On a typical day, the website uses few resources, but during promotions, the load increases several times over.

I'm looking for a VPS with 8 CPU cores, 16 GB of RAM, NVMe storage, and scalability. Backups and monitoring are also important.

I'm checking out hostpro.com. What's better in this case: getting a server with plenty of headroom, or sticking with moderate resources and handling the spikes with caching, a CDN, and database optimization?
