Use Cases and Deployment Scope

One of the motivations for using Oracle Exadata is its availability on AWS as a cloud service. Oracle Exadata service is available on AWS as the Oracle Database@AWS service. Because we are already using Oracle RAC in the On-premises Data Center, we wanted similar multi-node Oracle RAC availability in AWS/Azure. We have been using the Oracle database features extensively in our products. With growing customers, data, and transaction volumes, we are seeing Exadata as a workload beast that provides the best Oracle database performance optimization. Because Oracle Exadata comes with a large number of machines and storage, database consolidation has been another reason to choose it.

Pros

Engineered system, well optimized for running Oracle database.
High Availability and Scalability.
Database Performance.
Huge size of Hardware like CPU, RAM and storage.

Cons

Exadata comes as an appliance so doesn’t support much customization.
I couldn’t install the latest python version on this machine.
Better Oracle support.

Return on Investment

Provides Oracle RAC capability running in the Public cloud like AWS, Azure.
Best-in-class appliance to run the Oracle workload, which provides performance, scalability, and high availability.
However, Exadata is expensive very service, it takes several years to get ROI.
One should be careful about moving to Exadata, as most use cases can be solved with Oracle RAC.

Use Cases and Deployment Scope

Various database servers for Healthcare applications. Use cases span from typical transactional systems to data warehouse and analytics. Important criteria: database performance, data safety, 24x7 non-stop operations, High Availability. These are critical for real-time applications serving customers in healthcare industry.

Pros

High speed of SQL operations due to a unique design of Exadata with offloading of SQL processing to storage cells
Built-in High Availability of a DB server due to it's base architecture of a multi-node Oracle Real Application Cluster
High overall sever performance due to its use of a proprietary "Smart Cache" feature utilizing a high speed flash memory
Excellent scalability of a DB server by adding cluster nodes as well as expanding it into a network of serially connected clusters

Cons

The process of patching and upgrade of Exadata server components could be improved with a goal to minimize the overall effort, make it fully automated and transparent.
Improved guidelines and possibly more sophisticated tools for sizing of new Exadata servers for migration from old legacy hardware.

Return on Investment

One of the central critical systems was migrated from a large 4-node Oracle RAC running on legacy hardware. This application was experiencing severe performance issues literally causing loss of service for numerous customers. Once it was migrated to a 2-node Exadata server, its average performance improved almost by a level of magnitude, therefore eliminating any signs of application slowness.
Numerous application databases were migrated to Exadata servers which reduced the overall cost of hardware due to Exadata's price structure.
