In part 6 of this series, I covered the obstacles involved with deploying SDN. In this part, I'll discuss the kinds of changes companies will need to make for successful deployment. To deploy SDN there are a number of pre-requisite changes – both technical and organizational.  The most fundamental and problematic changes involve the need for interdisciplinary teams – the boundaries between business drivers, applications teams, server teams and network teams become blurred. For example, for effective SDN the network team will need an understanding of an application’s network footprint (bandwidth, QoS requirements, security settings, etc).  Similarly the server team will need an understanding of the network infrastructure in terms of packing applications onto virtual machines and migrating these around the data center.  In order to orchestrate the end-to-end applicati...

Have It Your Way By @MJannery | @CloudExpo [#Cloud]

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 man...

Relief for Licensing Headaches By @MJannery [#SDN]

Licensing creates some major headaches for network managers, so I wasn’t surprised to read in a recent SearchNetworking article that “simplified licensing and billing” made the IT wish list for 2015. In the network management space, frustrations revolve around which licensing model to buy (e.g., by device, object, etc.), controlling the price of licenses, and finally, deploying and administering them. Entuity’s licensing approach addresses all three areas, emphasizing ease and customization. Here I’ll focus on deployment and administration. (You can read about our attitude towar... (more)

TAPS and NPBS - On a Collision Course By @MJannery | @CloudExpo [#SDN #Cloud]

TAPs and NPBs are certainly on a collision course and their functionality and use cases are overlapping more and more. Traditionally TAPs were relatively unintelligent - providing pass-through monitoring points (possibly with very limited filtering), passing a copy of the data seen on the network ports straight off to the network intelligence tools (e.g., IDS).  NPBs on the other hand offered much more sophisticated techniques such as advanced and deep packet filtering, packet slicing (excessive payload discard), time stamp insertion (for latency measurements), de-duplication and...

Software Defined Networking | Part 4 By @MJannery | @CloudExpo [#SDN #Cloud]

In part 3 of our SDN series, I covered virtual versus physical infrastructure.  This next segment will cover the three most commonly propounded benefits of SDN: efficiency, agility and security. Efficiency Early, hyper-scale pioneers of SDN such as Google astounded the networking community with the increased network utilization they achieved using SDN.  The industry norm for WAN link utilization is between 30% and 50%, whereas, by deploying SDN, Google drove utilization up to 95% (without impacting critical flows, losing traffic, etc.).  This is primarily due to SDN's holistic ...
