Infrastructure servers are servers that host core services required to run an IT environment. They provide centralized resources and capabilities that other systems and users rely on, rather than delivering end-user applications. These servers are designed for reliability, scalability, and security to support ongoing operations.

Common roles include domain controllers for authentication, DNS and DHCP for name resolution and address management, and file/print servers for centralized storage and access. Virtualization hosts run multiple virtual machines. Other frequent roles are backup and recovery, monitoring and management, patch management, load balancing, and certificate services. In larger environments, separate servers may perform these roles to improve resilience.

Deployment architectures range from on-premises hardware to virtualized and cloud-integrated stacks. High availability is achieved through clustering, redundancy, and geographically dispersed data centers. Hybrid and multi-cloud configurations are common, with some services delivered as managed cloud offerings and others on private infrastructure. Automation and configuration management tools help deploy and maintain infrastructure servers at scale.

Security and operations emphasize hardening, timely patching, least-privilege access, encryption, network segmentation, regular backups, and disaster recovery planning. Continuous monitoring, logging, and alerting support incident detection and response. Good documentation and change control aid auditing and stability.

In summary, infrastructure servers form the backbone of modern IT environments, providing essential services that underlie applications, networks, and user productivity.
