Hybrid Devops – Software Defined Disruption

Businesses have been and will continue to be disrupted by software agility and innovation. If you have any questions, just ask, if they are still in business, Movie Rental Companies (Netflix), Taxi Companies (Uber), and Retail Companies (Amazon) to just name a few areas (companies that disrupted an industry with Software). Software defined disruption has changed the landscape and continues to drive tremendous business value like never before. What’s most exciting is that we have not seen anything yet compared to what the Internet of Everything (IoE) will disrupt! To understand software disruption better and determine the innovation opportunities it helps to take a look at the typical devops model today, challenges, and opportunities.

The typical devops model is represented the figure below:

The Network After 25 Years of Cisco Live!

#clus1A lot can change in 25 years. At the first Cisco Live (then known as Networkers conferences) in 1989, 200 geeks gathered for the inaugural event. Fast forward to three weeks ago, when we welcomed a whopping 25,000 attendees into the arms of our namesake, beautiful San Francisco.

We heard there was some interest in how the network performed at the show, so I wanted to share some of the interesting statistics about the network at Cisco Live! I shudder at the thought of the ancient network from 25 years ago. So here we go:

This year we saw 30,705 unique devices, with 7000 in the theater for John Chambers’ keynote.

Top 10 Reasons to Upgrade to the 7.4 MD Software Release

As the famous saying goes, “Good things come to those who wait”. Delayed gratification – person’s ability to forgo a smaller reward now for a larger reward in the future – has been linked to better life outcomes as demonstrated by the often cited Stanford Marshmallow experiment and others. In most cases though, it requires a degree of self-control not easily achievable in today’s fast paced, ever-changing world with new mobile devices, protocols and technologies.

If you are one of the Cisco Wireless customers currently deploying Release 7.0 MD and waiting for the next Cisco Wireless Software Maintenance Deployment Release, the wait is over!

Release 7.4.121.0 has achieved Maintenance Deployment (MD) status.

Release 7.4.121.0 is the recommended MD release for all non-802.11ac deployments. For 802.11ac deployments, Release 7.6.110.0 (Release 7.6 Maintenance release 1) is the recommended release.

For additional details on Software Release Recommendations and Guidelines, see Guidelines for Cisco Wireless Software Release Migration

Below are top 10 reasons (in no particular order) to upgrade from the current 7.0 MD release to the latest 7.4MD Release.

10. FlexConnect (improved and rebranded H-REAP) with efficient AP upgrade across WAN, BYOD policies support, Flex ACLs and split tunneling. Read More »

Tablets in K-12 Education: Design Your Wireless Network for Tomorrow

Whenever I travel for business, I take my tablet along. It connects me to work email, it plays my favorite music and it allows me to catch up on Red Sox games during baseball season. It is also a filled with pre-K apps for my son to learn his numbers and letters in preparation for kindergarten.

This use of the tablet for engaging young minds is probably no surprise to most parents, and it is no secret that tablets are changing the way our children are learning both in and out of the classroom. More and more schools are interested in ramping up the role of technology in the classroom, and with this in mind, we put together a webinar for K-12 educators on the very topic of tablets in K-12 education.

Using Mobility to free you from the desktop – What we’ve learned about deploying Cisco Unified Mobility

Last week, I described what Cisco Unified Mobility is and what it does for me and the other thousands of employees at Cisco.  Today, let me tell you about the deployment process and what we learned.

Cisco IT Implementation

Cisco Unified Mobility requires our Cisco Unified Communications Managers to be on version 7.1 or above, and we started deploying the service soon after we’d upgraded to 7.1.  We deployed Cisco Unified Mobility in each of our 13 Cisco Unified Communications Manager clusters, rolling out the service on a site-by-site basis. This gradual transition process helped to smooth the impact of supporting users and the potential for spikes in outbound calls as employees began working with the SNR feature.  At first, we worried that a large number of calls going out to mobile phones from Cisco sites might overwhelm smaller outbound trunks, but so far we haven’t seen any problems there.  Also, our gradual site-based rollout made it easy to avoid countries that do not allow outbound calling from our private VoIP network to the PSTN (primarily in the Middle East, and in India).

One implementation decision may be a surprise:
