At Google I/O last week, Google announced that its Google App Engine High Replication Datastore (HRD) – its schemaless object data storage service – currently processes over 4.5 trillion transactions per month, has an uptime of 99.95 percent and stores over a petabyte of data. Today, the company announced that it is dramatically reducing the pricing for some Datastore features. Storing a gigabyte of data previously cost $0.24 per month, but the company has now reduced this price to just $0.18 per month.
In addition, Google is also reducing the prices for read and write operations on the service. Write operations now cost $0.09 per 100,000 operations (previously $0.10) and read operations cost $0.06 per 100,000 operations (previously $0.07).
The High Replication Datastore automatically replicates data across multiple Google data centers to ensure that it’s always available. Before launching its HRD solution in 2011, Google previously offered a more traditional Master/Slave replication topology, but this old system has been deprecated since 2012.
Google’s HRD also forms the basis of its newly announced Cloud Datastore – a NoSQL database that’s currently in preview. Cloud Datastore’s pricing is currently coupled to App Engine’s pricing, so its users will see the same price reductions. Google also offers Cloud SQL for developers who need access to a more traditional relational database.
