# Tipi di istanze supportati in Amazon OpenSearch Service
<a name="supported-instance-types"></a>

Amazon OpenSearch Service supporta i seguenti tipi di istanze. Non tutte le regioni supportano tutti i tipi di istanze. Per i dettagli sulla disponibilità, consulta i [prezzi OpenSearch di Amazon Service](https://aws.amazon.com/opensearch-service/pricing/).

Per informazioni su quale tipo di istanza è appropriato per il tuo caso d'uso, consulta [Dimensionamento dei domini Amazon OpenSearch Service](sizing-domains.md), [Quote delle dimensioni dei volumi EBS](limits.md#ebsresource) e [Quote di rete](limits.md#network-limits).

 Tieni presente che le seguenti famiglie di istanze non supportano i controlli di crittografia VPC: T2, T3, R3, I3, C4, M4, R4, C5, M5, R5, C6g, M6g, R6g e R6gd. VPC Encryption Controls è una funzionalità di sicurezza e conformità che ti offre un controllo autorevole centralizzato per monitorare lo stato di crittografia dei flussi di traffico, ti aiuta a identificare le risorse che consentono la comunicazione in chiaro e infine ti offre meccanismi per applicare la crittografia in transito all'interno e all'interno di una regione. VPCs Per ulteriori dettagli, consulta la documentazione dei [controlli di crittografia VPC](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-encryption-controls.html). 

## Tipi di istanza della generazione attuale

**Suggerimento**  
Consigliamo di utilizzare tipi di istanze differenti per [nodi principali dedicati](managedomains-dedicatedmasternodes.md) e nodi di dati.
