In-memory cache for the cloud: Amazon ElastiCache

In-memory cache for the cloud: Amazon ElastiCache
With Amazon Amazon ElastiCache supplemented its cloud services to a
style similar to memcached in-memory cache. Here, stored data will be
used to read much faster than hard disk drives, which should increase
the performance of Web applications.
For his ElastiCache Amazon provides several nodes available, with
between 1.3 GB and 68 GB of memory and having 1 to 26 ECUs (Elastic
Compute Unit, here spread over 1 to 8 virtual cores). Prices start from
U.S. $ 0.095 per hour on the smallest available cache node.
Multiple cache nodes can be summarized as ships in a cache cluster, each
cluster (if several) of AWS availability zone is allocated. Individual
nodes can be as needed to remove it or add to the cluster. Each node
also gets its own DNS name assigned to the above it can be addressed.
Memcached as a cache engine currently in version 1.4.5 is used.
Accordingly, Amazon could be fully addressed ElastiCache compatible
Memchached. Applications that use memcached for caching, should thus
benefit without further adjustments in the Amazon cloud in-memory
caching. All settings related to caching, protocol, algorithm and
strategy are summarized for each type and version of the caching engine
parameters in a cache group. This would enable different cache nodes
operate with different settings. Further details also provides Amazon
Web Services blog.
Amazon ElastiCache is initially as a beta version and only in the U.S.
East region available, Amazon wants to expand the service in the coming
months, however, on further AWS regions.
