Bankers beware: Technology is going to get you (and none of us will care)

Technology is about to take a big slice of the traditional banking business. Bankers have been slow to see what's coming, but they're starting to realize what's at stake.

Promise Theory

The way we have created IT systems over the years has been very linear with each individual component being statically configured. If a human makes an error in any one of the many configurations, then the whole system breaks down. Over the years, IT systems have become increasingly complex with multiple layers of abstraction and virtualization making it difficult to enforce stability and gain scalability. Promise theory provides a new way to think about how IT systems rely on each other to form an entire system that businesses can depend. This article will cover the foundation concept of promise theory and give examples of how it is used.

And there's something else wrong with Comcast's Xfinity customer-based Wi-Fi hotspot plan ...

I have, in previous Gearhead articles (first in Comcast's latest bad idea turns your Wi-Fi into everybody's Wi-Fi and then in Revisiting Comcast's Xfinity public hotspot strategy), discussed Comcast's strategy for implementing opt-out Wi-Fi hotspots on their customers' Xfinity gateways. In the latter post I questioned the security of the service and noted that access to the Comcast service isn't as tightly controlled as the company might think.

100Mb/sec Ethernet coming to a car near you?

Hungry ants knock out FiOS service ... again

Everyone keeps asking if the ants actually ate their way through the fiber optic cable and I do not know the answer. What is certain is that they chewed through the outer casing and caused enough damage to knock out TV, phone and Internet service to my house: the Verizon triple no-play.

Microsoft introduces Interflow: Sharing cybersecurity threats in near real-time

Microsoft announced Interflow, a new platform for sharing cybersecurity threats in near real-time. Although it's currently available only in "private preview" for Microsoft Active Protections Program (MAPP) members, security threat information will be shared faster, creating a "collectively stronger cybersecurity ecosystem." In the long run that means protecting people better and more quickly.

Why Facebook's SDN switch won't affect Cisco's customers

Last week, Facebook announced a new product that's supposed to have the networking industry trembling. There were many news stories about Facebook's new homegrown SDN switch, known by the codename "Wedge" that's supposed to be the next big threat to Cisco and the traditional networking vendors. The operating system on the product runs Facebook's proprietary version of Linux called FBOSS.

Leveraging Microsoft Azure as your disaster recovery/failover data center

Microsoft has put out in Preview a technology that will completely change how we view disaster recovery and failover of virtual machines and the benefits of the Cloud! What Azure Site Recovery (ASR) does, in a nutshell, is replicate Virtual Machines (VMs) from an on-premise datacenter to Azure on a regular basis, and then the organization can failover their on-premise datacenter so that the VMs are now running in Azure. AND the kicker, Microsoft is doing this at a cost of US$27 per protected VM per month (with an added cost of $60 to ~$150/mo when the VM is failed over and actually running in Azure, which presumably will being during a test or disaster, and the run time in Azure might be limited to a few hours or few days).

Open Networking: The whale that swallowed SDN

The year is 2011, the Open Networking Foundation has just been formed by the largest Cloud and telecom service providers, software giants and academia – all of whom united at the inaugural Open Networking Summit under the common theme that the networking industry had fallen behind, its closed model stifled innovation and was not keeping up with the rest of the computer science discipline or the needs of emerging application and business requirements.
