Fog Computing
Dezentrale Recheninfrastruktur, die Cloud-Ressourcen näher an den Rand des Netzwerks bringt.
Es dient dazu, Latenzzeiten zu minimieren und Bandbreite zu sparen, indem Daten lokal vorverarbeitet werden, bevor sie in die Cloud gesendet werden. Dies ist besonders wichtig für das Internet der Dinge (IoT) und Industrie 4.0. Fog Computing bildet eine Hierarchie, die Clouddienste bis an den Netzwerkrand verlängert.

🌫️ A way to organize tiny computers in a neighborhood so they can help each other out and talk to the big cloud together, instead of everyone working alone.
🤓 Expert Deep Dive
## Edge vs. Fog: The Key Difference
- Edge Computing: Happens on the device or the gateway it's directly plugged into. Focus: Low latency and local autonomy.
- Fog Computing: Happens in the local network infrastructure (routers, switches, micro-data centers). Focus: Distributing resources across many devices and managing the network flow.
Think of the Edge as the 'last mile' and the Fog as the 'local neighborhood center' that supports it.
❓ Häufig gestellte Fragen
Was ist der Unterschied zu Cloud Computing?
Fog Computing verarbeitet Daten näher am Entstehungsort, während Cloud Computing zentralisiert in Rechenzentren stattfindet.
