I have worked in IT since 1995 and never learned programming. Sure, I can do a little HTML, and years ago, I learned just enough Perl to configure MRTG, but I have never written a program. The good old CLI has kept me very busy and brought home the bacon.
Therefore, I have opened an account at codecademy.com. I will start with Python and Java. I see many late nights in my future.
I have thought about learning code, but I could never think of an app I wanted to write. Now Cisco is bringing together networking and programming. Cisco is not only making APIs available, Cisco is contributing code to the open source community. In fact, Cisco has created a Data Center repository, a Nexus 9000 community, and a general Cisco Systems repository on GitHub.
Cisco has recently overhauled the developer program and its content. The new DevNet website is filled with developer information on products such as AVC, Collaboration, UCS, CTI, Energywise, FlexPod, UCS Microsoft Manager, Jabber, onePK, XNC, Telepresence.
Cisco is bringing the networking and programing worlds together and this stubborn old networker is finally onboard.

As previously introduced in my colleague Song’s blog post, Cisco Prime Service Catalog is an industry-leading IT service catalog solution for any managing any type of service request – from desktop to mobility to data center. If you aren’t familiar with our product already, make sure to watch this video:
In most organizations, there is no single system or “app store” that end-users can use to request all the IT tools and services they need to do their job. There are typically different siloed processes for ordering, fulfilling and tracking each of those IT resources (e.g. mobile devices, laptops, applications, infrastructure, access to systems). And with the continued proliferation of new technologies and applications, this has become increasingly frustrating for end-users – and more challenging for IT service delivery teams. Cisco Prime Service Catalog provides a modern and unified approach to solve these problems, with a simple and user-friendly service catalog that eliminates the complexity of ordering services across these different IT silos.
The results? Increased productivity for end-users. Faster and more efficient IT service delivery. Higher IT customer satisfaction scores and greater IT-business alignment.
So what’s new in the latest version of Cisco Prime Service Catalog? Version 10 is packed with several new features and enhancements, including:
A next-generation HTML5 user interface with new capabilities. The user experience for our IT service catalog was inspired by consumer internet sites and app store concepts, and developed in collaboration with Cisco’s own IT organization. In this modern new user interface, end-users can easily search and filter for different apps and tools to find specific services, select and configure the options they want, and place them in their shopping cart.
Depending on who they are in the organization, end-users will have a different view of the catalog – based on role-based access controls. So your employees can search and browse through the catalog to find and download different mobile and desktop apps:
Flexible policy frameworks to enable greater control of available IT services. For example, we’ve added new quota functionality for managing IT resource requests. Quotas are especially useful when automating the delivery of finite resources like storage or compute capacity, or managing against departmental budgets or grants. Another examples is our new policy alerts and enforcement for lease expirations, to notify users before auto-expiring their access to particular resources. Providing your users with the option to automatically extend or cancel their lease can improve resource utilization and increase customer satisfaction.
Finance and demand management enhancements for showback and a “bill of IT”. All IT service providers charge for their services, but the concept of pricing and costing is still new for many enterprise IT organizations. Showback is a typically starting point, and we’ve added new capabilities to differentiate pricing for different classes of service (e.g. gold, silver, bronze) for different departments or tenants. Chargeback is often challenging for many IT departments to implement organizationally, but showback can provide a “bill of IT” with the details of who is using how much of what – without actually implementing cross-department charging. In other words, it shines a light on actual IT consumption and costs. In this new release, we’ve also made it easier to integrate with 3rd party billing systems and tools (e.g. Cloud Cruiser) to help automate financial cross-charges between departments
You may have heard the buzz about the internal Cisco IT deployment of Cisco Prime Service Catalog, dubbed the “eStore”. It’s been featured in a number of articles in the media as the internal enterprise app store that powers Cisco’s BYOD and mobile apps program – and provides Cisco employees with a one-stop shop for all IT services (from desktop to data center). If you’re attending Cisco Live in Milan later this month, you can learn more about the case study in this “Inside Cisco IT” session here.
Another service catalog case study that we’re featuring at Cisco Live Milan is Steria. Steria is a great example of one of our service provider customers in Europe; they’ve used Cisco Prime Service Catalog to enable on-demand, self-service delivery for a broad range of IT workplace services, including desktop and mobile applications. You can read more in my earlier blog post – or if you’ll be in Milan, check out the session here.
