High-level Architecture

The figure below shows the collection of technologies that enable enables the Akraino Edge Stack Network Cloud (NC) Blueprint. This picture also highlights the items in the initial seed code of this blueprint. 

. At the bottom of the stack different hardware and software components can be selected based on deployment needs at a particular edge site. The Akraino Portal at the Regional site provides a menu-driven user interface to select a blueprint for the edge site. Once a blueprint is selected, end-to-end edge automation is used to build the site. Building a site entails making sure network connectivity exists for all compute and control nodes in the rack and between racks including connectivity to network racks.

Akranio utilizes Platform for Intelligent Network Control This blueprint plans to utilize Platform for Intelligent Network Control (PINC) to provide network automation which includes bootstrapping the network devices in the CLOS fabric and providing needed configuration for fabric connectivity (PINC is not part of initial seed). Once network readiness is achieved, Akraino blueprint automation can start the build process for the given site with the chosen blueprint using the portal. Akraino leverages upstream open source AirShip source project AirShip to provide deployment automation for the under cloud as well as the deployment of OpenStack components. Both PINC and AirShip leverage Network Augmentation Resource Automation (NARAD) for inventory management. 

The Akraino portal provides the ability to trigger the end-to-end testing framework leveraging OPNFV (Yardstick), OpenStack Tempest and Shaker, Heptico Sonobuoy allows testing at the various layers – infrastructure, under cloud and other layers enabling the deployment of resilient Akraino Edge Cloud sites. Akraino Edge Stack will provide the capability to deploy Open Network Automation Platform (ONAP) at select sites.
