I'm using AWS S3 as my CDN to store files. Often these are directly linked from places all over the world. I'd like to track the file downloads in the S3 bucket using Google Analytics. It appears Google Analytics Measurement Protocol may be able to do this. But since I'm new to both the AWS environment and GAMP, I was hoping I'm not the first to ever do this. Anyone know of a way this can be accomplished?
I doubt this is possible without you doing extra work on top.
You could create a proxy site that, when hit, records an event to Google Analytics and then redirects to the download page/bucket.
You could also maybe have some script/job/etc scrape events from the AWS dashboards and write them to Google Analytics, although this would probably be less than real-time.
You can turn on logging for the buckets you care about, then download the little logfile fragments that Amazon delivers and feed them into an off-the-shelf analytics package such as Webalizer. If you're willing to spend the time and effort to build a pipeline and massage the data so that it fits.
I've written about how to do that here:
https://www.expatsoftware.com/articles/2007/11/roll-your-own-web-stats-for-amazon-s3.html
If you just want the reports today, there are a handful of 3rd party services built around doing this for you, so if you have ~$10/month to spend that's probably the best solution.
S3stat (https://www.s3stat.com/) is my suggestion. But then it should be since it's also my product.
For the last 6 or years, I've been running an online video hosting site.
Back then, hosting your content on services like S3 wasn't the biggie that it is today, so everything is currently stored on our very expensive dedicated servers. The overages on data are much more expensive.
My question is this: What is the process of moving TB's of data on to a service like Amazon Aws where the site is all coded to link to files on our current server.
Editing hundreds-of-thousands of video links to point to the new Amazon AWS locations surely wouldn't be the ideal?
In this situation, is there a more "easy" approach to this dilemma.
All files are in a singular folder structure. IE; example.com/files/video.mp4
Would it possibly be more of a, leave the current files were they are and just have all future videos put on AWS?
I feel like I'm missing a piece of how this works as if for example IMGUR (who has trillions of images) wanted to move from AWS to another similar storage, it would be impossible to re-link trillions of links.
Any help is appreciated.
I'm building an app that will deal with very large files 100mb->1gb both upload and stream around the world.
Obviously streaming/downloading is ok thanks to amazon cloudfront.
But importantly I want users to be able upload as fast as possible... surely it's best if the bucket is in the region?
I've found nothing googling. My bad solution would be a different cloudfront link for each of my regional buckets.
Surely there is a better way...
Thanks in advance!

In my experience the limit to uploading speed is the 'last mile' of the user's connection, not the networks that deliver content to Amazon.
For a recent client we did extensive testing of different S3 zones for uploading large files, and always found our own connections to be the limiting factor.
Choose the zone that is most beneficial to you, whether that be geographically or cost wise.
We have created a product that potentially will generate tons of requests for a data file that resides on our server. Currently we have a shared hosting server that runs a PHP script to query the DB and generate the data file for each user request. This is not efficient and has not been a problem so far but we want to move to a more scalable system so we're looking in to EC2. Our main concerns are being able to handle high amounts of traffic when they occur, and to provide low latency to users downloading the data files.
I'm not 100% sure on how this is all going to work yet but this is the idea:
We use an EC2 instance to host our admin panel and to generate the files that are being served to app users. When any admin makes a change that affects these data files (which are downloaded by users), we make a copy over to S3 using CloudFront. The idea here is to get data cached and waiting on S3 so we can keep our compute times low, and to use CloudFront to get low latency for all users requesting the files.
I am still learning the system and wanted to know if anyone had any feedback on this idea or insight in to how it all might work. I'm also curious about the purpose of projects like Cassandra. My understanding is that simply putting our application on EC2 servers makes it scalable by the nature of the servers. Is Cassandra just about keeping resource usage low, or is there a reason to use a system like this even when on EC2?
CloudFront: http://aws.amazon.com/cloudfront/
EC2: http://aws.amazon.com/cloudfront/
Cassandra: http://cassandra.apache.org/
Cassandra is a non-relational database engine and if this is what you need, you should first evaluate Amazon's SimpleDB : a non-relational database engine built on top of S3.
