The two leading search engine technologies, Elasticsearch and OpenSearch, are both top-notch options. However, when it comes to choosing the right one for your business, making a decision without comparing them on various aspects is tough. That's why we've done the comparison for you!
Aspect | Elasticsearch | OpenSearch | Which One to Choose? |
Origin & Licensing | Developed by Elastic. License changed to SSPL (2021). | Forked from Elasticsearch by Amazon. Fully open-source under Apache 2.0. | Both Elastic and Opensearch have opensource license available |
Performance & Speed | High-speed real-time search and analytics. Built on Apache Lucene. | Mirrors Elasticsearch in speed and performance. Built on Apache Lucene. | Both are equally fast and efficient. |
Ecosystem | Mature ecosystem with tools like Kibana, Beats, Logstash. | Growing ecosystem with OpenSearch Dashboards and similar tools. | Elasticsearch offers a more feature-rich ecosystem. |
Scalability | Easily scalable, designed for distributed environments. | Same scalability, with sharding and replication support. | No difference—both are highly scalable. |
Cost & Licensing | SSPL restricts cloud use cases. | Open-source Apache 2.0, with more flexibility for cloud. | OpenSearch is better for fully open-source, cloud-native deployments. |
AWS Integration | Runs on AWS but lacks native integration. | Seamlessly integrated with AWS for managed services. | OpenSearch is the best choice for AWS users. |
AI & Machine Learning | Advanced machine learning features like anomaly detection. | Basic machine learning, still catching up to Elasticsearch. | Elasticsearch leads in AI and machine learning capabilities. |
Community & Support | Larger community with extensive support from Elastic. | Growing community, backed by Amazon. | Elasticsearch has a more established community, but OpenSearch is growing rapidly. |
Security Features | Advanced security features with premium options for RBAC, encryption, and auditing. | Robust security features included in the open-source version, no premium tiers required. | OpenSearch offers strong security for free, while Elasticsearch may require premium features. |
Deployment Options | Offers flexibility with both on-premise and cloud deployments. Managed Elasticsearch is available via Elastic Cloud. | Designed for cloud-native environments, tightly integrated with AWS for managed deployment. | Choose Elasticsearch for hybrid environments, OpenSearch for cloud-native use cases. |
Monitoring & Logging | Offers advanced logging and monitoring via Elastic Stack (Elasticsearch, Logstash, Kibana). | Provides monitoring with OpenSearch Dashboards and similar ingestion tools. | Elastic Stack is more mature, but OpenSearch offers similar capabilities. |
Upgrades & Maintenance | Elastic provides regular updates with new features, but upgrades can be complex. | OpenSearch receives consistent updates from AWS, typically focused on cloud improvements. | OpenSearch may be easier to maintain, especially in AWS environments. |
Commercial Add-Ons | Offers a variety of commercial add-ons for monitoring, security, and machine learning. | OpenSearch offers most features in open-source form, with fewer commercial dependencies. | If you need advanced, enterprise-grade features, Elasticsearch's add-ons may be necessary. |
Data Visualization | Kibana provides advanced dashboards and visualizations, widely used in analytics. | OpenSearch Dashboards offer comparable data visualization tools, closely mirroring Kibana. | Elasticsearch has more mature visualization tools, though OpenSearch Dashboards is catching up. |
Data Ingestion Tools | Supports data ingestion via Beats and Logstash, with advanced capabilities. | OpenSearch has similar ingestion tools but lacks the full maturity of Logstash/Beats. | Elasticsearch is better for complex data ingestion needs. |
With this comparison chart, you can see that Elasticsearch delivers exceptional performance for most use cases. Therefore, we conclude that Elasticsearch is the best solution for critical business applications.
