Overview
On March 27, 2012 Basho announced a new product called
Riak CS
On March 20, 2013 Riak CS became open source
Riak CS is... enterprise cloud storage Riak S3-compatibility multi-tenancy per
user reporting built on top of large object storage
Enabling you to host your own PUBLIC PRIVATE & CLOUDS
or…. Reliable Storage Behind Apps
About Riak
Riak Dynamo-inspired key/value store Written in Erlang with C/C++ Open
source under Apache 2 license Thousands of production deployments
Riak High availability Low-latency Horizontal scalability Fault-tolerance Ops friendliness
Riak Masterless • No master/slave or different roles • All
nodes are equal • Write availability and scalability • All nodes can accept/route requests
Riak No Sharding • Consistent hashing • Prevents “hot spots”
• Lowers operational burden of scale • Data rebalanced automatically
Riak Availability and Fault-Tolerance • Automatically replicates data • Read
and write data during hardware failure and network partition • Hinted handoff
How It Works

Large Object Riak CS S3 API Reporting API Riak CS S3 API Reporting API Riak CS S3 API Reporting API Riak CS S3 API Reporting API Riak CS S3 API Reporting API 1. User uploads an object 1 MB 2. Riak CS breaks object into 1 MB chunks 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 1 MB 3. Riak CS streams chunks to Riak nodes 4. Riak replicates and stores chunks
USERS multi-tenancy: Riak CS will track individual usage/stats access_key secret_key
users identified by users authenticated by
BUCKETS users create buckets. buckets are like folders. store objects
in buckets. names are globally unique.
OBJECTS stored in buckets. objects are opaque. store any file
type.
