Converged Vs. Hyperconverged Infrastructure: What’s The Difference?
Both provide an alternative to traditional IT infrastructure integration, but take different approaches.

I appreciated this rant by @alicegoldfuss on a impractical parts of running containers. Not many people talk about the downsides.
(shame its not on a blog somewhere where it would be readable)
It's almost like containers only improved the Dev side of DevOps hmmmm how strange

Hope none of your containers have noisy neighbors because cgroups only go so far.

Iptables? Different with containers? Perf profiling? Much harder with containers.

Orchestrators can redeploy a dead instance but can they detect latency and move it to a better system? Because a slow container is hell.

Everyone using containers means I don't have to wake someone else up to deploy their broken shit. It makes DR much faster, too.

But that's only half of the ol DevOps pie. The other half? More burden and work. At scale.

In my initial OSPF Forwarding Address blog post I described a common Forwarding Address (FA) use case (at least as preached on the Internet): two ASBRs connected to a single external subnet with route redistributing configured only on one of them.
That design is clearly broken from the reliability perspective, but are there other designs where OSPF FA might make sense?

On September 30, 2016, the contract between the U.S. government and the Internet Corporation for Assigned Names and Numbers (ICANN) over the Internet Assigned Numbers Authority (IANA) ended. This marked a process of almost 20 years that started with the privatization of the Domain Name System (DNS) in 1998. With the contract expired, taking stock of the process becomes critical. What unfolded for more two years was not just about the transition of a set of functions, critical to the operation of the Internet: it was also about the ability of the Internet community to stay true to the practices that have historically made the Internet evolve and work better.
That makes $110 total raised for defending endpoints and servers.
This post was written to help CCDE candidates get into the right mindset but is very applicable to network architects and network engineers in general.
We humans tend to have a lot of bias. Sometimes it’s based on experience but often it’s based on how pure a technology is or a bad implementation of a protocol. Often we don’t reevaluate our opinion so if we had a STP incident in the past, STP becomes inherently bad for all future.
Preparing for the CCDE from a technology standpoint is relatively easy compared to getting into the right mindset and getting enough exposure to network designs. Don’t get me wrong, it’s a technically difficult exam but the number of candidates taking the exam that have the right knowledge level of technology are far higher than the number of people actually passing the exam. I have seen this time and time again.
Because we have this bias we immediately base our feeling and design based on our feelings or previous experience without taking the business requirements and technical constraints into consideration.Yes, maybe MPLS was the best answer to the question from a technical standpoint but maybe there was a constraint that only Continue reading
