Getting Started with Ansible for Juniper - Part 1

Hi .. I recently had a wonderful oppportunity of working with Juniper High-End Firewalls and like an icing on the cake, to configure them as a code. Although my “wonderful” may sound a bit sarcastic, it really is not.. well, at least not 100% because the path of IaaC was not as simple as I expected it to be :( The reason for that is not surprising though: This was to be achieved in a time-constrained setting (and, if my past tells me anything, it is – if you don’t do it now, you will probably keep chasing time for it).

Create your website using Terraform

Hi .. This is a post on how I automated the process of building, testing and deploying my website using Terraform and TravisCI. For readers who came for code, I don’t want you to spend time scrolling all the way.. so, you can find my github link here: github:website Why am I writing this blog? Well, to be honest.. this is my first blog and I feel this urge to jot down the entire process of deploying your website into well-defined words because it’s worth it!
