Verizon is bringing cloud computing closer to its 5G network edge by teaming with Amazon WebServices (AWS). Verizon will use AWS Wavelength, Amazon’s new cloud platform designed foredge computing, to make it easier for developers to create and deploy low latency applications.

Speaking at the Wells Fargo TMT investor conference, Adam Koeppe, senior vice president oftechnology and planning at Verizon, explained that Verizon is integrating AWS Wavelength atstrategic locations within its 5G network that uses the its 28 MHz mmWave spectrum. Wavelengthwill basically open up Verizon’s network to AWS developers that want to create low-latencyapplications that will run on a 5G distributed network. Examples of these types of low-latencyapplications include smart cars and cities, augmented and virtual reality, Internet of Things andgaming.

Koeppe said that customers are already testing Wavelength technology in Chicago where Verizonhas deployed its 5G network. The two companies said they plan to make the 5G edge computing

AT&T and Microsoft announce earlyresult of their 5G-cloud partnership

Updated 5:47 PM ET, Tue November 26, 2019

By Clare Duffy, CNN Business

New York (CNN Business) — AT&T and Microsoft have announced the next phase of a partnership that's aimed atadvancing development in two of the buzziest areas of tech: 5G and cloud computing.

The companies inked an agreement in July to work together on innovations in 5G and cloud. 5G is next generationnetwork technology that's expected to change the way people live and work. And the cloud is distributed datastorage and computing power that doesn't rely on traditional on-site data centers. AT&T (T) (CNN's parentcompany) also agreed to migrate its data and workflows to the Microsoft Azure cloud, in what was reportedly amore than $2 billion deal for Microsoft (MSFT), according to Reuters.

On Tuesday, Microsoft and AT&T's business unit announced the pilot launch of their so-called "network edgecompute" technology, an early outcome of the partnership. The advancement is expected to help both companies'enterprise customers take advantage of the benefits of 5G, as AT&T works to roll out 5G across the US by mid-2020.

"We've said all year, developers and businesses will be the early 5G adopters, and this puts both at the forefront ofthis revolution," AT&T Business Chief Marketing OWcer Mo Katibeh said in a statement Tuesday.

AT&T will implement the Microsoft technology in some of the major metro areas where it's installed 5G — AT&Tsays it will be available for select customers in Dallas early 2020, with Los Angeles and Atlanta slated forimplementation later in the year.

Microsoft and AT&T are excited about the technology's potential, but Gartner analyst Bill Menezes says it's not yetclear just how useful this technology will be and when it will be usable.

"Right now, it's creating a lot of noise that plays on a lot of current buzzwords in tech," Menezes said. "What itactually produces remains to be seen."

What is network edge compute?"Network edge compute" is a mouthful. Here's what it means:

5G promises to bring super fast download speeds, the ability to connect millions of devices and the ability toprocess massive amounts of data in nearly real time. But if those devices are connected to the cloud, reaping the

Deutsche Telekom Embarkson Edge Computing for IoT

T-Systems, a subsidiary of global operator Deutsche Telekom, unveiled an edge

computing platform that delivers low latency for IoT applications in enterprise

facilities. The EdgAir platform is designed to operate like a private cloud to ensure

security and transmit data in less than 10 milliseconds, according to the IT services

and consulting company.

The platform is based on OpenStack and allows enterprises to run IoT applications as

virtual machines (VM) or in Docker containers as microservices that operate

independent of the underlying infrastructure. The containers are also coordinated via

Kubernetes and EdgAir equipment can be installed as a pole mount, ruggedized rack,

or a standard rack.

“In combination with Time Sensitive Networks and a very good service level

agreement, our managed platform EdgAir can meet requirements such as real-time

control of machines in a production hall,” said Albert Kroisleitner, senior product

manager of edge platform at T-Systems, in a prepared statement.

How do the small ones help …

What help do small ones need …

• Reduce latency to few ms• Save backhaul bandwidth

• Handle multiple applications• Power/energy constraints

This session

Prediction-Based Power Oversubscription in Cloud Platforms• Power is important • Power oversubscription is

limited • Prior work assumes hard

to get info • Reactive, expensive

mechanisms

• Prediction-based approach• Predict VM criticality &

utilization• Protect critical VMs by

intelligent placement • 2x oversubscription

Proactive Energy-Aware Adaptive Video Streaming on Mobile Devices

• ABR widely used video 360 streaming – App adaptation• Prior work, mostly reactive causes

adaptation oscillations• Difficult to predict energy usage• Energy use is cummulative

• Integrated, Pro-active ABR adaptations for video• Reactive vs. Proactive• Function wise power prediction • Practical control algorithm

Video Analytics with Zero-streaming Cameras

• A lot of cameras (surveillance)• Huge amounts cold video

(nothing interesting)• Especially for ad-hoc queries:

retrieve, tag, count• Why stream … even to edge• Cloud processing only needed if

more accuracy is needed

• Zero-streaming• Leverage spatial skew in

landmarks• Cloud provides increasingly

complex / more accurate operators based on policy• Multi-pass, multi-operators• 100x more video in realtime

ASAP: Fast Mobile Application Switch via Adaptive Prepaging

• Everyone uses more than one app • Switching b/w them can be faster

(useful)• Cause – slow demand paging• Requires careful low level design

to avoid overheads

• Predict likely to be accessed pages / pre-page• Ensure reasonable overheads• 20-30% faster switch • Additional 30% CPU & 25% disk

bandwidth usage
