OpenAI Comes to Amazon Bedrock: A Win for Model Consumers

2026-04-30 AWS Timothy Patterson

In a move that few would have predicted even a year ago, Amazon Web Services and OpenAI have announced a significant partnership that brings OpenAI’s frontier models — including Codex — directly into Amazon Bedrock. For those of us who build on AWS and care about where the AI ecosystem is headed, this is a genuinely exciting development.

You can read the official announcements from both sides here: OpenAI on AWS and AWS: Bedrock OpenAI Models .

Amazon Bedrock's Security Model: What Enterprises Actually Need to Know

One of the most common blockers I hear from enterprise teams evaluating generative AI isn’t about model quality — it’s about trust. Where does our data go? Can AWS see our prompts? Will our inputs be used to train someone else’s model? Can we meet our compliance requirements? These are the right questions to ask, and Amazon Bedrock has spent considerable engineering effort making sure the answers are satisfying.

This post walks through the core pillars of Bedrock’s security model: how inference stays private, what AWS commits to around your data, how to keep traffic off the public internet, what compliance certifications are in place, how IAM gives you fine-grained access control, and how AgentCore’s Cedar policies extend that control to the level of individual agent tool calls.

Amazon Bedrock AgentCore: The Infrastructure Layer Your AI Agents Have Been Missing

Building an AI agent that works in a demo is one thing. Getting it to reliably work in production — across thousands of concurrent users, with proper security, memory, and observability — is an entirely different challenge. If you’ve ever tried to take an AI agent from prototype to production, you know exactly what I’m talking about. Months of undifferentiated infrastructure work: session management, identity controls, persistent memory, tool integrations, monitoring. All of it built from scratch, all of it before you’ve written a single line of your actual business logic.

The Evolution of AI: From Monolithic to Task Specific Models

2024-03-05 AWS Timothy Patterson

The field of artificial intelligence (AI) has been rapidly evolving, with new advancements and breakthroughs happening at an unprecedented pace. One of the most significant trends we’ve recently observed is the shift from monolithic, all-encompassing AI models to more specialized, task-specific models. This shift mirrors the historical trend in software development, where we moved from monolithic applications to microservices-based architectures.

From Monolithic to Microservices

In the past, software applications were often built as monolithic structures, where a single application would handle all the functionality and features. While this approach had its advantages, such as simplicity and ease of deployment, it also had significant drawbacks. Monolithic applications were often difficult to scale, maintain, and update, and a single failure could bring down the entire system.

Cultivating the Garden of Data With AWS DataZone

2023-10-11 AWS Timothy Patterson

I have said it many times before, “Data is the new seed of innovation.”

Data as the seed of innovation.

Data stands as the foundational seed from which innovation sprouts, but how we manage and nurture this data determines whether we cultivate a thriving garden of insights or merely a compost heap of unsorted information. Enter Amazon DataZone.

What is Amazon DataZone?

Amazon DataZone is a data management service designed to streamline the process of cataloging, discovering, governing, sharing, and analyzing data. It acts as a centralized hub, allowing users to share and access data across accounts and supported regions. This service integrates seamlessly with various AWS services, including (but not limited to) Amazon Redshift, Amazon Athena, AWS Glue, and AWS Lake Formation.

Prompt Engineering with AI: The Art of Asking for What You Want

2023-10-09 AWS Timothy Patterson

In the world of sales, one principle has stood the test of time: the importance of asking for what you want. Whether it’s nudging a prospect towards a deal or clarifying a client’s needs, the clarity of one’s ask can make or break the outcome. Interestingly, the same logic applies in the realm of AI, particularly in the emerging discipline of Prompt Engineering.

What is Prompt Engineering?

At its core, prompt engineering is the science and art of designing effective prompts to guide AI models, specifically language models, to produce desired outputs. It’s akin to finding the right way to ask a question to obtain the most useful answer. Given the vastness of knowledge and patterns an AI model (like Anthropic’s Claude v2) can recognize, how you ask something significantly influences the information you retrieve.
