Cloud and Things and Big Operational Data
Software-defined architectures are critical for achieving the right mix of
efficiency and scale needed to meet the challenges that will come with the
Internet of Things
If you've been living under a rock (or rack in the data center) you might not
have noticed the explosive growth of technologies and architectures designed
to address emerging challenges with scaling data centers. Whether considering
the operational aspects (devops) or technical components (SDN, SDDC, Cloud),
software-defined architectures are the future enabler of business, fueled by
the increasing demand for applications.
The Internet of Things is only going to make that even more challenging as
businesses turn to new business models and services fueled by a converging
digital-physical world. Applications, whether focused on licensing,
provisioning, managin... (more)
Just What Does 'Operationalize' Mean Anyway?
Operationalization (which is really hard to say, go ahead - try it a few
times) is a concept that crosses the lines between trends and technologies.
Both SDN and DevOps share the notion of "operationalization" as a means to
achieve the goal of aligning IT with business priorities, like that of
accelerating time to market for all important applications.
But what does it really mean to operationalize the network, or app
deployments, or really, anything?
Operationalization is a lot like DevOps in that it's more of an approach to
how you ... (more)
What DevOps Can Do About Cloud's Predictable Provisioning Problem
Go ahead. Name a cloud environment that doesn't include load balancing as the
key enabler of elastic scalability. I've got coffee... so it's good, take
Exactly. Load balancing - whether implemented as traditional high
availability pairs or clustering - provides the means by which applications
(and infrastructure, in many cases) scale horizontally. It is load balancing
that is at the heart of elastic scalability models, and that provides a means
to ensure availability and even improve performance of app... (more)
Kirk Byers at SDN Central writes frequently on the topic of DevOps as it
relates (and applies) to the network and recently introduced a list of seven
DevOps principles that are applicable in an article entitled, "DevOps and the
Chaos Monkey. " On this list is the notion of reducing variation.
This caught my eye because reducing variation is a key goal of Six Sigma and
in fact its entire formula is based on measuring the impact of variation in
results. The thought is that by measuring deviation from a desired outcome,
you can immediately recognize whether changes to a process impro... (more)
Shellshock, appropriately and of course punnily named, is ravaging the
Internet right now. Active exploits continue to grow in number and in
While there are multiple avenues through which this vulnerability can be
exploited, the most active one at the moment appears to be via vulnerable
Internet-facing systems running web applications.

These attacks take advantage of the lax constraints on HTTP headers that
allow strings of nearly limitless length to be passed not just to the web
server, but on to the system via ... (more)
