A few months ago at Cloudflare’s Internet Summit, we hosted a discussion on A Cloud Without Handcuffs with Joe Beda, one of the creators of Kubernetes, and Brandon Phillips, the co-founder of CoreOS. The conversation touched on multiple areas, but it’s clear that more and more companies are recognizing the need to have some strategy around hosting their applications on multiple cloud providers.
Earlier this year, Mary Meeker published her annual Internet Trends report which revealed that 22% of respondents viewed Cloud Vendor Lock-In as a top 3 concern, up from just 7% in 2012. This is in contrast to previous top concerns, Data Security and Cost & Savings, both of which dropped amongst those surveyed.
At Cloudflare, our mission is to help build a better internet. To fulfill this mission, our customers need to have consistent access to the best technology and services, over time. This is especially the case with respect to storage and compute providers. This means not becoming locked-in to any single provider and taking advantage of multiple cloud computing vendors (such as Amazon Web Services or Google Cloud Platform) for the same end user services.

HPE acquired the technology from Nimble Storage, which it bought for $1 billion earlier this year.
Public cloud has its pros and cons, but enterprises today can't afford to be anti-cloud.
Got this feedback on my Ansible for Networking Engineers webinar:
This webinar is very comprehensive compared to any other Ansible webinars available out there. Ivan does great job of mapping and using real life example which is directly related to daily tasks.
The Ansible online course is even better: it includes support, additional hands-on exercises, sample playbooks, case studies, and lab instructions.
However, Ansible is just a tool that shouldn’t be missing from your toolbox. If you need a bigger picture, consider the Building Network Automation Solutions online course (and register ASAP to save $700 with the Enthusiast ticket).
As part of my “everything should be on a UPS” strategy, I recently replaced a regular 8-port gigabit switch with a Ubiquiti Unifi US-8 Ethernet switch because the US-8 can be powered using POE (Power Over Ethernet) provided by a UPS-protected switch in my basement, so it should stay up in the event of a power outage. This also allowed me to indirectly provide UPS protection for the Ubiquiti wireless AP in that location because the US-8 has a PoE passthrough port with which I could power the AP. Clever, right?
To clarify (because a picture is worth many thousands of my words), here’s how things were:
And here’s how things are after installing the Ubiquiti Unifi US-8:
The new setup worked well, but I noticed after a few days that the uptime for the Unifi US-8 kept on resetting; that is, it appeared to be rebooting. The Cisco 3560CX switch which is providing the POE can supply 30W per port, which is plenty enough for the US-8 and the wireless AP to be daisy-chained like this, yet when I looked at the logs on the 3560CX, I found an error:

The other day Daniel Dib (http://lostintransit.se) asked me an interview question. The question was about certifications. What do I think about them…. and are they losing their “value”.
Poor certifications. People question their value. Of course “value” typically means for many what can the cert “do” for you once you have it. People also get so judgemental of others for “collecting” them. And yes… when I was younger I was, admittedly, one of those people who looked down on people I viewed as “cert collectors”. Poor poor certifications. In every area certifications exist they can get a bad rep. IT industry, Scuba Diving, .. heck even in girl scouts when there was always that one girl who wanted to try to get every possible girl scout badge.
In 2012 my view on certs changed. I realized I could use them to my advantage to help me organize my learning by making goals and signing up for certs. You see, back in 2010 I had bought a few books about Wireshark by Laura Chappel and told myself I would make Continue reading
