Automation is getting more and more momentum. I attended a training recently and none of the other people in the room ever wrote code but all of them where interested and somehow feared automation Let’s recap one thing. Automation we have today will replaces typing in CLI or in the GUI with some code. That’s it. For ACI well use Postman or Ansible instead of the GUI or the CLI. For IOS NSO or DNA Center will replace the CLI but still we’ll need people writing scripts and core.
Asset management, documentation and monitoring are important parts of any IT Ops team but at the same time they are boring, repetitive, error prone. Last summer I spent some time investigating the possibility to integrate open source projects I like to create a Minimum Viable Product for asset management/monitoring and learn something during the process. This is far from being something complete or production ready but I think it worth to share before it get lost in some abandonware repository on my laptop.
Automation and programmability is not a new topic for me. Having studied Information Technology in High School I’ve always coded somehow, never making it my primary focus but always using it as a tool to make my life easier. I remember a script I did in Pascal to create a menu to load custom maps for Doom II instead of using the CLI. It would be great to find it again but it’s very unlikely because I trashed so many PCs and hard drives since, well, at least I hadn’t bitcoins stored there!
This week I’ve attended the Network Automation Seminar organized by Reiss Romoli. The speaker was the great Ivan Pepelnjiak! I was happy to meet Ivan again after NFD16. At the event I joined old and new friends: Andrea, Nicola, Paolo and Tiziano. Are these networkers or programmers? ;) @ioshints @adainese @nmodena @ReissRomoli @Paolo_Lucente #networking pic.twitter.com/RwjX6h2Mng — Gian Paolo (@gp_ifconfig) October 19, 2017 Content is king In two days Ivan presented tools, solutions, concepts and a lot of use cases of network automation.
Automation is today a word that can be both scaring and exciting at the same time. The scary part is often related to the question: will robots steal my job? Federico Pistono says that’s ok. We read articles about how many jobs will not exist anymore soon, and sometimes how new jobs will be create to support automation. The most advanced analysts try to predict how a society can survive with massive unemployment.
Summertime usually means a busy period for Network Engineers, customers are on holidays and we have the opportunity to performs all the changes that impact network connectivity. For me this usually means core switch replacement. Today I was moving a configuration from an HP8200 to a Cisco 4500, taking care of all the details of ports, trunks, vlans. From this: to this: When a task is manual, boring, repetitive and error-prone my automation skills came to help.
