I'm using the Engine Yard AppCloud service.
If I want my instances to share storage (e.g. for file uploads/downloads), is my only real option to build S3 integration into my application? At the moment the app expects to use the filsystem but it doesn't look like multiple instances can mount the same EBS volume.
Thanks!
Probably, the simple option is to have an NFS server, have the EBS mounted on it and share that to the instances.
But there are other distributed filesystem that you can use also like glusterfs,moosefs and the like.
There are some shared filesystems that may work on EC2 or AppCloud without a problem however the support of them likely would be 0.
Otherwise I would suggest to look into using s3fs
MogileFS
GlusterFS

Let's say there is a file in this link example.com/file.bin and I want to transfer it to a cloud storage (Mega or Google Drive for example), or I have a download/upload host and want to transfer files from a cloud storage to that host. how can I do that? (Besides the good old downloading-and-reuploading way and transfer sites like Multcloud)
At first I thought I can use python + selenium framework to handle the cloud storage side, but that works only if I have the file on my own system. Can I use a host to deploy the code on it, and then use it to transfer the files? (Some of cloud storages don't have API to use them for downloading, So I think it's necessary to use Selenium)
i just ask for opportunities to mount a shared storage in Windows Server 2016 or higher.
So i found a lot of on AWS EFS, EBS, S3
My problem is to install data of a Software in a shared volume.
EBS is just for local mounting, can i map it on other servers?
EFS ist not for Windows but my favourite choice, are the solutions to mount it as volume in Windows or i should mount it on Linux first?
Is S3 mountable to use it like a file system?
What can i use or what is the best solution für shared storing data using cloud technologies
EBS is just for local mounting, can i map it on other servers?
Indeed, you can mount EBS only to a single EC2 instance. However - you can expose the mounted EBS as NFS on the instance
EFS ist not for Windows but my favourite choice, are the solutions to mount it as volume in Windows or i should mount it on Linux first?
I don't think that matters.. (if I'm mistaken, please correct me)
Edit: I stay corrected, AWS EFS from Windows Server 2012 seem you mouting EFS on Windows doesn't work properly. You could mount the EFS on a linux server and expose it as NFS.
Is S3 mountable to use it like a file system?
S3 is not indeded to be mounted as a filesystem and it's not montable by default. If needed, there are 3rd party tools to do that (e.g. fuse-s3fs on linux), but IMHO it's not the most efficient way.
As well there are solutions from AWS (aws storage gateway) to migrate on-premise content to S3 and back.
Mounting S3 as FS I'd consider mounting S3 only when
the files are created or read, not updated (S3 doesn't support updating part of an object)
the objects (files) are to be shared by other services or through internet
I would like to access my Amazon S3 buckets without third-party software, but simply through the WebDAV functionality available in most operating systems. Is there a way to do that ? It is important to me that no third-party software is required.
There's a number of ways to do this. I'm not sure about your situation, so here they are:
Option 1: Easiest: You can use a 3rd party "cloud gateway" provider, like http://storagemadeeasy.com/CloudDav/
Option 2: Set up your own "cloud gateway" server
Set up a dedicated server or virtual server to act as a gateway. Using Amazon's own EC2 would be a good choice.
Set up software that mounts S3 as a drive. Two I know of on Windows: (1) CloudBerry Drive http://www.cloudberrylab.com/ and (2) WebDrive (http://webdrive.com). For Linux, I have never done it, but you can try: https://github.com/s3fs-fuse/s3fs-fuse
Set up a webdav server like CrushFTP. (It comes to mind because it's stable and cheap and works on any OS.) Another option is IIS but I personally find it's harder to set up securely for webdav.
Set up a user in your WebDav server (ie CrushFTP or IIS) with access to the mapped S3 drive.
Possible snag: Assuming you're using Windows, to start your services automatically and have this work, you may need to set up both services to use the same Windows user account (Services->(Your Service)->[right-click]Properties->Log On tab). This is because the S3 mapping software might not map the S3 drive for all Windows users. Alternatively, you can use FireDaemon if you get stuck on this step to start the programs as a service all under the same username.
Other notes: I have experience using WebDrive under pretty heavy loads, and it seems to work well. Under tons of pounding (I'm talking thousands of files per hour being added to a 5 TB WebDrive) it started to crash Windows. But I'm not sure if you are going that far with it. Also, if you're using EC2, you may not have that issue since it was likely caused by a huge transfer queue in memory and EC2 will have faster transit to S3 and keep the queue smaller.
I finally gave up on this idea and today I use Rclone (https://rclone.org) to synchronize my files between AWS S3 and different computers. Rclone has the ability to mount remote storage on a local computer, but I don't use this feature. I simply use the copy and sync commands.
S3 does not support webdav, so you're out of luck!
Also, S3 does not support hierarchial name spaces, so you cant directly map a filesystem onto it
There is an example java project here for putting a webdav server over Amazon S3 - https://github.com/miltonio/milton-aws
What exactly the SDK can be used for ? Only for storage like it's done on google drive, box or dropbox etc ? Or can i use the stored scripts to run a complete website ?
What exactly the SDK can be used for?
The Software Development Kit (SDK) can be used to programmatically control nearly every single aspect across all 40± AWS services.
Only for storage like it's done on google drive, box or dropbox etc?
Amazon S3 is a storage-only service. It complements the plethora of other AWS services.
Or can i use the stored scripts to run a complete website?
For that, you'd need something with a server. I recommend taking a look at AWS Elastic Beanstalk first because that's arguably the quickest way to get something running. If you're looking for something with more control, you can check out AWS OpsWorks.
If you want a raw virtual server, take a look at Amazon EC2. If you want to build a template that can automate and configure nearly your entire cloud infrastructure (storage, compute, databases, etc.), take a look at Amazon CloudFormation.
I've currently got a base Windows 2008 Server AMI that I created on Amazon EC2. I use it to create 20-30 EBS-based EC2 instances at a time for processing large amounts of data into PDFs for a client. However, once the data processing is complete, I have to manually connect to each machine and copy off the files. This takes a lot of time and effort, and so I'm trying to figure out the best way to use S3 as a centralised storage for the outputted PDF files.
I've seen a number of third party (commercial) utilities that can map S3 buckets to drives within Windows, but is there a better, more sensible way to achieve what I want? Having not used S3 before, only EC2, I'm not sure of what options are available, and I've not been able to find anything online addressing the issue of using S3 as centralised storage for multiple EC2 Windows instances.
Update: Thanks for suggestions of command line tools for using S3. Was hoping for something a little more integrated and less ad-hoc. Seeing as EC2 is closely related to S3 (S3 used to be the default storage mechanism for AMIs, etc), that there might be something neater/easier I could do. Perhaps even around Private Cloud Networks and EC2 backed S3 servers, etc, or something (an area I know nothing about). No other ideas?
I'd probably look for a command line tool. A quick search on Google lead me to a .Net tool:
http://s3.codeplex.com/
And a Java one:
http://www.beaconhill.com/opensource/s3cp.html
I'm sure there are others out there as well.
You could use an EC2 instance with EBS exported through samba which can act as a centralized storage that windows instances can map?
this sounds very much like a hadoop/Amazon MapReduce job to me. Unfortunately, hadoop is best deployed on Linux:
Hadoop on windows server
I assume the software you use for pdf-processing is Windows only?
If this is not the case, I'd seriously consider porting your solution to Linux.
