Tactical edge refers to edge computing environments that support military operations. Such situations are characterized by limited connectivity, high mobility, and the most intense security requirements. At the tactical edge, the most common needs include deploying, managing, and securing the following technologies: IoT: Cameras and sensors of every description get cheaper every day. The number […]

Moving Greengrass to the SATCOM terminal – Architecting for Disconnected Edge Computing Scenarios
Imagine a situation like we had in the previous section where we want to put an IoT gateway in the middle of nowhere behind a SATCOM terminal, but for various reasons, AWS Snowcone isn’t ideal. Maybe we intend to deploy it once and never physically visit the site for 5 years. How could we run […]
Passing MQTT messages through the IoT gateway – Architecting for Disconnected Edge Computing Scenarios
Now that we’ve given you a general overview of how AWS IoT Greengrass itself is put together, we will walk through options for connecting IoT devices such as sensors and cameras as things behind the Greengrass Core device. Local MQTT broker and the MQTT bridge IoT devices can send MQTT messages directly to AWS IoT […]
Using AWS IoT services in DDIL scenarios – Architecting for Disconnected Edge Computing Scenarios
AWS has long been a leader in the IoT space. They offer a wide range of managed IoT services and customers have been operating IoT solutions on AWS at scale for over a decade. It is a very large and powerful toolbox, but at the end of the day, the challenge is right there in […]
Amazon CloudFront Embedded POPs – Utilizing the Capabilities of the AWS Global Network at the Near Edge
In addition to the 450+ edge POPs that AWS maintains around the world, there are additional dedicated POPs positioned inside the networks of many ISPs/broadband providers around the world. These are known as Amazon CloudFront Embedded POPs, and they are based on AWS Outposts Rack or AWS Outposts Server (depending on the circumstances). Figure 8.8 […]
Amazon CloudFront special request headers – Utilizing the Capabilities of the AWS Global Network at the Near Edge
In Chapter 2, we discussed the mechanisms Global Server Load Balancing (GSLB) systems such as Amazon Route53 use to determine the geographic location of a client’s IP address on the internet. Amazon CloudFront makes use of these same facilities to determine which edge location is closest to a given user so that it can steer […]
HTTP request headers and URL query strings – Utilizing the Capabilities of the AWS Global Network at the Near Edge
When a client on the internet uses their browser to make a request for a URL to a server, more information that the URL itself is passed in the form of HTTP request headers. This includes information such as the name and version of the web browser (user-agent), the language the client prefers (accept-language), and […]
AWS regional edge – Utilizing the Capabilities of the AWS Global Network at the Near Edge
When you create a VPC and attach an internet gateway or NAT gateway, the AZs in the associated region need a mechanism to connect to the internet or other regions: Figure 8.2 – AWS regional transit centers This is why, in addition to the direct interconnects AZs have with each other, each region also has […]
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 […]
