Linux
Unix-like operating system for servers, appliances and developer hosts.
Linux is a kernel-based operating system commonly used on servers, virtual machines, containers and developer workstations. It provides the core process, storage and network services that run business applications.
Operational challenges include frequent kernel and package updates, differing distribution behaviours and the need for kernel-level tuning. These affect uptime, patch windows, permissions, logging and how system services are managed.
Audit and monitoring for Linux systems
Capture Linux activity, configuration and process events to support review and investigation.
Linux administration and automation
Centralise user, patch and service lifecycle tasks and automate routine workflows to reduce manual intervention and keep configurations consistent.
Where Linux fits
Linux connects to storage, network services, identity systems and orchestration layers using standard protocols. It often coexists with other operating systems in mixed estates and hosts application stacks, containers and automation tooling.
It must be considered when planning patching, access control, backups and observability because kernel and system service behaviour determine restart needs, log formats and security boundaries. Teams should account for distribution differences and kernel upgrades when defining operational processes.
