In my last post, I described how to automate the deployment of the Cisco Virtual Wireless Controller in an OS X VMWare Fusion environment using Ansible. In this article, I will discuss how you can automate deployment of the Cisco Cloud Services Router (CSR) 1000v using VMWare Fusion and Ansible. As you will see, the deployment for the CSR 1000V...

In this article, I will describe how to deploy Cisco’s Virtual Wireless Controller (vWLC) on VMWare Fusion using Ansible. Although Ansible is most often used for deploying infrastructure and applications or orchestrating continuous delivery workflows, it can be used to automate almost any task. I will create an Ansible playbook that will automate all of the manual tasks you would...

In my last post, I introduced Seastar and DPDK and how to run Seastar with DPDK on an Intel NUC. In this post, I’m going to benchmark the performance of Seastar/DPDK with a number of other web frameworks. Here is the complete list of frameworks that will be benchmarked: Node.js Go (using Gin web framework) Vert.x Seastar (using Linux network...

The DPDK (Data Plane Development Kit) is an exciting project that delivers high performance networking by allowing low-level networking functions to be performed in user space applications, instead of in the Linux kernel. If you are not familiar with DPDK, you can find out more information at the following links: http://dpdk.org http://dpdk.readthedocs.org/en/latest/index.html In this article, I will show you how...
