In the currently high-flying world of DevOps, automation is the king. We are
"automating all of the things" at a pretty astounding rate, and it is
increasing productivity by reducing the man-hours invested in repetitive
work. All very cool, but there is a dark side to automation, and that's
control. While automating the entire datacenter is very cool, immature
products sometimes lack the ability to let operators step in and approve
changes before rolling them out.
Traditionally, the "review and approve" step is part and parcel of
automation. New "just do it" tools are normally equipped with a review step
to increase their appeal to datacenter teams during the verification and
acceptance phase of rollout.
But DevOps got ahead of itself, and some vendors, wanting to move faster than
competitors, started building their tools to take action by default, and not
Because of the explosive growth of DevOps, there is still a seemingly large
amount of confusion on the topic. While I’ve written about this before
[link to DevOps article], this article takes a shot at dividing things in a
way that we naturally do as users, but vendors often fail to differentiate,
simply because “DevOps” is a hot term, and it’s all too often about SEO
and AdWords when vendors talk/write.
Dev? Or Ops?
DevOps has two different sources – Development that is getting Ops added in
– like automated test, integration, etc., and Ops that is getting
Development added in –... (more)
If Hardware is Commodity... Why Are We Still Spending so Much Time on It?
We really are moving in the direction of truly commoditized hardware. Some
uses will always have specific requirements that are not mainstream and thus
will require specialized builds; this is true in every industry. But
increasingly, who made your hardware and where they got their parts from is a
Which makes one consider what really sells hardware these days. Years ago
when I was working for Network Computing, I reviewed a low-end blade server
company capable of cranking up blades at a fra... (more)
The Cloud Is in a Datacenter
Funny thing about the never-ending discussions of cloud, virtualization, and
containers out here in pundit-land… Most writers blithely ignore the one
truth that all of us need to be reminded of on occasion.
Your cloud is built on hardware.
Yes indeed, I did say that out loud. Talk about fifteen layers of
server/network virtualization all you like, SDX your way into the 22nd
century, but never forget that someone somewhere is racking and stacking to
make it happen.
Why does that matter? Well for a lot of reasons, though they can be broken
into the us... (more)
Teaching young children about electronics is difficult. If you are a parent
that isn't knowledgeable about electronic circuits, you feel like you have to
study before teaching, and if you are a parent that is knowledgeable about
circuits, you have to try and balance all that you know against holding the
child's interest. This balance is all too often broken by a parent wanting to
impart the very important information like how to read the bands on a
resistor, while the child wants to just do it.
If you read my blog regularly, you know that it is rare for me to plug a
company's pr... (more)
