Revolutionizing Event Experiences: The AWS Summit Assistant Bot

Technology conferences and events serve as vital opportunities for innovation, knowledge sharing, and networking in the rapidly evolving technology industry. These gatherings range from large international conventions attracting tens of thousands of attendees to specialized conferences focused on sectors like AI, cybersecurity, or specific industries.

In this context, the AWS Communication Developer Services (CDS) team made headlines by integrating an AWS End User Messaging Social WhatsApp channel with Amazon Bedrock, marking the launch of the AWS Summit Assistant Bot during the AWS Dubai Summit 2025. This initiative is a textbook example of how technology can significantly enhance the experience of event attendees.

AWS Global Summits

AWS Global Summits have emerged as key events within the technology landscape, offering invaluable opportunities for professionals to explore the latest innovations in cloud computing. Each summit, hosted in major cities around the world, serves as a hub for developers, engineers, and business leaders, enabling knowledge sharing, networking, and hands-on engagement with AWS technologies.

These events typically feature keynotes from AWS executives and industry leaders, providing insights into future trends. Attendees can dive into technical sessions, workshops, and demos covering a broad spectrum of topics—ranging from artificial intelligence and machine learning (AI/ML) to serverless computing. The impact of these summits extends far beyond their duration, fostering a global community of cloud practitioners and driving innovation across various industries reliant on cloud technologies.

Attendee Experience Challenges

But even amidst such valuable opportunities, attendees often struggle to navigate these bustling events. Many find it challenging to pinpoint which sessions align with their interests and expertise. Locating specific areas within the venue—such as quiet rooms or lost and found—can also consume valuable time.

The reluctance to download single-use mobile apps adds another layer of complication. Factors like account creation, logins, storage issues, and app fatigue contribute to user pushback. Research by Storyly reveals that users devote 80% of their app time to their top three apps, often abandoning others rapidly. This trend is especially pronounced for event apps, as attendees prioritize immediate value, often opting out of cumbersome downloads that require time and effort. Such challenges can ultimately detract from the event experience, leading to missed opportunities for both learning and networking.

Enhancing the Attendee Experience

The AWS Summit Assistant Bot, launched during the AWS Dubai Summit in May 2025, provides a seamless solution to many of these attendee challenges. The process is simple: attendees can scan QR codes strategically placed throughout the venue to initiate a WhatsApp chat with the AI-powered assistant. This innovative solution employs advanced natural language processing capabilities to understand attendee interests and deliver tailored session recommendations.

Not only does the assistant offer real-time guidance to specific session locations, but it also directs users to various venue-specific areas, ensuring a smooth and efficient experience throughout the summit.

Solution Overview

To delve deeper into the AWS Summit Assistant Bot’s architecture is to explore how it seamlessly connects attendees with summit information systems. The design employs real-time processing of attendee messages and response generation, utilizing Amazon Bedrock Knowledge Bases to provide helpful and relevant answers.

The system architecture is modular and consists of four essential components that enhance message processing and analytics:

• Custom Metrics: Integration with Amazon CloudWatch allows for real-time monitoring through Amazon Simple Notification Service (SNS), tracking message delivery status and read receipts.

• Inbound Message Processing: This core functionality includes message validation filters for length and type constraints and manages session state while handling audio transcription workflows. Validated messages are published to a dedicated SNS topic.

• Response Generation: Here, Amazon Bedrock Knowledge Bases are utilized to intelligently manage messages, and the architecture is designed for future integration of alternative processing engines.

• Questions Categorization: This framework offers contextual analytics beyond standard CloudWatch insights and implements an Amazon DynamoDB categorization system that classifies and tracks inquiry patterns while ensuring privacy through PII-free analytics.

Technical Implementation

The AWS Summit Assistant Bot utilizes a serverless, event-driven architecture to manage WhatsApp message processing through a multi-stage workflow. When a message arrives via WhatsApp, the AWS End User Messaging service processes and publishes it to an SNS topic. These messages are then queued in Amazon Simple Queue Service (SQS) for systematic processing. Lambda functions execute the core business logic to manage interactions with DynamoDB and generate personalized user responses utilizing Amazon Bedrock.

Two parallel processes complement this message processing pipeline. The first is a categorization service, analyzing messages against existing DynamoDB categories, while the second handles custom CloudWatch metrics, tracking engagement for operational monitoring.

Generative AI Integration

The integration of generative AI within Amazon Bedrock introduces two core capabilities:

• A knowledge base retrieval system that employs OpenSearch vector embeddings alongside Anthropic’s Claude 3.7 Sonnet model for accurate information retrieval.

• A real-time message categorization engine dynamically classifying incoming messages and creating new categories based on content analysis.

Voice Message Processing

The bot also adeptly handles voice messages through a sophisticated processing chain. WhatsApp voice messages in the OGG format are processed via a Lambda-based conversion pipeline utilizing the ffmpeg library. These audio files are then transcribed using Whisper through the Amazon Bedrock Marketplace, chosen for its rapid processing and robust multi-language support.

Security and Privacy Considerations

A robust security-first approach simplifies the safeguarding processes within the architecture:

• Encryption measures using customer-managed keys protect data both at rest and in transit.

• Minimal PII CloudWatch logging alongside automatic data cleanup facilitated by DynamoDB’s TTL settings guarantees privacy.

• Implementation of Amazon Bedrock Guardrails helps prevent inappropriate content and the risk of data loss.

• Custom logic effectively mitigates resource draining by preventing large message ingestion and maintaining a concise conversation context window.

Monitoring and Analytics

Monitoring plays a dual role—ensuring operational efficiency while gaining insights into user inquiries. The solution utilizes several components:

• A real-time CloudWatch dashboard tracks vital metrics like message engagement and successful interactions.

• CloudWatch logs allow for granular analytics and insights into unique users and conversation volumes.

• Generative AI-powered categorization brings depth to understanding user queries, enhancing the overall effectiveness of the event experience.

By leveraging these AWS services and innovative solutions, the AWS Summit Assistant Bot showcases the transformative potential of technology in enhancing real-world event experiences. It’s a glimpse into how such frameworks can be adapted for various applications, from tech conferences to festivals and beyond.

Through these advancements, the intersection of technology and user experience becomes a powerful catalyst for change in today’s fast-paced digital landscape.
