It is fairly common to hear about switch being non-blocking. It’s because almost all switches today are non-blocking. But what that means? When I asked people around me on what exactly non-blocking switch means, they were unable to get to the same conclusion. I was going through a lot of different internet places and vendor documents before I wrote this here, but, do not hesitate to add something in comments if you have different view on the subject. Line-rate switch means the same as if you would said wire-speed switch. It basically means that this switch has the forwarding capacity that supports concurrently
Citizens of Tech is an experimental podcast about technology and other things interesting to techies. We know there's other podcasts in this space, but it's something we really wanted to do, so we thought we'd give it a try.

Today the Magento Security Team created a new ModSecurity rule and added it to our WAF rules to mitigate an important RCE (remote code execution) vulnerability in the Magento web e-commerce platform. Any customer using the WAF needs to click the ON button next to the “CloudFlare Magento” Group in the WAF Settings to enable protection immediately.
Both Magento version 1.9.1.0 CE and 1.14.1.0 EE are compromised by this vulnerability. CloudFlare WAF protection can help mitigate vulnerabilities like this, but it is vital that Magento users patch Magento immediately. Select and download the patch for SUPEE-5344.
What would it take to watch every frickin' packet on the network?
By now you’ve probably seen or heard the news about Ravello Systems launching Inception—the ability to run nested VMware ESXi on AWS or GCE, including the ability to run VMs on these nested ESXi instances. (Here’s Ravello’s press release.)
In my opinion, this is pretty cool, and it opens the door to a lot of different possibilities: upgrade testing, automation testing, new feature testing, hosted home labs (aka “Lab as a Service”). Lots of folks are interested in using this new Ravello functionality for “Lab as a Service.” Here’s Andrea Mauro’s take on this topic.
As part of the pre-launch activities, a number of bloggers and community advocates were able to work with Ravello on some very interesting projects:
I was also engaged with Ravello on a project: building a (reasonably) large-scale vSphere environment on Ravello. The original goal was to Continue reading

I’ve been working over the last couple of weeks in integrating OpenContrail as a networking implementation for Kubernetes and got to the point where i ‘ve a prototype working with a multi-tier application example.
Kubernetes provides 3 basic constructs used in deploying applications:
A Pod is a container environment that can execute one or more applications; each Pod executes on a host as one (typically) or more Docker processes sharing the same environment (including networking). A Replication Controller (RC) is a collection of Pods with the same execution characteristics. RCs ensure that the specified number of replicas are executing for a given Pod template.
Services are collections of Pods that are consumable as a service. Through a single IP end point, typically load-balanced to multiple backends.
Kubernetes comes with several application deployment examples. For the purpose of prototyping, I decided to use the K8PetStore example. It creates a 4-tier example: load-generator, frontend, redis-master and redis-slave. Each of these tiers, except for the redis-master) can be deployed as multiple instances.
With OpenContrail, we decided to create a new daemon that listens to the kubernetes API using the kubernetes controller framework. This daemon creates virtual networks on demand, for each Continue reading
