The World of Many Clouds

Cloud – the combination of computing, networking, storage and management – fundamentally changes the way businesses deliver services to improve economics and flexibility.

While the notion of “the Cloud” is often thought of as a single entity, in fact, there are many types of clouds: private clouds, public clouds, hybrid clouds, and even interconnected communities of clouds serving different verticals, like government, health care or finance. Indeed, we live and work in a world of many clouds.

Just in time for the holidays: cloud data!

With the emergence of cloud computing, our customers have looked for real-world data that could help them understand the nature and scope of the cloud phenomenon. But that kind of data has not been readily available.

Not satisfied with this lack of information, a research team at Cisco reviewed 30Tb of data each month, more than 45 million speed tests, analyst forecasts, and inputs from our customers.  The result?

Today, Cisco released its first Cisco Global Cloud Index report — a forecast of IP data center and cloud-based traffic growth and trends worldwide, 2010-2015.

Similar to the Cisco Visual Networking Index in purpose and approach, the Global Cloud Index enables organizations to make strategic networking and management decisions and governments to make informed public policy decisions.

Some highlights from the report reveal: (all data global)

1.    Cloud traffic is growing twice as fast as data center traffic, increasing from 130 exabytes in 2010 to 1.6 zettabytes annually by 2015

  • 1.6 zettabytes is approximately equivalent to 22 trillion hours of streaming music
  • 76% of this traffic will remain within the data center itself
  • By 2015, 57% of all data workloads will be processed in the cloud Read More »

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 »

Cbeyond’s Brent Cobb Talks with Cisco about Customer Intimacy and IPv6 (Part 2 of 2)

This is the second section of our two part interview with Brent Cobb, Cbeyond’s Chief Revenue and Customer Officer. The first part is located here.

How will IPv6 Transition affect your customers?

Brent Cobb:

Cbeyond has been watching IPv6 unfold since the late 90s. Today the company is in the implementation phase of its transition to support IPv6, and we’ve chosen Cisco’s Carrier Grade v6 (CGv6) implementation as its solution. To us IPv6 will impact how the plumbing of the Internet works – but we try to take the really sophisticated technology of operating a network and applications out of the discussion and service delivery to the small business into the discussion. The majority won’t be impacted directly by IPv6 because Cbeyond will make changes within our network, within our data centers, and within our application environment so our customers don’t have to understand the difference between v4 and v6. It will be transparent to our customers because we’ll handle the complexity.

The Journey to the Cloud

While there is more and more talk of cloud computing lately,  it’s not clear how data center managers can integrate this into their capacity planning in a standardized way. Most of the various approaches to both internal and external cloud computing offered today work differently from vendor to vendor, and vary by the type of application problem being solved or cloud service required. For example a business may choose to access an application in the cloud such as Salesforce.com, or choose to move a particular infrastructure or platform stack to an internal cloud technology or external cloud provider.  And for cloud computing to be truly valuable, it needs to offer the data center manager a range of technologies that work seamlessly together, deploying services as required to meet business needs.
