The Importance of Licensing to Equalize Dev and Production We’re all aware that dev/test != production environments. While the software stacks upon which applications are deployed may be (and hopefully are) the same, there still remains a whole lot of “infrastructure” (that’s everything else) that isn’t the same. Routers, switches, security devices, load balancers, caches, and other devices dedicated to ensuring the secure delivery of applications to hungry consumer and corporate users simply don’t exist in the dev/test environment. That’s particularly true as organizations continue to view “the cloud” as its ideal dev/test environment while continuing to insist that production remain firmly rooted on-premises. The State of the Developer Nation Q3 2015 from VisionMobile noted this phenomenon: Almost half of developers are hosting their apps in private clouds, well... (more)

A Simple Trick For Faster Apps | @DevOpsSummit #APM #DevOps #AI #ML

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 anot... (more)

The #IoT and DNS | @ThingsExpo #BigData #IoT #M2M #DigitalTransformation

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)

APIs Are Not Web Pages | @DevOpsSummit #API #IoT #M2M #DNS #DevOps

There’s a tendency, particularly for networkers, to classify applications by the protocols they use. If it uses HTTP, it must be a web app. The thing is that HTTP has become what it was intended to be: a transport protocol. It is not an application protocol, in the sense that it defines application messages and states. It merely transports data in a very specific way. That’s particularly important in the age of the API and, increasingly, the age of things that might be using APIs. You see, APIs are primarily data centric constructs while web pages (think any HTML-based app) are do... (more)

Microsegmentation or #Microservices | @DevOpsSummit #DevOps #IoT #Docker

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)
