First month data using S3 offloading for WPMU

April was our first month of using the themes-s3 plugin for offloading WordPress-Mu theme files to Amazon-S3. I have received the monthly bill from Amazon just a few days ago and thought I would share the numbers. So here you go ( the numbers in bold are the real costs):

$0.15 per GB-Month of storage used 0.006 GB-Mo $0.01
$0.10 per GB – all data transfer in 0.011 GB $0.01
$0.18 per GB – first 10 TB / month data transfer out 2.784 GB $0.50
$0.01 per 1,000 PUT or LIST requests 3810 Requests $0.04
$0.01 per 10,000 GET and all other requests 2394466 Requests $2.39

The total monthly cost is $2.95 and most of the charge is for GET requests – 2,394,466 of them. As you can se, storage and data are very cheap and according to Amazon’s announcement, this month they will be even cheaper.

Overall performance has improved but offloading is not the only reason. We did a few more thing with our system but “saving” 2,394,466 requests and file servings must have helped.

    Thanks for the numbers. I’m actually surprised that they don’t round up.

    Have you done any work on the idea of moving user files to s3 that you mentioned previously? I have to admit that at the prices listed and if one was to run adverts in some way or ask for donations, you could easily offer all clients a gig or two for their uploaded files. Granted not all of them are going to use that much space but it is something to consider.

    Did you notice any downtime upon s3’s part? (We’ve been having a discussion elsewhere about relying on third party sources for one’s data and if it’s worth the risk of them being down while your own site is still up.)

    It’s not actually gong to get much cheaper. The only difference I see right off is with the data transfer for you. Would have been 17 cents compared to 18 cents.

    Thanks again,

    Mike,

    We do run adverts on our system in a very similar way they are shown at wp.com but at this time there is no demand for more upload space. We allow 50MB (not 51 like you did) and never had a request for more.

    We have not noticed any issues with Amazon’s service but we could remove the plugin at any moment and return to serve the files from our server.

    Regarding the option of serving users files form S3 I have not done any coding but I do think I have a strategy worked out.

    Interesting numbers. Thanks for posting them.
    I’m looking to move a large amount of images to S3 as a sort of reverse backup (will be serving from S3 but keeping copies on my server as well initially) but was worried about huge costs – you have reassured me somewhat.

    Barry,
    Keep in mind that if you are not planning to update each file when it is uploaded or deleted, you will have to sync S3 from your server. These sync operations may be more expensive since they use many GET requests.

    Glad to find your post. I am starting a WPMU + buddypress project for local community, and looking for some personal experience notes.

    Was that data usage is from a WPMU installation serving a few thousand of blogs as you said in http://www.ringofblogs.com/2008/04/12/off-loading-wpmu-theme-files-to-amazon-s3/?

    What about your primary server? Do you use dedicated server?

    huda,
    Yes, the same installation. At that time we didn’t have a dedicated server. Now we do and we don’t offload things.

    Thank you for your answer.
    Do you have any experience how far a shared hosting can hold WPMU installation? (users, database size, traffic, etc.)

    I’m currently using hostgator. Just starting, developing and testing it with a small community, so I think there’s no point switching even to a VPS at this time.

    Thank you in advance, Elad.

    […] my previous post about the first month data of using Amazon’s S3 I had a comment asking about any down time in the service. Well, I have not noticed any down time […]