If the file only needs to be updated based on time (daily, hourly, ...) then this seems like a reasonable solution. But you may consider placing a load balancer in front of 2 EC2 images, each running a copy of your application. This would make it easier to scale later and safer if one instance fails.
Some other services you should read up on:
http://aws.amazon.com/elasticloadbalancing/ -- Amazons load balancer solution.
http://aws.amazon.com/sqs/ -- Used to pass messages between systems, in your DA (distributed architecture). For example if you wanted the systems that create the data file to be different than the ones hosting the site.
http://aws.amazon.com/autoscaling/ -- Allows you to adjust the number of instances online based on traffic
Make sure to have a good backup process with EC2, snapshot your OS drive often and place any volatile data (e.g. a database files) on an EBS block. EC2 doesn't fail often but when it does you don't have access to the hardware, and if you have an up to date snapshot you can just kick a new instance online.
Depending on the datasets, Cassandra can also significantly improve response times for queries.
There is an excellent explanation of the data structure used in NoSQL solutions that may help you see if this is an appropriate solution to help:

So, I have a dedicated server. I host about dozen or so small sites.
Is there a real benefit in using S3(or Mosso) for my image and static file hosting? My server has more than enough disk space, or am I completely missing the point of S3?
I keep reading about how wonderful and cheap it is, and I ask myself "self, why aren't you using this" and the reply is always "why?"
if you're running within the included storage and bandwidth of your server and your needs are being served well, you are already doing the simplest thing that is working for you and that is where you should always start. Off the top of my head I can think of a couple reasons why you may want to move some storage to S3 in the future:
Your storage or bandwidth needs grow beyond what you have and S3 is cheaper than upgrading your current solution
You move to a multiple-dedicated-server solution for failover/performance reasons and want to be able to store your assets in a single shared location
Your bandwidth needs are highly
variable (so you can avoid a monthly
fee when you're not getting traffic) [Thanks Jim, from the comments]
If you run an entire website off of a single machine, and that machine is more than enough to handle your site, then kudos, images are not a bottleneck that needs solving right now. Forget about S3 for now.
However, as your server gets busier, you will want your server to be spending all of its time doing server things. Transferring static content like flat HTML files and images is an easy, dumb job, and wasting precious active connections, bandwidth, and CPU cycles on them is no good. By switching to S3, your server can concentrate on doing what's important, which is whatever your program actually DOES.
S3 also has benefits of being distributed around and attached to what's probably a fatter pipe than your server, which means the images will show up slightly more quickly on your client's machines, so that's an added bonus.
S3 is also backed up, which means that it makes for a pretty nice place to store pretty much any private data under the sun, in addition to stuff that you want to serve to others (although don't confuse the permissions settings between those two things -- in fact, you may want to use separate accounts entirely).
S3 is also nigh-infinite, which means that if you want to let users upload files to your site (profile images, attachments, etc), S3 is a great choice so that you don't have to constantly worry if your server is going to run out of disk space (obligatory $$$ warning here).
But like I said at the top, if you're a one-server setup with a handful of users, none of this really matters. It's a tool like any other, and it may not be something you need yet.
It's simply a matter of doing the numbers: given a certain amount of traffic for a set of files, you can calculate exactly how much hosting those file on S3 would cost you, and you should be able to do the same for your current provider. If the number is lower for S3, there you have your reason.
An added benefit is that S3 scales pretty much linearly with traffic and you pay only for what you actually use, whereas most providers charge you a flat fee no matter how little traffic you actially have, and some will gouge you badly if you ever exceed the maximum traffic included in the flat fee.
Better speed and availability could be an additional benefit.
Basically, if you have a site that could potentially incur wildly disparate traffic, then using S3 for its images and other static files means that if you're hit by the Slashdot effect, the site has a much better chance of staying reachable, and you have a much better chance of avoiding nasty surprises concerning excess traffic fees.
The advantages of Amazon S3 are reliability, scalability, speed and cost. Here is some info on each.
