Microservice architectures are the new hotness, even though they aren't
really all that different (in principle) from the paradigm described by SOA
(which is dead, or not dead, depending on whom you ask).
One of the things this decompositional approach to application architecture
does is encourage developers and operations (some might even say DevOps) to
re-evaluate scaling strategies. In particular, the notion is forwarded that
an application should be built to scale and then infrastructure should assist
It was just this notion that led me to a discussion on a particularly useful
explanation of scaling strategies called "the scale cube" which is introduced
and explained further in The Art of Scalability. Go ahead and open it up and
bookmark it; it's a good read and I highly recommend it.
The aforementioned discussion provides an overview of the thre... (more)
How SDAS Are Delivered - as a Service
Organizations are turning to cloud not just as an option for applications but
also for the network and application services that deliver applications to
anyone, anywhere at any time. And not just "in" the cloud marketplace,
available for immediate provisioning and deployment, but as part of the cloud
itself; as a service.
One of the questions we asked of respondents in our survey this summer
focused on the preferred deployment model across the breadth of application
services. Security, I'm sure unsurprisingly, wound up with a significant
Applications are as integral to F5 technologies as they are to your business.
An old adage holds that an individual can be judged by the company he keeps.
If that holds true for organizations, then F5 would do well to be judged by
the vast array of individual contributors, partners, and customers in its
ecosystem. From its long history of partnering with companies like Microsoft,
IBM, HP, Dell, VMware, Oracle, and SAP to its astounding community of over
160, 000 engineers, administrators and developers speaks volumes about its
commitment to and ability to develop joint and custom ... (more)

When we talk about the impact of BYOD and BYOA and the Internet of Things, we
often focus on the impact on data center architectures. That's because there
will be an increasing need for authentication, for access control, for
security, for application delivery as the number of potential endpoints
(clients, devices, things) increases. That means scale in the data center.
What we gloss over, what we skip, is that before any of these "things" ever
makes a request to access an application it had to execute a DNS query.
Every. Single. Thing.
Maybe that's ... (more)
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 deploy and manage operations than it is some c... (more)
