Besides web browser client, DCV offers Windows, Linux and macOS native clients that support additional features such as QUIC UDP transport protocol, multi-channel audio, and printer redirection. Native clients can be download from https://www.amazondcv.com/.
You can restrict DCV access to native clients only by removing web browser client. On Linux instances, remove nice-dcv-web-viewer package. On Windows instances, download nice-dcv-server-x64-Release.msi and run the command msiexec /i nice-dcv-server-x64-Release.msi REMOVE=webClient from administrator command prompt.
DCV supports USB remotization, allowing use of specialized USB devices, such as 3D pointing devices and two-factor authentication USB dongles, on Windows and Linux OSs. To use feature on a supported Linux server OS, run the command sudo dcvusbdriverinstaller and restart EC2 instance. Feature is for installable Windows clients only.
Amazon DCV server automatically generates a self-signed certificate. For Windows and some Linux OSs, the template will attempt to use Posh-ACME (Windows) or Certbot (Linux) to request and install valid Let's Encrypt IPv4 address certificate. This feature is only available if displayPublicIP is Yes and allowWebServerPorts allows HTTP.
IP address certificates are valid for 160 hours, just over six days, and Certbot/Posh-ACME will attempt to renew them before expiry. To ensure proper operation, use assignStaticIPto associate a static IPv4 address. Renewal on Windows is managed through task scheduler; do update the tasks' user credentials if you change administrator password.
DCV also support domain-validated certificates, including AWS Certificate Manager (ACM) exportable public certificates. Refer to DCV, ACM, Certbot and Posh-ACME documentation for more details.
If you have a fleet of Amazon DCV servers, you can use Amazon DCV Connection Gateway to centralize access. Refer to blog Getting started with managing NICE DCV sessions secured behind a NICE DCV Connection Gateway and dcv-samples for more information.
Consider Research and Engineering Studio on AWS (RES) if you need to manage secure cloud-based research and engineering environments, and Amazon WorkSpaces Family if you are looking for a fully managed VDI (virtual desktop infrastructure) service.
Default Windows AMI is now Windows Server 2025 English-Full-Base. You can retrieve SSM paths to other AMIs from Parameter Store console, AWS CloudShell or AWS CLI. Refer to Query for the Latest Windows AMI Using Systems Manager Parameter Store blog for more information.

If you enable AWS Backup (enableBackup), you can restore your EC2 instance from recovery points (backups) in your backup vault. The CloudFormation template creates an IAM role that grants AWS Backup permission to restore your backup. Role name can be located in your CoudFormation stack Resources section as the Physical ID value whose Logical ID value is backupRestoreRole
The CloudFormation templates are designed to provision EC2 instances in public subnet. To use them for EC2 instances in private subnets with internet connectivity, set displayPublicIP value to No.
To use templates in AWS Local Zones, verify available services features and adjust CloudFormation parameters accordingly. You may have to change osVersion, instanceType and volumeType, and set assignStaticIP to No.
To secure your EC2 instance, you may want to
- Set a strong login user password
- Install a valid TLS certificate
- Remove web browser client restricting access to native clients only
- Restrict DCV/SSH/RDP/Webmin access to your IP address only (
ingressIPv4andingressIPv6) - Linux: disable SSH access from public internet (
allowSSHport)- Use EC2 Instance Connect or SSM Session Manager for in-browser terminal access, or
- Start a session using AWS CLI or SSH with Session Manager plugin for the AWS CLI
- Windows: disallow RDP (
allowRDPport) access from public internet.- Use Fleet Manager Remote Desktop for in-browser RDP access.
- Use AWS Backup (
enableBackup) data protection- Enable AWS Backup Vault Lock to prevent backups from accidental or malicious deletion, and for protection from ransomware.
- If your Region does not support AWS Backup, you can setup automatic EBS snapshots using Amazon Data Lifecycle Manager.
- If hosting a website
- Use Amazon CloudFront (
enableCloudFront) with VPC Origin. - Consider CloudFront flat-rate pricing plans that combine CloudFront with multiple AWS services, and features monthly price with no overage charges regardless of whether your website goes viral or faces a DDoS attack
- Additional inbound HTTP security groups with AWS managed prefix list for Amazon CloudFront as source are created. Restrict EC2 HTTP and HTTPS inbound access to CloudFront only by removing public internet inbound (0.0.0.0/0) from security group.
- Use AWS WAF to protect your CloudFront distribution
- Use Amazon CloudFront (
- Enable Amazon Inspector to scan EC2 instance for software vulnerabilities and unintended network exposure.
- Enable Amazon GuardDuty security monitoring service with Runtime Monitoring and Malware Protection for EC2
Amazon CloudWatch agent is installed in the EC2 instance, and enables collection of EC2 system-level metrics and AWS X-Ray traces. The template configures agent to collect memory, disk, and some GPU (*-with-NVIDIA-*) utilization metrics. To collect other metrics, you can configure using EC2 console or manually as follows.
Manually create agent configuration file or use agent configuration file wizard:
-
Linux:
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard
-
Windows PowerShell:
cd "C:\Program Files\Amazon\AmazonCloudWatchAgent".\amazon-cloudwatch-agent-config-wizard.exe
After config.json file is created, start CloudWatch agent:
-
Linux:
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -s -c file:/opt/aws/amazon-cloudwatch-agent/bin/config.json
-
Windows PowerShell:
cd "C:\Program Files\Amazon\AmazonCloudWatchAgent".\amazon-cloudwatch-agent-ctl.ps1 -a fetch-config -m ec2 -c file:config.json
Refer to How do I install and configure the unified CloudWatch agent to push metrics and logs from my EC2 instance to CloudWatch? for details. To collect GPU metrics, refer to How do I send NVIDIA GPU metrics from my EC2 Linux instances to CloudWatch? and Collect NVIDIA GPU metrics
There is no additional charge for using AWS CloudFormation. You pay for AWS resources created using the template the same as if you had created them manually. You only pay for what you use, with no minimum fees and no required upfront commitments.
Where possible, template assigns all created resources with user-defined tags of key names StackName and StackId. You can activate them as cost-allocation tags to track your AWS costs on a detailed level. Refer to AWS Billing User Guide for more information.
To remove created resources,
