DevOps Summit: Where the Network Got Invited to the Party At DevOps Summit NY there's been a whole lot of talk about not just DevOps, but containers, IoT, and microservices. Sessions focused not just on the cultural shift needed to grow at scale with a DevOps approach, but also made sure to include the network "plumbing" needed to ensure success as applications decompose into the microservice architectures enabling rapid growth and support for the Internet of (Every)Things. Containers and Microservices and the Network Jerome Petazzo (@jpetazzo) of Docker discussed microservices and their natural affinity for containers, but significant in his discussion was the need for "the network" for independent scale, discovery, resiliency, and managing the increasingly network-dependent architecture resulting from microservices. Indeed, DNS plays a natural and important role in ... (more)

Measuring and Monitoring: Apps and Stacks By @LMacVittie | @DevOpsSummit #DevOps #Microservices

One of the charter responsibilities of DevOps (because it's a charter responsibility of ops) is measuring and monitoring applications once they're in production. That means both performance and availability. Which means a lot more than folks might initially think because generally speaking what you measure and monitor is a bit different depending on whether you're looking at performance or availability*. There are four primary variables you want to monitor and measure in order to have the operational data necessary to make any adjustments necessary to maintain performance and av... (more)

What Ops Needs to Know about HTTP/2 | @DevOpsSummit [#DevOps]

What Ops Needs to Know about HTTP/2 So HTTP/2 is official. That means all the talking is (finally) done and after 16 years of waiting, we've got ourselves a new lingua franca of the web. Okay, maybe that's pushing it, but we do have a new standard to move to that offers some improvements in the areas of resource management and performance that make it definitely worth taking a look at. For example, HTTP/2 is largely based on SPDY (that's Google's SPDY, for those who might have been heads down in the data center since 2009 and missed its introduction) which has proven, in the field...

The Art of Scale with Microservices | @DevOpsSummit [#DevOps]

The Art of Scale: Microservices, The Scale Cube and Load Balancing 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 ne... (more)

Microservices and HTTP/2 By @LMacVittie | @DevOpsSummit #DevOps #Docker #Containers #Microservices

Microservices & IoT Power Panel at @DevOpsSummit In this Power Panel at @DevOpsSummit, moderated by Jason Bloomberg, president of Intellyx, panelists Roberto Medrano, Executive Vice President at Akana; Lori MacVittie, Evangelist for F5 Networks; and Troy Topnik, ActiveState's Technical Product Manager; and Otis Gospodnetić, founder of Sematext; peeled away the buzz and discuss the important architectural principles behind implementing IoT solutions for the enterprise. As remote IoT devices and sensors become increasingly intelligent, they become part of our distributed cloud en... (more)
