1- Where to buy VPS

The first thing that is needed to participate in Node Testnets is a VPS server

In order to buy a VPS ( Cloud Server), I introduce several good (in my opinion) foreign & Iranian providers with and without crypto payment with brief information

Provider	Payment	Discription
Hetznr	Credit card - need KYC	Best Hosting , expensive , auction servers are good
Contabo	Credit card - need KYC	Cheap but for a very few nodes we had bandwidth issues
Hostbrr	Crypto	Cheap to Normal pricing
Bartarvs	Rial - Crypto	Iranian - Myloc & Contabo cloud servers are cheap and best
Aeza	Crypto	Best for hourly servers

I'm not RESPONSIBLE nor AFFILATED with any of these providers. I just used them before, and I think they are good choice. You can choose wherever you think is better

2- What system to buy

Before buying a VPS, we must consider several components to choose the required system

• CPU: Usually, 4core to 16core
• Ram: Usually, 4GB to 32GB
• HDD, SSD: Projects always consider the hard disk of the Nodes to be higher than required. In few nodes such as Prover or Validator in Active-set maybe a lot of hard disk is needed. Minimum is better to be 60
• Operating-system must be Ubuntu, Ubuntu 22 is usually compatible with every project
• VPS must be ipv4 and must NOT be NAT

3- Let's Buy a VPS

To understand better, let's buy a server from 2 Iranian and foreign providers

This is not an advice to buy from them and I just want to show you the process

After this guide, I'm not sure if they will get out of stock of their servers, you can consider creating a ticket to ask before proceeding to buy

Hostbrr

Let's list some of their servers orders:

High RAM: Memory-Optimized VPS

High RAM - Better net bandwidth: RAM-Optimized - Premium

Good CPU: AMD Ryzen 9 7950XD

Good CPU - Cheaper: AMD Ryzen 9 5950X

High SSD - Out of stock right now: Big Storage Servers

1- I pick $14.99 VPS from AMD Ryzen 9 5950X

• 4 vCore ,8GB RAM, 150 GB Storage can be a good choice for me

2- I register my Contact Information and pay with my metamask wallet through Coinbase Commence payment method

3- Install Ubuntu.22

• After payment, I wait until my server to get active in services page
• We must install ubuntu manually in Hostbrr when server is activated
