Edge to Cloud Hybrid Connectivity with Aviatrix Cloud Network Backbone

This article is about a journey of a customer from on-prem edge location to public cloud. The best part is that this journey is applicable to almost 80% of customers so it is easily adoptable without boiling the ocean or without disrupting anything you already have in place.

Extending Security Domains to AWS – IPSEC

To make it short:we are classifying spokes in security domains and isolate these domains from each other. That can be extended to multi-cloud, on-prem, vpn. (More details)Let’s focus on AWS TGW today…There is also feature called “TGW Orchestration” which allows Aviatrix controller to program TGW and manage its RTB and also utilizing these security domains. It is pretty powerful but has one big limitation – we are able to extend segmentation only to EDGE transit domain. So if you peer this Transit to another Aviatrix transit pair in a different CSP you will not see them. That’s why we are going to build it differently – by defining Connections between Aviatrix Transit and  AWS TGW. With Connection definition we can extend it further and fully utilize potential given with MCNA (Multi-Cloud Network Architecture) by Aviatrix. Sometimes you just might not be the owner of TGW and you just need to do it that way. Desired Topology  When defining connection you need to be aware how Aviatrix Gat

Extending Security Domains to AWS via GRE (connect attachment)

One of the way to provide connectivity from AWS to AVX is via IPSEC tunnels. There are however few limitations in regard to that. Throughput is the biggest concern there. We can of course increase number connections and it serves its purpose well, but lets do it a little bit differently.  We will leverage different type of TGW attachment  (CONNECT). In order to do that we need to have our Aviatrix TrGW deployed in AWS and build underlay for our GRE tunnels. This underlay is actually another attachment type (well known – VPC ATTACHMENT). Important note:‘You can create up to 4 Transit Gateway Connect peers per Connect attachment (up to 20 Gbps in total bandwidth per Connect attachment), as long as the underlying transport (VPC or AWS Direct Connect) attachment supports the required bandwidth” There is also another factor when thinking about such a high bandwidth – Aviatrix TrGW CPU – instance size basically. Why connecting AWS TGW with Aviatrix TrGW that way? Why not using just Aviatrix

Aviatrix Transit Gateway: Error: [AVXERR-MAINTENANCE-004] Upgrade/Restore in progress

We are using the aviatrix terraform resource `"aviatrix_transit_gateway"`  to build a transit gateway but we are getting the following error.  failed to create Aviatrix Transit Gateway: rest API create_transit_gw Post failed: Error: [AVXERR-MAINTENANCE-004] Upgrade/Restore in progress. Please try again after maintenance action is finished. with aviatrix_transit_gateway.avx_build, on vpc.tf line 2, in resource "aviatrix_transit_gateway"   The following is the structure of our resource: resource "aviatrix_transit_gateway" "avx_build" { single_az_ha = true gw_name = "avx_build_gw" vpc_id = vpc.avx_build.id cloud_type = 1 vpc_reg = var.region connected_transit = true gw_size = "t3.medium" account_name = var.cloud_account_name subnet = aws_subnet.avx_build_subnet.cidr_block enable_advertise_transit_cidr = true bgp_manual_spoke_advertise_cidrs = "some-ip-addr-ranges-here" }   Is it due to an aviatrix maintenance or a possible error on our side?

Aviatrix Transit VPC - DXGW

Today, we are using Aviatrix as TGW orchestrator only. We have AWS Direct Connect connections to two TGWs in different regions connecting to AWS Direct Connect Gateway. If we decide to deploy Aviatrix Transit VPC, do we still need AWS TGW? If not, how will I connect my on-prem to the Aviatrix Transit VPC?

Aviatrix Transit VPC - Global or Regional

Hi, Apologies if this basic question has been answered already but could not find any reference Is  the Aviatrix Transit GW a regional service or Global ? Will the Solution work if I have 1 VPC in US-West and another VPC in US-East with the  Aviatrix Transit VPC in any of these regions ? or is it that we need to deploy 2 Transit VPCs - one each of US-West  &  US-East and interconnect both these VPCs for reachability ?

Multicloud Transit Routing and Networking FAQs

Are there any BGP route limitations in Aviatrix? There are no limitations. Does VNet peering have route limits like AWS? You have a limit of 500 VNet Peers. Anytime you need to change a CIDR or add a new subnet you need to break ALL the peerings. Which means it will cause an outage. The same challenges apply in AWS. Using Aviatrix TG, can AWS applications talk to applications in GCP or Azure? Absolutely, and it's very easy to do.             Does Aviatrix GWs still work if the controller is down? Yes. Controller is not in the data path. Does Aviatrix Gateway and controller run on Linux VM's? Yes. But they are launched from the marketplace and automated, you do not have to do anything on a terminal. If the Aviatrix Transit Gateway is provided by Aviatrix, does that work for a customer only hosted across AWS? Aviatrix Transit works across AWS/Azure/GCP/OCI. Will subnets in the Transit Gateway have routes to all other VP

How can I automate VPC network segmentation using AWS Transit Gateway (TGW) and Aviatrix?

Network segmentation is a highly effective strategy to limit the impact of network intrusion. This article delves into ways to simplify network segmentation and how Aviatrix Network Security Domains, along with AWS Transit Gateway (TGW), provide a solution for secure network traffic in multi-VPC environments. Cloud Network Segmentation: why and how? First, let’s look at why network segmentation is vital to network security. In the traditional data center networks, segmentation was primarily done via a DMZ or perimeter which had firewall devices. The issue here was that once a bad actor got into the network, they gained wide reach throughout the “private” network. Segmentation approaches called for partitions of numerous smaller networks, reducing the reachability for intruders, minimizing the damage they could do. This type of segmentation involves developing and enforcing a set of rules to manage the traffic between segments. The best practice was to find a manageable level

How are the VPC route tables updated when connecting VPCs via AWS Transit Gateway (TGW)?

AWS Transit Gateway (TGW) enables customers to connect their VPCs and their on-premises networks to a single gateway. It acts as a hub that controls how traffic is routed among all the connected networks which act like spokes. The AWS Transit Gateway (TGW) was designed to replace the older Transit VPC architecture, which deployed third-party instances that performed transitive routing functions. While both the AWS Transit Gateway (TGW) and the older Transit VPC constructs allow for connectivity, the routing updates and related challenges are entirely different. Let’s take a look at the legacy approach of implementing transit using the Transit VPC architecture:   The connectivity to on-premise relies on Direct Connect or IPsec VPN and terminates in a VGW, which is attached to the Transit VPC. A third-party appliance (Cloud Router) with transitive routing capabilities connects the VGW to all the “spoke VPCs.” In this construct, the on-premise (or Datacenter) environment

How many route table updates will I have to manage for large Transit Gateway deployments?

The AWS Transit Gateway (TGW) was introduced to eliminate complexity involved in peering many VPCs together. In the pre-AWS Transit Gateway (TGW) world, if you had to connect many VPCs, you were required to use a complex mesh of VPC peerings. To be accurate n (n-1)/2, where n is the number of VPCs. AWS Transit Gateway (TGW) was introduced to make peering of VPCs easier. But, it does not make routing easy. When attaching the AWS Transit Gateway (TGW) to a VPC, it does not propagate routes to the VPCs. Similarly, creating propagation across route tables in the AWS Transit Gateway (TGW) does not automatically populate routes into the respective tables. The formula of how many route tables need to be managed, reviewed and updated when using an AWS Transit Gateway (TGW) is equal to: n ( s + r - 1), where n is the number of VPCs attached to the AWS Transit Gateway (TGW), s is the number of subnets in each VPC and r is the number of route tables in the AWS Transit Gateway (TGW).
