At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. At the recent OCP Summit, Microsoft introduced Software for Open Networking in the Cloud (SONiC). Russell Pope at Kovarus recently wrote about using security groups to manage the VMware NSX distributed firewall.

I highly recommend you read the entire post, but in short the five skills Matt recommends are software skills (which includes configuration management and software development tools like Git ), Linux, deep protocol knowledge, hypervisor and container networking, and IPv6. What does this mean? You’re welcome.

A software application has numerous moving parts, which, if not effectively maintained, will definitely affect the final quality and end user experience. With over 1300 modules, Ansible simplifies several aspects of IT infrastructure, including web, database, network, cloud, cluster, monitoring, and storage.

A discussion of “statefulness” brought me again to Ivan’s post on the spectrum of firewall statefulness. Cisco shared some thoughts on what they termed a “software-only” approach; naturally, they have a different vision for data center networking (and that’s OK). This looks interesting.

In the way virtualization abstracts & configures the software world (O/S, applications, etc.), Infrastructure Orchestration abstracts and defines/configures the infrastructure world (I/O, NIC cards, HBA cards, storage connectivity, LANs, switches, etc.). They discovered, however, that resulting complexity would be overwhelming.

In this post , Jakub Sitnicki digs way deep into the Linux kernel to uncover the answer to the question, “Why are there no entries in the conntrack table for SYN packets dropped by the firewall?” Linux malware is getting more sophisticated. ” Get ready to get nerdy!

This post by Ranga Maddipudi shows you how to use App Firewall in conjunction with VXLAN logical networks. I must disagree with some of his statements regarding what software-defined networking is and is not and where it fits , written back in April. App Firewall? Venky explains it in this post.

The use of VMware NSX for microsegmentation is a really popular use case, and so the topic of scripting distributed firewall (DFW) rules often comes up. I predicted a couple of years ago that Intel SGX (Software Guard Extensions) was going to be HUGE (see here ). Red Hat Enterprise Linux Atomic Host (how’s that for a mouthful?)

So after elevating a previous to it, we could conduct a more extensive recon and on the Jupyter Notebook environment So after conducting more thorough recon on the Jupyter Notebook environment, we found out that the Jupyter Notebook had some local firewall rules restricting network access. Why might that be the case?

Tom’s key point is that disaggregating software from hardware—which is kind of a given if you’re buying whitebox networking gear—gives you the (potential) flexibility to repurpose network gear based on the software running on it. I came across a couple of useful vCloud Air-related posts that I wanted to share here.
