System Maintenance
System Maintenance refers to the ongoing processes and practices involved in keeping a software system or IT infrastructure operational, secure, and efficient after deployment. It includes activities such as applying updates, monitoring performance, fixing bugs, and ensuring compliance with requirements. This skill is critical for maintaining system reliability, availability, and longevity in production environments.
Developers should learn system maintenance to ensure the long-term health and stability of deployed applications, particularly in DevOps or site reliability engineering (SRE) roles. It is essential for minimizing downtime, addressing security vulnerabilities through patches, and adapting systems to changing user needs or technological advancements. Use cases include maintaining legacy systems, managing cloud infrastructure, and supporting continuous delivery pipelines.
