Amazon will offer Oracle Database 11g on RDS which brings patching, backup, replication, and failover support to Oracle’s database.
Oracle has provided for some time a good number of specific Amazon Machine Images (AMI), most of them being based on Linux and Database 11g, but Amazon intends to offer Oracle Database 11g as part of their Relational Database Service (RDS). That means that Amazon will take some of the administration burden off user’s shoulders such as updating the database with patches when available, backing it up and storing backups, scaling out via API calls, creating a replica in a different availability zone and keep it running to failover in case it is needed, creating read replicas in different zones for heavy-read workloads.
Amazon plans to offer three types of licensing:
Amazon has not said yet how much pay-by-hour means, but the fees for using MySQL on RDS could represent a reference, expecting higher prices for Oracle DB 11g. A MySQL DB Instance running on demand in US North Virginia costs between $0.11 and $2.60 per hour, depending on the size of the instance, while the storage costs $0.10/GB/month, and the IO costs $0.10 per 1M requests. There are additional costs for transferring data in/out of RDS.
Oracle will provide support for BYOL customers, while Amazon will provide support for On-demand and Reserved Instances, getting help from Oracle when needed. Amazon plans to deliver the service during Q2 of 2011.

A common “best practice” for unit tests is to only write a one assertion in each test. I intend to question this advice by showing that multiple assertions per test are both necessary and beneficial.
