Key AWS network diagram elements for building AWS VPCs:

• VPC (Virtual Private Cloud): The fundamental building block of your network infrastructure in AWS, allowing you to create a logically isolated section within the cloud
• Subnets: Subdivisions of a VPC that enable you to allocate and manage IP addresses for different segments of your network
• Availability Zones: Physically separate data center locations within a region, providing fault tolerance and high availability for your resources. Deploying subnets across multiple availability zones ensures resiliency
• Internet Gateway: A horizontally scalable gateway that allows communication between your VPC and the internet, facilitating inbound and outbound traffic
• Route Tables: Determine the traffic flow between subnets, availability zones, and the internet. They define the routes for network traffic within the VPC
• Security Groups: Acts as a virtual firewall for your instances, controlling inbound and outbound traffic at the instance level
• Network Access Control Lists (NACLs): Operate at the subnet level and provide an additional layer of network security by controlling inbound and outbound traffic at the subnet level
• NAT Gateway: Enables instances in private subnets to access the internet while keeping them secure by not exposing their direct IP addresses
• VPN (Virtual Private Network) Connections: Establish secure connections between your on-premises network and your VPC, allowing you to extend your network seamlessly into the cloud
• Direct Connect: Provides a dedicated network connection between your on-premises environment and AWS, offering a more reliable and consistent network experience
• Application Load Balancer / Network Load Balancer: Load balancing solutions that distribute incoming traffic across multiple targets, such as EC2 instances or containers, ensuring high availability and scalability for your applications
• Transit Gateway: Simplifies network connectivity between multiple VPCs and your on-premises networks, acting as a central hub for routing traffic and enabling seamless communication across a complex network architecture
• VPN Gateway: Allows you to establish secure, encrypted connections between your VPC and your on-premises network or remote networks using IPsec VPN tunnels
• VPC Endpoint Gateway: Enables secure communication between your VPC and supported AWS services over the Amazon network, without the need for an internet gateway or NAT device
• VPC Peering Connection: Establishes a direct network connection between two VPCs, allowing them to communicate with each other using private IP addresses as if they were part of the same network
• VPC Endpoint Interface: Enables private connectivity between your VPC and supported AWS services without requiring an internet gateway, NAT device, VPN connection, or public IP addresses

AWS Network Diagram With Load Balancer And EC2 Targets

This AWS network diagram illustrates a dynamic setup where EC2 instances are deployed in an auto-scaling group within the public subnet. These instances serve as targets for an Application Load Balancer (ALB), enabling efficient distribution of traffic across the instances. This diagram provides a visual representation of the scalable architecture, showcasing how the auto-scaling group and ALB work together to handle varying levels of demand and ensure high availability of the application.

Three-tier AWS Network Diagram

The three-tier AWS network diagram showcases a comprehensive architecture that includes both external and internal Application Load Balancers (ALBs). The ALBs are configured to distribute traffic to EC2 instances running in auto-scaling groups, serving different parts of the application logic. In the public subnet, EC2 instances handle presentation and part of the application logic, while in the private subnet, EC2 instances serve the rest of the application logic. Private subnet instances can securely access an RDS database with a read replica for optimized read-heavy application scenarios. To enable internet access for the private subnet instances, a NAT Gateway is deployed. This AWS network diagram provides a detailed visualization of the infrastructure setup, highlighting the various components and their interactions in the application architecture. Cloudviz.io, an AWS network diagram generator, can efficiently capture and present this complex network configuration.
