Cisco Global Cloud Index (2013 – 2018): Data Center and Cloud Traffic for the Next Five Years

What do our GCI Forecast projections mean for you?

Today, Cisco released the fourth annual update of its Global Cloud Index, or GCI (see media release). For most people who follow cloud-computing, it’s no real surprise to learn that global data center traffic will nearly triple over the next five years or that cloud traffic is expected to nearly quadruple. Examining the trends within the top-line forecast projections is where we begin to see what this growth means for service providers, businesses, and consumers (and how data center networking is being transformed).

For Service Providers and Data Center Operations:

GCI Highlight: The workload density (that is, workloads per physical server) for cloud data centers was 5.2 in 2013 and will grow to 7.5 by 2018. Comparatively, for traditional data centers, workload density was 2.2 in 2013 and will grow to 2.5 by 2018.

The Benefit: An important factor in the rapid expansion of cloud computing is increasing data center virtualization, which provides services that are flexible, fast-to-deploy, and efficient. Virtualized data centers require fewer physical servers and offer great scalability than traditional data centers. This can ease capex and opex pressures (allowing for investment in other areas).

Cisco and Red Hat – All In with OpenStack for the Enterprise

When it comes to driving innovation in next generation data center architectures, open source is clearly at the forefront. A perfect example is OpenStack, which is defining the future of cloud computing across private, public and hybrid clouds. This innovation is being driven by a strong and vibrant community that is taking place in Paris this week for the OpenStack Summit. I’m looking forwarding to reconnecting with friends in the OpenStack community and discussing the recently announced Cisco and Red Hat solution for OpenStack.

Interest in OpenStack as a cloud platform is clearly on the rise. At the recent Cisco Unified Computing System (UCS) launch event in New York City, Cisco and Red Hat introduced the UCS Integrated Infrastructure for Red Hat Enterprise Linux OpenStack Platform (UCSO).  The pre-integrated and validated solution is a major step forward in providing an enterprise ready private cloud solution based on OpenStack.

The Top 5 OpenStack Adoption Challenges – View from Cisco Services’ Experts

November 3, 2014 at 11:34 am PST


openstackOpenStack is gaining increasing industry attention and, while it can deliver huge advantages, some may say it is “hyped”. Although OpenStack has an ever growing range of enthusiastic practitioners and advocates,  as you may be aware, OpenStack is not without its critics – including Gartner - who outline the challenges of OpenStack adoption. It’s therefore generally recommended that OpenStack adopters consider engaging professional services experts to help them avoid the pitfalls

With the November 2014 OpenStack Summit in Paris opening as I write this – you can find us at stand C3 along with our newest acquisition, Metacloud (Stand E37) if you are going - my thoughts turn to the issues and challenges facing our customers when they deploy OpenStack into production projects.  And who better to ask than our Cisco Services consultants who are delivering OpenStack adoption services (which we launched this time last year at the Summit in Hong Kong).

These consultants are at the “coal face” (as we say in my part of the world, Scotland) of OpenStack– they are the experts digging deep in the IT equivalent of the mines working with real customers going live with real-world OpenStack.    More than R&D investigations, these deployments are happening with customers who are betting their business dollars, pounds, yen and other currencies on OpenStack.  However as the video (below) shows, OpenStack has its deployment complexities.  Hence increasing numbers of our customers are engaging Cisco Services to help them on OpenStack.

To share our practical experiences with you, we sat down and came up with our “top 5” adoption challenges list which you may find useful if you are considering or embarking upon an OpenStack deployment:

  1. Cross-domain technical expertise is mandatory
  2. Going deep with Open Source
  3. “It’s just middleware”
  4. Don’t underestimate the learning curve
  5. Expect your OPEX to increase (sorry!)

New Nexus 2348TQ Joins Nexus 2300 Series Fabric Extender Family

There is no doubt that the word transformation is being used to describe pretty much anything to do with the data center, but in all of this, it’s good to remember that little things can make a BIG difference in making day to day data center operations easier.

With simplicity as one of the key tenants, the Nexus 2300 Series Fabric Extenders continues on the same trajectory as previous Fabric Extenders by delivering a solution that, when coupled with Cisco Nexus parent switches, makes adding performance, scale, and operational simplicity to the network access simple.

Today, we add a new member to this 3rd generation fabric extender family – the Nexus 2348TQ, which together with the Nexus 2348UPQ, offers more connectivity options for data centers of different sizes with varying performance and application needs.

The Nexus 2348TQ is a compact, 1RU Fabric Extender that offers:

- 48 x  10G BASE-T host port interfaces

- 6 x 40 Gigabit Ethernet ports for parent switch connectivity

This makes the Nexus 2348TQ an ideal solution for data centers looking to upgrade their server access deployment from 1GBASE-T to 10Gbps speeds and from 10Gbps to 40Gbps connectivity.

 

 

As outlined in my previous blog, all members for of the Nexus 2300 Series Fabric Extenders support:

  • Larger buffers to absorb bursts of traffic for a wide variety of workloads such as multicast feeds, voice traffic, video traffic, and healthcare applications
  • Unified Ports support enabling a flexible LAN and SAN deployment through support for Ethernet, Fiber Channel and Fiber Channel over Ethernet connectivity
  • Support for Cisco’s 40G BiDi optics simplifying migration 10 to 40 Gigabit Ethernet speeds while reusing existing 10G cabling
  • Additional versatile TCAM which can be used for:
    • Advanced features such as ACL classifications and QOS
    • Hardware-capable local flow redirect for architectures that require intra-rack traffic to reduce bandwidth

Bringing Together Nexus 2300 Fabric Extenders and Cisco Nexus Parent Switches

The Nexus 2300 Fabric Extenders can be perfectly paired with Nexus 5600 and 6000s as well as Nexus 7000* and 9000* (*future) to provide a network access solution that combines the flexibility and simplified cabling of a top-of-rack (ToR) designs with simplified management and efficient utilization of an end-of-row (EoR) design. This flexible architecture where the parent switch manages all fabric extender configuration lets you deploy and re-deploy fabric extenders throughout your data center with minimal reconfiguration needed, not only helping reduce operational and capital expenditures, but also allowing your data center network to quickly adapt to application, traffic,  or business needs.

I invite you to learn more about the Nexus 2348TQ and other Nexus 2300s at www.cisco.com/go/nexus2000.

Cloud Services Router

Cisco Cloud Services Router (CSR1000V) sets the standard for enterprise-class networking and security services in a virtual form factor. The CSR1000V is the first platform to deliver multigigabit IPSec performance in Amazon Web Services cloud.

It helps enterprises transparently extend their private networks to the public cloud using the familiar Cisco IOS XE Software CLI and RESTful API, which make sure of easy deployment, monitoring, troubleshooting, and service orchestration.

ASAv

Security continues to be a top concern for organizations looking to expand their network into the cloud. It needs to be a transparent extension of local network and data center policies, allowing data to move securely between those environments. To address this need, Cisco has engineered new versions of our market-leading Cisco Adaptive Security Appliance Next-Generation Firewall (ASA NGFW) and FirePOWER NGIPS solutions specifically for AWS environments.

Now you can create dynamically encrypted tunnels between your local or distributed networks and the cloud; apply consistent security for physical, virtual, and cloud environments; make sure local policies are understood and enforced in the cloud; and deploy a single security strategy across traditional, NFV, SDN, ACI, and cloud architectures.

See you in Vegas!
