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 un... (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)

Serverless Security | @DevOpsSummit #DevOps #LowCode #Serverless

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 content....

Ops, APIs and Compression | @DevOpsSummit #API #APM #DevOps

I've been reading up on APIs cause, coolness. And in particular I really enjoyed reading Best Practices for Designing a Pragmatic RESTful API because it had a lot of really good information and advice. And then I got to the part about compressing your APIs. Before we go too far let me first say I'm not saying you shouldn't compress your API or app responses. You probably should. What I am saying is that where you compress data and when are important considerations. That's because generally speaking no one has put their web server (which is ultimately what tends to serve up respons... (more)

Microservices and HTTP/2 | @DevOpsSummit #DevOps #Microservices

It's all about that architecture. There's a lot of things we do to improve the performance of web and mobile applications.  We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure. The recently official HTTP/2 specification takes performance very... (more)
