-Terraform for VyOS
-==================
+Deploying VyOS in the AWS cloud
+===============================
 
-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.
-More detailed about what is Terraform you can write using the link_.

+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

+
+Deploying VyOS in the vSphere infrastructure
+============================================
+
+With the help of Terraform, you can quickly deploy VyOS-based infrastructure in the vSphere.
+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 vSphere cloud and make provisioning using Ansible.
+
+Preparation steps for deploying VyOS on vSphere 
+-----------------------------------------------
+
+How to create a single instance and install your configuration using Terraform+Ansible+vSphere 
+Step by step:
+
+
+vSphere
+
+
+  1 Collect all data in to file "terraform.tfvars" and create resources for example "terraform"
+
+
+Terraform
+
+
+  1 Create an UNIX or Windows instance
+
+  2 Download and install Terraform
+
+  3 Create the folder for example /root/vsphereterraform
+
+.. code-block:: none
+
+ mkdir /root/vsphereterraform
+ 
+
+  4 Copy all files into your Terraform project "/root/vsphereterraform" (vyos.tf, var.tf, terraform.tfvars,version.tf), more detailed see `Structure of files Terrafom for vSphere`_
+
+  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/vsphereterraform/
+
+  4 Copy all files into your Ansible project "/root/vsphereterraform/" (ansible.cfg, instance.yml,"all"), more detailed see `Structure of files Ansible for vSphere`_
+
+
+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 vSphere 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_.
