Physical Layer: This layer deals with the physical components of the network, such as cables, switches, and network interface cards (NICs). In AWS, this corresponds to the physical network interface that connects your virtual machines to the network.
Data Link Layer: This layer is responsible for node-to-node data transfer and error detection/correction. In AWS, this is represented by the Virtual Private Cloud (VPC), which provides the underlying network infrastructure for your resources.
Network Layer: This layer handles packet forwarding, including routing through different routers. In AWS, this is represented by Amazon VPC, which allows you to create isolated networks in the cloud.
Transport Layer: This layer provides end-to-end communication services for applications. In AWS, this is represented by Elastic Load Balancing (ELB), which distributes traffic across multiple servers to ensure high availability and reliability.
Session Layer: This layer manages sessions between applications. AWS does not have a direct equivalent for this layer, as session management is typically handled by the application layer.
Presentation Layer: This layer translates data between the application layer and the network. AWS does not have a direct equivalent for this layer, as data translation is typically handled by the application layer.
Application Layer: This layer provides network services to end-user applications. In AWS, this is represented by Amazon API Gateway, which provides a fully managed service for creating, deploying, and managing APIs.
