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.
AWS services can be deployed and managed in code form in a development environment using various software, but the easiest and most convenient environment to use is the web-based AWS Management Console .
In order to create and configure a specific service, you need to be able to use various options. However, if you approach the code without knowing how the service is created and operates or how the detailed options are configured, you will often encounter difficulties.
So, if you look at the detailed settings and options in the web-based AWS management console and create services by seeing them with your own eyes, you will understand them better and it will also be helpful for writing or managing code later.
Those who have personally developed AWS network services from start to finish have a higher level of understanding. And not only are they highly skilled in utilizing the services, but their skills are also likely to improve in the future. In this workshop-style online lecture,
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.
Control inbound and outbound traffic at the instance and subnet level by configuring security groups and Network Access Control Lists (NACLs) and setting rules.
Configure and set network connectivity information for AWS resources using Elastic IP (EIP) and Elastic Network Interface (ENI).
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.
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.
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.
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.
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.
Build a more extended network by connecting your virtual external network to your AWS network using Site-to-Site VPN.
thank you very much
The practice environment was very well-organized, which I really liked! The concise explanations were also helpful for understanding. Thank you!
Thank you!
An excellent lecture that even non-majors can fully understand!
