I use a VPS with:
1 Cores
2 GB RAM
DDoS Protection
20 GB SSD Cloud Storage
24/7/365 Tech Support
All this for 3.65EUR/month (VAT included) and is running just fine for Idena node.
DigitalOcean and Vultr are just too expensive in my opinion at $10 + VAT, just because they can rape you.
Which Hosting provider is this ? i had some Azure credit lying around , so i hosted in azure . But 600GB bandwidth will be too much in Azure. Guess i need to switch to your provider's VPS.
