HN has a lot of professionals. They can't run a business on a refurbished server without ECC and without RAID and without dual power supplies.

Saying that they should run on kumsufi is like explaining to a wholesale company that they should use motorbikes instead of trucks, because motorbikes are cheaper.

Of course. I'm not telling anybody to run on kimsufi, like I'm not running kimsufi myself, but on brand-new Supermicro machines that check all your boxes.

Kimsufi is still dedicated hardware (however low-end) that costs 1 figure instead of 5/6. For normal server-grade hardware it's just 5x cheaper than AWS, not 20x.

Kimsufi and soyoustart are brands of OVH. You don't need to explain again and again that they sell cheaper servers than AWS. Same for super micro. The HN audience know the common suppliers.

Again, you're arguing for motorbikes instead of trucks because they are cheaper. Noone care about that, trucks were not selected based on costs in the first place.

AWS Advocates Eventual Consistency, and I believe offers less than 3 nines guaranteed uptime on many products.

We've been taught to build distributed system with unreliable componens and temporaral JIT eventual consistency.

Of course we can run production cloud-scale operations on unreliable systems. And single power supplies without ECC or RAID is pretty low on my list of things that cause outages. Most big hadoop/cassandra shops are running without raid and without redundant power.

[user5994461]

hadoop/cassandra are replicated to multiple nodes by the software. That's a terrible argument for not using any raid in regular setups.

I suspect your and my definition of regular setups is different. My regular setups are stateless and automatically installed and configured.

Lucky you, never having to deal with any database or storage.
