<title>Basic and Advanced Networking</title>
|
|
<para>&PRODUCT; provides two styles of networking:.</para>
|
|
<formalpara>
|
|
<title>Basic</title>
|
|
<para>For AWS-style networking. Provides a single network where guest isolation can be provided
|
|
through layer-3 means such as security groups (IP address source filtering). </para>
|
|
</formalpara>
|
|
<formalpara>
|
|
<title>Advanced</title>
|
|
<para>For more sophisticated network topologies. This network model provides the most
|
|
flexibility in defining guest networks, but requires more configuration steps than basic
|
|
networking.</para>
|
|
</formalpara>
|
|
<para>Each zone has either basic or advanced networking. Once the choice of networking model for a
|
|
zone has been made and configured in &PRODUCT;, it can not be changed. A zone is either
|
|
basic or advanced for its entire lifetime.</para>
|
|
<para>The following table compares the networking features in the two networking models.</para>

<para>The two types of networking may be in use in the same cloud. However, a given zone must use
|
|
either Basic Networking or Advanced Networking.</para>
|
|
<para>Different types of network traffic can be segmented on the same physical network. Guest
|
|
traffic can also be segmented by account. To isolate traffic, you can use separate VLANs. If you
|
|
are using separate VLANs on a single physical network, make sure the VLAN tags are in separate
|
|
numerical ranges.</para>
