Azure does not supports Availability Zones in all its regions.

There are two types of regions in Azure

1. Recommended Region : A region that provides the broadest range of service capabilities and is

designed to support Availability Zones now, or in the future. These are designated in the Azure portal

as Recommended.

2. Alternate (other) Region: A region that extends Azure's footprint within a data residency boundary

where a recommended region also exists. Alternate regions help to optimize latency and provide a

second region for disaster recovery needs. They are not designed to support Availability Zones

(although Azure conducts regular assessment of these regions to determine if they should become

recommended regions). These are designated in the Azure portal as Other.

Thank you for your visit.

Intra-Region Transitive Options:

VNET Peering - the recommended approach for spoke to spoke communication is VNET peering as

this

leverages the MSFT backbone directly and always takes the preferred path. This option provides the

lowest latency possible and has no bandwidth restrictions as opposed to the options previously

discussed. The disadvantage of this model is this connectivity is a 1 to 1 mapping. Each spoke much

be

peered directly with another spoke in order to facilitate communication which at scale becomes a

web of

interconnected fully meshed VNETS. As such, customers often have challenges in managing the scale

of

VNET peers.

Aviatrix Controller provides a VPC Tracker tool. VPC Tracker is a tool that collects and helps you

manage

your network CIDR ranges at a central place, eliminating the need to keep an Excel sheet on all your

VPC network addresses allocations.By using VPC Tracker tool one can create a VPC.

AWS Direct Connect is a private link into AWS regions that provides bandwidth. The service

is not natively encrypted when initially deployed.

Express Route does not provide network traffic encryption for its circuits!

Google InterConnect NOT encrypted by default.

:

You can peer two transit gateways and route traffic between them, which includes IPv4 and IPv6

traffic. To do this, create a peering attachment on your transit gateway, and specify a transit gateway

in another AWS Region. The peer transit gateway can be in your account or a different AWS account.
