This article demonstrates how to deploy Amazon OpenSearch Serverless using Terraform infrastructure as code.

• OpenSearch Serverless provides search functionality without manual cluster management
• Terraform simplifies resource management through infrastructure as code approach
• Seven-step deployment process: initialize, create encryption policy, collection, network policy, VPC endpoint, data access policy, deploy
• Encryption policy uses AWS KMS to secure data at rest
• Network policy controls access via VPC endpoints or public internet
• Data access policy defines user permissions for collections and indexes
• VPC endpoint enables private access through AWS PrivateLink
• Terraform automatically manages resource dependencies
• Initial deployment may take over 10 minutes for first collection
• Use terraform destroy command to clean up resources and avoid costs

Terraform enables simplified management of OpenSearch Serverless infrastructure through declarative configuration and automated resource provisioning.
