Amazon Bedrock + Promptfoo: Rethinking LLM Evaluation Methods

2026-02-02T19:55:22+00:00

I discovered something embarrasing about my LLM development workflow last month.  After spending hours crafting what I thought was the perfect prompt for a customer service chatbot on Amazon Bedrock, I deployed it and called it done. My validation process? I asked it five questions, nodded approvingly at the responses, and moved on. Sound familiar? This "vibe-based prompting" approach worked fine until the chatbot confidently told a user that our fictional company offers "24/7 phone support," a feature that never existed. The model hallucinated, and I had no automated way to catch it.  That experience sent me down a rabbit [...]

Understanding Security Groups and Network Access Control Lists (NACLs) in AWS

2024-08-26T09:31:42+00:00

Security within cloud environments is a critical consideration, and AWS offers robust tools to ensure that your cloud infrastructure remains secure. Two critical components in AWS for managing security are Security Groups and Network Access Control Lists (NACLs). These tools act as virtual firewalls, controlling the traffic that enters and exits your Virtual Private Cloud (VPC). While they serve similar purposes, they operate differently and are used in distinct scenarios to provide layered security. Security Groups: Instance-Level Security Security Groups in AWS are designed to control inbound and outbound traffic at the instance level. They are stateful, meaning that if [...]
