Deployed on AWS
KARL runs VMs, Windows desktops and containers on one Kubernetes platform with its own KVM runtime. Built-in RDP Gateway, directory services, file shares, backup and security help replace separate hypervisor, VDI and infrastructure tools. Deploy on AWS with AMI and CloudFormation.
Overview
KARL is a Kubernetes Virtualization and DaaS platform designed to run and govern virtual machines, Windows desktops and container-based workloads from a single operational layer.
Unlike generic infrastructure governance tools, KARL combines its own KVM-based runtime with built-in services for desktop delivery, secure access, directory integration, software-defined networking, storage, data protection, observability and runtime security. This allows organizations to consolidate functions that are often split across separate hypervisor, VDI, access, backup and security products.
On AWS, KARL can be deployed through AMI and CloudFormation-based deployment models, using supported EC2 instance families and configurations that provide the virtualization capabilities required by the KARL runtime. Once deployed, infrastructure teams can provision Linux and Windows VMs, pooled Windows desktops, application environments and governed workload pools with centralized control over compute, networking, storage, access and security.
KARL includes a secure RDP Gateway for desktop and VM access, directory services based on Samba Active Directory concepts, group policy integration, software-defined networking, workload placement visibility, connectivity diagnostics, file services, backup workflows and Warden-based security capabilities for compromised desktop recovery.
The platform is designed for enterprises, service providers and system integrators that need to modernize legacy virtualization and VDI stacks, support VMware or Citrix transition projects, deliver secure workspaces, operate governed customer environments and reduce the operational fragmentation caused by managing hypervisors, VDI brokers, access gateways, storage, backup and security tools separately.
KARL is especially relevant where customers need one platform for virtual machines, Windows desktops and containers, with centralized governance, AWS deployment support and operational visibility across the workload lifecycle.
Highlights
- Run Windows and Linux VMs plus pooled Windows desktops on one Kubernetes platform using KARL's own KVM runtime, with secure RDP Gateway, 2FA access, directory services and GPO integration.
- Replace fragmented hypervisor, VDI, access and infrastructure tools with a unified platform for compute, networking, storage, secure access, observability, file services and workload governance.
- Protect desktop and workload environments with SMB/NFS file services, per-file audit, ransomware lockout, scheduled backup to Amazon S3 and Warden-assisted recovery for compromised desktops.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
