AWS re:Invent is massive and full of opportunities. I share practical tips from two years of experience as both speaker and attendee —this post helps you plan smart, learn deeply, and connect with the AWS community like a pro. www.ranthebuilder.cloud/post/guide-t...

🚀 Had a great time with Giuseppe Battista on the AWS Startups Twitch stream! We explored building serverless MCP servers on AWS— how to make it as production-grade as possible (within reason 😄). www.youtube.com/watch?v=JuB4...

🚀 Excited to join forces with Giuseppe Battista on the AWS Startups Twitch stream next Tuesday, July 22nd, at 2 PM BST! We’ll explore building Lambda based MCP servers on AWS—what works, what breaks, and how to make it as production-grade as possible (within reason 😄). Join: bit.ly/basup-twitch

Getting started with AWS Lambda is easy—securing it isn’t. I wrote a practical guide to help you build secure serverless apps from day one. ✅ Input validation ✅ Least privilege IAM ✅ Secrets, caching, observability & more www.ranthebuilder.cloud/post/14-aws-... #AWS #Serverless

AWS Lambda handler cookbook 7.1.0 is out! - DevEx update: run 'make update-deps,' which updates the CDK version to the latest version and also all Python dependencies. I'm surprised I didn't implement this sooner! github.com/ran-isenberg...

🔥 Agentic AI is moving fast—are your guardrails keeping up? Platform teams must lead adoption by wrapping Agentic AI & MCP with secure, scalable foundations. New blog post → Foundations, CLI, prompt libraries, & real patterns. www.ranthebuilder.cloud/post/agentic... #PlatformEngineering #MCP #DevE

🎉 1,000+ subscribers! I share real-world lessons from the front lines: 🧠 Using AI for architectural design, not just code ⚙️ Scaling platforms for 1,000+ developers ☁️ Building production-ready serverless services with security, observability, and governance baked in www.linkedin.com/newsletters/...

🚨 I tried running an MCP server on AWS Lambda. Spoiler: It ran—but not before it crawled, cried, and cold-started for 5 seconds. 🐢🔥 I break down what worked, what didn't, and why the current developer experience is bad www.linkedin.com/posts/ranbui...?

Check out the latest article in my newsletter: Build Serverless WebSockets with AWS AppSync Events and Powertools for AWS Lambda www.linkedin.com/pulse/build-... via @LinkedIn

🧠 Real-time apps just got easier with AppSync Events, Lambda, and Powertools for AWS Lambda! Build a serverless WebSocket API with CDK, direct event handling, and full observability. Check out my blog post for full code and first impressions! www.ranthebuilder.cloud/post/aws-app...

LOVE this! Mostly lots of pros with just one con: "Yes. When you select S3 or Firehose, the logs won't be stored in CloudWatch Logs and you will pay a lower price for delivery to S3/Firehose. You don't need to add any IAM deny statement." >> aws.amazon.com/blogs/comput...

I'm conflicted about this. I don't like paying of all of a sudden for something I didn't before, plus some of it is AWS controlled. Luckily, I have a blog post that will help you: aws.amazon.com/blogs/comput... www.ranthebuilder.cloud/post/is-aws-...

✨ AWS Powertools for Python v3.11.0 brings first-class support for AppSync Events! I need to get my hands dirty with it :) Read more: github.com/aws-powertoo...

🐷💻 MCP, Serverless Agentic AI… and Peppa Pig? You read that right. In a hilarious + technical guest post, Anton Aleksandrov builds a stateless MCP server on Lambda, books Peppa Pig tix with OINK-GPT, and drops a GitHub repo. #Serverless #MCP #AI #AWS www.ranthebuilder.cloud/post/buildin...

Issue #325 of Off-by-none is out! In this issue, AWS introduces a new Well-Architected #GenAI Lens, Amazon Q Developer launches a new agent, and Serverless Inc. joins the MCP party. #offbynone offbynone.io/issues/325/

🧠 Unpopular opinion: Not everything needs to be agentic AI. I've seen too many systems use agents just because. Often, "boring" code works better—simpler, cheaper, and maintainable. Solve the problem first. Choose the tech second. Not every solution needs to brag. #AI #Architecture

In the last 4 months since speaking at re:Invent with @julianwood.com , a lot has happened: ✅ Launched a LinkedIn newsletter ✅ Started consulting ✅ Blogging at ranthebuilder.cloud ✅ Serverless & platform eng focus ✅ Conference talks 👉 Follow for more! #Serverless #AWS

Powertools for AWS Lambda 3.10.0 is out with new AppSync resolver Pydantic models for the parser utility, which makes input validations easier! Want to learn more about input validation best practices for Lambda? Check out my blog post: www.ranthebuilder.cloud/post/aws-lam... #AWS #Serverless

Has your platform engineering team ever built internal tools nobody used? In my latest post, I share practical strategies to boost adoption, enhance DevX, and build tools developers actually want! www.ranthebuilder.cloud/post/platfor... #PlatformEngineering #InternalTools #DevEx #AWS

A must read, as always

🚀 Reduce AWS Lambda logging costs without losing visibility! Powertools for AWS Lambda Python Logger buffers logs (DEBUG/INFO), flushing them only when errors occur. docs.powertools.aws.dev/lambda/pytho... #AWS #Serverless #Lambda #CloudWatch #CostOptimization

We often resort to complicated solutions—like pre-signed URLs—to address payload size limitations in serverless applications. But AWS just published a fantastic article reminding us of a simpler, more efficient approach: using compressed payloads. aws.amazon.com/blogs/comput...

AppSync Events just got better! publish either via websocket or HTTP aws.amazon.com/blogs/mobile...
