Overall Architecture

  • Fully automated deployment on different platforms: AWS, libvirtGCP, baremetal and virtualBaremetal (KVM)
  • Deploy kubernetes cluster properly configured and tuned for NFV/MEC workloads
  • Enablement of real time workloads
  • Possibility of deploying apps on virtual machines and containers in parallel

The blueprint is based on site/profile/base pattern:

  • base - it will contain a set of Kubernetes manifests that define the common settings of the Kubernetes cluster to be deployed, and the common workloads to be applied on top of it
  • profile - specialization of the cluster depending on profiles (libvirt, AWS and baremetal). It will contain specific configs for each platform, and specific workloads to be applied on top of it
  • site - individual definition of a site, based on a chosen profile. It will contain specific configurations for the site (name, domain, network/servers settings, etc...)

Platform Architecture

This blueprint is expected to run on multiple environments (libvirt, AWS and baremetal).

The blueprint validation lab uses 7 SuperMicro SuperServer 1028R-WTR (Black) with the following specs:
