OpenSearch, indexed, secured, observable.
In short: OpenSearch is a community-driven, Apache 2.0-licensed open-source search and analytics engine forked from Elasticsearch 7.10.2 by AWS. Built on Apache Lucene, it provides full-text search, log analytics, and observability with built-in security, alerting, and SQL support across distributed clusters.
OpenSearch consulting for cluster architecture, Elasticsearch migration, performance optimization, enterprise security, and AWS OpenSearch Service operations, with recommendations tied to measured workload evidence.

Active Shards
Resilient by design. Cluster-engineered.
Dedicated cluster-manager nodes, replica shards across availability zones, and cross-cluster replication support availability objectives that are tested with failover drills, measured recovery times, and verified restore procedures.

When unassigned shards turn the cluster red or a GC pause stalls ingest, a named OpenSearch engineer responds - not a ticket queue. The response plan covers shard-allocation evidence, staged remediation, rollback criteria, and a blameless postmortem under the contracted response target.

Pre-Migration Assessment
Elasticsearch → OpenSearch / Amazon OpenSearch
Estimated cutover window: < 15 minutes
Move to OpenSearch with a controlled cutover
Elasticsearch → OpenSearch, or self-managed → AWS OpenSearch Service. We assess the cluster, test compatibility, snapshot-migrate data and plugins, validate in parallel, reconcile source and target, and cut over with documented rollback criteria.

OpenSearch FAQs: migration, AWS Service, tuning & security
Common questions about our OpenSearch managed services
What's the difference between OpenSearch and Elasticsearch?
OpenSearch is a community-driven, open-source fork of Elasticsearch 7.10.2, created by AWS after Elastic changed its licensing. OpenSearch uses the Apache 2.0 license and includes features such as security, alerting, and SQL support. The projects have diverged, so API, plugin, mapping, and client compatibility must be checked against the specific source and target versions.
How do you migrate from Elasticsearch to OpenSearch?
Our migration process includes source assessment, version and plugin compatibility testing, snapshot-based migration, configuration mapping, application updates, and parallel-run validation. Record counts, checksums, representative queries, and rollback gates are verified before cutover; the interruption window depends on the source topology and application constraints.
Can you help with AWS OpenSearch Service?
Yes, we specialize in AWS OpenSearch Service including cluster sizing, VPC configuration, fine-grained access control, SAML authentication, UltraWarm and cold storage optimization, and cross-region replication. We help you leverage AWS-managed features while optimizing costs.
What's your approach to OpenSearch performance tuning?
We baseline indexing throughput, search latency, concurrency, heap pressure, and shard behavior before changing shard sizing, lifecycle policies, JVM settings, bulk ingestion, caches, or analyzers. Each change is tested against representative queries and data, so the measured improvement is specific to the workload rather than a promised multiplier.
How do you handle OpenSearch security?
We implement comprehensive security including TLS encryption, role-based access control (RBAC), field-level and document-level security, SAML/OIDC integration, audit logging, and compliance configurations for GDPR, HIPAA, and SOC 2 requirements.
What monitoring do you provide for OpenSearch?
We set up comprehensive monitoring using OpenSearch's built-in tools, Prometheus, and Grafana. This includes cluster health, node metrics, index performance, search latency, ingestion rates, and custom alerting for proactive issue resolution.
