FAQs

How to choose a VPS?

Get started with a few popular VPS choices:

  • Amazon - https://aws.amazon.com/lightsail/pricing/
  • DigitalOcean - https://www.digitalocean.com/pricing/
  • UpCloud - https://upcloud.com/pricing/
  • Vultr - https://www.vultr.com/products/cloud-compute/
  • Alibaba Cloud - https://www.alibabacloud.com/product/ecs#pricing
  • Google Cloud - https://cloud.google.com/products/calculator
  • Microsoft Azure - https://azure.microsoft.com/en-us/pricing/calculator/

Recommendations from experienced validators:

  • Jose - https://medium.com/@josefcoap/elrond-vps-guide-ebfa6655cb9f
warning

Consider the price of cheap services that offer same specs as other providers at half of the price, when running a validator - the protocol dynamically phases out low performance nodes, which will lead to fewer returns for operators.

What if I have Windows?

Use a virtualization service to deploy a virtual Linux server on your Windows machine. This setup is recommended for testing purposes only. Try this tutorial, for example: https://itsfoss.com/install-linux-in-virtualbox/
