Abstract: Systems and techniques are described herein for tiered storage of customer data accessed by a search service of a computing resource service provider. In some aspects, customer data may be received by a search instance executed across a plurality of compute nodes and provisioned by a search service. The customer data may be indexed and the data and resulting index may be stored locally by a first pool of hot compute nodes of the search instance. The customer data and index may be migrated and stored remotely by a data storage service. Metadata associated with the customer data and/or index may be stored in a second pool of warm compute nodes of the search instance. The warm compute nodes, upon receiving a request to access the customer data, may identify a location of the customer data and retrieve the customer data from the data storage service according to the metadata.
