AI Agents & What It Means for Cloud Architects

Over the past decade, we’ve moved from virtual machines → containers → serverless → event-driven systems . Now, we’re entering the next architectural wave: AI Agents . AI Agents— autonomous systems capable of reasoning, planning, and executing multi-step actions—are rapidly becoming the backbone of modern enterprise automation . But this shift is not only about AI models. It’s about how cloud architecture must evolve to support intelligence that executes real actions across distributed systems. This edition of Architecture Briefings explores what Cloud Architects need to know right now.     🔍 What Are AI Agents? Traditional AI → predicts or answers questions. AI Agents → think, plan, decide, execute, and iterate.

Agentic AI meets AWS - The future is here


 

Over the past year, AI has moved from simple prompts to fully autonomous agents capable of planning, reasoning, and executing multi-step tasks. This evolution—Agentic AI—is shaping the next generation of cloud architectures, and AWS is positioning itself right at the center of this shift.


🌐 What Is Agentic AI?


Agentic AI refers to AI systems that:

• Plan actions based on goals

• Retrieve information and tools needed

• Execute workflows independently

• Monitor and refine results

• Collaborate with other agents or humans


It’s no longer just “Give me an answer.”

It’s “Here’s my goal. You figure out the steps.”


Think of it as adding a brain + decision-making ability on top of LLMs.

🔥 What’s New From AWS in Agentic AI?


Amazon Agents for Bedrock

AWS recently introduced Amazon Agents, a framework that allows developers to build agentic applications using Bedrock foundation models.

These agents can:

• Interpret user queries

• Break down tasks

• Call AWS APIs

• Orchestrate workflows across services


All with secure, controlled access using IAM.


Example: An agent that automatically diagnoses CloudWatch alarm spikes, identifies root causes, and applies safe remediation steps — something SRE teams will love.


⸻


Managed Retrieval & Tool Use

Bedrock now supports:

• Retrieval-Augmented Generation (RAG) at scale

• Tool calling for AWS services

• Multi-step reasoning


This enables agents that can:

• Pull data from DynamoDB

• Summarize logs from S3

• Trigger Lambda functions

• Deploy resources with CloudFormation


With guardrails built in.


⸻


Agentic Workflows with Step Functions + LLMs

AWS Step Functions now integrates better with LLM outputs, allowing you to build:

• Autonomous troubleshooting flows

• Intelligent ETL pipelines

• AI-powered decision trees


This extends agent capabilities to production-grade workflows.


⸻


💡 Why Agentic AI Matters for Builders


As cloud workloads grow, engineering teams spend significant time on:

• Debugging

• Monitoring

• Deployments

• Compliance checks


Agentic AI can automate this heavy lifting.


Imagine:

• A DevOps agent that resolves 80% of recurring alarms

• A security agent that validates IAM policies and flags over-permissive access

• A commerce agent that updates prices based on demand and inventory

• A data agent that preps reports, dashboards, and insights automatically


This is not the future—it’s happening now.


⸻


🔍 Where You Can Start


Here are a few simple ways to explore Agentic AI on AWS:


✔️ Build a small Bedrock agent


Use Amazon Agents, give it a task like summarizing logs or automating tagging in S3.


✔️ Combine RAG + tool calling


Connect your internal data with Foundation Models.


✔️ Convert existing workflows to agentic


Pick any repetitive task → convert it into an agent-driven flow using Lambda/Step Functions.


✔️ Add guardrails


Use Bedrock Guardrails to ensure responsible and safe AI behavior.


⸻


🧭 Final Thoughts


We’re entering a new era where AI is no longer just a tool—it’s a teammate.

AWS is giving developers the building blocks to create autonomous systems that operate reliably and securely at scale.


If you’re building with AWS, this is the moment to start experimenting with Agentic AI. The earlier you adopt, the bigger the advantage.

JSON vs TOON: The Next Evolution of Data Interchange Formats

    Modern architectures rely heavily on structured data formats — and for over a decade, JSON has dominated APIs, logs, configuration, and event systems. But in 2025, a new format is gaining attention: TOON (Typed Object Oriented Notation) . TOON addresses some of JSON’s biggest limitations by introducing native types, schema predictability, compactness, and agent-friendly structure , making it highly suitable for AI-driven systems . Below is a simple visual explanation:   🆚 JSON vs TOON — Structure Comparison (Explained)     JSON Example { "name": "Ravi", "age": "30", "premiumUser": "false" } ❗ Data types are ambiguous → Everything is a string by default ❗ APIs must validate types manually ❗ Parsing is slow for AI agents that require precise types ❗ Less compact, not optimized for machine autonomy TOON Example { name: String("Ravi"), age: Int(30), premiumUser: Bool(false) } ✔ Explicit, strongly-type...

Advanced AWS Security in 2025: What’s New, and How to Use It

  Expanded Threat Detection with GuardDuty Extended Threat Detection AWS has significantly enhanced Amazon GuardDuty with Extended Threat Detection ( XTD ). This update brings new, powerful detection capabilities for highly sophisticated, multi-stage attacks — especially in containerized environments . • Container Protection for EKS: GuardDuty can now analyze EKS audit logs , runtime process data, and AWS API activity. This means it can flag complex attack patterns such as a privileged container being deployed, followed by persistence attempts, cryptomining , or reverse-shell activity .   • AI / ML-based Correlation: GuardDuty uses AI / machine learning to correlate disparate threat signals and present them as attack sequence findings. These findings come with MITRE ATT&CK mappings and remediation recommendations, making them more actionable.   • Protection Plans: There are advanced threat coverage plans for S3 , EKS, Lambda , EC2 , and more. ...
