As IT organizations move to embrace containers, many are revisiting the entire stack on which their IT services are delivered. After all, relying on legacy IT infrastructure to deliver modern applications seems counterintuitive. In place of that legacy infrastructure, IT organizations are looking at embracing everything from lighter-weight implementations of Linux such as Tectonic from CoreOS to virtual networks such as the open source Project Calico initiative.
With the arrival of version 1.1 of the Kubernetes orchestration framework, Project Calico can now be integrated with CoreOS alongside existing support for OpenStack and Mesosphere management. Sponsored by Metaswitch, Project Calico implements a virtual router in each compute node in a way that eliminates the need to rely on a virtual switch. Each vRouter propagates workload reachability information, also known as routes, to the rest of the data center using the Border Gateway Protocol (BGP).https://o1.qnsr.com/log/p.gif?;n=203;c=204663295;s=11915;x=7936;f=201904081034270;u=j;z=TIMESTAMP;a=20410779;e=iAndy Randall, lead evangelist for Project Calico and senior vice president and general manager for Metaswitch, says the end goal is to significantly reduce the amount of physical infrastructure required to provide networking services in a world where commodity compute capacity in the form of industry standard x86 servers is readily available.
Going into 2016, it’s pretty clear that IT organizations are going to have to start thinking a lot more about how IT services are made available. The history of computing thus far assumes that compute, storage and networking all need to run in isolation on their own physical infrastructure. But with the rise of x86 servers that come with more processing cores than most organizations know what to do with, there is at least an opportunity to collapse the physical IT infrastructure required to support distributed computing applications running at scale in the age of the cloud.
Naturally, the process is not going to take place over night. Substantial technical and cultural IT issues will need to be addressed. But as is often the case when it comes to enterprise IT, the most significant changes are the ones that take several years to play out before everybody starts to recognize just how profound they really are.
