production processes and supply chains can be adapted in an agile way. The basis for this is the real-time analysis of machine, production and planning data with the help of big data and artificial intelligence (AI). This allows sub-processes to be controlled autonomously, so that employees can concentrate on strategic future developments.

To this end, T-Systems offers an extensive portfolio of coordinated ICT and network solutions. In addition to private and public cloud services, these include digital solutions for Industry 4.0, artificial intelligence or solutions for the metaverse. T-Systems integrates these into existing ICT infrastructures or builds completely new structures and operates them from scratch. Digital solutions tailored to specific business processes are also used so that companies can exploit the full potential of digitalization

Cloud Services: Comprehensive and sovereign cloud ecosystem

The comprehensive product portfolio includes the secure operation of classic ICT infrastructures, as well as migration to private cloud and public cloud environments. T-Systems offers customers access to and operation of a comprehensive cloud ecosystem. To this end, the experts collaborate with more than 500 prominent technology and industry partners and service providers, as well as numerous start-ups. These include, among others, AWS, Microsoft, and Google, technology providers such as Cisco, VMware, and NVIDIA, and software manufacturers such as SAP, Salesforce, Microsoft, Pega, and Palo Alto. T-Systems is Europe's RISE with SAP Premium Supplier and offers its own RISE-certified private cloud, operated in Germany and Europe. For customers with special requirements regarding data protection, data sovereignty, and compliance, T-Systems offers its own T Cloud Public (formerly Open Telekom Cloud), which enables full compliance with all requirements of the General Data Protection Regulation (GDPR). Or, in partnership with Google, the "T-Systems Sovereign Cloud powered by Google Cloud", specifically for the German market. 

With the Industrial AI Cloud, T-Systems extends this profile with a sovereign AI infrastructure from Germany. The platform is designed for demanding AI applications, offers extensive GPU resources, and targets companies, research institutions, and the public sector that want to use AI powerfully while adhering to European data protection and security standards.

T-Systems has more than 20 years of experience in the transformation and management of complex IT systems and employs over 3,000 cloud architects and experts worldwide. The heart of the cloud services is one of the largest and most modern cloud data centers in Europe, located near Magdeburg in Saxony-Anhalt. It is the highly secure hub of T-Systems' global cloud infrastructure. In addition, the worldwide production network comprises 11 highly secure twin data centers (Twin Cores) and strategic Global Delivery Centers (GDC) in India, Spain, Hungary, Brazil, and Slovakia, as well as smaller shoring hubs in Romania and Poland. With 1,600 data management and 1,500 AI experts, T-Systems delivers scalable end-to-end AI services, unlocking the full potential of AI—always secure, responsible, and compliant.

Security: ICT and OT systems intelligently protected

A secure infrastructure for ICT and operational technology (OT) is crucial for the economic success of a company. But cyberattacks on networks and software are becoming a major threat. Almost every day, there are attacks by cybercriminals who exploit vulnerabilities, install malware, steal passwords and complete digital identities, intercept sensitive data and blackmail their victims. The reason: IT architectures are often not designed to be secure enough to withstand professional hackers. Therefore, one of the most important challenges of digitization is to successfully protect IT and OT systems.

Connectivity as a foundation

As an integral part of Deutsche Telekom—one of the world's strongest brands—T-Systems International can offer its business customers a complete portfolio of IT and communications technology. This makes T-Systems one of the few providers worldwide capable of delivering ICT solutions from a single source, end to end.

Sustainably into the future

Deutsche Telekom is committed to balancing economic, social, and ecological aspects and pledges to act responsibly along its entire value chain. As the first DAX 40 company, Telekom is climate-neutral in its own operations across the entire Group. As a subsidiary, T-Systems is committed to climate-neutral business practices, strives for the circularity of products and services, and promotes diversity, equal opportunity, and inclusion. As an IT and digitalization service provider, T-Systems supports companies with green technologies, green cloud services, smart logistics, or the analysis of IoT data to drive digital growth while simultaneously promoting sustainability and environmental protection.

Lived ecological responsibility includes ongoing measures to improve energy efficiency and promote the circular economy in cloud computing and data centers. T-Systems is committed to continuously improving the sustainability of its own data centers. The long-term goal is climate-neutral data centers that supply themselves on a net basis through an intelligent interplay of renewable generation, storage, and flexible consumers.
