ASM brings the clustering, pooling, sharing, and dynamic adjustment of grid computing that we’ve been talking about to the area of database storage. * * * You may have heard about Oracle’s most recent hardware offering, the Exadata database machine. This is world’s highest performance database machine along a number of dimensions. It is also an important option for enterprises looking to create a private cloud on consolidated infrastructure. Performance Facts… #1 in I/O Throughput – Up to 65 GB per second (uncompressed data) – scans can now access disk and flash simultaneously, going beyond 50 GB per second of Flash-only. #1 in I/O Rate – Up to 1 million I/O’s per second (full rack) #1 in Compression – 3x to 15x data compression (we have seen over 70x compression on some data sets) * Ok, let’s turn to our second major requirement, component sharing. * A definitive and important distinction between IaaS and PaaS is that the platform provides a number of components for cloud tenants to use in creating their applications. These components are unique to each domain, enterprise, and cloud and thus are custom-built, though with significant help from the Oracle PaaS Foundation as we’ll see in a minute. These are created by the Central IT function. There are three basic kinds of platform-based components. [click] The first include components that will be embedded in the tenant app (e.g. code that is copied into an app). The second consists of services that are already up and running and get connected and called into by the tenant app—these are things like SOA services. The last category is like the first but sort of inverted: The component is a nearly complete app that only requires minimal additional customization to turn it into a full app. You could think of this as an app shell or an app chassis. * * Creating SOA services and BPM processes as reusable components is straightforward with Oracle SOA Suite and BPM Suite.
