I am often humbled by the depth of insight of those who toil in the trenches
of the enterprise data center.
At our Agility conference back in August, my cohort and I gave a presentation
on the State of Application Delivery. One of the interesting tidbits of data
we offered was that, over the course of the past year, our iHealth data shows
a steady and nearly even split of HTTP and HTTPS traffic. To give you an
example, my data from October was derived from over 3 million (3, 087, 211 to
be precise) virtual servers. Of those, roughly 32% were configured to support
HTTP, and another 30% were supporting HTTPS.
Now, I’ve been looking at this data for more than a year, and it has stayed
roughly the same with only slight variations up or down, but always within a
couple percentage points of each other. But it wasn’t until a particularly
astute customer spoke up that I und... (more)
Microservices versus Microsegmentation
Let's just nip the conflation of these terms in the bud, shall we?
"MIcro" is big these days. Both microservices and microsegmentation are
having and will continue to have an impact on data center architecture, but
not necessarily for the same reasons. There's a growing trend in which folks
- particularly those with a network background - conflate the two and use
them to mean the same thing.
They are not.
One is about the application. The other, the network. There is a
relationship, but it's a voluntary one. They are two very different thing... (more)
In case you haven’t heard, the new hotness in app architectures is
serverless. Mainly restricted to cloud environments (Amazon Lambda, Google
Cloud Functions, Microsoft Azure Functions) the general concept is that you
don’t have to worry about anything but the small snippets of code
(functions) you write to do something when something happens. That’s an
event-driven model, by the way, that should be very familiar to anyone who
has taken advantage of a programmable proxy to do app or API routing and
rewriting or executed inspection of requests or responses for malicious
Yes, Lori has been reading the Internet again. And what she's been seeing
makes baby Lori angry. It also makes this former test designer and technology
editor cry. Really, I weep at both the excuses offered for such testing and
the misleading headline.
I have read no less than two contrived comparisons of "HTTPS" and "HTTP" in
the last two weeks purporting to demonstrate that secure HTTP is inarguably
faster than its plaintext counterpart, HTTP.
Oh, if only that were true.
See, the trick is that both comparisons (and no doubt many more will follow)
are comparing secure HTTP/2 wi... (more)
Momentum behind OpenStack continues to accelerate as the releases for the
often touted open source cloud management framework mature and stabilize.
Some of that momentum comes from early adopters who've put the system through
its paces in real enterprise and web-scale environments.
RedHat, certainly one of the heavyweights in the industry current all in for
OpenStack, offered up survey results indicating that 84% of the 200 US
enterprise decision makers were planning on OpenStack being part of their
future private cloud plans. Given that the same survey conclude... (more)
