Multi Cloud: Connecting Azure to AWS and GCP

Overview

Companies are relying more and more on multiple cloud (multi cloud) providers. However, setting up the connectivity between those providers is difficult. And, maintaining and monitoring the tunnels is time-consuming and cumbersome to troubleshoot.

Aviatrix simplifies this by providing simple, point-and-click tunnel creation between cloud providers. Additionally, Aviatrix gives you a single, centralized location from which to troubleshoot and monitor your connections.

Getting Started

The Aviatrix Controller automates, monitors, and reacts to events in each cloud environment on your behalf. In order to do this, we’ll need to configure a few things in each cloud to support this.

We’ll walk through these steps in the following sections. Once complete, you can connect to one or both cloud providers.

Start by logging into the Azure Portal.

Step 1. Install Aviatrix Controller from the Azure Marketplace

The first step is to install the Aviatrix Controller from the Azure Marketplace. Select the Aviatrix Cloud Gateway to AWS and GCP from the Marketplace. Configure the new VM to meet your preferences and requirements. Be sure to allow inbound connections on port 443. Once ready, launch the new VM and continue to the next step.

Step 2. Prepare your Azure Account

While the VM is being deployed in the selected region, configure the following items:

Register Aviatrix with Active Directory

1. Go to the Azure Active Directory (available from the left navigation panel or More Services)

2. Click on Properties (available under Manage on the left inner navigation bar)

   Important

   Copy and save the Directory ID for later use. It will be referred to again as the Application Endpoint.

3. Click on App registrations (available under Manage on the left inner navigation bar)

4. Click on the + New application registration along the top

   

5. Populate the fields as follows:

Field	Value
Name	Aviatrix Controller
Application type	Web app / API
Sign-on URL	http://aviatrix

6. Click the Create button at the bottom of the page.

Add a Key

1. Find and select the application you just registered in the list displayed

   

   Important

   Copy and save the Application ID for later. It will be referred to again later in this document as Application Client ID

2. Click on the Keys in the Settings pane on the right

   

3. Enter a new row:

Field	Value
Key description	Aviatrix
Expires	Never expires

4. Click Save

   

5. Copy the displayed key value and save it for later

   

Important

Save this value. It will be referred to again later in this document as Application Client Secret

6. Close the Keys window using the X in the upper right corner.

Add Required Permissions

1. Select the Aviatrix Controller application registration again (you may already be on it)

2. Click on the Required permissions just above Keys

   

3. Click + Add button

4. Click Select an API (on the right)

5. Find and select Windows Azure Service Management API

   

6. Click Select

7. In the Enable Access panel, click on Access Azure Service Management as organization users (preview) (checkbox next to it will become checked)

   

8. Click Select

9. Click Done

10. Close the Required Permissions panel by clicking on the X in the upper right corner.

Grant Permissions to Aviatrix Controller

1. Go to the Subscriptions service (available from the left navigation panel or from More Services)
2. Click on the subscription where Aviatrix Controller is installed

Important

Copy and save the Subscription ID for later

3. Click on Access Control (IAM)

   

4. Click + Add

5. Populate the fields as follows:

Field	Value
Role	Contributor
Assign access to	Azure AD user, group, or application
Select	Aviatrix Controller

6. Click Save
7. Close the Access control (IAM) panel by clicking on the X in the upper right corner

Step 3. Configure Aviatrix

Your Aviatrix Controller should be up and running by now. Go back to the Microsoft Azure portal and find the newly created instance. Open it and copy the Public IP address.

Open a browser and navigate to https://<public ip address>/ .

Tip

You may receive a warning about the certificate not matching. You can safely ignore this and continue to the page.

When you arrive at the login prompt, login with the Username admin. The password is the private IP address of the Azure instance.

Tip

The Private IP address can be found on the instance page by clicking on the Networking navigation link.

After logging in, you will be prompted to provide your email address. This is used for alert notifications as well as for password recovery. Enter your email address and click OK.

Set the admin password to something you will remember and click Save.

If you require a proxy for this instance to get to the internet, enter that now. Otherwise, click Skip.

Finally, the software will be upgraded. Click the Run button and the latest version of the Controller will be downloaded and installed. This will take a few minutes. Once complete, the login prompt will appear.

Login with the username admin and the new password.

Azure

After logging in, click on the Azure ARM button to connect Aviatrix to your Azure account.

Create Account

Fill out the fields as follows:

Field	Expected Value
Account Name	The login/username for users who will have admin access to Azure resources. For example, AzureOpsTeam.
