Oracle Cloud offering - What makes it unique ?

Three things that make Oracle cloud offering unique:
1. SaaS, PaaS and IaaS offerings
2. Private and Public cloud offerings
3. Ability to seamlessly move between private and public cloud

RISC to x86 migrations - Or CISC to RISC

Migrating from RISC based systems to x86 (CISC based systems) is another type of cloud migration along with application, database, and mainframe z/OS migrations. However, the steps, best
practices, process, methodology, and tools used are the same. The components of the current RISC based architecture that need to be migrated remain the same:
1. On line application
2. Batch application
3. Integration Infrastructure
4. BI and reporting
5. ETL processing
7. Operating System
Note on OS migration: Although an operating system migration is often assumed (UNIX to Windows/Linux) in a RISC to x86 migrations, this does not necessarily need to be the case as Solaris and HP-UX (announced) run on x86.
It may also be the case you are already running Linux on your RISC system so there is no need to migrate the OS. However, you will probably be upgrading to a
newer release of Linux.
8. Operating System scripts and tools
9. Application, network, database and operating system management and monitoring products and tools
10. Other infrastructure software such as DR, replication servers, gateways, back up and recovery ....
11. Hardware refresh - Of course, you will need to purchase, install, configure and test the x86 based hardware platform. This is a great opportunity to consider hardware infrastructure that is
better suited to the cloud such as blades (Dell, CISCO UCS, Sun/Oracle) or engineered systems (Exadata and Exalogic).
Ultimately the question is how long will it take, what are all the activities involved, and how much will it cost. The answer to these questions is based more on the OS migration that is being done
then the move from RISC to x86. Will the application language or 4GL product run on Linux/Windows? What is the impact of moving the database from one OS to another ? (this should be minimal as all major relational databases run on x86). The biggest impact (for the application migration) could be Unix specific KSH or CSH scripts. You may also be running management, monitoring, or older job scheduling tools that
only run on UNIX/RISC.
As you can see, nothing is different here from what I have blogged about regarding mainframe, client/server, and application cloud migrations.
Intel has a comprehensive RISC migration white paper here:

Oracle cloud migration success starts with design

Article on TechTarget is an excerpt from the Migrating to the Cloud book. This excerpt discussing the approaches that can be taken to cloud migrations.

Appliance, engineered solutions are becoming the industry rage

HP Enterprise Database Consolidation Appliance for SQL Server really demonstrates how Oracle has set the stage for engineered solutions / appliances becoming the next big wave in the enterprise IT industry:
The article mentions how the HP/Microsoft announcement is clearly a response to Oracle Exadata. However, from a technical perspective, it is a much different offering than Oracle Exadata. The HP/Microsoft
offering is all about consolidating by offering a preconfigured database and hardware solution using hypervisor based virtualization. Oracle Exadata is all about a preconfigured data and hardware solution for
consolidation but also focused on high performance.

Mainframe as the cloud ?

Everyone seems to jumping on the 'new' (not new at all) idea that a mainframe can be used in the cloud. SD Times article in October 2011 states: "While datacenter utilization can be tricky to optimize above 30% even with virtualization and workload tools, mainframes tend to run at over 80% of capacity."

Forth Key attribute of Cloud Computing - Provisioning

Provisioning the system from end to end - OS, hardware, storage, application, network and datavase need to be self service provisioned. Provisioning is dynamic and self-service provisioning of applications involves deploying applications to your cloud infrastructure with a few mouse clicks. So, when moving to the cloud, application provisioning will be made easier since there are not hundreds or thousands of client machines to deploy too. Self-service provisioning of computing infrastructure in a cloud infrastructure is also very desirable as it can cut down the time it takes to deploy new infrastructure for a new application or scale up/down infrastructure for an existing application. Public cloud service providers like Savvis, Terremark, and AT&T all have self-service portals where users can sign up for cloud services and their compute infrastructure is ready within hours for usage. Oracle Enterprise Manager provides many Application Programming Interfaces (APIs) that can be incorporated into the self-service portals of cloud providers to automate the provisioning of compute infrastructure for Oracle products such as Oracle Fusion Middleware and Oracle database.

SSD used for robust applications

Interesting article as flash is a key component of Oracle Exadata, Exalogic and new Superclusters.
Flash to achieve high performance
However, this article is about using flash for a 'regular' Oracle database.

Physical Vs Virtual in enterprise data centers / private cloud

Interesting article that discusses physical Vs. virtual enterprise data centers. The article discusses physical (Oracle Exadata) data centers. May companies deciding dedicated physical appliances are the best choice for big data applications.

Oracle Database Appliance - Cloud 'in a box' for small to mid-size companies ?

Seems logical for Oracle to announce a database appliance for small to mid-size companies as Exadata was too big for these companies: This announcement reminds me of an information week article I just read titled "Appliances: Just How Many Toasters Do You Need?'. The article discusses the need for both virtualization and specialized software/hardware appliances. Article also discusses Oracle Exadata or mainframe for large database workloads. Now there is a new 'toaster' for small and medium size database workloads.
