Enterprise Networks and the Drive for IPv6

It was not that long ago that whenever I read an article about IPv6, it usually discussed how the IPv4 Address depletion in other countries. At that time, the adoption of IPv6 was coming from other countries that where the v4 address space was depleted, the US Government, or Service Provider. Well fast forward only a few years and you can include Enterprise Networks in that mix.

Driving this IPv6 train for enterprise networks is wireless technology and the enabling by-product, BYOD. Wireless technology, in particular, Wi-Fi has grown from a toy to a requirement in most businesses today. We have moved from 802.11b which gave you a max datarate of a paltry 11Mbps to 802.11n to a max datarate of 450Mbps if you currently deploy the Aironet 3600 Access Point that supports 4x4 MIMO; if not, it’s a max datarate of 300Mbps. Never mind the fact that we will soon see the Wave 1 version of 802.11ac will have a datarate of 1.3Gbps and Oh BTW, Wave 2 promises a scorching datarate of 6.9Gbps!

What Does a Successful Private Cloud Look Like 18 months After Turn On?

In this great article on Cisco’s Private Cloud: Pain and Profit we learn some of the real life lessons of one of the most successful private cloud deployments in the industry.  The detail of how Cisco IT increased agility, lowered costs, and enhanced security with the use of Cisco Intelligent Automation for Cloud for this deployment is located here.  I like using Cisco IT’s experience in their journey to cloud to give us insight into what a private cloud looks like 18 months after first deployment.  Morphing as planned from the first use case of Infrastructure as a Service to being an “Enterprise Store” across multiple service delivery towers is a key theme I predicted and continue to see,  across many customer deployments.  In the image below, we see a typical Service Taxonomy, where Cloud is just one of the icons in the total service catalog.

Cisco eStoreV3

IT-as-a-Service (ITaaS) with underlying automation is bubbling up as critical for corporate IT strategies.  As IT shops increase their level of comfort with  a service catalog, self service and orchestration for compute, virtualization, network, and storage; the attention shifts to other areas such as applications, virtual desktops, and other technology domains such as collaboration technologies.  Let’s take a detailed look at where the Cisco IT eStore and Intelligent Automation for Cloud have gone in those 18 plus months since ignition.  The home page of the eStore shows the current catalog of some key services being offered and other services being migrated over as we speak.  We immediately see Virtual Desktops, and Home & Remote Access in addition the beachhead of IT Infrastructure and Platform Services

Telework: A Manager’s Perspective

The benefits of teleworking—better work/life balance and more flexibility—sure sound great from an employee’s point of view. But from a manager’s perspective, is telework really successful for getting work done? Can a team really be effective if many of the members never work together in person?

Yes, if you create the right policies and environment and give employees the tools they need in order to work productively and be full contributors to their team. Read More »
