        Centralized Logging Architecture

Figure 1: Centralized logging solution architecture on AWS

This solution includes an AWS CloudFormation template that you deploy in the primary account. This template launches an Amazon Elasticsearch Service (Amazon ES) domain, which is the hardware, software, and data exposed by Amazon ES endpoints. During initial configuration of the solution’s primary template, users choose from one of three solution sizes to determine the number and type of data nodes (Amazon ES instances) in the cluster: small, medium, or large. The primary template also provisions an Amazon Cognito user pool for Kibana dashboard user authentication.

The solution also includes a secondary template that you can deploy in secondary accounts or other AWS Regions. This template launches an AWS Lambda function that indexes logs from the secondary account or region on the Amazon ES domain in the primary account or region. During configuration of this template, you specify the Amazon ES domain endpoint and the Amazon Resource Name (ARN) of the primary AWS Identity and Access Management (IAM) role that the Lambda function will assume.

The centralized logging solution is designed to allow you to centralize the management of your own logs, but it also includes sample logs you can deploy for testing purposes. For more information, see Appendix A.
