Key Points – Security model requiring explicit verification for network access – Does not assume trust based on network location – Verifies access continuously or per request – Treats internal and external traffic with equal scrutiny – Emphasizes continuous verification,…
Key Points – Handles events as a stream over time – Used in data pipelines and messaging architectures – Supports real-time processing and integration – Common in cloud and distributed systems – Enables asynchronous producer-consumer patterns – Allows systems to…
Key Points – Refers to a general geographic area – Used for spatial organization and planning – Can describe physical, operational, or administrative areas – Meaning depends on context – Common misuse: assuming the term always implies a cloud or…
Key Points – Intent Based Networking translates business or operational intent into network configuration and policy – Network management is driven by declared intent and automated enforcement – Used in operational and architecture contexts – Operators express desired outcomes rather…
Key Points – Used for pointing and alignment – Often paired with azimuth and elevation – Common in satellite and tracking applications – Depends on reference frame and target geometry Definition Look Angle is the directional angle used to point…
Key Points – Abstracts server management from developers – Executes code on demand – Often scales automatically with request load – Used in event-driven cloud applications – Charges typically based on execution time and resources consumed – Cold starts and…
Key Points – Service Degradation represents reduced service performance without full outage – Defined for network and system contexts – Used in operational and architecture monitoring – Distinguishes partial impairment from complete service failure Definition Service Degradation is a reduction…
Key Points – Traffic Mirroring duplicates packets or flows to a mirrored output while leaving the primary traffic path in place – Used for observability and traffic analysis in live networks without forcing the monitoring system into the data path…
Key Points – Data Plane is the operational execution layer that moves traffic or processes data after control decisions are made – It is separate from the control plane, which makes policy decisions – Used in routers, switches, firewalls, and…
Key Points – Uses Ethernet as the base communication technology – Adds industrial timing, topology, or resilience requirements – Supports plant-floor and machine-level networking – Interoperates with automation and control systems – Provides standardized communication across machines, controllers, sensors, and…
