The following steps are required to build a network using Amazon Cloud:

Sign up for an AWS account: First, you need to visit the Amazon Cloud official website and sign up for an account. Fill in the necessary information, such as name, email, password, etc., and then complete the registration.

Create a VPC: In AWS, a virtual private cloud (VPC) is a logically isolated network environment in which AWS resources can run. To create a VPC, you need to specify the IP address range, subnet, route table, etc.

Create a subnet: In a VPC, a subnet is an IP address range in which EC2 instances can run. To create a subnet, you need to specify the IP address range, availability zone, etc. of the subnet.

Create an Internet gateway: An Internet gateway is a virtual device that can route traffic from a VPC to the Internet. To create an Internet gateway, you need to attach it to a VPC and create a route table to route traffic to the Internet gateway.

Create a security group: A security group is a virtual firewall that controls traffic in and out of an EC2 instance. To create a security group, you need to specify inbound and outbound rules, such as allowing SSH connections.

Create an EC2 instance: An EC2 instance is a virtual machine running in AWS where you can run applications. To create an EC2 instance, you need to select an operating system, instance type, storage, etc. that suits you, and place it in a subnet in your VPC.

Connect to an EC2 instance: To connect to an EC2 instance, you can use an SSH client. You need to use the public IP address and private key file of the EC2 instance to connect.

The above are the basic steps to set up a server network connection on the Amazon cloud. In actual operation, more configuration and adjustment are required to meet your needs.
