    Article summary

    As an alternative to cloud managed Kubernetes deployments, Glasswall Halo can also be deployed via a single-node configuration into traditional Virtual Machine infrastructure. This is an option for deployment to on-premise environments where utilisation of cloud infrastructure is not possible.

    Single-node deployments comprises of three main components (for version information, please see our Release Notes):

    • Red Hat Enterprise Linux base operating system
    • Rancher Kubernetes Engine Government (RKE2) - a Cloud Native Computing Foundation (CNCF) certified Kubernetes distribution
    • Glasswall Halo Helm charts and container images

    To simplify deployment of the above components, preconfigured VM images are available in OVA and VHD image formats.

    Security Posture

    The following security hardening procedures have been carried out for each of the main components of the VM deployments:

    Security reports from the above procedures are available on request.

    Current Limitations of Single-Node VM Deployments

    When deploying in the single node configuration, scalability is limited to the size of the target VM. The Single-Node deployment will dynamically allocate the correct number of engines based on the avaliable resources of the underlying VM.
