Introduction

The evolution and rapid progression of new technologies like augmented reality, autonomous vehicles, drones, and smart cities are inevitable.  

...

There are many open source projects that provide component capabilities required for edge computing.  However, there is no holistic solution to address the need for fully integrated edge infrastructure. 

Akraino Edge Stack, a Linux Foundation project initiated by AT&T and Intel, intends to develop a fully integrated edge infrastructure solution, and the project is completely focused towards Edge Computing.  This open source software stack provides critical infrastructure to enable high performance, reduce latency, improve availability, lower operational overhead, provide scalability, address security needs, and improve fault management.  The Akraino community will address multiple edge use cases and industry, not just Telco Industry. Akraino community intends to develop solution and support of carrier, provider, and the IoT networks.

Intel upstreamed Wind River Titanium Cloud portfolio of technologies to open source in support of additional blueprints in Akraino. 

The Akraino Edge Stack Community, while embracing several existing open source projects, will continue the focus on the following Community Goal:

To ensure timely information arrives for data-driven decisions for manufacturing and shipping businesses, edge computing is also beneficial. Receiving and processing this data at the edge allows more timely decision making leading to better business outcomes.

Network Edge - Optimal Zone for Edge Placement

The processing power demands of customer devices, namely AR/VR, Drones, and Autonomous Vehicles are ever increasing and require very low latency, typically measured in milliseconds.  The place where processing takes place plays a major role with respect to quality of user experience and cost of ownership.  Centralized cloud decreases the TCO, but fails to address the low latency requirement.  Placement at customer premises is nearly impossible with respect to cost and infrastructure.  Considering the cost, low latency, and high processing power requirements, the best available option is to utilize the existing infrastructure like Telco’s tower, central offices, and other Telco real estates.  These will be the optimal zones for the edge placement.

The Akraino Edge Stack is a collection of multiple blueprints. Blueprints are the declarative configuration of entire stack i.e., Cloud platform, API, and Applications. Intend  Intent of Akraino Edge Stack is to support VM, container and bare metal workloads.  Akraino is a complimentary OpenSource project and it is intended to use upstream community work in addition to the software development within the Akraino community. 

A typical service provider will have thousands of Edge sites. These Edge sites could be deployed at Cell tower, Central offices, and other service providers real estate such as wire centers. End-to-End Edge automation and Zero-Touch provisioning are required to minimize OPEX and meet the requirements for provisioning agility. 

The Akraino Edge Stack is intended to support any type of access methodologies such as Wireless (4G/LTE, 5G), Wireline, Wi-Fi, etc., 

In order to be resilient, Akraino Edge Stack deployment intent to follow the hierarchy of deployments such as collection of central sites that deploy a collection of regional sites. The regional sites that facilitate the deployment of Edge Sites.   For example, the figure below shows the central site C1 and C2 allows the management of regional sites R1, R2, R3, and R4. And regional sites allows the management of Edge Sites which are remote and closer to the users.
