How can I scale up an Amazon Elasticsearch Service (Amazon ES) domain?

Resolution

Before scaling up an Amazon ES domain, consider reducing the load on the domain. If it's not possible to reduce the load, use one or more of the following options to scale up:

Note: Amazon ES uses a blue/green deployment process when updating domains. This means that the number of nodes in the cluster might temporarily increase while your changes are applied. For more information, see About Configuration Changes.

After scaling up the domain, configure CloudWatch alarms to monitor resource utilization. For example, set an alarm that notifies you when CPUUtilization is above 80%.
