Resilient data center operating models – balancing reliability, efficiency and regulation

Data centers are at the heart of the digital economy — and therefore also at the center of growing uncertainties. Cyberattacks are becoming more sophisticated. Power grids are coming under pressure from peak loads and extreme weather events. At the same time, global supply and network chains are increasing operational vulnerability.

In this environment, it is clear that traditional approaches to data center operations are no longer sufficient. A modern data center operating model must now do far more than simply manage infrastructure. What is needed are resilient structures that holistically safeguard operations, organizations, and technology.

Against this backdrop, industry experts discussed the future of resilient data center operating models at Data Center Nation in Milan.

The panel discussion focused, among other things, on the following topics:

• How must data center operating models evolve to become resilient against both physical and digital threats?
• What role do automation, AI, and real-time monitoring play in ensuring resilience and recoverability in data center operations?
• How can the right balance between efficiency, cost, and resilience be achieved in the data center operating model?
• What impact do regulatory requirements have on resilient data center operating models?

These questions led to five key findings.

For a long time, the focus in data centers was primarily on physical infrastructure such as servers, storage, and networks. Today, this focus is shifting significantly toward the overall data center operating model.

A modern operating model encompasses much more:

• organisation of operational teams and responsibilities
• monitoring, automation and escalation processes
• security and contingency plans
• interaction between on-premises, cloud and edge environments
• governance and regulatory requirements

This makes it clear: resilience in the data center does not arise from individual technologies, but from the interplay of the entire operating model.

As modern IT infrastructures become increasingly complex, automation is becoming a key component of the data centre operating model.

The focus is shifting from mere fault prevention to active optimisation of resilience and recovery:

• automated failover between sites
• self-healing infrastructures
• AI-supported real-time anomaly detection
• predictive maintenance for critical components

As a result, data centre operations are evolving from a reactive to a proactive model.

At the same time, however, a new challenge arises: the greater the level of automation, the more important transparency, control and robust security mechanisms become within the operational model.

A resilient data center operating model is always an economic balancing act.

Greater resilience typically means:

• higher redundancy
• additional infrastructure
• more complex operational processes

This is balanced against efficiency, cost and scalability objectives. Consequently, many organisations are increasingly focusing on:

• tiered criticality models for applications
• targeted protection of business-critical systems
• flexible cloud and hybrid architectures
• risk-based investment decisions

At the core of this is a fundamental question: How much availability does the data center operating model require — and what level of cost is justified to achieve additional resilience?

In addition to technical and economic factors, regulatory requirements are increasingly shaping data center operating models.

Frameworks such as the NIS2 Directive or the Digital Operational Resilience Act (DORA) set out binding minimum requirements for the security and operational resilience of digital infrastructures.

This fundamentally changes the role of resilience:

• from a competitive factor
• to a basic regulatory requirement in data centre operations

This raises a strategic question for businesses: do investments that go beyond compliance requirements still offer competitive advantages – or do they primarily serve to minimise risk?

The discussion at Data Center Nation in Milan clearly shows that traditional data center operating models are reaching their limits in the face of growing physical, digital and regulatory challenges.

Future-proof models are based on:

• consistently resilience-oriented data center operating models
• integrated security and operational strategies
• automated, data-driven processes
• hybrid infrastructure architectures
• clear incorporation of regulatory requirements

This makes it clear: resilience is not a state, but a continuous principle of modern data center operating models – and thus their central design element.
