#ec2 — Public Fediverse posts

Audit EC2 security groups for open inbound rules with AWS CLI. This snippet scans for 0.0.0.0/0 access, prints group, port, protocol, CIDR, and can optionally remove the rule. Works on Ubuntu, Debian, RHEL. #aws #ec2 #security-groups

Ah, another thrilling saga from the "Sane Engineer" 😴, who heroically endures the Herculean task of pitting #PostgreSQL against a whopping 23 #EC2 instances 💪. Spoiler alert: after endless #benchmark babble, it turns out that bigger disks and more CPUs handle data better—who would've guessed? 🙄✨

[Перевод] Как Reddit без потерь перенес петабайтную Kafka с EC2 на Kubernetes

Миграция — риск даже для небольших инфраструктур. А когда у вас больше миллиарда пользователей и петабайт данных, права на ошибку нет вообще. Но выход всё равно один — грамотно спланировать переезд и... взять и сделать. В статье — о том, как Reddit перешёл на Kubernetes: почему они отказались от Amazon EC2, какие ограничения им пришлось учитывать и чем их опыт может быть полезен в других проектах.

I wrote my first article in the #DiaryOfALazyDeveloper series 🚀

I needed to expose a Docker Compose app for a workshop: HTTPS, custom domain, backups, teardown with one command. ECS was overkill, manual setup was fragile.

🔮 Spoiler: one terraform apply does it all 🏗️

In the article I describe every choice and why, driven by experience and the laziness of doing things by hand 😄

System Administration: Week 5: Networking I: IPv6 Basics

In this video, we get familiar with our Big Hero IPv6, looking at the structure of the IPv6 header and IPv6 address representations.

Since we're using AWS #EC2, remember that we have instructions for how to set up a dual-stack VPC and subnet to launch your instances in:

@kabads Interesting, looks like it could work. I feel like "Launch a #Linux instance on #AWS #EC2 and log into it using #SSH" would be a straight-forward, "golden path" workflow...

#AWS has implemented a ~15% price increase for EC2 Capacity Blocks for ML across all regions.

The change impacts organizations reserving dedicated GPU capacity for large-scale #ML workloads, with uniform increases across AWS’s most powerful ML instances.

Реальный кейс настройки Pod Autoscaling в k8s с точки зрения разработчика

На носу 2026 год, а я хочу поделиться своим путешествием по переводу приложения на инфраструктуру Kubernetes. И самая сложная и интересная часть, как раз, настройка автоскейлинга. Не слишком ли заезженная тема? Думаю нет, потому что я буду рассказывать именно с позиции разработчика приложения, а не девопса. Мне повезло, я без понятия как это всё настраивается. Я буду рассказывать как это всё работает. Конфигов кубера будет минимум, рассуждений и погружений в метрики максимум. В конце оставил TL;DR. Поехали?

Tag der Computersicherheit. Für uns ein Reminder: Sicherheit entsteht nicht durch Abwarten. ARA, MQC, EC2 und SCA-QS bringen neue Rechnerlogik, mobile Quantenpower, geschützte Datenverarbeitung und Quantensensorik gegen Angriffe. Zukunftssicherheit passiert nicht von allein – wir treiben sie voran. Wir sind die Pionier für digitale Sicherheit.
