Networking Containers: Policy Finally Comes of Age

by Mike Cohen

Few question that Linux containers signal a tectonic shift in how applications are built, deployed, and operated and their composition into microservices will likely become a best practice in application design.(1)  This shift could mean a lot for us in the networking space.  We’ll see a faster migration to 40G or 25/50/100G architectures, a serious focus on scale as we could see up to a million MAC/IPs coming to a single ToR, and a push for improved visibility and telemetry as the network becomes the unifying measurement point between separate micro services.(2) But potentially most important will be the shift towards using higher level, application oriented policies to capture user intent, a change that could revolutionize automated network configuration.   (more…)

As the hardware era ends and the software-defined world progresses, the over $400B worldwide compute, storage, and networking market and vendors like Dell, Cisco, IBM, HP, and many others that supply it are struggling with the change. Legacy vendors are disappearing or restructuring, as evidenced by the HP breakup and Dell’s purchase of EMC and VMware. But unlike an artist painting a masterpiece, this technology transformation is not controlled by any one person, company, or institution, making it a leveler, offering advantage to only those that embrace it. There is no army large or strong enough to stop this progression as it fundamentally reshapes the IT landscape. While the shift from hardware to software sounds simple and perhaps trivial, its implications are anything but. (more…)
