In this episode, we dive deep into AWS Builder Center, the new community platform designed to consolidate all AWS developer resources into one central hub. Roopal Jain, Software Development Engineer on the Builder Center team, explains how this platform brings together previously scattered AWS community properties like re:Post, Skill Builder, and community.aws into a unified experience for builders.

Beyond exploring what Builder Center offers - from articles and events to toolboxes organized by programming language - we take a technical deep dive into how the team built this large-scale web application. Rupal shares the architectural decisions behind their serverless microservices approach, the challenges of integrating Neptune graph database for social features like user following, and creative solutions for handling dual authentication methods in API Gateway.

The conversation reveals real-world implementation challenges that many developers face, from VPC networking complexities to service-to-service authentication patterns. We also discuss Builder ID, AWS's new individual identity system, and get a glimpse of what's coming next for the platform.

In this follow-up episode of the AWS Developers Podcast, we continue the conversation with Alex Huides, Principal Network Specialist Solutions Architect at AWS, focusing on Amazon VPC Lattice. We explore how developers can simplify networking concerns while maintaining robust connectivity between applications. Alex explains how VPC Lattice introduces a new boundary concept called service networks, which allows applications to communicate across accounts and VPCs regardless of IP overlap issues. The discussion covers how VPC Lattice abstracts away complex networking details, replacing traditional load balancers while providing secure, private connectivity between services. This episode demonstrates how AWS is removing undifferentiated heavy lifting in networking, making it easier for developers to focus on building applications.

In this episode, we dive deep into Moonpig's migration journey from an on-premise ASP.NET monolithic application to a fully serverless architecture on AWS. Richard Pearson, Head of Engineering, and Alexis Lowe, Principal Engineer at Moonpig, share their experience transforming a 25-year-old e-commerce platform. They discuss how they tackled the challenges of migrating from SQL Server to DynamoDB, implemented multi-region deployment, and achieved seamless scalability for their peak trading periods. Learn about their "no VPC" policy, their approach to observability, and how they organized their teams to embrace DevOps culture. This episode is particularly relevant for organizations considering a similar journey to serverless architecture or looking to scale their platforms globally.

Update Oct 25.: After we recorded this episode (July 10th 2025), AWS launched Amazon Bedrock AgentCore (that went in preview on July 16th, 2025) and generally available since Oct. 13rd, 2025. AgentCore is the recommanded solution to deploy your MCP agents on AWS. We keep this episode available as a learning experience but deploying MCP on Lambda is not the recommanded architecture for your production workloads.

In this episode, we dive deep into MCP (Model Context Protocol) servers on AWS Lambda. We explore what MCP is, how it enables AI systems to interact with tools through standardized protocols, and practical implementations on AWS Lambda. The discussion covers authentication mechanisms, deployment strategies, and the future potential of MCP servers as a marketplace for AI capabilities. Whether you're building AI-powered applications or interested in exposing your business capabilities to AI systems, this episode provides valuable insights into the technical aspects and business opportunities of MCP servers.
