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.

There are many considerations when moving applications from on-premise to cloud. It is critical to understand the benefits and also challenges of this migration. A successful migration will result in lower Total Cost of Ownership, yet offer the same or higher level of robustness. Migration to cloud shifts computing resources from your data center, which can yield significant advantages provided that the cloud vendor an offer enterprise-grade quality for your application.
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical...
Manufacturing has widely adopted standardized and automated processes to create designs, build them, and maintain them through their life cycle. However, many modern manufacturing systems go beyond mechanized workflows to introduce empowered workers, flexible collaboration, and rapid iteration. Such behaviors also characterize open source software development and are at the heart of DevOps culture, processes, and tooling.
Containers are revolutionizing the way we deploy and maintain our infrastructures, but monitoring and troubleshooting in a containerized environment can still be painful and impractical. Understanding even basic resource usage is difficult - let alone tracking network connections or malicious activity.

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud wit...
There are so many tools and techniques for data analytics that even for a data scientist the choices, possible systems, and even the types of data can be daunting. In his session at @ThingsExpo, Chris Harrold, Global CTO for Big Data Solutions for EMC Corporation, will show how to perform a simple, but meaningful analysis of social sentiment data using freely available tools that take only minutes to download and install. Participants will get the download information, scripts, and complete en...
IT data is typically silo'd by the various tools in place. Unifying all the log, metric and event data in one analytics platform stops finger pointing and provides the end-to-end correlation. Logs, metrics and custom event data can be joined to tell the holistic story of your software and operations. For example, users can correlate code deploys to system performance to application error codes.
Overgrown applications have given way to modular applications, driven by the need to break larger problems into smaller problems. Similarly large monolithic development processes have been forced to be broken into smaller agile development cycles. Looking at trends in software development, microservices architectures meet the same demands. Additional benefits of microservices architectures are compartmentalization and a limited impact of service failure versus a complete software malfunction....
