Start a Free Trial Product featuresEnsure that your Amazon Elasticsearch (ES) clusters are using General Purpose SSD (gp2) data nodes instead of Provisioned IOPS SSD (io1) nodes for cost-effective storage that fits a broad range of workloads. Cloud Conformity recommends converting your io1 ES EBS nodes to gp2-type nodes in order to lower the cost of your monthly AWS bill while maintaining the I/O performance at the same level. For example, if your Elasticsearch application requirements are 150GB storage and 1000 IOPS (input/output operations per second) you can save roughly $68 per month using gp2 nodes instead of io1 nodes as an io1-type EBS data node with 1000 IOPS and 150GB storage costs $113.35/month while a gp2 node with 1000 IOPS and 335GB storage costs only $45.25/month (as of November 2016).
Using General Purpose SSD (gp2) data nodes instead of Provisioned IOPS SSD (io1) nodes represents a good strategy to cut down on Elasticsearch service storage costs because for gp2-type nodes you only pay for the storage compared to io1 nodes where you pay for both storage and I/O operations. Converting existing io1 resources to gp2 is often possible by configuring larger storage which gives higher baseline performance of IOPS for a lower cost. Note: The storage settings outlined in this conformity rule do not apply to dedicated master nodes provisioned within your AWS Elasticsearch clusters.
To determine the type of your existing Elasticsearch (ES) data nodes, perform the following:
