Building Your Own AWS Cloud Network - Basics

How much of AWS's network services can you use?

When building an architecture based on the AWS cloud, many people first think of EC2 for servers, S3 for storage, and RDS for DB. They also think a lot about how to apply new technologies such as Docker, Container, and Kubernetes, which are widely used these days.

Of course, these are important services for the architecture to actually work, but these services do not operate independently. As with all IT infrastructures, all AWS services are ultimately connected to the network, and traffic moves and communicates through this network for the architecture to actually work. In fact, many of the causes of system errors or failures are found in network-related services.

So , it is very important to have experience in creating and utilizing network services directly, but since many people only understand it theoretically, I have seen many people having difficulties when carrying out projects or during troubleshooting.

To this end, we have prepared a hands-on lecture centered on practice that will allow you to build a simple cloud network using AWS's basic main network services, understand the traffic flow in the architecture, and implement an actual network yourself.

🧐 Course Features

📖 What you will learn

1⃣ Basic Public Network Configuration

Configure VPC, Subnet, Internet Gateway, Route Table, and create EC2 instances to create a simple public network that can communicate directly with the outside world.

2⃣ Network communication control using security group and NACL

Control inbound and outbound traffic at the instance and subnet level by configuring security groups and Network Access Control Lists (NACLs) and setting rules.

3⃣ Elastic IP (EIP) and Elastic Network Interface (ENI)

Configure and set network connectivity information for AWS resources using Elastic IP (EIP) and Elastic Network Interface (ENI).

4⃣ Network distribution through Application Load Balancer

Configure a network environment that distributes traffic using Application Load Balancer, and configure path-based routing that distributes traffic according to specific paths or conditions, and fixed session routing that routes to a fixed target for a certain period of time.

5⃣ Private network and NAT configuration

Connect to the EC2 instance created in the private network through the Bastion host, and configure a network through which the EC2 instance located in the private network can communicate with the outside world through the NAT Gateway.

6⃣ Connecting Private Networks and AWS Services via Endpoint

Using VPC Endpoint, you can configure a network that allows EC2 instances located in a private subnet to access, use, and manage AWS services outside of the VPC.

7⃣ Network expansion through VPC Peering

Use VPC Peering to connect two different VPCs located within the same Account and Region and configure a network that can communicate with each other.

8⃣ Network Expansion via Transit Gateway

Use Transit Gateway to connect three different VPCs located within the same Account and Region and configure a network that can communicate with each other.

9⃣ Configure a virtual hybrid network with Site to Site VPN

Build a more extended network by connecting your virtual external network to your AWS network using Site-to-Site VPN.
