Creating connection between Azure and Amazon EC2

On Amazon side:

Create new elastic IP

Select Virtual Private Cloud-Elastic IPs-Allocate new address

Click allocate

I used default VPC if you need to create new VPC,take a look here

Create EC2 instance and assign VPC (default or custom one and subnet)

Allocate Elastic IP to instance-in EC2 select instance-Actions-Associate address

Resource Type-instance-select instance and  Private IP

Azure portal

Create Virtual Network Gateway (details here)

Create Local Network Gateway

IP Address:Amazon Elastic IP (created earlier)

Address Space (Amazon VPC subnet to which EC2 instance is assigned)

Once Local network gateway is created go to Connections-Add

Select Virtual Network gateway,local network gateway and shared key

Copy Virtual network gateway IP

find out Azure VM network

Click on Azure VM-Networking to find out subnet name

write down subnet, it will be needed for Powershell script

On AWS EC2 instance install RRAS and configure IPSec VPN.In this case 137.117.170.80 is Azure Virtual Network Gateway IP,10.0.1.0/24 Azure VM subnet and 123456 Secret Key

# Windows Azure Virtual Network

# This configuration template applies to Microsoft RRAS running on Windows Server 2012 R2.
# It configures an IPSec VPN tunnel connecting your on-premise VPN device with the Azure gateway.

# !!! Please notice that we have the following restrictions in our support for RRAS:
# !!! 1. Only IKEv2 is currently supported
# !!! 2. Only route-based VPN configuration is supported.
# !!! 3. Admin priveleges are required in order to run this script
