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 where necessary. 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)

SDAS Are Going Hybrid By @LMacVittie | @DevOpsSummit [#DevOps]

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 nu... (more)

F5 Friday: Applications Aren't Protocols, They're Opportunities

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 ...

The Internet of Things and DNS

JANUARY 8, 2014 02:00 PM EST 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)

Just What Does 'Operationalize' Mean Anyway? By @LMacVittie [#DevOps]

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)
