OpenSearch Training and Certification Course

What is OpenSearch?

---

OpenSearch is an open-source search and analytics engine, originally derived from Elasticsearch, which was developed by Amazon Web Services (AWS) as part of the AWS Open Distro for Elasticsearch. It aims to provide users with a powerful and scalable solution for searching, analyzing, and visualizing large volumes of data in real-time. OpenSearch offers features such as full-text search capabilities, real-time analytics, geospatial data handling, and integration with various data sources and visualization tools. It is designed to be highly customizable and extensible, allowing developers to tailor it to their specific use cases and requirements. One of the key aspects of OpenSearch is its open-source nature, which means that its source code is freely available for anyone to use, modify, and distribute under open-source licenses. This fosters collaboration and innovation within the community, as developers can contribute enhancements, fixes, and new features to the project.

Why OpenSearch is important?

---

• Open-source alternative: It provides a free, community-driven alternative to potentially pricier search and analytics solutions. This makes data analysis accessible to a wider range of users and organizations.
• Flexibility and Customization: Being open-source, OpenSearch allows for greater flexibility and customization compared to closed-source options. You can modify it to fit your specific needs and integrate it with other open-source tools.
• Active development: Backed by a large community, OpenSearch benefits from ongoing development and improvement.
• Future-proofing: With the licensing changes around Elasticsearch, OpenSearch offers a more secure path for future development, avoiding potential restrictions associated with proprietary software.
• Cloud-agnostic: Unlike Elasticsearch offered by AWS, OpenSearch can be deployed on various cloud platforms or even on-premises, giving you more control over your data infrastructure.
