Summary This chapter expanded on hybrid networks, which were introduced in Chapter 6. We went into more detail about how on-premises data centers and networks connect to AWS cloud services. You learned about site-to-site VPN connections that use the public Internet to connect into AWS. An important part of using a VPN is to provide […]

traceroute traceroute is a useful command-line utility in your troubleshooting arsenal and is used to show the path taken over an IP network from source to destination. It will also tell us the delays to each router hop and, if configured, the DNS name of all the indeterminate routers. The utility is included in every […]

Testing and Validating Connectivity Between Environments Network testing and validation is an important skill for any networking engineer, and in-depth knowledge is expected for you to pass the Advanced Networking exam. Network testing is an ongoing process that begins when you first configure the network. There are many monitoring, logging, and testing tools offered as […]

Transit Gateway The AWS Transit Gateway service is a central regional virtual router that is used to connect VPCs with on-premises facilities. The Transit Gateway service acts as a centralized core router for your hybrid network. The hub is designed to reduce the complexity of connecting multiple locations and VPCs by making only a single […]

Gateways A gateway is a device or software that interconnects dissimilar systems. A gateway translates between two networks with different protocols, as shown in Figure 7.5. Routers and gateways are terms that are often used interchangeably, and while there is a lot of overlap in functionality, there are also differences that distinguish the roles they are used for. […]

Switching Layer 2 switching forwards Ethernet frames at the data link layer, which is layer 2 of the OSI model. The switch examines the Media Access Control (MAC) address of each frame and builds a forwarding table based on the source MAC address to determine the interface where the frames are to be forwarded. All […]

Direct Connect Locations AWS Direct Connect locations are located throughout the world and are not located in AWS facilities like availability zones are. Third-party data centers are used to house the AWS DX routers. Customers contract with service providers or supply their own network equipment located in the same data centers as the AWS DX […]

Accelerated Site-to-Site VPN Connections There is an option to use the AWS VPN Global Accelerator to decrease the network latency and congestion experienced when routing your VPN traffic over the public Internet. The AWS accelerated site-to-site VPN is routed to the nearest Global Accelerator edge location and then traverses the internal AWS global network instead of […]
