Internet of Things (IoT) and Unpredictable Cloud Traffic

Everything from jet engines to refrigerators is joining the Internet of Things, pushing networks to the brink

Unpredictable Cloud Traffic Can Cast a Shadow on a Metro Network

User obsession with digital information shows no signs of abating. As users create, share, and consume content, network traffic volume goes up, growing an average of 30 to 50 percent annually.[1] The increased adoption of cloud technology has made round-the-clock access to content easy.

However, connecting users to content is not just about volume. Bandwidth is driven by applications, which have changed how, when, and where bandwidth is created, used, generated, and originated, making it far less predictable and much harder to manage. The following eight examples show how unpredictable traffic impacts the metro network.

1. Popular video content release
Netflix is the biggest single driver of traffic on the Internet, accounting for 34.2 percent of all downstream usage during primetime hours. The company's new business model of appealing to binge viewers by releasing entire seasons of programs at the same time creates tremendous traffic spikes. Sixteen percent of Netflix subscribers streamed at least one episode on the day Season 2 of House of Cards was released.[2]

2. Mobile handset apps
With an installed base of more than 600 million devices, network operators need to be prepared for Apple's iOS upgrades or suffer from the deluge. Over 50 percent of Apple device users upgraded their device to iOS 7 within two to three days of its release, with 30 percent upgrading within the first day. One study showed that 22 percent of capable devices upgraded to iOS 7 within 10 hours of release.[3] At nearly 1GB per install, each upgrade sucked up bandwidth quickly. Upgrades are predictable, but the traffic from users learning about new features, posting opinions in online forums, or uploading HD how-to videos can increase traffic for days or weeks.

3. 24-hour news cycle
While TV is still the primary news source for consumers, a growing number - currently 28 percent of those under 50 in the U.S. - turn to the Internet for breaking news.[4] Global news coverage of events such as political upheavals, sporting events, or natural disasters is viewed online instantly by billions. To serve the 24-hour news cycle, data is pulled off servers around the world and around the corner, creating geographic unpredictability.

4. Viral videos
Who could have predicted that a Korean singer would rack up two billion YouTube views? This milestone set by "Gangnam Style" is not the only time a viral video has jammed up networks. Ylvis' "The Fox (What Does the Fox Say?)," Jean Claude Van Damme's "Epic Split," or even kitten antics demonstrate that viewers' interests and demand windows are unpredictable. HD is the preferred format for viral reposting, forwarding, and copy-catting. Viewing statistics for highly social videos differ from those for non-viral videos; viral videos tend to peak more sharply and drop off more rapidly.[5]

5. The shift from standard-definition to HD television
HD needs more bandwidth to stream content. YouTube now allows videos to be posted in HD; every minute, 48 hours' worth of video is uploaded to the service.[6] HD will soon be replaced by 4K, which has four times the pixels of today's 1080-pixel HD, creating even more exponential bandwidth growth (Netflix recommends a 25 Mb/s connection for that service).

6. End-user devices
245.4 million tablets will ship worldwide in 2014, along with 1.4 billion smartphones.[7] Due to their limited storage capacity, these devices require network connectivity to deliver full enjoyment to their users by pulling content, video, and games out of data centers. The more powerful these devices become, the more bandwidth they use. Studies have shown that traffic originating from tablets and mobile phones is growing annually by 104 and 79 percent, respectively.[8]

7. Internet of Things
Everything from jet engines to refrigerators is joining the Internet of Things, pushing networks to the brink. In a new Boeing 747, almost every part of the plane is connected to the Internet, recording and, in some cases, sending continuous streams of data about its status. General Electric Co. has said that in a single flight, one of its jet engines generates half a terabyte of data.

8. End-user mobility
Devices are highly portable and change traffic patterns throughout the day. To manage the traffic, service provider networks are becoming larger and more complex. Traditionally, service providers built out networks by adding more and bigger routers; because this traffic is unpredictable, networks are often overprovisioned to handle unforeseen spikes. With this approach, networks are not getting smarter as they grow. Instead, they are becoming more complex and power- and space-hungry, causing data centers and central offices to run out of both physical space and electrical capacity. In many facilities, new equipment cannot be added unless something is removed first - there is just nowhere to put it or plug it in.

Enterprise architects are increasingly adopting multi-cloud strategies as they seek to utilize existing data center assets, leverage the advantages of cloud computing and avoid cloud vendor lock-in. This requires a globally aware traffic management strategy that can monitor infrastructure health across data centers and end-user experience globally, while responding to control changes and system specification at the speed of today’s DevOps teams. In his session at 20th Cloud Expo, Josh Gray, Chie...
Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true ...

Most DevOps journeys involve several phases of maturity. Research shows that the inflection point where organizations begin to see maximum value is when they implement tight integration deploying their code to their infrastructure. Success at this level is the last barrier to at-will deployment. Storage, for instance, is more capable than where we read and write data. In his session at @DevOpsSummit at 20th Cloud Expo, Josh Atwell, a Developer Advocate for NetApp, will discuss the role and value...
