Static content like images/videos should go into an S3(-compatible) bucket (or something similar). This allows you to host Strapi in a high available (HA) setup (> 1 instance). If you are not familiar with infrastructure deployment try an ‘app platform’ that several different providers offer. Otherwise, Kubernetes is always a very flexible and scalable way to deploy containerized environments. Both are available at DigitalOcean.
Hope this helps!
