This is the repo for my (Hungarian) Twitch streams where I speak a bit about scaling an application. (There's also a Youtube backup for the videos here: https://youtube.com/playlist?list=PLOIpbzPG9JERPYLml4sUiQ8sjt2awKu1J )
Each scale# folder more or less the same basic message board application, but I'll try to introduce new scaling methods and summarize the positive and negative sides of them.
Apps:
scale0/- Basic application where you can save a message and then retrive the message list. Nothing special, just a simple MySQL database save an fetch.scale1/- First step for the actual scaling with some Redis based cache in the application.scale2/- Second step for the scaling with read/write database replica connections.scale3/- Let's have some real async functionality with a message queue!k8s/- A minimal kubernetes example with a simple deployment, service and ingress config.
