Key Questions Answered
What is Edda and how does it work?
Edda is a service that polls AWS resources via AWS APIs and records the results, allowing users to quickly search through resources and see how they have changed over time. It is designed to handle dynamic cloud environments where resources are constantly changing.
How does Edda help in querying AWS resources?
Edda allows for dynamic querying of AWS resources using REST APIs, enabling users to search with specific criteria like instance IDs or public IP addresses. This is particularly useful as AWS APIs have limited querying capabilities.
What historical data features does Edda provide?
Edda stores historical data as versioned documents, allowing users to analyze past states of AWS resources and see changes over time. This is valuable for troubleshooting outages and understanding resource evolution.
What architecture does Edda use?
Edda is built as a Scala application that can run on a single instance or scale to multiple instances behind a load balancer for high availability. It uses MongoDB as its data store for persistence.
