**We’re excited to announce the first-ever OpenSearch Project Meetup in Namma Chennai! 🎉**

Join us for an engaging session where we’ll dive deep into the world of search, observability, security and AI Agents — and discover how OpenSearch is powering modern applications.

Whether you’re a developer, student, or tech enthusiast, this meetup is a great chance to learn, connect, and exchange ideas.

**📢 Agenda & Speakers:**

**1\. Vector DB 101 With Open Search**

**Speaker: [Ram Iyengar](https://www.linkedin.com/in/ram-iyengar/) \- Chief Evangelist at Cloud Foundry Foundation**

Building AI-powered applications requires more than just a model; it requires a robust retrieval strategy. This talk dives into OpenSearch’s native vector search capabilities, showing you how to turn a standard search engine into a powerful Vector Database.

We will cut through the noise and focus on implementation: how to generate, store, and retrieve vector embeddings right alongside your existing dataset. Whether you are building a Retrieval-Augmented Generation (RAG) chatbot, a semantic search engine, or a recommendation algorithm, you will leave this session understanding how to use OpenSearch to deploy efficient, scalable AI solutions without managing a new piece of infrastructure.

**2\. RAG in Action: Building Smarter AI Systems with OpenSearch**

**Speaker: [Madhavan Kidambi](https://www.linkedin.com/in/madhavan-kidambi-varadan/) \- Software Architect\, IBM**

A hands-on look at building production-ready RAG pipelines with OpenSearch. We’ll cover hybrid retrieval (BM25 + vector), metadata-aware search, relevance tuning, and end-to-end observability. See how OpenSearch solves many limitations of standalone vector databases and why it’s an ideal foundation for real-world RAG applications.

**3\. From AWS Elasticsearch to AWS OpenSearch — A Real\-World Journey of Scaling\, Sharding\, Stability and Cost Optimization**

**Speaker: [ManojKumar G](https://www.linkedin.com/in/manojkumar-g-27574a13/) and [Ragavendra Vigneshwaran](https://www.linkedin.com/in/ragavendra-vigneshwaran-r-61b265188/), Site Reliability Engineering Professional, IBM**

1\. Business Case & Migration Strategy: Inevitable shift from Elasticsearch 7\.10 to OpenSearch 2\.15 to avoid end\-of\-support risks\, phase\-wise zero\-downtime upgrades \(inline\, blue\-green\, parallel\, snapshot\+inline\) across environments\.

2\. Achieving SLA & Cost Goals: Maintained zero downtime and SLA during migration; optimised costs via shard reallocation\, node reduction\, and static index templates\.

3\. OpenSearch Storage & Performance Tuning: Migrated ILM to ISM with size/age\-based rollover policies; resolved Fluentd backpressure data loss via S3 → SQS → Vector\.dev buffer\, enabling zero log loss and further node consolidation\.

4\. Serverless Adoption: Introduced AWS OpenSearch Serverless with blue\-green deployment for additional cost optimization and scalability\.