Reliability: Amazon stores your data in multiple data centers. If there was a disaster and one data center was destroyed your content would continue to be served from the second data center. It’s very unlikely that data you upload to Amazon would ever be lost.
Scalability: If one of your web sites becomes popular and millions of people visit the site, your web server will not be able to handle the load. In comparison when you upload your files to Amazon they are stored in multiple locations. If the load on your content grows your files are automatically replicated to more servers so your files will always be available.
Speed: Amazon has a service called CloudFront that works in conjunction with Amazon S3. When you activate CloudFront on your S3 content your content is moved to edge locations. These are servers that make your content available for high speed transfer.
Cost: With Amazon S3 you only pay for what you use. If you have a few files that get little traffic you will only pay a few cents a month.
SprightlySoft has a blog post which gives even more reasons why Amazon S3 is great. Read it at http://sprightlysoft.com/blog/?p=8
If you're hosting a high-traffic site, the bandwidth cost (and latency issues) of hosting images yourself makes S3 and other services like Akami attractive. For a low-traffic site, it probably isn't an issue.
I'd say that there's no reason if your base hosting plan provides enough space/bandwidth. Where I think it's useful is when your file transfers become enough that you have to look at buying an add-on of storage/bandwidth from the provider -- in that case, S3 may be a viable alternative. But if I'm paying $X/month and not using all of the storage, there's no upside to it.
On the other hand, if your capacity planning calls for you to someday exceed the provider's limits, S3 may be a good solution from the start so you don't have files being served from multiple places.
I would second the mention of "redundancy" -- you can count on any content that's in S3 to be distributed to multiple data centers, and effectively been very much always accessible for anyone with functioning network connection.
Cost may be another factor: data transfer rates for S3 are quite competitive.
And speed is the last one: you can access data VERY fast from S3. But that's more of an issue for data other than browser-viewable images.
For small sites, S3 or Mosso may not be that reasonable for image hosting, but if you have any video files (.wmv, .flv, etc...) or large downloads (app distributions, etc..), I'd still put them on S3 or Mosso to save potential bandwidth spikes if for some odd reason, your content becomes wildly popular.
You write:
My server has more than enough disk space, or am I completely missing the point of S3?
You are not missing the point if what you have on you server is write-once read-less-than-once stuff, such as disaster-recovery backups (which you hope will be read-never), because transfer times will not matter. The point of S3 is delivery speed.
First, S3 distributes your content geographically. End users benefit from shorter paths.
Second, S3 can act as a BitTorrent seed, which not only conserves your bandwidth, it means your most popular content will be distributed faster because it can take advantage of the ad-hoc swarm. There are reports on the AWS Discussion Forums that S3 support of the BitTorrent protocol is "very, very spotty." I have not tested it myself.
Many of you won't have this problem, but if you (and your web server) are located in Australia (read: the 3rd world of the Internet), you run into the issue that S3 does not have geographically close locations, which means there will be a higher latency on your images and other static content. Scalable: yes. Fast: no.
From what I hear, besides low cost, the main advantage is the ease of backup from an EC2 setup.

Speed might be the only benefit. If your dedicated server is simply networked through your ISP (which may well throttle upstream speeds even if downstream speeds are high) then you might find that your sites are often slow to load. If so, then S3 or another dedicated server provider can help. Other than that, I can think of absolutely no reason why Amazon's service would be more appropriate for you - especially with simple, static sites.
It's not really directly related to your actual hosting of web sites, but it's certainly an important part of it, especially if the sites don't belong to you alone -- S3 is a great backup solution. There are tools such as duplicity that can automatically and efficiently back things up onto S3 for you, and it's extremely cheap for this purpose. I back up a fairly large amount of data for less than $1/month.
Besides the Fat Pipe and Local Delivery arguments for S3 there is also the manner of a single server does not function optimally when its functioning both as a db server and as a file server. If your running any sort of db I would suggest offloading all your static files to s3. The cost is trivial and you will see pretty big performance gains on page load.
