Elasticsearch · OpenSearch · KibanaElasticsearch / OpenSearch, indexed, secured, sub-second.
In short: Elasticsearch is a distributed, document-oriented search and analytics engine built on Apache Lucene. It stores JSON documents in an inverted index for fast full-text search, log analytics, and observability at scale. Elasticsearch ships under the Elastic License 2.0 / SSPL (with AGPLv3 re-added in 2024), while OpenSearch is the Apache 2.0-licensed fork the community maintains after Elastic's 2021 licence change.

Search & analytics engineering
Specialized in both Elasticsearch and OpenSearch deployments for enterprise search and analytics.
Index & Shard Strategy
Optimize shard sizing, replica counts, and rollover policies (ILM/ISM) to prevent mappings explosion and split-brain.
Security & Role-Based Access
Implement fine-grained Document/Field level security plugins, RBAC, SAML integrations, and TLS encryption.
JVM & Garbage Collection Tuning
Prevent OutOfMemory (OOM) errors and long GC pauses by optimizing heap sizes and circuit breakers.
Query Profiling & Relevance
Improve search speed using query caching, avoiding costly wildcard/regex patterns, and tuning BM25 relevance.
Cross-Cluster Replication (CCR)
Design multi-region active-active architectures and snapshot-based disaster recovery strategies.
Log Analytics Hot/Warm/Cold
Implement multi-tier data architectures to dramatically reduce expensive ingest nodes and storage costs.

Active Shards
Always on. Cluster-engineered.
Dedicated master-eligible nodes, replica shards across availability zones, and cross-cluster replication - tested with failover drills. Engineered around a 99.99% search availability target, not a theoretical SLA.
A red-cluster P1, handled in under 15 minutes.
When unassigned shards turn the cluster red or a GC pause stalls ingest, a named search engineer responds - not a ticket queue. Shard reallocation and heap fixes applied online, with a blameless postmortem after.

Pre-Migration Assessment
SQL full-text / Solr → Elasticsearch 8
Estimated cutover window: < 15 minutes
Move to OpenSearch without the downtime
Elasticsearch → OpenSearch, or self-managed → Elastic Cloud. We pre-validate mappings and plugins, reindex or snapshot/restore, replicate live, and cut over with zero search downtime.

Elasticsearch & OpenSearch questions, answered
What Elasticsearch services do you provide?
We provide cluster architecture design, index lifecycle management, performance tuning, shard optimization, security configuration, log pipeline setup (Logstash, Beats, Fluentd), and migration services for Elasticsearch and OpenSearch.
How do you optimize Elasticsearch cluster performance?
We optimize through proper shard sizing, index lifecycle management, JVM heap tuning, bulk indexing optimization, search query caching, and hardware configuration. This typically delivers substantial performance improvements.
Do you support both self-hosted and Elastic Cloud?
Yes, we support self-hosted Elasticsearch, Elastic Cloud, AWS OpenSearch Service, and hybrid deployments. We help you choose the right deployment model based on your requirements and budget.
