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. 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. 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. 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. 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. 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. 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. 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.
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.
DevOps is speeding towards the IT world like a freight train and the hype around it is deafening. There is no reason to be afraid of this change as it is the natural reaction to the agile movement that revolutionized development just a few years ago. By definition, DevOps is the natural alignment of IT performance to business profitability. The relevance of this has yet to be quantified but it has been suggested that the route to the CEO’s chair will come from the IT leaders that successfully ma...

As we enter the final week before the 19th International Cloud Expo | @ThingsExpo in Santa Clara, CA, it's time for me to reflect on six big topics that will be important during the show. Hybrid Cloud This general-purpose term seems to provide a comfort zone for many enterprise IT managers. It sounds reassuring to be able to work with one of the major public-cloud providers like AWS or Microsoft Azure while still maintaining an on-site presence.

As software becomes more and more complex, we, as software developers, have been splitting up our code into smaller and smaller components. This is also true for the environment in which we run our code: going from bare metal, to VMs to the modern-day Cloud Native world of containers, schedulers and microservices. While we have figured out how to run containerized applications in the cloud using schedulers, we've yet to come up with a good solution to bridge the gap between getting your conta...

DevOps theory promotes a culture of continuous improvement built on collaboration, empowerment, systems thinking, and feedback loops. But how do you collaborate effectively across the traditional silos? How can you make decisions without system-wide visibility? How can you see the whole system when it is spread across teams and locations? How do you close feedback loops across teams and activities delivering complex multi-tier, cloud, container, serverless, and/or API-based services?

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...

DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain. In this power panel at @...

At its core DevOps is all about collaboration. The lines of communication must be opened and it takes some effort to ensure that they stay that way. It’s easy to pay lip service to trends and talk about implementing new methodologies, but without action, real benefits cannot be realized. Success requires planning, advocates empowered to effect change, and, of course, the right tooling. To bring about a cultural shift it’s important to share challenges. In simple terms, ensuring that everyone k...
