A common oversight is the failure to enable slow logs for search and indexing operations. This critical configuration gap leaves teams blind to the root causes […]

Overview In the AWS ecosystem, managing costs for stateful services like Amazon OpenSearch is a critical FinOps discipline. While On-Demand instances offer flexibility, they come at a premium price. For stable, long-running workloads, leveraging Amazon OpenSearch Reserved Instances (RIs) is essential for unlocking significant savings.
