Overview
The Provider Access Edge blueprint is part of Akraino's Kubernetes-Native Infrastructure family of blueprints. As such, it leverages the best-practices and tools from the Kubernetes community to declaratively manage edge computing stacks at scale and with a consistent, uniform user experience from the infrastructure up to the services and from developer environments to production environments on bare metal or on public cloud.
This blueprint targets small footprint deployments able to host NFV (in particular vRAN) and MEC (e.g. AR/VR, machine learning, etc.) workloads. Its key features are:
- Lightweight, self-managing clusters based on CoreOS and Kubernetes (OKD distro).
- Support for VMs (via KubeVirt) and containers on a common infrastructure.
- Application lifecycle management using the Operator Framework.
- Support for multiple networks using Multus.
- Support for real-time workloads using CentOS-rt*.
