 ## The hard way

 #### Running locally
 
-The first web app I built was a social network back in 2015, written in PHP with a MySQL database and hosted from my school laptop so my friends could access it over the local network.
+The first web app I built was a social network back in 2015, written in PHP with a MariaDB database and hosted from my school laptop so my friends could access it over the local network.
 
 At this point in time I knew nothing about running web servers or databases, I just started a magical program called [XAMPP](https://www.apachefriends.org/) and everything ran for me. 🤷🏽‍♂️
 
 #### Running on a live server
 
-I eventually moved it to an Ubuntu VPS where I needed to install a full AMP (Apache, MySQL, PHP) stack myself, and quickly realised that sometimes code that worked locally **didn't work on the server**, but better yet, a simple `sudo apt update && sudo apt upgrade` would sometimes just **suddenly break my app** since it updated the dependencies installed natively on the system. 🤯

 Given how difficult it was to keep the code working locally and live, I ended up ditching my local environment and just developing directly on the live server via SFTP, with **zero version control** and patching any breakages that happened when I ran a system update. Feeling better about your own practices yet? 🤦🏽‍♂️
 
 #### Running multiple web apps
 
-When the time came to serve more websites, I found [Apache virtual hosts](https://httpd.apache.org/docs/2.4/vhosts/) did the trick, but then they all used the same version of Apache (importantly, PHP), so a system update that introduced a breaking change would break all my websites at once. 😭

+Fast forward almost a decade and I've found a perfect balance for me that leverages containerisation without the complexity level of Kubernetes.

 K8S was overkill for me, but I could still lean into Docker as a deployment platform.
