Time to Evolve

I first started getting into VMware around 2003, possibly earlier (I can’t recall exactly when it was). I remember thinking that VMware’s impact on the industry was going to be significant, and I wanted to be part of this industry change. I was right—virtualization like what VMware offers has fundamentally changed the industry. However, just as technology evolves, technology careers must evolve as well. Specifically, my technology career must change and grow. It’s time to evolve.

This need to evolve has been building for a couple years. You’ve probably observed that the amount of VMware-centric content produced here on the site has slowly been replaced by topics like Linux, Docker, Vagrant, Terraform, AWS, Azure, and others. These topics represent where I think my next period of growth and change resides, and after a couple years of slow growth in these areas it’s now time to “put the pedal to the metal” and accelerate things.

As of this coming Friday, March 30, 2018, I will be leaving VMware after a little over 5 years with the company. My time with VMware (as an employee) has been an amazing adventure. I’m thankful to Brad Hedlund for his Continue reading

Penn State secures building automation, IoT traffic with microsegmentation

It was time to get a handle on BACnet traffic at Penn State.BACnet is a communications protocol for building automation and control (BAC) systems such as heating, ventilating and air conditioning (HVAC), lighting, access control and fire detection. Penn State standardized on BACnet because of its openness.[ For more on IoT see tips for securing IoT on your network, our list of the most powerful internet of things companies and learn about the industrial internet of things. | Get regularly scheduled insights by signing up for Network World newsletters. ] “Any device, any manufacturer – as long as they talk BACnet, we can integrate them,” says Tom Walker, system design specialist in the facility automation services group at Penn State. “It’s a really neat protocol, but you have to know the quirks that come with deploying it, especially at scale.”To read this article in full, please click here

Dunning-Kruger in IT Infrastructure

Sitting in a taxi driving to CLEUR 2018 in Barcelona we couldn’t resist but complain about the stuff we’re seeing in real-life networks, resulting in someone exclaiming something along the lines of “I can’t understand how someone could do so many stupid things”

Welcome to the wonderful world of Dunning-Kruger Effect.

Stateful vs Stateless firewalls: Which one to use when?

Firewalls provide traffic filtering and protects the trusted environment for the untrusted. A firewall can be stateful or stateless A stateful firewall is capable of tracking connection states, it is better equipped to allow or deny traffic based on such knowledge.  A TCP connection for example goes through the handshake (SYN-SYN+ACK-SYN), to EASTABLISHED state, and … Continue reading Stateful vs Stateless firewalls: Which one to use when?

OpenPower At The Inflection Point

When IBM launched the OpenPower initiative publicly five years ago, to many it seemed like a classic case of too little, too late. But hope springs eternal, particularly with a datacenter sector that is eagerly and actively seeking an alternative to the Xeon processor to curtail the hegemony that Intel has in the glass house.

Perhaps the third time will be the charm. Back in 1991, Apple and IBM and Motorola teamed up to create the AIM Alliance, which sought to create a single unified computing architecture that was suitable for embedded and desktop applications, replacing the Motorola 68000 processors …

IoT security spending to spike above $1.5 billion in the next year

The market for IoT security products is set to grow sharply, as the general IoT market becomes ever more ubiquitous, according to a report released this month by Gartner Research. While there are numerous drivers behind the increased demand for IoT security, a growing sense that regulatory compliance will shortly become an issue is one of the most pressing.The report lists security as the top barrier to success for IoT initiatives, according to a survey on IoT adoption conducted by Gartner. A big part of the problem, the report said, is that businesses often don’t have full control over which devices and software are being used at each level of a given IoT project.To read this article in full, please click here

NSX Powers a ‘Classroom in the Cloud’ for Illinois Students

 When the technology leaders of Bloomington’s public schools started looking for a way to make advanced, enterprise-level computing and Internet services affordable to students, they went the co-op route and turned to IlliniCloud. IlliniCloud has proven to be a game-changer for a public education system in crisis. The co-op is transforming the technology infrastructures of not just Bloomington’s public school district, but every school district in Illinois with an affordable and efficient model that results in major cost savings for schools, along with upgrades in technology and aging infrastructures.

 

VMware is the backbone of IlliniCloud and a natural fit, according to Jason Radford, CTO of IlliniCloud: “VMware believed in the IlliniCloud. They gave us the tools that were Continue reading
