Is it possible to get object metadata with spring-aws-s3 library? I need access to "ETag" header but as it seems like SimpleStorageResource does not expose way to access objectMetadata and ResourceLoader interface does not expose connection.
What are my options? Just use S3 SDK directly?

When trying to call the OData service (in our example the BusinessPartnerService) on the S4 instances we have we are getting the error as seen in ref6 and ref7. However, if we are calling the API via a browser with the same credentials we can retrieve data from the system.
We want to understand what is causing the error and how to configure the connection in the cloud foundry environment correctly.
The full configuration of the system can be discussed and shown during a web session.
I tried to look around but couldn't find enough details on how to programatically get list of all services that my aws account is currently using.
Something like: EC2, S3, DynamoDB..etc
Is there a Java API or AWS CLI solution that I can use?
AFAIK there is no AWS service that exposes that information programatically. However if you're after this information for cost purposes there is the AWS Budgets service that allows you to setup budgets for your AWS resources - it has a public API which is accessible from Java and the CLI.
I am new with Software defined storage. I was working on possible ways of integration of different object storage implementations like AWS S3, Openstack Swift with Ceph.
I am wondering if I can use ceph API calls to store objects in Openstack swift?
The document here specifies that I can use Swift APIs to store objects in ceph (OSDs), but is it possible the other way around?
Thanks for any help in advance.
Exaclty. Ceph Rados Gateway is a full replacement of Swift Object storage with some missing functionality as described here.
http://docs.ceph.com/docs/master/radosgw/swift/
To make it clear, in order to store objects in Ceph Cluster you should just setup Rados Gateway and that's it. You will have two options to operate either using Swift API or S3 API.
Rados Gateway also supports S3 API to store objects. You can even configure RGW to access containers like S3 bucket subdomains. Ex: #bucketname#.s3.example.com
I got to know that Rackspace Cloud Files is based on OpenStack Object Storage service (Swift).
As OpenStack allows configuring/manipulating object storage using S3 APIs through swift3
http://docs.openstack.org/trunk/openstack-object-storage/admin/content/configuring-openstack-object-storage-with-s3_api.html
I am thinking whether Rackspace Cloud Files provides S3 API support as well. I have a client written for Amazon Web Services using S3 RESTful APIs so was thinking to reuse it for Rackspace Cloud Files as well.
The S3 plugin for Swift is not deployed as part of Rackspace Cloud Files (most production deploys of openstack don't deploy it by default). However, if you want better flexibility in the app, you can use a cross cloud toolkit such as libcloud (python), fog (ruby), jclouds (java), pkgcloud (node/js). This means you can use a simpler abstraction and support multiple providers within your application.
I'm trying to enable bucket versioning using the .net amazon sdk. I was wondering if anyone could shed some light on it.
There's a specific method that can be called to enabled this in the SDK.
