Amazon OpenSearch Service now supports VPC egress for private connectivity to resources in your VPC
Amazon Web Services has introduced VPC egress support for Amazon OpenSearch Service, enabling domains within virtual private clouds to establish private network connections to internal resources without routing traffic through the public internet. The new capability allows OpenSearch domains to privately connect to machine learning models, AWS services, and custom applications by adding network interfaces to selected subnets and routing outbound traffic directly into the customer's VPC. Administrators can configure VPC egress through the OpenSearch Service console, AWS CLI, or programmatically via the CreateDomain and UpdateDomainConfig API operations. The feature is immediately available across all AWS regions where Amazon OpenSearch Service operates, addressing security and compliance requirements for organizations that need to maintain strict network isolation for their search and analytics workloads.
Why It Matters
This networking enhancement addresses a critical security gap for enterprise OpenSearch deployments by eliminating the need to expose internal traffic to the public internet when accessing VPC resources. The capability strengthens AWS's position in the enterprise search market by meeting strict compliance requirements for regulated industries and organizations with zero-trust network architectures.
