Amazon S3 Design Principles

The following principles of distributed system design were used to meet Amazon S3 requirements:

Decentralization: Use fully decentralized techniques to remove scaling bottlenecks and single points of failure.

Asynchrony: The system makes progress under all circumstances.

Autonomy: The system is designed such that individual components can make decisions based on local information.

Trigger warning: mention of suicidal ideation

tl;dr: I burned out as a developer at Amazon at the end of my second year. I’ve since found a healthy and sustainable work-life balance and enjoy work again. I write this to A) raise awareness, especially for new-hires and their families, and B) help give hope and advice to people going through the same at Amazon or other companies.

Hello, world

There’s been no shortage of anecdotes, opinions, and rebuttals regarding Amazon’s corporate culture as of late. I write this not to capitalize on the latest news-feed fad, but to share what I had already written and promptly deleted. I didn’t think anyone would want to hear my story, but it’s apparent people are going through a similar experience and don’t have a voice.

I’m a Software Development Engineer II at Amazon; SDE II basically means a software developer with at least 2–3 years of industry experience. I started at Amazon as an SDE I.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
