Is there enough supply of treasury bonds and other low risk debt to do this?

SQLite has a write ahead log (journal) mode. If you write that log to some store that is already replicated (S3, CloudFlare Durable Objects, Kafka?) then the concept of a 'master' is less important.

Since it's a relational DB, and supports transactions, you can have a journal table right? I know of a very important system at AWS that did this with MySQL :D

I've never seen (healthy) fleets with average CPU utilization above 70-80%. That includes several-thousand machine fleets when I worked at Amazon. Most things I've seen in my career have 10-20% utilization at best. The Lambda &q

Where are the borrowers investing the tokens to generate profit to pay interest to the lenders? Like, are they investing in real estate that pays rent? Companies that pay dividends?

Do you have any examples of non-crypto companies trying to spin a $100MM fine as "pioneering efforts in securing regulatory clarity"? I know companies spin, but this is next level.

Do you get a sign on bonus thats like 50% of TC for the first two years at other companies? Because thats what amazon does.

Is it really a common problem? I've had a Rav4 for 3 years. I use the adaptive cruise control a lot on highway/freeway and I have never, ever had it exhibit phantom braking. It will sometimes brake a little longer than you expect

I just want to applaud the author for being direct, and not couching their opinions in a bunch of caveats^1. Sometimes a little bit of directness (in good spirits) helps move discussions, and people's understanding forward. ^1: Except

Hehe true! But it's real hard to "move fast and not break things" when you're talking about millions of servers, exabytes of data, and tens of thousands of engineers.

Yes, but many services, including S3, SQS, and DynamoDB did not run on the EC2 network for most of their existence.

It's 2006, you work for an 'online book store' that's experimenting with this cloud thing. Are you going to build a whole new network involving multi-million dollar networking appliances?

Yeah, teams go to a lot of effort to have zonal environments/fleets/deployments... but there are still many, many regional failure modes. For example, even in a foundational service like EC2 most of their APIs touch regional datab

I saw pleeeeeenty of untested code at Amazon/AWS. Looking back it was almost like the most important services/code had the least amount of testing. While internal boondoggle projects (I worked on a couple) had complicated test pla

Take DynamoDB as an example. The AWS managed service takes care of replicating everything to multiple AZs for you, that's great! You're very unlikely to lose your data. But, the DynamoDB team is running a mostly-regional service.

by discodave 5y ago
Your application can call DynamoDB via the public endpoint (dynamodb.us-east-1.amazonaws.com). But if you're in a VPC (i.e. practically all AWS workloads in 2021), you have to route to the internet (you need public subnet(s) I think) t

You're overthinking it, and Code Pipeline is just one example. As I'm writing this they have close to 300 services!!! Many of them, maybe hundreds of them just straight up lose money. The Corey Quinn number I keep quoting is that

An underestimated chunk of AWSs costs is people. They employ >50k people, and likely have a salary bill of several billion dollars, a significant portion of revenue. 50,000 x 250k = 12.5B Also, they do cross-subsidize, because many AWS s

This is actually a great way to think about it for a number of reasons. 1. Look up what James Hamilton (AWS Distinguished Engineer) has been saying for years about commodity economics disrupting things. It's about the money, stupid

Yes. Amazon offer generally gives you roughly the same "total compensation" for the first 4 years, assuming that the stock price doesn't change much. So if they're trying to pay you 300k per year, then you get 160k salar
