What will happen when you combine GPUs and persistent storage? It seems to me that the ever-increasing application of persistent storage technologies in lots of difference places is going to change lots and lots of things. Is the era of the storage admin over ?

At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. Russell Pope at Kovarus recently wrote about using security groups to manage the VMware NSX distributed firewall. I knew Microsoft was cozying up to Linux, but I honestly didn’t expect they would port SQL Server to Linux.

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. NixOS seems to be an interesting re-think of a Linux distribution.

Anthony Burke gives a little bit of a sneak peek at some functionality from the upcoming v3 release of PowerNSX: searching NSX Distributed Firewall (DFW) rules. The article supplies lots of useful information, but I really would’ve liked some concrete examples of how to glue these pieces together. Cody De Arkland shows you how.

If you’re looking for more examples of how to incorporate these sorts of tools into your own network automation workflow, I’d recommend having a look at this article. Here are some general guidelines for configuring syslog forwarding on a Cisco ASA firewall. The workflow incorporates Ansible, git, Jenkins, and Gerrit. Servers/Hardware.

In the event you’re interested in an idea of how much latency the use of in-kernel hypervisor firewalling (such as that offered by VMware NSX) adds, have a look at this article by Sean Howard. Greg Schulz—who normally tends to focus on storage-related topics—has a post providing an overview of the Ubuntu 16.04 “Xenial Xerus” release.

This post provides some examples of shared control planes (and thus shared failure domains) within networking. 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?”

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. Pradipta Kumar Banerjee has an article on using local storage for instances in OpenStack. Red Hat Enterprise Linux Atomic Host (how’s that for a mouthful?) DVM looks handy.

Why might that be the case?

The “gotcha” is that these software stacks haven’t been written yet, so the idea of repurposing hardware from switch to firewall to load balancer is still a bit of a unicorn. First, here’s a workaround to the fact that vCA doesn’t (yet) do cloud-init, which makes injecting SSH keys into Linux instances a bit difficult.
