In this episode of the AWS Developers Podcast, we discuss the Multi-Agent Orchestrator, an open-source framework designed to facilitate the orchestration of multiple AI agents. The conversation covers the challenges of building generative AI solutions, the need for specialized agents, and how the orchestrator functions as a smart router for directing user queries to the appropriate agents. They explore real-world use cases, including an e-commerce support system, and discuss the integration of new agents into the framework. The episode also compares the orchestrator with Amazon Bedrock's Converse API, highlighting the unique capabilities of the orchestrator in managing multiple agents.With Corneliu Croitoru, Prototyping Architects, AWS ; With Anthony Bernabeu, Prototyping Architects, AWSThe multi agent orchestratorUse case 1: From 'Bonjour' to 'Boarding Pass': Multilingual AI Chatbot for Flight ReservationsUse case 2: Beyond Auto-Replies: Building an AI-Powered E-commerce Support systemUse case 3: Speak Up, AI: Voicing Your Agents with Amazon Connect, Lex, and Bedrock

In this episode of the AWS Developers Podcast, Seb speaks with Peter Lavelle and Edward Sun about Twilio, and the complexities of authorization in cloud applications. They discuss the evolution of Twilio Flex, the challenges faced in implementing a sophisticated authorization model, and the decision-making process behind choosing between graph-based and policy-based authorization systems. The conversation also highlights the benefits of Amazon Verified Permissions (AVP) and the Cedar Policy Language, emphasizing the importance of decoupling authorization logic from business logic for better scalability and maintainability. This conversation delves into the implementation and benefits of AWS Verified Permissions (AVP) and the Cedar policy language. The speakers discuss the Quick Start experience for users, the challenges of policy-based systems, and the importance of automated reasoning in policy verification. They also explore metadata management, the flexibility of local versus central evaluation in authorization, and the implementation timeline for Twilio's use of AVP. The discussion highlights the growing adoption of these technologies and their potential future applications.With Peter Lavelle, Principal Software Engineer, Twilio ; With Edward Sun, Solution Architect, AWSTwilioGoogle ZanzibarAmazon Verified PermissionCedar: Learn about the language, tutorial and playgroundAWS blog: How we designed Cedar to be intuitive to use, fast, and safeAWS blog: Authorize API Gateway APIs using Amazon Verified Permissions

In this episode of the AWS Developers Podcast, Julian Wood hosts a discussion with Marc Brooker, a distinguished engineer involved in the creation of AWS Lambda. They explore the origins of Lambda, its evolution, and the impact of serverless technology on modern computing. The conversation delves into customer-centric innovations, the challenges of event-driven architectures, and the future of serverless in the context of generative AI. Mark reflects on the journey of Lambda, the lessons learned, and the exciting possibilities that lie ahead for serverless technology.With Marc Brooker, VP/Distinguished Engineer, AWS ; With Julian Wood, Developer Advocate, AWSAWS LambdaFirecracker microVMHow Lambda loads data from the block devices

In this conversation, Vadym Kazulkin discusses AWS Lambda Snap Start, a feature designed to reduce cold start latency for Java applications in AWS Lambda.

In this episode of the AWS Developers Podcast, the hosts discuss trusted identity propagation with Joseph De Clerck and Raphael Koike. Trusted identity propagation (TIP) allows organizations to propagate the actual user identity downstream to AWS services. It enhances IAM roles with the actual user identity, enabling fine-grained access control and simplifying IAM role management. The benefits of TIP include improved security posture, fine-grained access control, simplified user experience, and support for various OAuth 2.0 flows. Services that currently support TIP include Lake Formation, S3 Access Grants, Redshift Query Editor, EMR Studio, Athena, and Amazon QuickSight.With Joseph de Clerck, ProServ Consultant, AWS ; With Rafael Koike, Solution Architect, AWSIAM Identity CenterTrusted Identity PropagationIntegrate Tableau with Trusted Identity Center
