Gateway Load Balancer
Explore how Gateway Load Balancers function at the network layer to maintain and scale virtual appliances like intrusion detection systems. Understand their role as gateways distributing traffic, the use of listeners and target groups configured with the GENEVE protocol, and deployment of private connections via GLB endpoints. This lesson helps you grasp key concepts for designing highly available and scalable AWS architectures.
We'll cover the following...
Gateway Load Balancers (GLB) operate on the network layer, the third layer of the OSI model, and allow us to maintain, scale, and deploy third-party virtual appliances such as intrusion detection systems. A virtual appliance is a software package that includes an operating system, application software, and virtual hardware configuration required to run a virtual machine platform.
These load balancers act as a gateway (a single point of entry and exit) and distribute incoming traffic across multiple appliances, scaling them up or down according to our ...
