Everyone is talking about the transition to IPv6 in the run up to the June 6th launch of the IPv6 Internet. Most of the discussion has focused on the technical details of various approaches – 6rd vs. DS-Lite vs. CGNAT for example. However, what we haven’t seen is an effort made to look at the economic impact of the choice between IPv4 extension vs. IPv6 transition and back it up with some real world data. A few months back we asked telecommunications analyst Nav Chander of IDC (pictured right) to evaluate and publish the results of an economic analysis of the IPv6 options. This is a crucial and timely topic because operators are faced with important decisions about which transition technologies to use, when to implement them, and where in the network.
We’re pleased to report that Nav is finished and is ready to reveal the results of his findings. To keep the scope of his analysis within a reasonable boundary, he initially focused on just one scenario: that of a wireline carrier considering the deployment of a Carrier Grade NAT-only implementation (which basically just extends the life of IPv4 with no IPv6), or migrating to IPv6 with a combination of CGNAT (for short term IPv4 extension) and while new customers were deployed with 6rd.
The results of this study are detailed in a new Read More »
As we start off this New Year, how about including a resolution to improve application delivery? In Best Practices for Application Delivery in Virtualized Networks – Part I , we covered key application delivery challenges that have come up due to the complexities of managing the many types of applications that enterprises use today, and further complicated by data center consolidation and virtualization. We then covered some best practices, courtesy of Dr. Jim Metzler’s 2011 Application Service Delivery Handbook, which recommended taking a lifecycle approach to planning and managing application performance.
A key step to the lifecycle approach is to implement network and application optimization tools, such as WAN Optimization solutions and Application Delivery Controllers, including server load balancers. Of course, these solutions are not new to the market and already address many of the needs that exist with delivering enterprise applications in virtualized data centers -- namely, the need to ensure network reliability, availability and security for users accessing these applications. In this post, we will discuss a recent study by IDC, where IT decision makers across Europe and the US spoke out about their strategies for using server load balancers to deal with emerging challenges.
. What important attributes do you look for in your server load balancers?
It’s been said that marketing is telling the truth attractively. My spin on that definition is that “telling the truth is the most effective form of marketing.” That’s exactly how I approach life here in the Marketing organization at Cisco. Read More »
The mighty FlexPod is also the subject of a recent whitepaper by IDC titled “Accelerating Converged Infrastructure with the FlexPod Datacenter Solution and the Support Alliance.” Cisco Partner IronBrick spoke to IDC for the white paper about its experience selling FlexPod and provided some insights on what their customers are looking for.
IronBrick customers are seeing “rapid data growth, have concerns around operational and resource limitations, have physical datacenter issues regarding space, power, and cooling, and have the desire to deploy IT solutions that enable nimble response to today’s dynamic and fast-moving application demand,” according to the whitepaper.
So guess what satisfies all of their customer needs? Read More »
Summers tend to be a bit cool in San Francisco, but acceptance of Cisco’s Unified Service Delivery (USD) solution by Service Providers searching for the best path to cloud is heating up. We’re excited at the progress so far -- including recent records set by the Cisco Unified Computing System (UCS) which just placed 3rd globally in the x86 blades category in a recent IDC report. A little over two years ago people questioned Cisco’s entry into the compute segment of the data center. The large number of Cisco customers have proven that innovation that brings new levels of efficiency to the data center wins out every time. We’re proud of our customers and the services they’re bringing to market more quickly using the Cisco USD solution and its key foundation technologies like Cisco UCS.
Industry analysts are also seeing a need for an end-to-end solution like Cisco USD and noting the importance of resource optimization, management consolidation, service improvements, and cost reduction as fundamental tenets of efficient cloud service delivery.
Below is a short video commentary by IDC analyst, Courtney Munroe, VP, Worldwide Telecommunications. Courtney talks about the market challenges SPs face and how they can benefit from a transition to Cloud-delivered services. Pay special attention to the core things he believes SPs must address for Cloud: virtualized fabric for the computing platform in the data center, how the data center and the network work together and security across the entire delivery chain.
