What was announced?

According to AWS What's New, the Amazon S3 Express One Zone storage class is now available in 7 additional AWS Regions. Here's the list of newly added regions:

• Asia Pacific (Singapore)
• South America (Sao Paulo)
• US West (N. California)
• Canada (Central)
• Europe (Paris)
• Asia Pacific (Sydney)
• Asia Pacific (Seoul)

With this expansion, S3 Express One Zone is now available in a total of 15 AWS Regions.

The story so far

S3 Express One Zone is a high-performance storage class built around a single Availability Zone (AZ), but until now it was only available in a limited set of regions. If your workloads ran in a region it hadn't reached yet, you simply couldn't use it. This 7-region expansion significantly widens its reach.

What changes

If you're running systems in any of the 7 newly supported regions (Singapore, Sao Paulo, N. California, Canada Central, Paris, Sydney, or Seoul), you can now use S3 Express One Zone's low-latency storage locally, without routing through a different region. That means you get to take advantage of its fast access without worrying about cross-region latency or data transfer.

Dive Deep

S3 Express One Zone concentrates storage in a single AZ to deliver consistent single-digit millisecond data access. Here's what the announcement highlights:

• Data access speed: up to 10x faster than S3 Standard
• Request costs: up to 80% lower than S3 Standard
• Latency: consistent single-digit millisecond data access

The key use cases called out are:

• Machine learning training
• Interactive analytics
• Key-value caching in AI search engines

For pricing details, the announcement points to the S3 pricing page, and for more on the storage class, the product page and documentation.

Wrap-up

• S3 Express One Zone is now available in 7 new regions (Singapore, Sao Paulo, N. California, Canada Central, Paris, Sydney, Seoul)
• Total availability now stands at 15 AWS Regions
• Up to 10x faster data access and up to 80% lower request costs than S3 Standard
• Great fit for ML training, interactive analytics, and AI search caching workloads

If you're looking for low-latency storage in one of these regions, this is well worth checking out!
