+Deploying VyOS in the AWS cloud
+===============================
+
+With the help of Terraform, you can quickly deploy VyOS-based infrastructure in the AWS cloud. If necessary, the infrastructure can be removed using terraform.
+Also we will make provisioning using Ansible.
+
+

+
+In this case, we'll create the necessary files for Terraform and Ansible next using Terraform we'll create a single instance on the AWS cloud and make provisioning using Ansible.
+
+
+Preparation steps for deploying VyOS on AWS 
+-------------------------------------------
+
+How to create a single instance and install your configuration using Terraform+Ansible+AWS 
+Step by step:
+
+AWS
+
+
+  1 Create an account with AWS and get your "access_key", "secret key"
+
+  2 Create a key pair_ and download your .pem key
+
+.. image:: /_static/images/keypairs.png
+   :width: 50%
+   :align: center
+   :alt: Network Topology Diagram
+
+  3 Create a security group_ for the new VyOS instance and open all traffic

+
+Terraform
+
+
+  1 Create an UNIX or Windows instance
+
+  2 Download and install Terraform
+
+  3 Create the folder for example /root/awsterraform
+
+.. code-block:: none
+
+ mkdir /root/awsterraform
+
+  4 Copy all files into your Terraform project "/root/awsterraform" (vyos.tf, var.tf, terraform.tfvars,version.tf), more detailed see `Structure of files Terrafom for AWS`_
+
+  5 Type the commands :
+
+.. code-block:: none
+
+   cd /<your folder> 
+   terraform init
+
+
+Ansible
+
+
+  1 Create an UNIX instance whenever you want (local, cloud, and so on)
+
+  2 Download and install Ansible
+
+  3 Create the folder for example /root/aws/
+
+  4 Copy all files into your Ansible project "/root/aws/" (ansible.cfg, instance.yml, mykey.pem and "all"), more detailed see `Structure of files Ansible for AWS`_
+
+mykey.pem you have to get using step 1.2
+
+
+Start 
+
+
+Type the commands on your Terrafom instance:
+   
+.. code-block:: none
+
+   cd /<your folder>
+   terraform plan  
+   terraform apply  
+   yes
+
+

+After executing all the commands you will have your VyOS instance on the AWS cloud with your configuration, it's a very convenient desition.
+If you need to delete the instance please type the command:
+
+.. code-block:: none
+
+   terraform destroy
+
+
+Troubleshooting
+---------------
+
+  1 Ansible doesn't connect via SSH to your AWS instance: you have to check that your SSH key has copied into the path /root/aws/.
+Also, increase the time in the file instance.yml from 300 sec to 500 sec or more. (It depends on your location).
+Make sure that you have opened access to the instance in the security group.
+
+  2 Terraform doesn't connect via SSH to your Ansible instance: you have to check the correct login and password in the part of the file VyOS. tf
+
+.. code-block:: none
+
+  connection {
+   type     = "ssh"  
+   user     = "root"              # open root access using login and password on your Ansible
+   password = var.password        # check password in the file terraform.tfvars isn't empty
+       host = var.host            # check the correct IP address of your Ansible host
+  }
+
+
+Make sure that Ansible is pinging from Terrafom.

+Deploying VyOS in the Azure cloud
+=================================
+
+With the help of Terraform, you can quickly deploy VyOS-based infrastructure in the Azure cloud. If necessary, the infrastructure can be removed using terraform.
+Also we will make provisioning using Ansible.
+
+In this case, we'll create the necessary files for Terraform and Ansible next using Terraform we'll create a single instance on the Azure cloud and make provisioning using Ansible.
+
+Preparation steps for deploying VyOS on Azure 
+---------------------------------------------
+
+How to create a single instance and install your configuration using Terraform+Ansible+Azure 
+Step by step:
+
+Azure
+
+  1 Create an account with Azure
+
+Terraform
+
+
+  1 Create an UNIX or Windows instance
+
+  2 Download and install Terraform
+
+  3 Create the folder for example /root/azvyos/
+
+.. code-block:: none
+
+ mkdir /root/azvyos
+
+  4 Copy all files into your Terraform project "/root/azvyos" (vyos.tf, var.tf, terraform.tfvars), more detailed see `Structure of files Terrafom for Azure`_
+
+  5 Login with Azure  using the command 
+
+.. code-block:: none
+
+   az login
+
+2.6 Type the commands :
+
+.. code-block:: none
+
+   cd /<your folder> 
+   terraform init
+
+Ansible
+
+
+  1 Create an UNIX instance whenever you want (local, cloud, and so on)
+
+  2 Download and install Ansible
+
+  3 Create the folder for example /root/az/
+
+  4 Copy all files into your Ansible project "/root/az/" (ansible.cfg, instance.yml,"all"), more detailed see `Structure of files Ansible for Azure`_
+
+
+Start 
+
+
+Type the commands on your Terrafom instance:
+   
+.. code-block:: none
+
+   cd /<your folder>
+   terraform plan  
+   terraform apply  
+   yes
+
+After executing all the commands you will have your VyOS instance on the Azure cloud with your configuration, it's a very convenient desition.
+If you need to delete the instance please type the command:
+
+.. code-block:: none
+
+   terraform destroy

+Terraform for VyOS
+==================
+
+VyOS supports development infrastructure via Terraform and provisioning via Ansible.
+Terraform allows you to automate the process of deploying instances on many cloud and virtual platforms. 
+In this article, we will look at using terraforms to deploy VyOS on platforms - AWS, Azure, and vSphere.
+For more details about Terraform please have a look here link_.
