Hacker News Daily 上看到這則，分享了 AWS (他的前東家，超過八年) 的使用經驗：
This is how I use the good parts of @awscloud, while filtering out all the distracting hype.

除了可以在 Twitter 上看以外，也可以用 Thread reader 直接讀整條 thread，應該也還算清楚：「This is how I use the good parts of @awscloud, while filtering out all the distracting hype.」。
這邊的經驗談主要是在 web 與 app 相關的服務這塊：
My experience is in web- sites/apps/services. From tiny personal projects to commercial apps running on 8,000 servers. If what you do is AI, ML, ETL, HPC, DBs, blockchain, or anything significantly different from web apps, what I’m writing here might not be relevant.

有講到 AWS 的業務其實圍繞在 scalability 上發展，但這對 startup 可能反而是扣分，因為暴力法解反而可以大幅簡化架構換得 agile (而讓 startup 存活下來)。
另外從團隊的開發成本來看，這些 scale 的技術增加了開發成本，產生了很多開發上的限制，這些觀點也有點帶到「Premature optimization is the root of all evil」在講的事情：
Step 1: Forget that all these things exist: Microservices, Lambda, API Gateway, Containers, Kubernetes, Docker.
Anything whose main value proposition is about “ability to scale” will likely trade off your “ability to be agile & survive”. That’s rarely a good trade off.

最後的結論可以看到一些列表：
Conclusion: I like to seperate interesting new tech from tech that has survived the test of time. EC2, S3, RDS, DDB, ELB, EBS, SQS definitely have. If you’re considering alternatives, there should be a strong compelling reason for losing all the benefits accrued over time.

除了 DynamoDB 的意見不同外 (這邊提到的 DDB)，其他的我都可以接受...
