Building an Agentic App Deployer with Amazon Bedrock and AWS Lambda

PDI Technologies, a company serving convenience retail and petroleum wholesale industries, developed PDI Brew to address the long tail of internal tools that never get built due to traditional deployment pipelines. PDI Brew allows non-technical employees to describe a tool in plain English and receive a fully provisioned, multi-tenant web application on AWS within seconds, complete with single sign-on (SSO) and no need for Git, terminals, or DevOps knowledge. The architecture separates planning and provisioning: a planning agent captures user intent and emits a structured deploy manifest, while a provisioning agent on AWS Lambda decomposes that manifest, classifies the workload, selects tools, and orchestrates creation of all downstream AWS resources. The planner is pluggable, with two paths: a Vibe App Builder skill that runs inside an existing AI assistant like Claude or ChatGPT, or an Amazon Bedrock invocation within the AWS trust boundary. The provisioning agent uses AWS SDK and Microsoft Graph APIs, handles long-running steps via asynchronous self-invocation, and classifies apps as static or full-stack. Apps run on a dual-tier compute model: shared CRUD Lambda for most, and per-app Lambda with scoped IAM only for those needing specific capabilities, gated by admin approval. In-app AI features are provided through a governed gateway to Amazon Bedrock, with guardrails, quotas, and audit trail, never exposing model keys to app authors.
