Typen von EC2 Instanzen
Amazon EC2 Instanzen sind in drei Gruppen unterteilt. Standard, High-CPU und High-Memory. Standard Instanzen sind so ausgestattet, dass sie allen Anforderungen von gewöhnlichen Anwendungen gerecht werden. High-CPU Instanzen verfügen über verhältnismäßig mehr Prozessoren als Arbeitsspeicher und sind auf rechenintensive Anwendungen ausgelegt. High-Memory Instanzen hingegen verfügen über mehr Arbeitsspeicher und sind für Anwendungen mit einem hohen Datendurchsatz, wie z.B. Datenbanken und Caching, ausgelegt.
Bei der Auswahl einer Instanz kann somit jedem Server seine eigene Instanz zugewiesen werden. Für einen Webserver wird z.B. eine weniger leistungsstarke Instanz benötigt als für einen Datenbankserver.
Verfügbare Instanz-Typen
