Lakehouse Meets GenAI: From Unified Observability to Autonomous Incident Resolution
The Problem: Modern platform infrastructure generates overwhelming observability data volumes that traditional systems struggle to efficiently store and analyze. This creates a critical gap between data collection and actionable insights, resulting in slower incident resolution and missed optimization opportunities.
The Solution: Platform leaders from a SaaS giant (Intuit) and an on-prem leader (Hitachi Vantara) demonstrate the powerful convergence of two game-changing open source technologies: modern Lakehouse architectures (Clickhouse, Apache Iceberg, Trino, Apache Arrow, Datafusion etc.) and GenAI-powered agents (LangGraph, Langfuse, Llama etc.). This integration creates a symbiotic system where optimized data structures enable intelligent agents to autonomously perform incident recovery and root cause analysis with speed and accuracy.
Non-Intrusive Multi-Tenant Auth & Authz with Istio, OAuth2Proxy, and OPA
Simplify authentication and authorization across applications, focusing solely on business logic while ensuring secure services.
Our solution features a multitenant proxy to streamline authentication on the SAAS platform. Istio service mesh intercepts every request, with a multitenant-aware proxy (enhanced OAuth2Proxy and caching) connecting to a centralized Identity Provider (IDP) for authentication. Post-authentication, the proxy collaborates with an authorization agent like OPA, passing context for dynamic policy evaluation.
Authentication and Authorization are decoupled from the code, allowing developers to use a centrally managed auth service. This shift lets development teams concentrate on business functions, leaving security rules to security analysts, saving time and resources.
Externalized authorization management offers runtime controls, including policy management, enforcement, and decision modeling for fine-grained access to applications, services, transactions and data.
Open Source Sovereign AI: Building Enterprise GenAI Platforms for Control & Compliance
As enterprises race to harness GenAI's transformative power, they're caught in a critical dilemma: innovate rapidly or sacrifice control? Commercial AI Model Providers offer convenience but demand a steep price—your data sovereignty.
What if you could have both cutting-edge capabilities and complete control?
In this session, we'll share our practical experiences building an enterprise-grade GenAI platform entirely with open-source components. We'll walk through our OSS architecture that integrates model serving (KServe, vLLM etc), orchestration tools, agentic frameworks, and no-code/low-code interfaces—delivering capabilities that meet enterprise needs while keeping sensitive data firmly behind your firewall.
Through real-world implementation example, we'll discuss what worked, what didn't, and the lessons learned along the way. You'll see how we addressed scaling, compliance, and performance challenges—all while maintaining full control of data and AI infrastructure. Our goal is to contribute these insights back to the community to help advance open-source enterprise AI adoption.
