AI SRE & DevOps Glossary
Plain-language definitions for the key terms in Agentic AI, AI SRE, AIOps and cloud-native engineering.
What Is a Postmortem in Software Engineering?
A postmortem is a structured review of a production incident - documenting what happened, why it happened, and what systemic changes will prevent recurrence.
Read MoreWhat Is AI in Production?
AI in production means deploying AI systems that operate autonomously in live environments. Learn the reliability, monitoring, and trust considerations that come with it.
Read MoreWhat Is OOMKilled?
OOMKilled means Kubernetes terminated a container because it exceeded its memory limit. Learn what causes it, how to investigate it, and how to fix it.
Read MoreWhat Is Site Reliability Engineering (SRE)?
SRE applies software engineering to operations - using automation, measurement, and systematic analysis to keep production systems reliable.
Read MoreWhat Is Incident Investigation?
Incident investigation is the diagnostic phase of incident response - the work between an alert firing and a remediation being applied.
Read MoreWhat Is Kubernetes Alert Investigation?
Kubernetes alert investigation is the process of finding the root cause of a Kubernetes failure after a monitoring alert fires - from log collection to root-cause diagnosis.
Read MoreWhat Is Alert Fatigue?
Alert fatigue is when engineers begin ignoring alerts due to noise. Learn why it happens, how it develops, and how to reduce it.
Read MoreWhat Is an AI SRE Agent?
Learn what an AI SRE agent is, how it works, and why it changes incident response for Kubernetes teams
Read MoreWhat Is Engineering Toil?
Engineering toil is repetitive, manual operational work that scales with system growth. Learn how SRE teams measure it and why reducing it matters.
Read MoreWhat Is OpenTelemetry?
OpenTelemetry is the open-source standard for collecting metrics, logs, and traces from distributed systems - vendor-neutral and CNCF-hosted.
Read MoreWhat Is a Kubernetes HPA?
A Kubernetes HPA (Horizontal Pod Autoscaler) automatically scales pod count based on resource utilisation. Learn how it works and what KubeHpaMaxedOut means.
Read MoreWhat Is Kubernetes?
Kubernetes is the open-source container orchestration system that automates deployment, scaling, and management of containerised applications. Learn how it works.
Read MoreWhat Is On-Call in Software Engineering?
On-call is the rotation in which engineers take scheduled responsibility for responding to production alerts. Learn how it works and how to design it sustainably.
Read MoreWhat Is Observability?
Observability is the ability to infer the internal state of a system from its external outputs. Learn the three pillars and how observability underpins incident investigation.
Read MoreWhat Is AIOps?
AIOps applies machine learning to IT operations - reducing alert noise and detecting anomalies. Learn what it does well and where it falls short.
Read MoreWhat Is MTTR?
MTTR - Mean Time to Repair - measures how fast a team restores service after a production failure. Learn how to calculate and reduce it.
Read MoreWhat Is Root Cause Analysis (RCA)?
Root cause analysis identifies the fundamental reason a failure occurred - not just the symptom, but the underlying cause. Learn the methods used in software engineering.
Read MoreWhat Is CrashLoopBackOff?
CrashLoopBackOff is a Kubernetes pod status indicating a container is repeatedly starting and crashing. Learn what causes it and how to investigate it.
Read MoreWhat Is Agentic AI in DevOps?
Understand agentic AI in DevOps - how autonomous AI systems differ from chatbots and where they create real operational value.
Read MoreWhat are production systems in software engineering?
What are production systems in software engineering?
Read MoreWhat Is Multi-Agent Incident Response?
Multi-agent incident response uses multiple specialised AI agents working in parallel to investigate production failures faster than any single agent can.
