Oracle Private Database Cloud at Cloud Connect next week

Oracle is a sponsor of the Cloud Connect conference being held in Santa Clara, California next week (April 2-5).  The conference includes workshops, keynotes, conferences, and an exhibition hall which is open Wednesday and Thursday from noon to six p.m. each day.

 If you're interested in Private Database Clouds, or any type of cloud for that matter, stop by the Oracle demo area and visit our Private Database Cloud booth.  We can talk about the benefits of private clouds, the different types of models to choose from, how they differ from public clouds, and a customer-proven approach to making successful transitions to cloud computing.  We hope to see you there!

Oracle RAC in Solaris 11 Zones

In database cloud deployments, companies host multiple databases for use by various internal groups (private clouds) or external clients (public or community clouds). Whenever multiple databases are deployed together on shared infrastructure, the solution must take into account the degree of isolation each database will require with respect to faults, operations, security, and shared resources.

In many database cloud deployments, Oracle Database features and options will provide the required isolation. This allows consolidating multiple Oracle databases natively onto a shared infrastructure, without the need for further isolation. In native consolidations, all databases share a single Oracle Grid Infrastructure. This approach is described in detail in the Oracle white paper "Best Practices for Database Consolidation in Private Clouds" which is posted on our OTN page.

Database clouds hosting databases with security or compliance considerations have higher requirements for isolation. These could include sensitive data with privacy requirements, or data from multiple companies who cannot be aware of each other (i.e., a public cloud). Such deployments may need to apply additional technologies or controls beyond those available in a native consolidation.

Implementing higher degrees of isolation can be accomplished by encapsulating each database environment. Encapsulation can be accomplished with physical or logical isolation techniques. Oracle recently certified 11gR2 RAC in Solaris 11 Zones,  which is an important capability for database clouds, because it enables strong isolation between databases consolidated together on a shared hardware and O/S infrastructure. We've just published a new white paper that describes the options and makes a detailed analysis of how Oracle Solaris 11 Zones efficiently provide encapsulation to Oracle database clouds.  To see how this technology set can be leveraged on SPARC SuperCluster, read about the Oracle Optimized Solution for Enterprise Database Cloud.
