How Gateway Load Balancers work
- Clients make requests to your application.
- The load balancer receives the request based on the route table configurations that are set within your VPC, Internet Gateway, or Transit Gateway.
- The load balancer routes requests to a target group consisting of a scalable fleet of appliances (for example, firewalls, deep packet inspection systems, URL filtering systems etc.) to process traffic flows.
- The virtual appliance processes the traffic, and forwards it back to the load balancer, or drops the traffic based on its configuration. This
- type of load balancer acts as a bump-in-the-wire between the source and destination.
- The load balancer forwards the traffic to its destination.
How To Configure GateWay Load Balancer In AWS ?
In the advanced landscape of cloud computing, managing incoming internet traffic efficiently is fundamental for ensuring the accessibility, scalability, and reliability of applications. AWS offers a set of services to address these necessities, and one such help is the Gateway Load Balancer (GWLB).
Gateway Load Balancer is an incredible tool intended to distribute incoming traffic across multiple targets inside an Amazon Virtual Private Cloud (VPC). Dissimilar to other load balancers like Application Load Balancer (ALB) or Network Load Balancer (NLB), which work at higher layers of the OSI model, Gateway Load Balancer has capabilities at the network (Layer 3) level.
Understanding how to configure and use the Gateway Load Balancer is significant for architects and administrators managing AWS infrastructure. In this guide, we will delve into the primary terminologies related to GWLB, provide a step-by-step process for design, offer models and clarifications for better perception, and address habitually posed inquiries to ensure complete comprehension of this fundamental AWS administration. We should investigate how Gateway Load Balancer can improve the presentation, scalability, and reliability of your applications hosted on AWS.
