It’s always been my philosophy that we should make it as easy as possible for our prospects to write us checks.  Sounds flippant, but I believe it is sound business philosophy. It’s been interesting to me to see how customers have wanted to buy infrastructure software, and how it has changed over the years. Back in the ’90s and early 2000’s, most network management vendors charged for their software per interface or per port, and we did as well.  Around 2004 and 2005, we started receiving requests for device-based pricing, since it was difficult for end users to know just how many interfaces they had (but they knew how many devices were in inventory).  So we acquiesced, and converted to device based pricing.  To do this, you need to make assumptions about the average number of ports per networking device (or interfaces per Bladeserver, etc.). A couple of years late... (more)

Software Defined Networking | Part 2 By @MJannery | @CloudExpo [#SDN #Cloud]

In our initial part in this blog series on SDN, I gave a quick background overview.  This part of the series will cover overlay SDN and underlay SDN. SDN technologies are broadly split into two fundamentally different paradigms - "overlay" SDN and "underlay" SDN.  With overlay SDN the SDN is implemented on top of an existing physical network.  With underlay SDN, the fabric of the underlying network is reconfigured to provide the paths required to provide the inter-endpoint SDN connectivity. Overlay SDN (e.g., VMware NSX and Contrail) use tunneling technologies such as VXLAN, STT ... (more)

He Said / You Said By @MJannery | @CloudExpo [#Cloud #SDN]

Some of the network gear vendors cast a wary look at network management vendors, particularly those who do continual, automatic discovery of the network inventory and connectivity.  Why? We know what’s actually out there, and what’s actually being used. We had one customer in the insurance industry who was due to renew their maintenance agreement with a large, well-known network gear vendor. The typical scenario was to be handed a spreadsheet by the salesperson, listing the serial numbers of the network devices they had purchased, together with a summary of maintenance charges. ...

The Non-Tangibles Become Tangible By @Entuity | @CloudExpo [#Cloud]

We recently changed over the entire phone system in our London office.  After four years, the equipment failed, and it was time to update.  As we did so, we also changed vendors.  Why? It occurred to us that, for four years, we had put up with horrible support – we were the victims of fraud at one point, and the vendor did nothing to support us with the main telecom provider.  The phone system could go down for a day before they came out to repair it.  No big deal, right?  What high tech software company needs to communicate to the outside world? So it was time to put in a new ph... (more)

Networking in 2015 - SDN and IPv6 | Part 2 By @MJannery [#SDN]

In Part 1, I shared my thoughts on SDN in 2015, after reading Sean Michael Kerner’s article in Enterprise Networking Planet.  This post will cover a few of my thoughts on IPv6. Once the initial scares surrounding IPv4 address exhaustion passed, enterprises have taken a relaxed attitude to deploying IPv6 (if they deploy it at all).  Given that there are sufficient IPv4 addresses for enterprises to use internally and well proven solutions for implementing NAT at the LAN/WAN boundary, there doesn’t appear to be a compelling reason for enterprises to adopt IPv6 internally in 2015.  ...
