The fix: stop trusting one region. The suite now runs in every commercial region and scores each engine against the one it matches best.
Eight engines, tracked run over run: https://paritysuite.org #dynamodb #aws

Stop losing Terraform state files. Store them in S3 with DynamoDB locking to prevent concurrent modifications and enable team collaboration. Server-side encryption keeps data safe. #terraform #s3 #dynamodb

Dynoxide 0.11.3 is out.
An old issue I logged to investigate a Windows socket option for TIME_WAIT parity with Unix. The parity already existed - the actual gap was that a plain Windows bind can be hijacked by another same-user process using SO_REUSEADDR. Both listeners now bind with SO_EXCLUSIVEADDRUSE.
Bonus: the test suite now runs on Windows in CI for the first time, and immediately caught two tests that assumed Unix semantics.

Someone asked a good question on my DynamoDB conformance suite: does a conditional write inside a transaction cost read capacity on top of the write?
The AWS docs aren't clear, so I ran it against real DynamoDB. A passing condition adds nothing; an idempotent replay flips the bill from write to read.
That's one strand of the latest release. Next, 2.0.0 takes on DynamoDB's regional differences and how to score them fairly. #dynamodb #aws #database #serverless

accesspatterns.dev runs a DynamoDB engine in the browser tab, with nothing behind it. That's dynoxide 0.11, compiled to WebAssembly. The how: https://martinhicks.dev/articles/introducing-accesspatterns-dev

DynamoDB is one of my favourite databases, but it can be one of the harder ones to learn - it doesn't reward the instincts you bring from SQL.
So I built accesspatterns.dev: a real DynamoDB-compatible engine running in a browser tab, on dynoxide compiled to WebAssembly. A guided course, a library of access-pattern models, and a full console - learn it by running it.
It's an early preview. I'd like that model library to become a shared catalogue of how people really model DynamoDB, not just my handful. No account, nothing to install.

🔄 On deployment, the same APIs map automatically to real AWS services like #Lambda, #DynamoDB, #Aurora, #APIGateway & #Bedrock — with zero code changes
🤖 The standout feature: the framework ships with built-in rules and steering files for #AIagents, so they automatically apply clean architecture and best practices
🔗 End-to-end typing works without code generation and supports frontends like Next.js, Nuxt, Astro, Angular, React, Vue & Svelte — plus mobile apps in Swift, Kotlin & Flutter

Dynoxide 0.10.0 is out, the biggest release since the original engine.
The headline: the same DynamoDB engine now runs in the browser. WebAssembly + wa-sqlite over OPFS, no server, no cross-origin isolation headers. CRUD, GSI and LSI queries, fully client-side. A preview for now.
Also: an official ~5 MB Docker image, a drop-in for amazon/dynamodb-local.
Heads-up: first breaking release. MCP over HTTP now needs a bearer token.

Open-source DynamoDB emulators are closing on the real thing fast. Floci's gone from ~61% to the low 90s in a month. ExtendDB landed near the top from a standing start.
Wrote it up after yesterday's site launch: https://martinhicks.dev/articles/dynamodb-conformance-org
684 tests, all scored against live AWS DynamoDB.

My DynamoDB conformance suite has a proper home now: https://dynamodb-conformance.org
Eight emulators. 684 tests. One independent suite scoring all of them against DynamoDB's real-world behaviour.
Runs weekly. Matrix, run history, per-target pages. Every figure pulled straight from each run.

I am creating some integration tests for my apps backend.
The tests are checking whether my data structure is correctly passed to #DynamoDB.
With the help of TestScoping I can prepare and teardown my local instance without bloating up my test code.

AWS US-EAST-1 outage (Oct 20, 2025): Root cause & lessons
A DNS race condition in DynamoDB led to empty endpoint records, triggering cascading failures across AWS services like EC2 and Lambda.

I've open sourced a DynamoDB engine in Rust, backed by SQLite. ~3 MB, 15ms startup, 526 conformance tests against real DynamoDB. No JVM, no Docker. More at https://dynoxide.dev
It started as infrastructure for Nubo, a native DynamoDB client we're building at Si Novi - https://nubo.sinovi.uk

AWS has 200+ services. Most companies use about 15. The same ones show up in every project: EC2, S3, Lambda, RDS, DynamoDB, API Gateway, CloudFront, SQS, SNS, CloudWatch.
That handles 80% of everything. Wrote a guide covering just the ones that matter.#aws #cloud #infrastructure #EC2 #IAM #S3 #RDS #DynamoDB #Lambda #APIGateway #CloudFront #Route53 #SQS #SNS #CloudWatch #EKS #CDN

AWS-Ausfall im Nahen Osten: Rechenzentrumsvorfall legt Cloud-Dienste in UAE und Bahrain lahm
Der Ausfall weitete sich rasch auf das gesamte Dienstportfolio in der Region aus. In ME-CENTRAL-1 waren nach AWS-Angaben mehr als 38 Cloud-Dienste beeinträchtigt, darunter AWS Lambda, Amazon Elastic Kubernetes Service (EKS), Amazon Virtual Private Cloud (VPC) sowie die Datenbankdienste RDS und DynamoDB.

Очень странные дела или подключаем YDB в AWS NoSQL Workbench
При работе с Yandex Database (YDB) часто возникает потребность в удобном визуальном инструменте для работы с данными. AWS NoSQL Workbench — популярное приложение для моделирования и тестирования NoSQL баз можно использовать и с YDB благодаря DynamoDB-совместимому Document API.

Bài viết hướng dẫn xây dựng hệ thống giám sát IoT không máy chủ với AWS:
✅ Thu nhập dữ liệu cảm biến qua API Gateway
✅ Xử lý logic bằng Lambda (Node.js)
✅ Lưu trữ trên DynamoDB với partition key 'device_id' và sort key 'timestamp'
✅ Triển khai dashboard React qua Amplify CI/CD
Tập trung giải pháp "Ship It" prototype thay vì kiến trúc phức tạp. Lưu ý cảnh báo bảo mật và hạn chế ScanCommand khi scale.#Serverless #AWS #IoT #DynamoDB #CloudComputing

It's been a while since I posted a new blog post. A few days ago I needed to go off the beaten path while working on one of my Enhance based AWS projects, so I thought I might as well document the ride.

#AWS has released an analysis of the major October outage, highlighting key lessons on:
⇨ cloud redundancy
⇨ multi-region architectures
⇨ considerations for moving workloads out of the public cloudTriggered by a failure in Amazon #DynamoDB, the outage affected a wide range of services in its busiest region, Northern Virginia.
