Ephemeral Environments: Automating QA for Reliable Cloud-Native Systems Ephemeral environments are short-lived, isolated, fully provisioned, on-demand test environments created automatically from a pull request and destroyed the moment their job is done. This guide walks through why traditional environments fail, what ephemeral environments actually are, the modern stack that powers them, and a concrete, code-level blueprint for building your first ephemeral testing pipeline.

An 8-minute outage from a dead NLB and a JVM that cached DNS forever We drained a Network Load Balancer during a planned migration, and one internal service kept hammering the dead IPs for 8 minutes. The cause wasn't the failover. It was a JVM caching the DNS record forever. The fix was a 30-second TTL and a health-check tweak, not a smarter system. Ссылка скрыта

Dagster on Kubernetes: When More Nodes Won't Save You You've scaled up your Kubernetes cluster. EC2 instances are running. CPU and memory metrics look reasonable. And yet — the number of completed Dagster runs stubbornly refuses to climb. This article walks through the full diagnostic journey — from the obvious knobs to the hidden PostgreSQL bottleneck that probably nobody warns you about. Ссылка скрыта

OpenViking OpenViking is an open-source context database for AI agents. It stores memories, resources, and skills as one virtual filesystem under the viking:// protocol, so an agent browses its own context with ls, tree, and find instead of querying a black-box vector store. Content is processed into three tiers — L0 abstract, L1 overview, L2 details — and loaded on demand. Every retrieval leaves a trajectory you can watch and debug. Ссылка скрыта

⚡️⚡️Инциденты, метрики и спасенный прод на DevOops 2026 Даже самая отказоустойчивая инфраструктура иногда преподносит сюрпризы, а один неудачный коммит может устроить всей команде долгий вечер. На DevOops 2026 будут разбирать, что делать с такими ситуациями в реальной инфраструктуре: от проблем с Kubernetes и GitOps до инцидентов, метрик и observability. Программный комитет выбрал восемь докладов, которые рекомендует посмотреть в первую очередь. Здесь — Kafka в Kubernetes, архитектура корпоративного GPT, GitOps без лишнего blast radius, security-политики, надежность, DORA и observability. Все подробности — в карточках и на сайте. 🔥С промокодом devopslibrary персональные билеты дешевле Купить билет
