AI BriefingBuilding an EFK Stack on AWS OpenSearch
Key point
Oliveyoung built a logging system using AWS OpenSearch and the EFK Stack to ensure consistency and scalability for large-scale inventory data.
Details
Oliveyoung's Inventory Squad introduced the OpenSearch + EFK (FluentBit, Elasticsearch/OpenSearch, Kibana) stack to efficiently manage large-scale inventory change history that occurs at a minimum of ten million cases or more per day.
The reasons for building a separate system despite already using Datadog are as follows.
- Customization: Flexible log data configuration and analysis tailored to specific requirements
- Cost efficiency: Data lifecycle management and cost optimization through Index Lifecycle Management
- Scalability: Securing the potential to expand into a change history lookup API service through Rest API support
During the build process, the Firelens sidecar pattern was used in the AWS ECS Fargate environment. The FluentBit container was deployed as a sidecar, designed to identify only inventory-related logs among the app container's logs and route them to OpenSearch.
