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 ?

Has anyone had the issue of losing the routes between their HA Transit Egress gateways and spokes? We encountered this issue and all it took to rectify the issue was un-attaching then reattaching the spokes but don't seem to have a reason for why they lost the routes in the first place.

Is there a specification for the Aviatrix physical appliance. 

Is this something I should be worried about? Am I doing something wrong in the Lab (1) or has terraform undergone some changes since the course was written? Plan goes ahead anyway, these are just warnings. Is there a way I can fix them?

Hello,   Maybe someone can help me as I have no clue were the problem can be. I have deployed successfully via terraform successfully a Aviatrix Controller and a Co-Pilot, after that I have set up via terraform again a service principal that can deploy configuration ins inside the controller. Now my task is to deploy a VPC and a transit gateway. I have use this script https://github.com/terraform-aviatrix-modules/terraform-aviatrix-mc-transit   How the strange part is that terraform is creating the VPC successfully but for the gateway is failing with the below error.   But in reality the gateway is deployed successfully   Maybe someone has encounter the same problem using this terraform script?   Best Regards Gilbert

Hi, I am working on Aviatrix MCNA and due to cyber requirements cannot run gateways in VPCs with Public IPs. Is there a way to run gateways with a private network subnet? Gateways in Hub can be on public subnets.

is my understanding correct that most challenge in multi cloud lies in networking, access, making sure clouds can send data, communicate to each other?   aviatrix is resolving this complexity?

aviatrix platform is working compatible with alibaba or not? alibaba is pretty big cloud too. 

Hi, I'm looking to ssh into aviatrix gateways and controller launched as part of the labs/sandbox starter. I don't see a ec2 keys associated with these instances. Is there a way to specify ec2 ssh key when launching the controller/gateways during launch? I don't see the option in the UI. I suspect it's forbidden/disallowed for obvious reasons. But, just trying my luck.  Thanks! 

In the scenario above, does customer need to have the Aviatrix physical appliance installed at the on-premises site?   Thanks JF

Hi there, In the Feature Overview Part 2 of Aviatrix Certified Engineer - Multi-Cloud Network Associate Course, the instructor introduced centralized stateful firewall and said "It's best for single GW use cases supported by single GW HA". Can I ask the reason why? Thanks. JF

Hi there, Can I please have more design information of the SDWAN integration with Aviatrix like the diagram being shown in the course? Thanks JF

Hi guys, In the Azure Networking 101 course/video, the instructor said doing Azure Transit via ExpressRoute Edge Routers can avoid VNet Peering data charge. I don't quite get it as there is data charge still on those two VNet Peering between Spoke VNets and Hub VNet that ExpressRoute terminates, isn't there? Or he actually meant avoiding the data charge of VNet Peering between Spoke VNets? But what is the actual difference from commercial prospective? Traversing two VNet Peering through Hub VNet V.S. traversing one direct VNet Peering between two Spoke VNets. Thanks   JF

Hi there, Does anyone knows where I can find the Aviatrix API reference (Swagger) documentation? I remember seeing that in the past, and for some reason I can longer find it. Thank you

Can I create/delete AWS instance from aviatrix GUI?

Is it supported to deploy aviatrix controller across different clouds?

If a user decides to decommission Aviatrix completely, will the user's multi-cloud environment continue to function like before? Will any gateways and other components created by Aviatrix that are native to a particular cloud remain in place? For example, you may have configured routes or security groups or even launched instances through the Aviatrix controller. Will they remain functional?

Hi everyone, I have an Aviatrix Controller deployed and would like to secure browser access with an SSL certificate. Let's Encrypt seems like an easy and cost effective method, however in order to use it I need SSH access to the Controller, which is disabled. If there's anyone that has successfully implemented this I'd love to hear the details! Thanks,   Mark

I was trying to spin up an Aviatrix Cloud Controller at AWS using Sandbox Starter Tool, but keep getting these errors: > The controller will be launched in us-east-1. Initializing modules... Initializing the backend... Initializing provider plugins... - Checking for available provider plugins... --> Controller launch failed, aborting. Registry service unreachable. This may indicate a network issue, or an issue with the requested Terraform Registry. Registry service unreachable. This may indicate a network issue, or an issue with the requested Terraform Registry. registry service is unreachable > If anyone has faced the same issue before, kindly help me to find a solution. I ran starter Tool as docker container in my laptop and accessing to Hashicorp registry is fine from my laptop, not sure why it complains Terraform registry service is unreachable. ===Debug Message== --> Controller SSH key already exists, skipping. --> OK. --> Now going to launch the controlle

Hello everyone, I need your support for a question regarding Azure Vnet which I didn't get from the blog. Can a VNET span across multiple regions?

Aviatrix support many ways to do this. Build an SD-WAN POP in a VPC/VNET with SD-WAN virtual appliances, and then northbound you build standards-based IPsec/GRE tunnels + BGP over Public or Private peerings to the Aviatrix transit. The aviatrix transits can be instantiated in any region or any cloud, as many as you want, wherever you want. So you can build a nice architecture where your SD-WAN remote sites terminate at the closest POP to where their cloud apps live. You can put the SD-WAN appliances in the same VPC /VNET as aviatrix transit and do IPsec/GRE + BGP OR you can do native BGP with no tunneling for higher throughput. You can connect Aviatrix transits via IPsec/GRE + BGP over the internet/MPLS/direct-connect/express route to an on-premise physical SD-WAN appliance. More details can be found on your Aviatrix Youtube Channel where Dana (SD-WAN Expert) has a lot of videos explaining the design and deploy. You can also send an email to info@aviatrix.com

Hi I noticed the section on VPN gateways has stated the following:   Note a /24 VPN CIDR block supports about 64 simultaneous VPN clients. This is because for each connected VPN client, VPN gateways reserves 3 virtual addresses. For larger number of clients per VPN gateway, consider making the VPN CIDR block to a /22 or /20 network.   Is 'reservation of 3 virtual addresses' by VPN gateways is due to the Load balancing that can be implemented across the gateways?   Jeff

Hi  After making the unfortunate error of of terminating my 'Sandbox Starter' AMIs via the AWS console, instead of using the Sandbox 'Destroy' menu option, I have just spent some considerable time uninstalling my Desktop Docker, deleting Aviatrix policies, deleting/generating keys, etc in my efforts to get the  Sandbox Terraform script to successfully complete it's setup of the Sandbox again. It has proven to be a painful learning and time consuming process. So - I have some questions: 1 -  In the the event that I mistakenly terminated a SandBox AMI via the AWS console, is there a script/command available that can be used to rebuild that particular AMI again? 2 - In the event that no such 'rebuild' script/command exists, will using the 'Destroy' option remove all remaining elements of the existing Sandbox, so that a new Sandbox can be successfully installed by running 'Sandbox Starter' again? - or is it not that simple? 3 - Does creation of a new Sandbox

I'm considering creating the Azure VNET part of the Sandbox to build on my knowledge of Aviatrix. However - I cannot find any information on the type of minimum build/specification (eg memory, processor, storage, build type) that I need to select to successfully create the transit & spoke gateways.  If the this automatically done by the script Sandbox script, I would still like to know what would be selected as I want to know what is the cost of running the Azure instances before I consider going ahead with creating the VNET. Can someone please advice - thanks.
