An article on why on site coding assessment doesn't fit for hiring senior engineers
I personally tend to agree that live coding sessions are not good. If you want to check their coding skills, give them a home assignment or ask for a public example if they have one.

~8yrs ago (Dec’12) I got a job @Google. Those were still early days of cloud. I joined GCP @<150M ARR & left @~4B (excld GSuite). Learned from some of the smartest ppl in tech. But we also got a LOT wrong that took yrs to fix. Much of it now public, but here’s…
Yet another DevOps roadmap.
Might be interesting for those who just want to start their career path in this field.
However, I have a strong opinion that the only sane way to excel in a "hybrid specialization" is to get into one of "pure specializations" first. I.e. if you want to become SRE, start with operations, get familiar with it and then learn the Dev part. Alternatively, as a developer start to interest yourself in operations.
Your career is a marathon, not a sprint.

A Medium post with some benchmarks of gp2 vs gp3 AWS volumes
Putting it into the author's words: "There is no such thing as free lunch". You have cosider tradeoffs. When you're getting cheaper disks, you may see lower performance. This is not a critical issue, this is something you have to always keep in mind.

How GitOps Improves the Security of Your Development Pipelines
Наткнулся на свежую статью, приводящую примеры того, как методология GitOps может улучшить безопасность вашей среды. К основным примерам относятся аудит и ограничение доступа CI/CD системы. Про проблемы классического подхода DevOps и решения GitOps также можно прочитать в статьях:
- How secure is your CICD pipeline?
- How GitOps Raises the Stakes for Application Security
Однако, как и везде, есть подводные камни. Хорошая статья на тему рисков, связанных с GitOps:
- Securing GitOps Pipeline
В основном здесь все сводится к угрозам системы контроля версий, но не стоит также забывать про RBAC. Ведь, несмотря на широкое ограничение доступа согласно методологии, оператор GitOps все еще может стать отправной точкой для злоумышленника. Еще одна проблема - сильная зависимость от кода и уход от подходов, связанных с контролем Run-time через тот же OPA. Как показывает практика, статические анализаторы далеко не всегда хороши в определении полной картины проблем, связанных с ИБ.
Пока комьюнити ищет золотую середину в подходах, предлагаю вам также прочитать следующий материал:
- GitOps Security with k8s-security-configwatch by Sysdig
- Access Control & Security (GitOps and Kubernetes Book) (у кого есть полная версия книги, буду рад почитать)
Кстати, если вы не знакомы с методологией, то мне нравится перевод от Flant.
