# Setup node using AWS Marketplace

Setup node using cloud prebuilt image (AWS Marketplace).

You can use cloud service such as Amazon Web Service to obtain node infrastructure and public IP address automated by marketplace product. This can be chosen by who does not have physical space to store computer and own public IP address or who is not familiar with remote terminal environments.

This step-by-step guide will walk you through creating a new node and connecting it to an existing Orbs network.

## Prerequisites

* Web browser (Chrome is recommended)
* AWS account
* AWS Elastic IP (Optional)
* Guardian Wallet (for stake/rewards) - HW wallet recommended
* A private key and public address of ERC20 address for node operation. For details see [below](#allocate-orbs-node-address-and-private-key)
* Ethereum RPC endpoint url ([Infura](https://www.infura.io/) free tier is okay)

## Allocate Orbs Node address and private key

The Orbs Node address is a standard Ethereum Address. This address is used for (1) signing blocks on the Orbs network, and for (2) sending transactions to Orbs PoS smart contracts on Ethereum. Therefore, the Orbs node stores and uses the node address's private key. As such, the private key should be different from the Guardian private key.

During normal operation, Orbs node automatically sends transactions to the PoS smart contracts on Ethereum (e.g. to execute reward distribution or to signal that it is in sync with the network and ready to enter a committee). The Orbs Node address should hold enough ETH to fund the gas for transactions sent to the PoS contracts. It is the Guardian's responsibility to periodically verify the Orbs node address has a balance of at least 0.5 ETH.

Note - To complete registration, the Orbs node address is required to start with at least 1 ETH.

Orbs Node address and private key should be generated in a secure fashion and the private key is required during node deployment (see below).

The Orbs Node address is also required during the [Guardian Registration phase](/pos/orbs-pos-universe/becoming-the-guardian/register-your-guardian-on-chain.md).

The Orbs address may be modified, by updating the registration. Prior to a node address change, the node should be teared-down and redeployed.

***The Orbs Node private key should be securely stored.***

If needed, use [wallet generator](https://iancoleman.io/bip39/) to create new wallet provides privatekey.

      2. **Ethereum RPC endpoint** (ie. `https://mainnet.infura.io/v3/06b6...b2d7e`)
      3. **Orbs node address without 0x** (ie. `246abE5D...000`)

* **BoyarStatusUrl:** http\://\<your\_ip\_address>/services/boyar/status

## Verify your Node is deployed correctly

{% hint style="info" %}
Try to connect BoyarStatusUrl with browser and check that all the services started without errors
