To understand the full benefits of utilizing the AWS global backbone, we must first start at the foundational units that make up the AWS cloud – AZs. CLOS (leaf/spine) topology The physical network fabric in AZs is a fully Layer 3 CLOS architecture, also known as a leaf/spine design. To simulate Layer-2 adjacency between EC2 […]

Overview of the AWS Global Network – Utilizing the Capabilities of the AWS Global Network at the Near Edge
The AWS Global Network is the cornerstone of everything AWS does. It represents an expansive and cutting-edge infrastructure designed to offer unparalleled performance, reliability, and security. It’s more than just a network; it’s a testament to AWS’s commitment to delivering a seamless cloud experience to businesses and end users across the world. By understanding and […]
AWS Cloud WAN – Utilizing the Capabilities of the AWS Global Network at the Near Edge
For relatively simple, static situations like what we’ve described so far, AWS Direct Connect SiteLink is sufficient. But let’s say we want to build a SaaS offering on top of AWS that connects to physical elements at the edge. Some of these are in true data centers, with AWS Direct Connect links set up to […]
Traffic dials for endpoint groups/regions – Utilizing the Capabilities of the AWS Global Network at the Near Edge
By default, these are set to 100% for all endpoint groups attached to a listener. This results in the default behavior where connections always go to the closest region. When these values are altered, things can get a little tricky to understand, so let’s walk through some examples: Figure 8.20 – AWS Global Accelerator traffic […]
TCP termination – Utilizing the Capabilities of the AWS Global Network at the Near Edge
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 […]
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 […]
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 […]
