# How to resolve Sprinto check for validating AWS load balancers' configuration

### About:

Sprinto check: AWS load balancer should have valid configuration

The above-mentioned Sprinto check verifies that you are using a load balancer within your AWS environment to distribute incoming traffic across multiple resources, such as EC2 instances, containers, or Lambda functions.

### Purpose:

This check ensures that your applications or services have a load-balancing mechanism to improve their availability, scalability, and fault tolerance. A load balancer distributes incoming traffic across multiple resources, reducing the risk of a single point of failure. Load balancers also provide features like health checks, session persistence, and SSL/TLS termination.

### How to fix this check:

Follow the below steps to resolve this check:

#### Before you begin

* Ensure you have administrator privilege to manage and configure AWS load-balancing services.

#### Configuring a Load Balancer

Note: The below procedure showcases how to review the load balancer for EC2 service. Similarly, review the use of load balancers on other services.

1. Log in to [AWS Console](https://aws.amazon.com/console/) using your credentials.
2. Navigate to the AWS EC2 service.
3. Click on Load Balancers from the left-side navigation bar.
4. Ensure that the currently configured load balancers meet the following conditions:
   * Each configured load balancer must be Active. If you have any inactive or dormant load balancers, delete them.
   * Every default action for a listener must have a target group assigned.

   * Each target group should be listed under the default action.

Sprinto will detect the presence of a configured load balancer and set the check status to "Passing.”
