OpenSearch Consulting & Support for Enterprises

Our OpenSearch consulting covers cluster architecture and index design, ISM policy design, Security plugin configuration, performance tuning, AWS OpenSearch Service cost optimization, and migration planning. Every engagement is staffed by a named senior engineer with production OpenSearch experience, not a generalist treating it as interchangeable with Elasticsearch.

OpenSearch is the Apache 2.0 licensed fork created after Elastic changed its licensing in 2021, so it stays fully open source with no vendor lock-in on the license itself. It's also the native option if you're already on AWS OpenSearch Service. The tradeoff is that OpenSearch and Elasticsearch have diverged since the fork — plugin ecosystems, client libraries, and some API behavior no longer match exactly, which matters if you're migrating an existing Elasticsearch deployment.

Yes — this is the most common OpenSearch migration path we see, since 7.10.x was the last Apache 2.0 licensed Elasticsearch release before the fork. We assess client library compatibility, remap any plugins that don't have a direct OpenSearch equivalent, and validate query behavior before cutover, since some aggregation and scoring behavior has drifted between the two projects.

Instance sizing is the biggest lever — many domains are sized for peak ingest and never rightsized down. We review UltraWarm and cold storage tiering opportunities for older indices, evaluate reserved instance commitments against actual usage, and audit shard count against instance count, since over-sharded domains pay for capacity they don't use.

We configure fine-grained access control down to the index and field level, set up role mappings tied to your identity provider, and design tenant isolation for multi-team OpenSearch Dashboards access. Getting this wrong is a common source of either overly permissive access or dashboards that silently break for a subset of users.

A structured review of shard allocation and replication, Security plugin role mappings and audit logging, ISM policy coverage, and — for AWS-hosted domains — instance rightsizing. We deliver a written report with findings ranked by production risk. Most teams run this quarterly or before a major version upgrade.
