Examples
You have a front-end and a back-end for your online application. While the back end manages dynamic requests like database queries and business logic, the front end offers static content like HTML, CSS, and JavaScript files. To load balance traffic between the front end and back end, you should employ an ALB. To route requests to various target groups according to the URL path, you should also utilize path-based routing. For instance, the front-end target group should get requests with the route /static/*, while the back-end target group should receive requests with the path /API/*. To do this, you must complete the following:
- Create an ALB and configure a listener on port 80 for HTTP traffic.
- Create two target groups, one for the front end and one for the back end, and register the EC2 instances or containers that run the front end and the back-end applications in the respective target groups.
- Create two rules for the listener, one for the path /static/* and one for the path /API/*, and associate each rule with the corresponding target group.
- Test the ALB by sending requests to the ALB’s DNS name and verifying that the requests are routed to the correct target group.
What Are AWS Load Balancer Types ?
Managing and allocating incoming network traffic is a critical component in the dynamic realm of cloud computing that helps to guarantee high availability and dependability for online applications. Load balancers from Amazon Web Services (AWS) offer a reliable solution. It’s critical to comprehend load balancers if you’re new to using AWS. The practice of load balancing divides incoming traffic among several servers or applications to maximize scalability, availability, and performance. AWS provides many load balancer types to meet various circumstances and demands. We will explore the idea of AWS load balancers in this post, going over terms, detailed procedures, diagrams, and examples to help you understand the basics.
