Fad? No, containers are here to stay

Dig into the the red-hot open source framework in InfoWorld's beginner's guide to Docker. At a high level, they provide lightweight platform abstraction, without using virtualization. They're also much more efficient for creating workload bundles that are transportable from cloud to cloud. In many cases, virtualization is too cumbersome for workload migration.

Want to fix Seattle traffic? Redditor makes game that allows players to tweak city streets and more


Dustin Carlino released the alpha version of A/B Street on Monday, complete with a trailer on YouTube (above), writing in a post on Reddit that he has spent the past two years working on the open source computer game. That sparked an enduring interest in transportation infrastructure.

This blog post kicks off a new series of posts describing my journey to become more knowledgeable about the Nicira Network Virtualization Platform (NVP). Southbound communications protocols: NVP uses two open communications protocols to communicate southbound to OVS.

IDS/IPS – Intrusion detection system, Intrusion prevention system Tools


Source: Wikipedia. An IPS can also correct Cyclic Redundancy Check (CRC) errors, unfragment packet streams, prevent TCP sequencing issues, and clean up unwanted transport and network layer options. Source: Wikipedia. Layer 2, Peer-to-peer VPN (Virtual Private Networks).

As opposed to just encrypting data at the transport level (although Acra does that between components of its architecture) or just encrypting data at the storage level (using an encrypted file system or similar), Acra targets encrypting data at the table/row/column level within a database. Acra is open source and available via GitHub. Here’s a post outlining some of VMware’s more prominent open source projects in the “cloud-native” space. Virtualization.

Learning NVP, Part 4: Adding Hypervisors to NVP

Scott Lowe

To get a version of libvirt that supports Open vSwitch (OVS) , you’ll want to enable the Ubuntu Cloud Archive. Create a Transport Zone. Before you can actually add the hypervisor to NVP, you first need to ensure that you have a transport zone defined.

A fan of network virtualization might also say that decomposing today’s complex physical networks into multiple simple logical networks on top of a simpler physical transport network—similar to Mike’s suggestion of converging on a smaller set of reference architectures—might also help. (Of Of course, I am a fan of network virtualization, since I work with/on VMware NSX.). Here’s a good source. Virtualization.

To help resolve this issue, Cumulus Networks (and possibly Metacloud, I’m not sure of their involvement yet) has release an open source project called vxfld. One ongoing discussion in the network industry these days—or so it seems—is the discussion about the interaction between network overlays and the underlying transport network. SDN Central has a nice write-up on the need for open efforts in the policy space, which includes the Congress project.

with the Floodlight open source controller. It’s not at all unreasonable to think that you might have a fabric controller that is responsible for managing/optimizing traffic flows across the physical transport network/fabric, and an overlay controller—like VMware NSX—that integrates tightly with the hypervisor(s) and workloads running on those hypervisors to create and manage logical connectivity and logical network services.

In a world of digital connections, customers take for granted virtually immediate responses to their problems and desires. Chat and discussion forums are the new agoras—public, open spaces in which everyone can hear what others are saying and join in with their own thoughts.

Managing Open vSwitch with Puppet

Scott Lowe

In this post, I’m going to show you how to manage Open vSwitch (OVS) using the popular open source configuration management tool Puppet. You could then assign the newly-created tep0 interface an IP address on your transport network like this: l23network::l3::ifconfig {''tep0'': ipaddr => ''''}.
