vCloud Director Networking
1.
External Networks
2.
Organization Networks
3.
vAPP Networks.
Organization networks and vAPP networks can be configured in
one of three different configurations
·
Direct-Connected to higher network level
·
NAT-Connected to higher network level
·
Internal only (no connections to higher networks
)
vCloud Director can provide dynamic networks to customers
without damaging the stability of corporate IT network systems.
“Network team need a
constant stable network in contrast customer needs rapid changing networks.”
External Networks :-
·
External Networks are use to provide a
connection outside the cloud usually to the internet.
·
External Networks are built off of vSphere port groups
·
Organization networks can connect to external
networks directly or routed using
vShield.
·
Several external networks can co-exist on the
same physical LAN when separated by VLANs.
·
External networks are logical, differentiated
networks based on vShere port groups.
·
External network need not have connection to the
internet; it is external to vCloud orgs.
·
External networks can be used for VPN,
Connection to backup servers and MPLS to connect sites at different locations.
Organization Networks:-
·
Direct –Connected
·
NAT-Connected
·
Internal
“Do not confuse external organization networks with external
(provider) networks .An external organization network provides network services
for only one organization. An external network that is created at the provider
level is one which uses vSphere port groups and provides connectivity for
multiple organizations.”
Organization administrators cannot create organization
networks. vCloud Administrators has to provide external address to be used with
IP forwarding.
vAPP neteworks:
Fenced network is a method of configuring vAPP networks
.fenced networks allow two identical vAPPs to run with the same internal
networks addresses.
