Enterprises Have Many Unprofitable Applications, Public Clouds Do Not
Enterprise IT supports many unprofitable applications. Microsoft Exchange, legacy databases, obsolete accounting systems, end-of-life desktop operating systems and much more. Public clouds can, and do, cancel unprofitable products. This is a brutal truth in cloud planning. Takeaways: Enterprise IT supports many applications that are unprofitable to own and maintain Executives and managers are commonly unprepared […]

Response: Docker Networking | Chris Swan’s Weblog
I’ve spent some hours taking a look at Docker containers and how they connect to the network. The short summary is “messy” and better description is “train wreck”. Chris Swan has a 30 minute presentation on his experiences with Docker as part of his company VNS3. Docker Networking | Chris Swan’s Weblog. At this point […]

Less Sales, Simpler Products, Easier Buying
Out of sheer frustration this week, I tweeted this and got a big response: The Back Story I’ve wasted about 60 hours of customers time working with resellers & vendors to get a quote for a relatively simple network upgrade. Neither the vendor staffers or the reseller employees knew how the product was licensed or […]

Cisco On Net Neutrality Isn’t What It Seems
Chambers pointed the finger at Net Neutrality for a slow down in purchasing by carriers in US markets and that he perceives it as damaging to Cisco business interests. I find it more credible that SDN/NFV is slowing capital investments than some far off political change.

Musing: VMware Sells More Services Than Licenses
In their Q3-2014 VMware results, the revenue from "services" is 30% larger than licensing revenue. What does this mean for customers ?

Musing: Subscription License Economics
The rise of software licensing in networking changes some of my assumptions about the 5 year cost of ownership of products. Roughly, lets assume that you are buying virtual appliances like firewalls, DNS/DHCP, IDS/IPS, proxy servers and load balancers and that you pay some type of yearly license to use the product. Capital Upfront The legacy […]

Response: I’m Terrified of My New TV
Smart Televisions are tracking everything you do and sending that data to unknown services: The amount of data this thing collects is staggering. It logs where, when, how, and for how long you use the TV. It sets tracking cookies and beacons designed to detect “when you have viewed particular content or a particular email […]

Blessay: Over-Capitalized and Under-Invested in Human Infrastructure
LEDE: One of the hardest parts of DevOps movement is explaining the unique value to IT Leadership in conventional organisations that rely on ITIL principles. I'm having success by framing the debate in terms of over-capitalised on assets and under-invested in human infrastructure.

Thoughts of My Day: VCE Always Was An EMC Property
EMC announced during it’s quarterly results that it was taking a larger position in VCE. VCE was always an EMC asset, co-operation with partners Cisco, Intel and VMware has never been strong and this simply closes out the current chapter. The end result positions EMC to also be a “IBM style” company with a full […]

Response: HowTo Configure IP Multicast PIM on ECMP| Mellanox Interconnect Community
Today I spent several hours reading up on PIM Bidirectional for an customer implementation on an ECMP networking. I realise that somewhere inside my head there is a lot of IP Multicast knowledge that hasn’t been lost but it is definitely hiding. I had to re-learn a number of concepts before I started feel confident. […]
