The traditional way of performing backups includes using Oracle RMAN in combination with media management layer software ( typically Netbackup, Tivoli or similar ), which writes backup data to remote robotic tape unit. Tapes are then stored offsite to a secure location. It is well known fact that tape media poses certain challenges in reliability and physical manipulation areas. Cloud-based backups' main attraction is that they are inherently disk based, always accessible, offsite and there are no capex expenditures. All tape related costs are thus eliminated. On the other hand new costs will be incurred for Cloud backups storage and service. Data is transferred over the public network i.e. Internet. Cloud based backups can be used for quick database refresh or duplication of source databases to any target environment. Practically you have an unlimited amount of s... (more)

The Oracle Database Cloud Service vs Oracle on Amazon RDS, EC2

The Oracle Database Cloud is Platform as a Service ( PaaS ) so it only makes sense to compare it to Oracle on Amazon RDS.  Oracle on Amazon EC2, on the other hand, is an IaaS ( Infrastructure as a Service ) offering, which gives you full control over the installation, features and actions around your database. Oracle Public Cloud will consist of a number of major services, the Oracle Database Cloud being one of them. Please refer here for a complete list  of services. One of the most interesting characteristics of the Oracle Database Cloud is that there is no need to  purchase d... (more)

Oracle RMAN, BMC Patrol Catalogs Hosted in Amazon Cloud

Oracle RMAN  (Recovery Manager) catalog database contains backup metadata for all enterprise wide Oracle databases. Each database backed up through RMAN needs connection to a central backup repository database. RMAN catalog  is purged and maintained by removing obsolete backup records, crosschecking with existing media etc. If central repository grows too big then backup performance will suffer since it will take too long for RMAN to locate metadata. Amazon Web Services gives us the ability to quickly and easily create either brand new RMAN catalog database or move an existing c... (more)

How to Move Your Oracle Databases to Amazon EC2 Cloud

Amazon Web Services EC2 Cloud is full scale public data center offering services that are in many aspects far ahead of ancient practices present in regular IT environments. Fast provisioning and virtually unlimited scale make old fashioned server procurement and installations look like what they are - past century's practices. This article will not deal with usual objections to cloud computing revolving around change management difficulties ( how to incorporate new environment into the existing IT infrastructure ), security, reliability, performance etc. since we think that all t...

Which Cloud Service Provider Should Host Your Oracle Databases?

Big shift towards Cloud environment has started. It is now clear that this change is similar in magnitude to the shift from mainframe to client-server computing two decades ago. Amazon Web Services is the pioneer and market leader in Cloud computing space. Other vendors are playing catch up and do not come close to the breadth and scale of AWS offerings. Services and features Amazon provides are quite extensive and cover many of the enterprise-class computing needs. APIs and command line interfaces are available for each service, which makes scripting and automation achievable. ... (more)
