​​Self-Host Your Static Assets

This, at first glance, a counter-intuitive proposition has a strong argumentation and affects a large number of aspects from the basic problems of the security component and the downtime of 3'rd parties (for example, the recent drop of 15% of the Internet) to fine-tuning optimization, which is often neglected even by good engineers.

At the same time, process optimization is the basic requirement of any business, and for the business that wants to grow in the modern world, the speed of its Internet services is one of the key metrics that directly affects the number of different benefits that business can give you. And if you are interested in this topic as me - I recommend to visit @notieinIT, where the clipper CTO talks about various technical and cultural aspects of optimization, explains in simple terms unexplained and reminisce things forgotten long time ago.

Визуальная IDE для Kubernetes k8s Studio вышла в бете

В треде на Реддит ссылка, чтобы попроситься в бету и ссылка на Слак разработчиков.

Проект не open source, что там по ценам - не ясно.

Если никогда не слышали об этой поделке, можно глянуть информацию на из сайте

How Google got rid of VPN and other old(?) security methods

They called it BeyondCorp and it main goal sound as:
Every Google employee work successfully from untrusted networks without the use of a VPN. It needed for improving productivity and keep company secure.

Implementation started in 2011 and successfully ended in 2014, proccess was described in this article. Now Google starts sharing the lessons that they have learned over the 5 years of exploitation.

P.S. On Google SSO page you can find random pictures (: desktop version required)

​​ec2-metadatafs: 'cat' your AWS EC2 metadata

This tool exposes AWS EC2 metadata as a filesystem for easy ls, cat, and grep'ing.

Advantages over curl http://169.254.169.254:
- Support for tags
- Use filesystem permissions to control access
- Use traditional unix tools to walk and interrogate the tree
- Tab completion of paths
- No need to remember the special IP address of the service

Advantages over the ec2-metadata tool:
- Support for tags
- No need to cut the output of commands to get just the field
- Can use filesystem permissions to control access
- Access to all metadata fields, not just the limited subset the tool returns

Well and browsing the metadata endpoint as a filesystem from an EC2 instance is really cool idea.

​​Пока уважаемые люди до сих пор спорят в Интернете, существуют "DevOps инженеры" или нет, моя принципиальная позиция в том, что DevOps инженер - это инженер, которому мало одного профессионального праздника в году.

С днём сисадмина! Так сказать, первым профессиональным праздником в этом году.
Что-то давненько про Kubernetes не было.

- Описание деплойментов от Jérôme Petazzoni - одного из бывших разработчиков Docker
