Programmability and SDN are not the same

Network programmability means democracy, means freedom, freedom to program across all layers and entities, software or hardware – depending on your needs. Is SDN required to have network programmability? Not at all. Does the SDN architecture leverage network programmability? Yes, of course.  So, why do many people equate network programmability and SDN? Read More »

Introducing Cisco Unified Fabric Innovations: Cisco Dynamic Fabric Automation, Nexus 7700 Switches, and F3 Modules

Cisco today introduced Application-Centric Infrastructure as the vision for Next Generation Data Center architecture, built for both today’s physical and virtual workloads as well as tomorrow’s highly dynamic Cloud-based, and performance-intensive big data application environments. Please check out Padmasree Warrior’s blog or Cisco Unified Fabric to learn more.  

What I would like to share with you is how we are evolving the Cisco Unified Fabric to deliver operational simplicity through superior integration.

Introducing Cisco Dynamic Fabric Automation (DFA)

Delivering Operational Simplicity through Superior Integration

As organizations accelerate private and public cloud deployments, IT organizations and data center networks must evolve to meet rapidly changing and growing requirements.  Virtualized and cloud environments require more agility and simplicity to quickly deploy and migrate virtual machines. IT organizations, on the other hand, are challenged with operational complexity, architectural rigidity and infrastructure inefficiency with manual processes, disjointed provisioning, deficient software overlays, static resource allocations and disruptions when growth is needed.

The good news is that Cisco continues to evolve its Unified Fabric to address these needs. The new Cisco Dynamic Fabric Automation delivers unsurpassed operational simplicities through superior integration. It does this by …. Read More »

Cisco Professional Services for Cloud Ranked #1 in IDC Survey – Announced at CiscoLive!

Having been part of the team who developed the Cisco Cloud Enablement Services, our professional services to help customers enable and adopt cloud computing, I was absolutely delighted watching the CiscoLive! keynote yesterday to hear Padmasree Warrior announce the results of the March 2013 IDC market research study that showed Cisco come out on top for cloud professional services [Source: “2013 U.S. Professional Services Opportunities Related to Cloud Services”, IDC Doc # 239862, March 2013].

In this survey, as  the chart below shows (reproduced with the kind permission of IDC), respondents indicated that Cisco professional services were used most often across all of the three cloud categories that IDC measured: cloud applications, cloud application platforms, and cloud infrastructure.  Ahead of Accenture, Microsoft, IBM, Oracle/Sun, HP and others.

VIRL Saves the Day!

One of the themes of my posts is that the overall ONE strategy, including virtualisation, would create an environment for network systems development that would meet the expectations of systems developers accustomed to the “enterprise” style of software development.

An enterprise systems developer expects the required systems resources for software development to be readily available for development and test purposes. When those resources constitute web application servers and databases, this is trivial with virtualisation, and generally unremarkable in today’s enterprise environments.

When those resources constitute expensive, high-end, routing and switching platforms, though, life is not that straightforward. A major part of a network engineer’s time is spent on obtaining, connecting and configuring network equipment for demonstration and test purposes. You can’t just try an idea out when it occurs to you, as the required network platforms often can’t be available when, and in the configuration, you want.

But imagine what you could do if those network resources were available at a click of a button. What if network engineers had the same capabilities as software engineers to create virtual environments of near perfect fidelity? Well, with the technology of the Virtual Internet Routing Laboratory (VIRL), that we are demonstrating at Cisco Live in Florida, that possibility is getting closer. Read More »

Simplifying Multi-Provider WAN Designs

This week, at Cisco Live Orlando, we are introducing a brand new EIGRP feature called Over-the-Top (OTP). EIGRP OTP is focused on simplifying the deployment of branch networks utilizing an EIGRP end-to-end solution over public and private networks. This simplicity is further enhanced with EIGRP use of Over-the-Top (OTP) to support multiple service provider IP networks.

Connecting sites over a WAN cloud can be complex, especially when supporting thousands of branch locations, multiple service providers, and feature requirements like encryption. Aside from the configuration challenges, operationally, customers need to filter routes while avoiding routing loops during redistribution, which makes it harder to troubleshoot the network.

The EIGRP Over-the-Top (OTP) solution simplifies multi-provider IP WAN network designs. It simplifies the interface with the WAN providers and facilitates an end-to-end EIGRP network, which is easier to troubleshoot.

How simple is EIGRP OTP to deploy? Read More »
