Enterprise cloud security features are finding their way into existing public cloud computing stacks
Google announced last week the end of the "experimental" availability of its high-replication data store; it's now a "real" part of the Google App Engine SDK. This is part of a key 2012 trend: Cloud providers will rush to address cloud computing concerns from enterprise IT -- including security, performance, and availability -- through the addition of features taken from existing private enterprise computing environments.
In the past, many cloud providers dismissed requests that features be added to replicate what existed in enterprise data centers. Typically, they referred to traditional enterprise computing methods as overly complex, convoluted, and costly. Indeed, many even gave this criticism a name: "enterprisey."
Now, Google App Engine can replicate data across multiple data centers, and thus work around availability issues in the case of maintenance and outages that affect a single instance. This offering is a result of businesses demanding such features before they move to the public cloud.
