This tutorial demonstrates how to collect your AWS Elastic Load Balancers, Application Load Balancers, and Network Load Balancers using [Elastic Load Balancing](https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/what-is-load-balancing.html). The data, decrypted and retaining original timestamps, is sent to Coralogix. The process is installation-free and entails simply deploying a Lambda function.
Once ingested by Coralogix, view and analyze your logs on our platform using queries, alerts, visualizations, and ML capabilities.
## Prerequisites[](#prerequisites "Direct link to Prerequisites")
* AWS account with permissions to create Lambdas and IAM roles
* An operating load balancer that writes its access log to S3
* An S3 bucket clear of any triggers and with a policy that grants the load balancer permission to write access logs to the bucket
## Installation[](#installation "Direct link to Installation")
**STEP 1**. Navigate to [Coralogix Lambda creation](https://coralogix.com/docs/external/coralogix-aws-shipper/#amazon-s3-cloudtrail-vpc-flow-logs-and-more).
**STEP 2**. Fill in the required parameters.
**STEP 3**. Check the checkbox: "I acknowledge that this app creates custom IAM roles and resource policies."
**STEP 4**. Deploy.
