Cost optimization - Amazon OpenSearch Service Lens

Cost optimization

The cost optimization pillar focuses on avoiding unnecessary costs. Key topics include understanding spending over time and controlling fund allocation, selecting resources of the right type and quantity, and scaling to meet business needs without overspending.

Design principles

In addition to the design principles described in the AWS Well-Architected Framework Cost Optimization Pillar whitepaper, the OpenSearch Lens identifies the following design principles to facilitate good design in the cloud for your OpenSearch workloads.

These design principles can help you build and operate cost-aware OpenSearch Service domains that achieve business outcomes while minimizing costs and allowing your organization to maximize its return on investment.

  • Optimize instance type: Optimize instance type by using the right instance type for your OpenSearch domain, using the latest generation of instances, and employing the appropriate instance type for your OpenSearch workload.

  • Optimize storage tier: Configure storage tiers effectively by implementing hot, warm, and cold architectures in your OpenSearch domain. You can use different storage options including Amazon EBS volumes, instance store volumes, UltraWarm, OR1/OR2 instances and Zero-ETL Direct query S3 data.

  • Implement reserved instances: Use Reserved Instances for your OpenSearch domain to receive discounted pricing.

  • Monitor usage and cost: Actively monitor the usage and cost of your OpenSearch domain to estimate and reduce your service costs.
