Riak CS Lets Users Replicate Data Globally

'Net Features : wm-webhosting — Sat, 08 Dec 2012 14:46:00 GMT

Customers can now replicate Riak Cloud Storage (Riak CS) data across multiple data centers to assure its users that they can avoid disruptions from outages and serve content faster to multiple geographic locations, all while building upon its existing compatibility with Amazon S3. The cloud storage service from Basho Technologies will now allow customers to spread their stored data over a series of data centers located around the world, and the integration of the Amazon Web Services (AWS) infrastructure guarantees high availability. Basically, Riak CS customers will now be able to replicate their stored data on any data center they want on their own terms, in addition all of the benefits of using AWS, just to sweeten the deal. This solution also reduces some of the risks commonly associated with AWS. Moreoever, these new replication capabilities will break large data objects into smaller blocks that will be streamed to the underlying Riak cluster, where they will then be replicated for high availability. A manifest for each object will be maintained, allowing the service to retrieve each block from the cluster and present the full object to the end-user. Global information, bucket information and manifests will all be streamed in real-time from a primary implementation to a secondary site for multi-site replication, and objects can be replicated in either “full” or “real-time” sync modes. Riak CS, built upon Riak, the open source distributed NoSQL database...(read more)

Object Expiration Added to Amazon S3

Despite a rocky 2011, Amazon Web Services (AWS) continues to stand out among other cloud service providers. Recently, it added object expiration to S3 files, making it easier to manage temporary files/logs/etc. on Amazon S3.

Object expiration will allow developers to establish clear rules for automatically deleting files stored in S3. This addition follows up another new feature, multi-object deletion, which makes getting rid of multiple files (and other things) in an S3 bucket considerably quicker.

Unfortunately, multi-object deletion is capped at 1000 objects and must be done manually. Now, developers can set up guidelines for deleting files with a specific prefix, as well as the expiration period for objects (in days).

It should be noted, however, that Amazon warns about “a small lag between the expiration date and the date at which Amazon S3 removes an object,” but that it won’t charge for storage of objects past their expiration date.

Customers can start using the feature by going to the AWS Documentation site checking out the Working with Amazon S3 Objects developer’s guide.
