Networking Forecast: Cloudy with Increasing Zettabytes

With the onset of cloud, we’re being asked more and more by our customers about the architectural requirements that result from it.  While the customers have an instinct as to what’s needed, there seems to be less actual data to that effect than what they would like.  When confronted with a similar situation over 5 years ago about the network, we developed the Cisco Visual Networking Index which focuses on the amount of traffic carried across the network to the end user to help gauge the extent of infrastructure needed to support the data deluge.  Now with the network becoming inextricably linked to the data center and cloud, we realized we need to look at the other half of the equation as well to get a truly comprehensive architectural view.  To achieve this, we reviewed 30Tb of data each month, more than 45 million speed tests, analyst forecasts, and inputs from our customers.  The result?  The inaugural Cisco Global Cloud Index, released today.

Here are a few takeaways to consider:

  • Global data center traffic is estimated to grow four-fold to reaching a total of 4.8 zettabytes annually by 2015.
  • The vast majority of the traffic – 76% — surprisingly, doesn’t even hit the network but instead stays within the data center itself, as workloads are constantly being migrated to different virtual servers.
  • Of the total data center traffic, about 11%, or 130 exabytes of annual data center traffic in 2010 is considered part of the cloud  – however that amount is going to grow significantly in the next half decade, reaching more than a third of data center traffic, or 1.6 zettabytes annually, by 2015.

Cloud may be the concept-of-the-day for the industry, but with growth like that, it shouldn’t be discounted as a passing fad but rather a lasting trend whose impact will fundamentally affect network architectures going forward. Read More »

Multitenancy in the Data Center: Putting a New Paradigm to Work

Imagine if you were a building contractor and a client came to you and said, “I need you to build a commercial facility suitable for a variety of occupants, including a 24-hour machine shop that consumes massive amounts of electricity, a workshop for the disabled full of assistive equipment, and a rare gems dealer who requires maximum security.  Oh – and by the way – they’ve all signed 5-year leases, so your design will have to anticipate their future needs.”

OK, so what has an ancient Scottish castle got to do with the Gartner Data Center Conference in London?  This doesn’t sound like what I usually blog about!

How to Make the Business Thankful for IT. Give them Apps!

November 23, 2011 at 11:46 am PST

Think about it, when was the last time the business said “thank you” to IT? It’s probably been a while. Unfortunately, all too often we hear complaints that IT is too slow, or that IT is the department of “no”.

Deploying a private cloud is one way to help turn IT into the department of “yes”, with faster and more responsive IT service delivery. The customers of Cisco Intelligent Automation for Cloud have compressed the cycle time for IT provisioning from weeks to minutes. That means that project managers and application developers no longer have to wait for IT – they can speed up their projects and get business applications up and running more quickly.

And if there’s one golden rule to remember for your private cloud solution, it’s that the business wants apps. They’ll be thankful if you can provision and manage their applications in a cloud environment with consistency, reliability and speed.

So if you’re interested in on-demand application delivery for your private cloud, check out this presentation from Cisco Intelligent Automation and our ecosystem partner rPath:

The Idea That Changed the World

November 23, 2011 at 10:35 am PST

Once in awhile, an idea comes along that changes everything.

Well, this isn’t one of those ideas. But after 25 episodes of Partner Update, perseverance has to count for something.

The goal of Partner Update was simple: create a short, five-minute newscast that would get partners up to speed on the latest Cisco headlines. While our first go at it was nearly unwatchable, the newscast has grown and evolved and now features a varied medley of news, partner interviews, highlights, and updates.

Of course, Partner Update isn’t just for our partners, it’s about our partners. During our 25 episode stint, we’ve highlighted dozens of extraordinary Cisco partner achievements, from new data centers, to social media campaigns, to cool gadgets and products. We’ve even featured your tweets, videos, and Facebook posts.

Here’s a short trip down Partner Update memory lane featuring partner interviews, bloopers, highlights, and behind-the-scenes footage.
