servicesmaintenance

Servicesmaintenance is the term used to describe the ongoing set of activities required to keep a service delivering its intended functionality after deployment. It encompasses software applications, cloud services, APIs, and business processes, and includes preventive updates, security patches, monitoring, incident response, and performance tuning.

The objective is to maintain reliability, availability, performance, and security while controlling cost and risk. Maintenance is typically planned in formal change windows and includes versioning, configuration management, and decommissioning of outdated components.

Key activities include monitoring and alerting, patch management, version control, backups, disaster recovery testing, capacity planning, and routine testing of service interfaces. Change management and release management coordinate updates to minimize disruption. Preventive maintenance uses automation and analytics to anticipate failures.

Performance and availability metrics such as uptime, MTTR, change failure rate, and SLA compliance are used to assess effectiveness. Governance frameworks like ITIL, ISO/IEC 20000 guide processes, roles, and documentation. Security considerations include vulnerability management and audit trails.

Examples include maintenance of a web application, a cloud-based microservice, or an API gateway. The lifecycle intersects with design, deployment, operation, and retirement, and requires clear ownership, documentation, and stakeholder communication.
