DevOps/CloudOps Engineer

Overview

The DevOps/CloudOps Engineer is primarily responsible for ensuring that cloud based Infrastructure is designed and deployed in a secure manner. These responsibilities include delivering solutions that satisfy functional and user requirements; developing, maintaining and troubleshooting cloud based services and network security systems; preventing misuse and malicious behavior; outlining constraints and restrictions within security policy; scripting and documenting processes.

This engineering group at Rooms To Go uses "serverless" infrastructure where possible. Their primary responsibility is architecting, implementing, maintaining, and monitoring AWS services. Where possible we use (pay for) existing services instead of re-solving "solved problems".

A oneliner for testing redirects
View redir_test.sh
#!/bin/bash
# The following line defines a bash function and is designed to be copy-pasta-ed into your terminal and used as shown on the last line of this file. I'm only putting it in a script to get it on gist
redir_test(){ curl -svLo /tmp/redir_test.out "$@" 2>&1 | grep -E '^(> Host|> GET|< HTTP|< location|[<>]\s*$)'; }
# BONUS: One super-useful use of this is to test your readiness to respond to future DNS changes. That can be done like so:
# redir_test -H 'Host: www.example.com' https://192.168.0.101/
# This assumes that your server at 192.168.0.101 is set up to serve www.example.com and this simulates what `curl https://www.example.com/` would do if DNS returned 192.168.0.101 when doing a lookup on www.example.com
