Beware The Latest Infrastructure Tools
Proceed with caution when deploying new tools to avoid costly outages.

Hi folks! After plowing through my home lab, I’m ready to walk you through setting up RHV-M in a “self-hosted engine” (HA) configuration. I’ve talked about this in some previous articles if you need to familiarize yourself with what the significance is or why someone might want to go with this approach over a standard deployment.
Let’s get to it.
Pre-Setup
Sounds funny, right? “Pre-setup”.. like you’re going to setup before you setup? But really, that’s what you need to do. In this case, everything needs to be right before you just dive right into the deep end of the lake, or you’re going to hit rocks. What I mean is that your underlying environment needs to be right, or things will not go smoothly at all.
Specifically, you’re going to need to pay attention to the requirements of the hosts and RHV-M software.. the specs are well published. For example, you need to have fully qualified domain names for all of your hosts and RHV-M, and they need to resolve (forward and reverse!) in some form of DNS. Just using “/etc/hosts” isn’t going to cut it here.. Don’t have running DNS in your lab, don’t sweat it, look Continue reading
NFV is a critical step in the 5G evolution.
Enterprises gain unified app control from co-location facilities.
Another great blog post by Russ White: DNS is part of the TCP/IP stack, get used to it.
You might also want to tell application developers hard-coding IP addresses or anyone else believing in using /etc/hosts files instead of DNS that those things stopped being sexy around 1980.
Network Automation is just getting started and it’s odd to say that as IT professionals from other technology disciplines are always surprised to see how much manual interaction there still is between the networking engineering/operations teams and the actual devices they manage.
I’ll never forget the days in 2012-2013 performing my best Google searches to find ways to program or to automate network routers and switches. I didn’t care what programming language was being used or even what tool, but I found nothing. Every time I heard someone say they were using a network script, I’d say “email it to me, that sounds interesting.” Unfortunately, 100% of the time, it ended up being a notepad or a Word file, not a script. What a bummer.
I like to think I’m a solid Googler too. It was amazing though - there was near nothing. Do a search today on network automation or network programming and you’d be amazed on what you’ll find - we’ve come a long way in the past 36 months with respect to network automation, but I truly believe we’re still in the 2nd or 3rd inning (if we were playing a game of baseball, of course).

Big data, IoT, and other applications are changing cloud computing, according to Cisco's sixth annual Global Cloud Computing Index.
A wide array of supplementary technologies, including adjustments to the NIC, are being built to deliver high performance NFV for service providers.
