External Elasticsearch and Kibana
Even though API Gateway has embedded Elasticsearch and Kibana, API Gateway provides an option to use external Elasticsearch and Kibana. The key points are as follows:
You can scale each of the component as per your need (as opposed to scaling the embedded bundle).
You can separate the analytics data from the API configuration data as per the recommended best practice.
You can improve the efficiency with the data backup or restore procedures.
It also caters to have different Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for each of the components. And so it helps in restoring API configuration data, which is much more important and tend to have aggressive RTO when compared to the analytics.
