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.
Cloud computing is changing the way we look at IT costs, according to industry experts on a recent Cloud Luminary Fireside Chat panel discussion. Enterprise IT, traditionally viewed as a cost center, now plays a central role in the delivery of software-driven goods and services. Therefore, companies need to understand their cloud utilization and resulting costs in order to ensure profitability on their business offerings. Led by Bernard Golden, this fireside chat offers valuable insights on ho...

You hear the terms “subscription economy” and “subscription commerce” all the time. And with good reason. Subscription-based monetization is transforming business as we know it. But what about usage? Where’s the “consumption economy”? Turns out, it’s all around us. When most people think of usage-based billing, the example that probably comes to mind first is metered public utilities — water, gas and electric. Phone services, especially mobile, might come next. Then maybe taxis. And that’s ab...

This month I want to revisit supporting infrastructure and datacenter environments. I have touched (some would say rant) upon this topic since my post in April 2014 called "Take a Holistic View of Support". My thoughts and views on this topic have not changed at all: it's critical for any organization to have a holistic, comprehensive strategy and view of how they support their IT infrastructure and datacenter environments. In fact, I believe it's even more critical today then it was a year ago ...

As a group of concepts, DevOps has converged on several prominent themes including continuous software delivery, automation, and configuration management (CM). These integral pieces often form the pillars of an organization’s DevOps efforts, even as other bigger pieces like overarching best practices and guidelines are still being tried and tested. Being that DevOps is a relatively new paradigm - movement - methodology - [insert your own label here], standards around it have yet to be codified a...

For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...

Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...
