Can PostgreSQL pickup where MySQL left off?

EnterpriseDB, a provider of enterprise-class products and services based on PostgreSQL, today announced Postgres Plus Cloud Server, which the company has billed as "a full-featured, Oracle-compatible, enterprise-class PostgreSQL database-as-a-service for public and private clouds with support for Amazon EC2, Eucalyptus, Rackspace, and GoGrid."

We've seen other database-as-a-service offerings come on the scene from the likes of Salesforce.com's Database.com, Amazon RDS, as well as from startup Xeround. But they're not based on PostgreSQL, which has had years of hardening and development by a committed community. The other databases are not "Oracle compatible," … Read more

Availability, elasticity, and cloud databases

The Amazon Web Services outage in April created uncertainty about the reliability of the cloud. And while the outage may have cast doubt about its ability to handle mission-critical applications, Xeround CEO Razi Sharir, whose MySQL cloud database-as-a-service goes into general availability today, sees the event as an opportunity to better understand the unique characteristics of the cloud environment--namely availability and elasticity.

Via an e-mail interview, Sharir maintained that high availability in the cloud is different from maintaining availability in a traditional data center because there is limited control over the cloud infrastructure. He notes that in the cloud, high … Read more

Are databases in the cloud really all that different?

Last week a discussion emerged in regards to the necessity of the NoSQL moniker associated with a new wave of open-source distributed database projects like CouchDB, MongoDB and Cassandra.

CouchOne, the commercial entity behind CouchDB even announced that it's moving away from associating the company with NoSQL as focuses on enabling offline data and applications.

The current orthodoxy would have you believe that if you are trying to get your head around "big data" or "Web scale" (see video), NoSQL is the answer. If you are dealing with preset data definitions being accessed by all … Read more

Xeround scales MySQL for the cloud

Today, Xeround officially announced the release of the private beta of its "MySQL for the Cloud" service--an elastic, linearly scalable, relational database designed to run applications in cloud environments.

Xeround is based on an in-memory database and has been tested in a number of telco production environments, according to CEO Razi Sharir. The software utilizes virtual partitions where data partitions are decoupled--or abstracted--from physical resources. These virtual partitions hold copies of both the data and the indexes, in order to ensure high availability and performance.

Despite the ubiquity of open-source MySQL, the database has in the past suffered … Read more
