Docker spouts cash, sucks up Tutum
Docker has hoovered up container hosting outfit Tutum, creating what the cash-packed buyer claims will be a complete platform to build, ship and run distributed applications.
Both companies are privately held, and financial terms were not disclosed. It seems safe to assume the deal will add nothing to Docker’s bottom line or indeed its top line, for now.
Tutum’s pricing page claims the service is “limitless” and free while it is still in beta, with a professional service promised sometime in the future.

Tutum Buyout Gives Docker Inc. Container Deployment Prowess

DevOps case study: Rabobank cuts deployment by 60 percent
A company’s capacity to keep customers happy, capture new markets or engage business in new ways is often dependent on its IT department’s ability to create and release software. Yet the pace of releasing this software is no longer an annual or semi-annual event, but rather a continuous flow of new iterations and adjustments to meet market needs as they evolve and change. DevOps is breaking down the barriers between departments. Continuous delivery is providing an end-to-end framework that can help IT teams deliver software in an automated fashion.

OpenStack Security Groups using OVN ACLs
It’s worth looking at how this has been implemented with OVS in the past for OpenStack. OpenStack’s existing OVS integration (ML2+OVS) makes use of iptables to implement security groups. Unfortunately, to make that work, we have to connect the VM to a tap device, put that on a linux bridge, and then connect the linux bridge to the OVS bridge using a veth pair so that we have a place to implement the iptables rules. It’s great that this works, but the extra layers are not ideal.

OpenStack Addresses Network Orchestration Layer
While the OpenStack community likes to present a unified front to the outside world, inside the various projects that make up the OpenStack framework, there is a lot of frustration with the Neutron networking component of OpenStack. Much of that frustration stems from the fact that after five years of effort Neutron still doesn't scale particularly well. As such, many of the organizations that have embraced OpenStack wind up swapping in a commercial network layer of software to replace Neutron.

Exposing the Truth About OpenStack Cloud Deployments
Lured by the siren song of better business agility and accelerated innovation, an increasing number of companies are considering or have already deployed private clouds as part of their IT strategy. Since emerging in 2010 as an open-source initiative to help organizations build cloud services on industry-standard hardware, OpenStack has garnered much attention, but its adoption in production environments has been tempered by an assortment of perceived limitations, both real and imagined.
