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 their licensing. OpenSearch maintains Apache 2.0 licensing and includes features like security, alerting, and SQL support built-in. Both are compatible with the Elasticsearch API, but OpenSearch has diverged with its own roadmap and features.
How do you migrate from Elasticsearch to OpenSearch?
Our migration process includes assessment of your current Elasticsearch cluster, compatibility testing, snapshot-based data migration, plugin and configuration migration, application connection string updates, and parallel running validation. We ensure zero data loss and minimal downtime during the transition.
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 optimize shard sizing and distribution, implement proper index lifecycle management, tune JVM heap settings, optimize bulk indexing throughput, configure search query caching, and implement custom analyzers for your use case. We typically achieve 2-10x performance improvements.
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.
