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 […]

Amazon ECS – Using AWS Wavelength Zones on Public 5G Networks
ECS is available in AWS Wavelength in two forms – Standard ECS on EC2 and ECS Anywhere. However, ECS on AWS Fargate is not supported. Applications that span multiple AWS Wavelength Zones are really intended to function in a hub-and-spoke model. While it is possible through the use of multiple VPCs and AWS Transit Gateway […]
USING PRIVATE VPC ENDPOINTS IN AWS WAVELENGTH ZONES – Using AWS Wavelength Zones on Public 5G Networks
VPC interface endpoints must be attached to subnets in the parent region. They cannot be attached to subnets in an AWS Wavelength Zone. This also needs to be considered for any services your mobile application itself directly uses. It is common for mobile devices to retrieve files from Amazon S3: Figure 7.18 – Mobile device […]
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 […]
LAW OF PHYSICS VERSUS LAW OF THE LAND – Using AWS Wavelength Zones on Public 5G Networks
The device triangulation method necessarily finds the best zone in terms of performance – but an application with compliance requirements to communicate only with servers in a certain country or state might be better served using another method. AWS Cloud Map Another approach is to maintain a central directory of carrier IPs that mobile applications […]
Amazon Route53 for load balancing – Using AWS Wavelength Zones on Public 5G Networks
For non-HTTP(s) applications or AWS Wavelength Zones outside the US, it is possible to use Amazon Route53 weighted routing policies for load balancing (see Chapter 6). However, unlike using it in standard regions or AWS Local Zones, it is not possible to use the health check feature in the normal way. This is because the […]
Differences between 5G and 4G/LTE clients – Using AWS Wavelength Zones on Public 5G Networks
Both types of devices on an MNO’s network can connect to resources in an AWS Wavelength Zone. However, the latency is dramatically different. Recall from Chapter 3 the architectural differences between 5G and 4G/LTE topologies. A 5G connection can leave an MNO’s network via one of many distributed points known as the User Plane Function […]
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 […]
SK Telecom (Korea) – Using AWS Wavelength Zones on Public 5G Networks
South Korea, a pioneer in 5G adoption, benefits from the partnership between AWS Wavelength and SK Telecom. The South Korean market, known for its high internet speeds and technological innovations, places emphasis on entertainment and smart city applications. Given the country’s love for eSports and K-pop, the collaboration ensures that streaming and gaming applications have […]
Comparing AWS Wavelength deployments across global carriers – Using AWS Wavelength Zones on Public 5G Networks
AWS Wavelength is a series of individual partnerships with carriers around the world. An EC2 instance, or ECS/EKS container in an AWS Wavelength Zone, is specifically meant to service requests coming from mobile devices on that MNO’s network. SLAs for a given mobile device around latency, jitter, and similar network parameters are specific to each […]
