This sort of thing drives me nuts in interviews, when people are like, are you familiar with such-and-such technology? Yeah, what month?

If you're aware of changes, then explain that there were changes over time, that's it

You say this, someone challenges you, now you're on the defensive during an interview and everyone has a bad taste in their mouth. Yeah, that's how it goes.

I think there is more of us who kind of degenerated from doing it the AWS way - API Gateway, serverless lambdas mess around with IAM roles until it works, ... - to - Give me EC2 / LightSail VPS instance maybe an S3 bucket let's set domain through Route53 and go away with the rest of your orchestrion AWS.

At what point is AWS worth using over other compute competitors when you’re using them as a storage bucket + VPS. They’re wholly more expensive at that point. Why not go with a more traditional but rock solid VPS provider? I have the opposite philosophy for what it’s worth: if we are going to pay for AWS I want to use it correctly, but maximally. So for instance if I can offload N thing to Amazon and it’s appropriate…

Most work isn’t greenfield.

AWS can be used in a different, cost effective, way.

It can be used as a middle-ground capable of serving the existing business, while building towards a cloud agnostic future.

The good AWS services (s3, ec2, acm, ssm, r53, RDS, metadata, IAM, and E/A/NLBs) are actually good, even if they are a concern in terms of tracking their billing changes.

If you architect with these primitives, you are not beholden to any cloud provider, and can cut over traffic to a non AWS provider as soon as you’re done with your work.

..oh. That's clever. Thanks for posting this.

I am also assuming that Amazon intends for the Deep Archive tier to be a profitable offering. At $0.00099/gb-month, I don't see how it could be anything other than tape.

http://www.patentbuddy.com/Patent/20140047261 Is tape even cost competitive anymore? The market would be tiny.

One way to know is to see if new tape products exist, indicating ongoing development. As of May, 2025, LTO-10 is available, offering 30TB/75TB (raw/compressed) storage per cartridge. Street price is a bit under $300 each. Two manufacturers are extant: Fujifilm and IBM.

VPC sharing is the sleeper here. You can do cross account networking all in the same VPC and skip all the expensive stuff.

as long as your VPCs aren't too big, yea.

If you are exhausting an entire VPC I’d be pretty impressed!

S3: "Block Public Access is now enabled by default on new buckets." On the one hand, this is obviously the right decision. The number of giant data breeches caused by incorrectly configured S3 buckets is enormous. But... every year or so I find myself wanting to create an S3 bucket with public read access to I can serve files out of it. And every time I need to do that I find something has changed and my old recipe d…

I’m getting deja vu, didn’t they already do this like 10 years ago because people kept leaving their buckets wide open?

It feels odd that this is some sort of secret. Why can't you talk about it?

I signed NDAs. I wish Glacier was more open about their history, because it's honestly interesting, and they have a number of notable innovations in how they approach things.
