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

Comparison of The Oracle Public Cloud ( Database Service ) and Oracle on Amazon AWS (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 database license. In that respect service is similar to Amazon RDS. The Oracle Database Cloud is based on monthly subscription -"per user-per month or per environment-per month basis". Access to the database is likely to be at the level of an application database administrator i.e. you will only have access to "database schemas, application development tools, data loading services, Web Services APIs". Interestingly enough, it looks like you will actually  get access to a single schema only ("Each Oracle Database Cloud Service uses a single Oracle database schema. The Oracle schema provides full isolation for each individual Database Cloud Service." ), which is identical to Salesforce.com multi-tenant model. This is the same model that Larry Ellison mocked during The Oracle Cloud Service announcement at Oracle Open World 2011. In other words, you are not going to get the whole database for yourself, you will be sharing it with other users.

The Oracle Database Cloud will probably restrict your possible actions in database control arena in a greater degree than already fairly limited Oracle on Amazon RDS.  Oracle Public Cloud, is "all completely managed, hosted and supported by Oracle". This makes it suitable for roles where you do not care about the control of your database, but are more application focused and want to get database administration out of your way.

The precious oil is extracted from the seeds of prickly pear cactus plant. After taking out the seeds from the fruits, they are adequately dried and then cold pressed to obtain the oil. Indeed, the prickly seed oil is quite expensive. Well, that is understandable when you consider the fact that the seeds are really tiny and each seed contain only about 5% of oil in it at most, plus the seeds are usually handpicked from the fruits. This means it will take tons of these seeds to produce just one bottle of the oil for commercial purpose. But from its medical properties to its culinary importance, skin lightening, moisturizing, and protection abilities, down to its extraordinary hair care properties, prickly seed oil has got lots of excellent rewards for anyone who pays the price.
