Clear explanations of IT concepts, protocols, architecture and enterprise technologies.
Understand the technology behind your infrastructure.
IT monitoring is the continuous observation of systems, applications, and infrastructure to ensure performance, availability, and security. Learn how it works, key metrics, alerting, and monitoring vs observability.
A cluster is a group of interconnected computers (nodes) that work together as a single system for higher availability, performance, and scalability than one machine. This explainer covers how clusters work, the main types (high-availability, load-balancing, HPC, storage), quorum and fencing, use cases, and limits.
