Thanks for putting this up. I'd be very intrested to know if anyone has ever done a similar test with Azure?

chookrl• 13 years ago

We haven't tested Azure Cloud Storage. However, we did test other cloud computing hosts such as GoGrid and Rackspace. Their upload speeds were almost the same and sometimes even better than EC2 when uploading to AWS S3. Perhaps we will test Azure in a follow-up post.

Interesting!! We've tried conducting similar tests where I work a few months ago. We had to deploy a few servers and tried to figure out the optimal spread.

For anyone interested in optimizing S3 performance, I recommend Jim Sorenson's "Building Scalable Applications on Amazon S3" from re:Invent.

His comments on hashing for S3 buckets were pretty interesting.

Here's a very informative blog post by Doug Grismore that talks more about this if you are interested: http://aws.typepad.com/aws/2012/03/amazon-s3-performance-tip...

Interesting. It might also be useful to see latencies between regions (or even availability zones).

Any idea why the results are not symmetrical? Upload from Virginia to California is twice as fast as from California to Viriginia (and it's even worse with US <-> Japan).

Are there strategical interests to not have a symmetric link?

Xylakant• 13 years ago

Maybe the link is symmetric, but the traffic flow is not - so in one direction the intertubes are more clogged.

Actually, the results are reverse from what you said (y-axis is the origin). It likely has to do with traffic congestion coming out of each datacenter. Virginia has by far the heaviest use out of all the datacenters.

Australia is has low bandwidth to the rest of the world largely due its geography and capacity/path of the undersea cables connecting the country.

Geographically its relatively close to Singapore (compared to other data centers anyway), all of the cables from the eastern side of the country either go up to Japan via Guam or go to the US via Hawaii. Its not uncommon to see a route from Sydney to Singapore go through the US, and/or Japan before reaching Singapore.

You know, I know it's 2013 and all, and things like this shouldn't amaze me, but the fact that you can get data from Australia to Brazil in _minutes_ is still kind of astounding to me.

Keep in mind that the S3 Virgnia location (known as US Standard Regionin AWS terms) includes endpoints in Virginia and in the Pacific Northwest. Hence that may be why the Virginia to Virginia numbers were high compared to the other regions.

"The US Standard Region automatically routes requests to facilities in Northern Virginia or the Pacific Northwest using network maps." http://aws.amazon.com/s3/

If that's the cause of slowness then their network maps are broken.

donavanm• 13 years ago

The us-east and SEA end points for US Standard buckets are directly addressable as well. Consistency will be tighter if you PUT and GET to the same endpoint.

Edit: that's be s3-external-1.amazonaws.com for us-east and s3-external-2.amazonaws.com for the PNW. See https://forums.aws.amazon.com/message.jspa?messageID=185820
