This video explores how to build a generative AI virtual assistant using Amazon Bedrock, Langchain, and Amazon ElastiCache. The presenters, Sashi Varanasi and Lakshmi Peri, discuss two key application patterns: chat history and messaging broker. They demonstrate how ElastiCache for Redis simplifies implementation by leveraging built-in Redis data structures, offering extreme low latency and versatility. The session covers the basics of generative AI, foundation models, and Amazon Bedrock, highlighting how ElastiCache can serve as an effective short-term memory solution for chatbots. A live demo showcases the integration of these technologies to create a context-aware, scalable virtual assistant.
