Create a default network
When using TWAI Virtual Compute Service (VCS) for the first time, you must create a default network in Virtual Network service before using VCS. If you need other network segments, check this document to create a new one.
Set environment variables
For information on setting environmet variables, please refer to HowTo: Set environment variables.
SSH Linux with password
In addition to using the key pair as a credential for connecting to Linux instances using SSH, this document will show you how to use the account password to connect to the VCS Linux instance using SSH. This method prevents situations where the lost or the corruption of the key pair that makes connecting to the instance impossible, and is suitable for multiple users sharing instances.
Install NVIDIA GPU driver
TWAI offers vgv-series instances equipped with NVIDIA® Tesla V100 GPUs. When you finish creating a VCS GPU instance, please follow steps below to install NVIDIA GPU driver to enable GPU resources to accelerate computing.
Initialize a Linux data disk
To increase the storage space for the existing VCS instances, create and attach data disks of Virtual Disk Service to the target VCS instance. Then, for both Windows and Linux operating systems, the initialization of the disk is required so that the VCS instance can detect your mounted storage space and store the data.
Initialize a Windows data disk
To increase the storage space for the existing VCS instances, create and attach data disks of Virtual Disk Service to the target VCS instance. Then, for both Windows and Linux operating systems, the initialization of the disk is required so that the VCS instance can detect your mounted storage space and store the data.
Best practices to create a VCS instance image
You can create TWAI VCS instance image in a variety of situations, but before creating, please perform the following tasks to ensure that the image will be effectively obtained:
Resize a VCS instance with images
This tutorial will show you how to resize your VCS instance using the Image function to quickly transfer instance data and configuration to a new instance with different size.
Resize a VCS instance
This tutorial will explain how to change the VCS instance type using the TWAI portal, allowing users to resize your instance without having to recreate one.
Convert SSL certificate format
The SSL certificate of the TWAI Load Balancing (HTTPs with SSL) service adopts Base64 encoding format. This document will help users to combine SSL certificate files into PKCS #12 and convert to Base64 encoding format.
Replace a data disk
If you need to change the type of data disk (e.g., replace SSD with HDD), or change the capacity of data disks (e.g., replace small capacity with larger capacity), please refer to this document to synchronize the data from the original disk to the new data disk, and then delete the original one.
Client-to-Site VPN connection
In this tutorial, we will teach you how to install OpenVPN on TWAI VCS instances to establish a secure connection from the local computer to the jump server, and then from the jump server to other instances in the same virtual network.
Create site-to-site VPN via Advanced Virtual Firewall

Configure an NTP server
The following instructions describe how to set up a specific time zone for a VCS instance so that it can be automatically calibrated: CentOS instances use native commands to set up the time zone, while Ubuntu instances use an external time server to set up the time zone.
Add instances to the protected scope via the jump server
Prerequisites
Add a Virtual Network Interface (VNI) to your VCS instance
If your instance is running on Ubuntu 18.04 or newer versions, and was created before December 15, 2023, this feature may not be fully supported. If you encounter issues such as VNI not being automatically enabled, connection failures, or other problems, please manually configure settings within the Guest OS. If the issue persists, please contact TWAI technical support: service@twcloud.ai.
Deploy enterprise-level Microsoft SQL services on public clouds

Install GPU drivers via initial scripts
This document explains how to install GPU drivers through initial scripts when creating a VCS instance using the TWAI Portal.
