Here's a simple example of how you can automate scaling image transformations. Tech used: Node.js, Sharp, Express. App platform: Zerops - nodejs expressjs

import http from 'k6/http'; import { check } from 'k6'; export default function { const baseUrl="https://.usc1.contabozerops.com" const width=300 + Math.random * 1000 const height=300 + Math.random * 1000 const angle=Math.random * 360 const res=http.get check=> r.status===200, }); }This will simulate 100 users requesting the image service as fast as possible for 120 seconds.

Our example is mainly a CPU-intensive task so you will see the number of vCPUs rise -- vertical scaling -- and after a short time also see more containers being created -- horizontal scaling. Please refer to the following screenshot where you see many vCPUs and 4 containers.
