In this tutorial i recomended using Contabo (choose the NVME DISK!) and Vultr (SSD are also good for this one).

Minimum Hardware Requirement:
CPU: 4 or more physical CPU cores
RAM: At least 8GB of memory (RAM)
Disk: At least 160GB of SSD disk storage
Connection: At least 100mbps network bandwidth
OS: Ubuntu 20.04

Automatic installation script

wget -O source.sh https://raw.githubusercontent.com/xsons/TestnetNode/main/Source/source.sh && chmod +x source.sh && ./source.sh

sourced status 2>&1 | jq .SyncInfo
