GO-ing to production with Bedrock RAG Part 1

The way from a cool POC (proof of concept), like a walk in monets garden, to a production-ready application for an RAG (Retrieval Augmented Generation) application with Amazon Bedrock and Amazon Kendra is paved with some work. Let`s get our hands dirty. With streamlit and langchain, you can quickly build a cool POC. This two-part blog is about what comes after that.

Import existing resources into an AWS CloudFormation Stack

Presentation Deploying resources with infrastructure as code is the recommended way to provision resources in AWS. The native AWS-way of doing it is by using Cloudformation or CDK (Cloud Development Kit), and you should of course do this from day one. But in real world sometimes somebody provisioned resources via the console, or there is a need of refactor your code and split your stack into multiple stacks. Luckily It is not very often we have cases where it’s required to import resources.

Climb the (bed)rock with Python, Javascript and GO

Bedrock is now available in eu-central-1. It’s time to get real and use it in applications. Reading all blog posts about Bedrock, you might get the impression that Python and LangChain is the only way to do it. Quite the opposite! As Bedrock makes calling the models available as AWS API, all AWS SDKs are supported! This post shows how to use Bedrock with Python, Javascript and GO.

Handling Errors and Retries in StepFunctions

“Everything fails all the time” has been preached to us by Werner Vogels for a few years now. Every engineer working on building and maintaining systems knows this to be true. Distributed systems come with their own kind of challenges, and one of the AWS services that help deal with those is AWS Step Functions. AWS Step Functions allow you to describe workflows as JSON and will execute those workflows for you. In this blog, we’ll explore what happens when things inevitably go wrong and the options the service offers to perform error handling and retries using an example application.
