<title>Adding Tiers</title>
|
|
<para>Tiers are distinct locations within a VPC that act as isolated networks, which do not have
|
|
access to other tiers by default. Tiers are set up on different VLANs that can communicate with
|
|
each other by using a virtual router. Tiers provide inexpensive, low latency network
|
|
connectivity to other tiers within the VPC.</para>
