Google App Engine high availability storage exits experimental stage

The High-Replication Datastore will allow applications to remain fully available during planned and unplanned downtime

The latest version of Google's SDK (software development kit) for its cloud platform App Engine includes the High-Replication Datastore, which has been generally available, the company said in a blog post on Tuesday.

An experimental version of the High Replication Datastore was introduced in January, following a six-month period during which there were reliability issues with the standard storage option, which Google wanted to solve more fundamentally, it said at the time.

When using the High-Replication Datastore, data is replicated across multiple data centers. This provides the highest level of availability, but comes at the cost of higher latency due to the propagation of data, according to Google.

One of the most significant benefits of the High-Replication Datastore is that applications remain fully available during planned maintenance periods, as well as during unforeseen problems such as power outages, Google said.

For applications that crave more CPU power or memory to serve requests, Google has also introduced two larger front-end instance classes, or virtual servers.

Three classes are now available -- with increasing memory, CPU limits, and associated cost. By default, applications use the most basic instance, which includes 128MB memory and 600MHz CPU.

Google has also added new experimental APIs. The Conversion API allows users to convert between PDF, HTML, text and images, while the Logs Reader API lets users build reports, gather statistics, and analyze requests, Google said.

The new SDK is available for Java and Python, and both are designated version 1.6.1. They can be downloadedfrom Google's website.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
