Welcome!

I'm here to help you understand the concept of the "Multitier architecture" and give you real examples of how a 3-tier architecture network can be implemented on the AWScloud using the native services.

Here you will understand, how to your environment, which should be isolated, provide network connectivity and the ability to track your traffic through all level of tiers. And based on traffic hopes, you will see how traffic can go through all network points on AWS, such as Internet Gateway and NAT gateways.

Workflow of the course:

• Multitier architecture concept

• Review schemas of 4-tier and 3-tier architectures

• Prepare the network from the scratch on AWScloud using VPCand subnets

• Preparation of Internet Gateway and route for WEBtier

• Preparation of public NATgateway for App tier and internet connectivity there

• Preparation of private NATgateway for DB tier and internet connectivity there

As a result of this course, you will receive the experience of the building of network 3-tier architecture on AWScloud and the ability to use this experience on your future projects!

Also, you will see here, how traffic will go through this schema on all levels of tiers.
