When Diverse Network ASICs Meet A Unifying Operating System

And it has also been a decade since switch upstart Arista Networks launched its Extensible Operating System, or EOS, which is derived from Linux. [...] The cross-platform nature of ArcOS, coupled with its ability to run in any function on the network, could turn out to be the key differentiator. A lot of these other NOSes were point solutions that could only be deployed in certain parts of the network, and that just creates animosity with the incumbent vendors that dominate the rest of the networking stack. Given the mission-critical nature of networking in the modern datacenter, it costs a great deal to qualify a new network operating system, and it can take a lot of time. If ArcOS can run across more platforms, qualify faster, and do more jobs in the network, then, says Garg, it has a good chance of shaking up switching and routing. “That totally changes the business conversation and the TCO advantages that we can bring to a customer across the entirety of their network.” Read more

  • Improving trust in the cloud with OpenStack and AMD SEV

    This post contains an exciting announcement, but first I need to provide some context! Ever heard that joke “the cloud is just someone else’s computer”? Of course it’s a gross over-simplification, but there’s more than a grain of truth in it.
