6 documented AWS OpenSearch cost inefficiencies, each with how to detect it and how to fix it.
AWS OpenSearchCER-0130
AWS Graviton processors are designed to deliver better price-performance than comparable Intel-based instances, often reducing cost by 20-30% at equivalent workload performance. OpenSearch domains running on older Intel-based families...
AWS OpenSearchCER-0147
Many legacy workloads still run on older Elasticsearch versions - such as 5.x, 6.0-6.7, or 7.1-7.8 - due to inertia, compatibility constraints, or lack of ownership. Once these versions exceed their standard support window, AWS begins...
AWS OpenSearchCER-0101
Domains running outdated OpenSearch versions - particularly Elasticsearch 1.5 through 7.8, OpenSearch 1.0-1.2, and OpenSearch 2.3-2.9, whose standard support ended on November 7, 2025 - begin to incur AWS Extended Support charges once they...
AWS OpenSearchCER-0367
OpenSearch Service managed domains are sized by choosing data node instance types and counts, optional dedicated master (cluster manager) nodes, and an EBS volume per data node. These choices are usually made from a peak ingest estimate or...
AWS OpenSearchCER-0368
Log, metrics and other time-series domains in OpenSearch Service typically write to a new index per day or per rollover, and most queries touch only the last few days. Without an Index State Management (ISM) policy, every older index stays...
AWS OpenSearchCER-0369
Production OpenSearch Service domains for search, logging and observability usually run around the clock with a stable node configuration for months or years. When none of that usage is covered by a commitment, every instance-hour is...
