Security groups (or Endpoint Groups if you’re a Cisco ACI fan) are a nice traffic policy abstraction: instead of dealing with subnets and ACLs, define groups of hosts and the rules of traffic control between them… and let the orchestration system deal with IP addresses and TCP/UDP port numbers.

Well, if you are, feel free to reach out - I would love to have a conversation out in San Diego! I just booked a trip to Cisco LIVE, but am only purchasing the $49 DevNet Explorer pass. This means I should have plenty of time to socialize and will likely be spending most of my time at the DevNet zone. I’ll have access to my remote lab and should be able to demo much of what I’ve posted about in the past few months too.
Email me (jedelman8 at gmail) or comment below if you’re interested in meeting up.
Thanks,

Google Cloud and AWS have been waging a price war for a while, but Google is the latest to shoot.
OpenStack Summit kicks off in Vancouver.
SDx applications have new needs from next-gen IT infrastructure that go beyond old models and architectures. Find out what they and stake your claim in the SDx world.
Kilo is the eleventh major OpenStack release, with enhancements across the board and new features like Ironic for bare metal service provisioning. SMB to large-scale clouds with OpenStack are being deployed in droves with a self-service portal to spin up virtual and now bare metal workloads while automatically provisioning all the requisite compute, storage and networking resources. Yet, network service provisioning remains to be cumbersome, brittle and closed.
OpenStack and Cumulus Linux share a common philosophy, design and operational framework. Compute and storage (with Cinder and Swift) leverage standard infrastructure, so why use black boxes from Cisco and Arista, especially when the systems are merchant silicon reference designs. Cumulus Linux is unencumbered Linux without proprietary APIs and protocols, with the flexibility to run on your platform of choice. Build and runtime operations are identical from bootstrapping infrastructure with PXE or ONIE to lifecycle management with config management and patching. Clouds have become the new frontier not only for orchestration platforms like OpenStack but for tools, processes and organizations. Converged administration with battle-tested automation platforms (such as Puppet, Chef or Ansible) or monitoring (with Nagios or collectd) enable admins to rise to critical tasks such Continue reading
