Reduce costs and improve data management by storing infrequently accessed or historical data in the cold tier, maintaining efficient data retrieval.

Level of risk exposed if this best practice is not established: Low

Desired outcome: The cold tier storage option is used in Amazon OpenSearch Service to store and retrieve infrequently accessed or historical data efficiently, reducing costs while maintaining data availability.

Benefits of establishing this best practice:

  • Cost reduction: Using the cold tier storage option in Amazon OpenSearch Service helps reduce costs associated with storing and retrieving infrequently accessed or historical data.

  • Efficient data management: By using cold tier for infrequently accessed data, you can efficiently manage your data storage, making it easier to maintain data availability while minimizing storage expenses.

Implementation guidance

If you have data that must be preserved for compliance or regulatory reasons and or have historical value you can use cold tier to store such data at a lower cost than other storage tiers. cold storage is appropriate if you need to do periodic research or forensic analysis on your older data.

    • In the Cluster configuration section, look for the option Enable warm data nodes located in the Warm and cold data storage box.

      Note

      You need to have dedicated leader nodes in your domain to be able to use warm and cold storage.

    • Toggle on the option to enable UltraWarm nodes.

    • Select the Instance type.

    • Set the number of warm data nodes (required to have a minimum of three).
