It is important to remember that while AWS Global Accelerator uses IP Anycast to steer clients into the nearest edge POP, it is much more than that. In a similar way to Amazon CloudFront, when customer connections enter an edge POP, they are terminated on a proxy server. This means that the three-way handshake – […]

Amazon CloudFront functions – Utilizing the Capabilities of the AWS Global Network at the Near Edge
As noted previously, AWS Lambda@Edge functions execute inside the RECs. That’s better than having to run them in the core regions – but what can we do inside the edge POPs themselves? That is where we must use Amazon CloudFront functions: Figure 8.13 – Visualization of where Amazon CloudFront functions and AWS Lambda@Edge run These […]
Service pricing – Using AWS Wavelength Zones on Public 5G Networks
It is important to be aware of the pricing difference for AWS services when they are deployed to a Wavelength Zone versus a standard availability zone. The next figure shows an example of the difference for different EC2 instance types in us-east-1 (Northern Virginia region) and us-east-1-atl-1a (Atlanta Wavelength Zone): Figure 7.25 – On-demand pricing […]
Accommodating device handoff – Using AWS Wavelength Zones on Public 5G Networks
It is important that applications that span multiple geographies take into consideration the possibility that the closest AWS Wavelength Zone might change as a client device moves. A car with a 5G modem in it doing vehicle-to-everything (V2X) could easily drive from Boston to Philadelphia via New York – necessitating a switch between those three […]
Carrier gateways – Using AWS Wavelength Zones on Public 5G Networks
AWS Wavelength Zones use a special construct similar to an internet gateway called a carrier gateway. This is how traffic will route to/from the MNO’s network to EC2 instances or containers you attach to the subnets in your AWS Wavelength Zone: Figure 7.5 – Creating a carrier gateway for an AWS Wavelength Zone Routing tables […]
Introduction to AWS Wavelength Zones – Using AWS Wavelength Zones on Public 5G Networks
In Chapter 3, we discussed how mobile network operators (MNOs) are eager to build multi-access edge computing (MEC) offerings to develop new revenue streams for their 5G infrastructure investments. However, they are not cloud service providers (CSPs). They usually do not have the in-house expertise to operationalize a customer-facing multitenant service such as this. Enter […]