During the week of Cisco Live Milan, you will also hear more about Cisco Prime Service Catalog version 10.0 in the context of our soon-to-be-announced new release of Cisco Intelligent Automation for Cloud (IAC). Cisco Prime Service Catalog is one of the bundled components within this cloud management software solution, so the enhancements in version 10 are also reflected in the upcoming new release of Cisco IAC. You can join one or more of the Cisco Live Milan sessions listed here to learn more about Cisco IAC.
In this episode of Engineers Unplugged, Michael Letschin (@mletschin) and Hans De Leenheer (@hansdeleenheer) discuss the history behind software defined and predictions for what the future holds for applications and developers. If hardware is an enabler and not a limit, what then? How does this impact developers? Let’s listen in:
Behold the developer-unicorn: lean and mean.

It’s no secret that Fabric-based infrastructure appeals to the ‘here-and-now’ -- and for some -- the future, of computing because of “one-time setup” capabilities and ability to scale to larger compute needs as they arise. A single, unified fabric and solid-state memory combines powerful server capabilities and advanced networking in an easy-to-manage infrastructure made even more dynamic through the ability to support virtualization. Sounds like a mouth full, right?
Bottom line: the necessities your business are dependent on IT. A unified data center allows business systems to function more efficiently and cost effectively. Drop solid-state memory into the mix to further accelerate application performance, and your business will be humming along like never before.
Unleash the potential of your IT by learning more about the business advantages of application acceleration with solid-state systems. By attending this one-hour webinar on January 23, 2014 you will get a first look at Cisco’s new solid state memory offerings.
At the heart of the transition to cloud computing is on-demand provisioning of a wide variety of applications, linear scalability of resources, and non-stop operation at lower total cost. With the increasing frequency of rapid provisioning of data-intensive applications in the cloud, organizations are increasingly challenged to better scale and manage network and storage environments without business disruption. This necessitates a network that provides uniform latency, high bandwidth, full utilization of all paths, and configuration simplicity.
The Cisco Nexus® 9508 40GbE data center Ethernet switch was recently tested by Lippis report and turned in remarkable performance results, while supporting 288 40GbE ports for the highest 40GbE port density of any switch tested to date. Cisco Nexus 9508 performed with the best overall store-and-forward latency of core switches tested to date, while providing consistent latency across all packet sizes at line rate. In addition, it demonstrated 100% throughput (i.e. without dropping a single packet!) across all 40GbE ports for a wide range of packet sizes. This is key to public and private cloud providers seeking aggregation and core networking technology that underpins large-scale, highly virtualized data centers and converged storage systems with support for disparate workloads having a wide range of performance requirements.
The industry-leading 40GbE density and performance of Cisco Nexus 9508 enables data center IT to upgrade aggregation network infrastructures from 10GbE to 40GbE to complement the shift in server networking from GbE to 10GbE. Having extremely impressive cross sectional bandwidth and latency numbers, the Cisco Nexus 9508 can also excel for aggregation and core infrastructure applications in traditional, cloud data centers as well as hyper-scale data center environments. Cisco Nexus 9508 is also optimal network infrastructure for high performance cluster computing applications, for example, for large-scale data analytics and low-latency trading applications.
For unicast traffic, Cisco Nexus 9508 delivered store-and-forward latencies ranging from 1.6 microseconds for 64B packets used in transaction workloads to 3.5 microseconds for 9KB packets used in data-intensive, large-file applications. The latency variation ranged between 1 to 3 ns, allowing consistent latency across all packet sizes at line rate. These are by far the lowest latency measurements observed by Lippis Report in core switches to date (the previous record for modular switch latency was 2.2 to 11.9 microseconds, at the same packet range, however at much less density).
For IP multicast traffic, the Cisco Nexus 9508 demonstrated store-and-forward latencies ranging from 1.6 microseconds for 64B packets to 3.5 microseconds (3465.3 ns) for 9KB packet forwarding IP multicast traffic faster than any other core switch observed in Lippis core switch tests.
The Cisco Nexus 9508’s congestion management is excellent at nearly 78% of aggregated forwarding rate as percentage of line rate during congestion conditions for L3 traffic flows, but when considering the density of ports supported and sheer magnitude of the traffic flow, the Cisco Nexus 9508 achieved congestion management at a scale never before attempted.
The Cisco Nexus 9508 also demonstrated 100% throughput as a percentage of line rate across all 288 40GbE ports for unicast traffic. In other words, not a single packet was dropped while the Cisco Nexus® 9508 was presented with enough traffic to populate its highly dense 288 40GbE ports at line rate.
