Virtual Machine Protection
La mancanza di fiducia è il piùgrande scoglio da superare per l’adozione del cloud
Microsoft vuole che i clienti sianotranquilli sulla sicurezza dei propridati

Virtual TPM & Shielded VMs
• Shielded Virtual Machines possono girare solo su specifici host designati come owners della VM
• Shielded Virtual Machines vengono criptate con BitLocker in modo che solo l’host designato possa eseguire la VM
• E’ possibile convertire unavirtual machine in funzione in una Shielded Virtual Machine

Quarantine of flapping nodes
Resiliency
Il nodo viene messo in quarantena se lascia il
cluster in modo inatteso per tre volte in un’ora
Le VM ospitate dall’host messo in quarantena
vengono migrate in modo gestito
Protection
Nodi che manifestano problemi vengono messi in
quarantena e vengono esclusi dal cluster
Previene che “flapping nodes” influenzino negativamente
gli altri nodi e tutto il cluster
Control
Non più del 25% dei nodi possono essere messi in
quarantena contemporaneamente
I nodi vengono esclusi dal cluster per 2 ore

Per Guest Windows Server TP4/Windows 10, è possibile
aumentare o diminuire la memoria assegnata alla VM
mentre è in funzione
Network
Network Adapter possono essere aggiunte o rimosse da
Gen 2 VM mentre sono in funzione
Replicated Disks
Quando viene aggiunto un virtual hard disk a una VM in replica
– il disco viene automaticamente aggiunto al not-replicated set.

Virtual Machine Upgrade
Compatibility mode: Quando una VM viene migrata su un host Windows Server 2016 TP4, rimane in modalità Windows Server 2012 R2 compatibility.
L’upgrade della VM è un task separato rispetto all’upgrade dell’host.
Le VM possono essere riportate indietro fino a che non vengono manualmente aggiornate di versione
Update-VMVersion vmname
Una volta aggiornate le VM possono avere i vantaggi delle nuove featore di TP4 Hyper-V.
Servicing model: VM drivers (integration services) devono essere aggiornati.
I VM drivers aggiornati vengono distribuiti al guest OS via Windows Update.

• No nuovo hardware
• No downtime
• Possibilità di roll-back sicuro, se necessario
• Fino a che non viene seguito Update-ClusterFunctionalLevel
• Cluster Functional Level = 8 (Windows Server 2012 R2)
