I am fortunate enough, to be able to goto Cisco Live US! again this year.
Last year was such an experience, that my hopes are really high for this year as well.
I will be arriving on Friday the 8th and leaving on the 15th. Not a long stay this time, but it was what my boss could arrange for.
Again this year I will be bringing my better half, so she can experience the city and hopefully we’ll get a few hours of sightseeing in between commitments.
One of the things that im really looking forward to, is meeting up with friends and peers. This year is a bonus for me, as I get to say Congratulations to my friend Daniel (lostintransit.se) in person and not just on the phone, on passing the CCDE practical exam!
Also, a first for me, will be meeting up with Darren (mellowd.co.uk). We have been talking for a long time on twitter, mail and webex and im really looking forward to meeting him in person.
When we get closer to the event, I will be posting my Cisco Live! schedule here.
If you happen to be Continue reading
Containers are popular for many reasons. One key reason: container images are easy to build and, once built, don't change. When Developer A says, "Hey, check out this new application, just download this container image and run it," Developer B doesn't have to ask the question, "How do I configure it?" Developer B can just download the image and run the container, and enjoy a high likelihood that it will run exactly as Developer A intended.
Until Developer A announces the need for a second, third and fourth container, that is. A microservices approach advocates for simple containers, sure -- but that also means more of them, all doing different things, and all connecting together... somehow. So now Developer A needs to tell Developer B "be sure to run all of these containers together, and make sure these two containers share a data volume, and make sure these other two containers have a network link between them, and make sure the REST API for this one is exposed on these ports. Oh, also! Make sure you've got your DNS set up right, because it's all a hilarious dumpster fire if you don't."
Complexity doesn't go away in the container world; it just moves to different Continue reading
We have officially reached the point in our long and storied IT careers where we, as old fogies, have earned the right to complain about the next generation of users and professionals. Just as the gray beards before us complained about the way we did things, so too is it our turn to moan about the state of affairs. Today, I’d like to point out how driving IT to the point of pushing simple buttons is destroying the way we do things.
The fact that IT work has been able to be distilled into a series of simple button pushing exercises is very thrilling. We’ve spent a lot of time and effort building devices and frameworks that take the hard part out of building devices and frameworks. We no longer have to invent languages to build things or hardware to do things. Instead, we can refine our programming capabilities or use general purpose hardware in new combinations to provide environments for our users.
That’s one of the things that is driving people to the cloud. Cloud isn’t just about exciting hardware or keeping your data in other places. It is just as much about predictable, repeatable frameworks and Continue reading

One of my CCDE bootcamp students asked a question about next hop in MPLS VPN network. So, I would be very pleased to explain the BGP next hop behaviour both in IP and MPLS network in this post. Let’s start with this IP network shown below (Figure-1). Figure-1 IBGP Next Hop handling in IP networks In […]
