How I’ve Attempted to Blog More in 2017

This post has been sitting in the “drafts” folder for a while now. Clearly, since it’s August and is therefore a little late to be deciding on a plan that is supposed to carry through all 12 months of 2017. Regardless, I think it’s still worth sharing how I’ve attempted to increase the frequency of my blogging. My basic goal for 2017 is:

Create more content in 12 months than I ever have before in order to a) significantly build up the depth and breadth of knowledge on my blog, b) increase my skills as a writer, and c) continue to build this blog and the readership as a key part of my online persona and brand.

In order to achieve this goal, I’ve identified a couple of tactical objectives:

  1. Reduce the friction between me and the keyboard; make it possible to “just write”.
  2. Be able to “just write” anywhere. At home. On vacation. In a waiting room. On an airplane. I should also be able to start a post in one location and pick it up again in another. Indirectly this means I need to be able to write on any of my computers or mobile devices.

Liveblog: VMworld 2017 Day 2 Keynote

This is a liveblog of the day 2 keynote at VMworld 2017 in Las Vegas, NV. Unlike yesterday, I wasn’t accosted by the local facilities team trying to get a seat at a table in the bloggers/press/analyst area, so that’s an improvement over yesterday. While I’m aware of (most, if not all, of) the announcements that will be made today, I’m still looking forward to the keynote.

Promptly at 9am, Pat Gelsinger takes the stage to kick off the day 2 keynote. He quickly recaps yesterday’s announcements and activities, and then rapidly dives into day 2. First up is a “fireside chat” with Michael Dell.

Gelsinger brings Dell onto the stage and they dive into a number of questions submitted by folks.

  • Gelsinger fields the first question, which is regarding VMware support. He calls on customers to be sure to let VMware know if support, services, products, etc., don’t meet their expectations. Gelsinger refers back to Skyline, which was brushed off yesterday, as a key component of improving VMware’s support mechanisms.
  • Dell leads off the discussion on a question regarding quantum computing, artificial intelligence (AI) and machine learning (ML), and other forward-looking efforts. Naturally, he positions his company (Dell Continue reading

My Career Planning: A Ride-Along

About a year ago I shared with you (Thinking Out Loud: My Career Planning) a little about my yearly career planning process.  This time I’m going to bring you on a ride-along of this year’s annual Career Planning exercise.

First and foremost I must answer a common question that I was asked a lot after last year’s blog.

The Dream Job Question: 

“Why do you even bother with the yearly career planning process? You are always saying that CPOC is your dream job come true”

Yes. Without a doubt CPOC really is my absolute dream job come true!  I consider myself so truly fortunate, blessed and lucky to still be here with CPOC.  Rocking 16 1/2 years with CPOC and the CPOC family at Cisco!

So that all being said… why do I still review every year?  Like I mentioned in last year’s blog “over the years what I’ve seen is that my 1 year plan, 3 year plan, 5 year plan and 10 year plans have changed as I have changed.”  So then reviewing every year is just taking the time to “check in” that the job I’m in is not Continue reading

Introducing VMware AppDefense – Expanding beyond micro-segmentation to threat detection and response

Hopefully, you have heard the news today! We couldn’t be more excited to announce the general availability of VMware AppDefense, our new security solution. AppDefense bolsters the micro-segmentations threat prevention capabilities delivered by NSX with data center endpoint threat detection and response. It’s no secret that organizations are spending more money than ever on security. It’s also no surprise that the only thing outpacing security spend are the losses due to security breaches. At VMware, we believe the struggle organizations face in gaining the upper-hand in this battle is due to a foundational architectural gap that creates misalignment between the infrastructure where security is applied and the applications that security is designed to protect.

NSX was the first step toward re-aligning network security policy with applications by leveraging the virtualization layer to enable micro-segmentation, as well as enhance the posture of other security solutions through integrations and features like service insertion and guest introspection. But applications are made up of both networks and data center endpoints like VMs. AppDefense is the other half of the puzzle. Whereas NSX prevents threats from moving freely throughout the network, AppDefense detects anything that does make it to an endpoint and can automatically Continue reading
