MODULE 1
NETWORK MODEL
Traditional Network Computing : server con applicazioni e dati
- sistema operativo del server
- sistema operativo del client
- protocollo di rete comune
Client Server Computing : il server gestisc l'accesso ai dati
- un client per le richieste delle applicazioni
- un front-end server per la gestione delle richieste del client
- un back-end server che gestisce il DB
Network Computing (Java) : client senza HD ,le applicazioni girano nella ram del client
- universal network client (Java)
- application server
- universal data server
Application Server Computing : applicazioni eseguite sul server
- s.o. multiutente
- protocollo di presentazione (protocollo ICA)
- client software
- gestione centralizzata della applicazioni e dei client
Esistono due tipi di dispositivi per gli utenti : Fat e Thin client ,rispettivamente : pc completi di hd ,ram ecc ;pc senza hd ,slots di espansione ecc.
KEY BENEFITS OF DEPLOYING METAFRAME
Is approach to application server computing offers business benefits in four keys areas :
