Integrate Twilio with AWS
Connect Twilio directly to AWS Lambda, Amazon Bedrock, Amazon S3, and Redshift
Why Integrate Twilio with AWS?
Combining Twilio’s global network with AWS’s cloud infrastructure enables development teams to build, deploy, and scale intelligent communication workflows without managing servers or complex telephony setups.
Generative AI & Voice Agents: Connect real-time Twilio Media Streams and ConversationRelay to LLMs on Amazon Bedrock for automated conversational experiences.
Unified Customer Data: Stream real-time customer event signals from Twilio Segment directly into Amazon S3 data lakes and Redshift data warehouses for advanced analytics and Reverse ETL.
Serverless Scale: Process millions of inbound and outbound SMS, RCS, WhatsApp, voice, and customer data events asynchronously using Twilio and AWS Lambda, Amazon API Gateway, EventBridge, and more.
