ITtaristu

ITtaristu is a term used in the Estonian information technology sector to denote information technology infrastructure—the collection of hardware, software, networks, data storage, and related services that support information systems in organizations. The term combines IT with taristu, meaning infrastructure, and is used to discuss design, procurement, deployment, and management of these resources.

Components and layers: data centers and server hardware; networks (LAN, WAN, wireless); storage systems; virtualization and cloud resources; software platforms; endpoints and user devices; security and identity services; monitoring, backup, and disaster recovery. ITtaristu encompasses both on-premises assets and cloud-based resources, often realized in hybrid or multi-cloud configurations.

Responsibilities: architecture planning and capacity management; provisioning and automation (infrastructure as code); performance monitoring; incident response; data protection; compliance with security and privacy standards. Teams work across procurement, operations, and security to ensure availability, integrity, and performance.

Standards and practices: ITIL-based service management; ISO/IEC 27001 for information security; ISO/IEC 20000 for service management; alignment with cloud standards and regulatory frameworks in the European Union. Common approaches include virtualization, software-defined networking, and IaC.

Trends: increasing use of cloud-native tools, automation, and AI-driven operations; emphasis on resilience, disaster recovery, and zero-trust security; growing importance of edge computing and data sovereignty in distributed environments.
