The company also provides additional server infrastructure across multiple European and U.S. locations.

This geographic distribution allows customers to deploy applications closer to their users and build geographically redundant infrastructure.

European Infrastructure and Data Sovereignty

One of IONOS's major competitive advantages is its European infrastructure and strong focus on data sovereignty.

The company operates significant infrastructure in Germany and other European countries and positions IONOS Cloud as a provider for organizations that require greater control over where their data is stored and processed.

This can be particularly important for:

European businesses
Government organizations
Financial services
Healthcare
Enterprise applications
Organizations with strict data residency requirements

IONOS's European infrastructure is also attractive to companies looking for alternatives to U.S.-based hyperscale cloud providers.

Data Center Security

Security is a major component of IONOS infrastructure.

The company states that its data centers are ISO 27001 certified, providing a recognized information-security management framework.

Depending on the facility and service, IONOS data centers also use:

Physical access controls
24/7 security monitoring
Video surveillance
Biometric authentication
Redundant power
UPS systems
Emergency generators
Redundant network connectivity
Fire protection systems

IONOS's Frankfurt data center infrastructure, for example, includes ISO 9001, ISO 27001, PCI-DSS, and other relevant certifications through its data center environment.

Network Infrastructure

IONOS operates a large network infrastructure designed around redundant connectivity and high availability.

Its cloud infrastructure uses multiple network providers and redundant networking components to reduce the impact of individual network failures.

IONOS also provides private networking, load balancing, firewall policies, DDoS protection, and other network services that allow customers to create more complex application architectures.

Security and DDoS Protection

IONOS provides multiple security layers across its server and cloud products.
