AWS Network 102 – Connection

  • VPC Endpoints: Privately connect your VPC to supported AWS services. Interface Endpoint (PrivateLink), Gateway Endpoint (S3, DynamoDB)
  • VPC Peering: Networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses. A VPC peering connection helps you to facilitate the transfer of data. You can establish peering relationships between VPCs across different AWS Regions (also called Inter-Region VPC Peering)
  • VPN:secure connections between your on-premises networks, remote offices, client devices, and the AWS global network.AWS Site-to-Site VPN creates encrypted tunnels between your network and your Amazon VPC or AWS Transit Gateways. For managing remote access, AWS Client VPN connects your users to AWS or on-premises resources using a free VPN software client.
  • Direct Connect:securely connect your AWS environment to your on-premises data center or office location over a standard 1 gigabit or 10 gigabit Ethernet fiber-optic connection. AWS Direct Connect offers dedicated high speed, low latency connection, which bypasses internet service providers in your network path.
  • Nat Gateway: enable instances in a private subnet to connect to the internet or other AWS services, but prevent the internet from initiating a connection with those instances.NAT gateways are not supported for IPv6 traffic—use an outbound-only (egress-only) internet gateway instead.To create a NAT gateway, you must specify the public subnet in which the NAT gateway should reside.You must also specify an Elastic IP address to associate with the NAT gateway when you create it.
  • Egress-only internet gateways:An egress-only internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows outbound communication over IPv6 from instances in your VPC to the internet, and prevents the internet from initiating an IPv6 connection with your instances.
  • Global Accelerator: improves the availability and performance of your applications with local or global users. It provides static IP addresses that act as a fixed entry point to your application endpoints in a single or multiple AWS Regions, such as your Application Load Balancers, Network Load Balancers or Amazon EC2 instances.
  • Transit Gateway: connects VPCs and on-premises networks through a central hub.Inter-Region peering connects AWS Transit Gateways together using the AWS global network. Your data is automatically encrypted, and never travels over the public internet.
