For two decades, S3 has been an object store, but today it's something broader. S3 Files lets you mount any bucket as a filesystem—no copies, no sync scripts, no choosing between file and object. @andywarfield tells the full story, including the "filerectories" that almost made the cut. allthingsdistributed.com/2026/04/s3-fil…

I wrote an article for All Things Distributed about today's S3 Files launch, and some of the engineering story behind it. allthingsdistributed.com/2026/04/s3-fil…

Some thoughts on the S3 Vectors preview launch this week. This one has been really fun to build, and it's exciting to be able to finally share it! linkedin.com/feed/update/ur…

Today is #PiDay. I wrote an article for @Werner's blog about how important the idea of simplicity is in S3 and reflect on some examples of how simplicity has influenced S3's design over almost two decades. allthingsdistributed.com/2025/03/in-s3-…

Wish we'd thought of positioning it this way...

Really fun post from Werner and team about building with rust, media summarization, and the importance (and enjoyment!) of tinkering in systems. Great read. allthingsdistributed.com/2024/06/introd…

Hey @lookbindings, I absolutely loved my pivot 360s. Right until the metal snapped and turned them into a sharp edge attached to my ski as I fell down the run.

@QuinnyPig @CTOAdvisor That’s pretty awesome. But just so I’m clear: you are saying that route 53 is definitely not a database, right?

@andywarfield Fun story as per your conversation with @CTOAdvisor: the “Route 53 is a DB” gag was originally going to be about S3. I changed it at the last minute because using S3 that way wasn’t actually ridiculous.

I will say that I find the giant picture of me to be a little unnerving, but the article itself is great.

Customers are very vocally asking us to bring S3 closer to their applications and to developer interactions with their data. Tim's article does a great job of talking about where the team is heading.

I loved talking to Tim Anderson from the Register at re:Invent this year. It was a really fun conversation about a bunch of the S3 announcements. theregister.com/2023/12/12/the…

Last week was re:Invent, this week I'm helping my dad build barn doors. #storage #builders

Deets on the latest S3news for 10x latency reduction ⚡#reInvent recaps. Andy Warfield discusses S3 Express One Zone, @amazon’s solution for more responsive data interactions. 📰 More: siliconangle.com/2023/11/30/ama… @andywarfield @Furrier #theCUBE #Supercloud5

@0xdabbad00 Mai-Lan did a section in Werner's keynote at re:Invent at 2018. If you look in here at around 5:50, there's a good characterization of how S3 thinks about this stuff. youtube.com/watch?v=nLyppi…

@0xdabbad00 Scott, this is a good call out. 11 9s is a number that we design for internally in engineering against component failures like drives and servers. We use it to choose redundancy schemes and size repair fleets. AZ failures are treated separately here: docs.aws.amazon.com/AmazonS3/lates…

I am uncomfortable with how S3 Express One Zone is discussed as still having 11 9's of durability, like normal S3. Data is spread across multi hard-drives still, but all within one zone. youtube.com/watch?v=sYDJYq…

Almost time to talk about storage!

I am so excited at our launch of S3 Express One Zone. This product has been an incredible amount of really innovative work from an incredible team and it's wonderful to finally be able to share it with customers! aws.amazon.com/blogs/aws/new-…

@neugebar Pretty sure my grey hair started with that paper!

This morning I'm coming to terms that it's been 20 years since we wrote the Xen paper. That sure went by fast!
