Exadata Database Machine Overview

The Oracle Exadata Database Machine is engineered to be the highest performing, most cost effective and most available platform for running Oracle Database. Exadata is a modern architecture featuring scale-out industry-standard database servers, scale-out intelligent storage servers, state-of-the-art 3D V-NAND NVMe PCI Flash storage servers and an extremely high speed InfiniBand internal fabric that connects all servers and storage. Unique software algorithms in Exadata implement database intelligence in storage, PCI based flash, and InfiniBand networking to deliver higher performance and capacity at lower costs than other platforms. Exadata runs all types of database workloads including Online Transaction Processing (OLTP), Data Warehousing (DW), In-Memory Analytics and consolidation of mixed workloads. Simple and fast to implement, the Exadata Database Machine powers and protects your most important databases and is the ideal foundation for a consolidated database cloud.

Exadata in the Cloud

The investment protection that Oracle has ensured through multiple Exadata generations on-premises, has continued with Oracle Database Exadata Cloud Service, and with Oracle Database Exadata Cloud Machine.

With Exadata Cloud Service, customers can now run Oracle databases in the cloud on Exadata, with the same extreme performance and availability experienced by thousands of organizations deploying Exadata on-premises. Exadata Cloud Service combines the world’s #1 database – Oracle, and the most powerful database platform – Exadata, with all the simplicity and operational flexibility of the public cloud. Oracle databases deployed in the cloud as part of this service include all Oracle Database options and features – such as Oracle Multitenant, In-Memory Database, Real Application Clusters (RAC), Active Data Guard, Partitioning, Advanced Compression, Advanced Security, etc. It also includes all Oracle Enterprise Manager packs.

The underlying design principle of Exadata Cloud Service is that Oracle databases deployed in this Cloud Service are 100% compatible with those deployed on-premises. This means that customers’ applications and data models do not have to change, ensuring a smooth transition to the cloud, and an efficient hybrid cloud strategy. They also do not have to invest in multiple cloud platforms for multiple workloads since Exadata provides a unified platform for all workloads – analytics, data warehousing, OLTP, consolidation, in-memory and mixed-workloads.

Exadata Cloud Machine takes this investment protection one step further by enabling a cloud-based Oracle Database subscription service available on Oracle Exadata, with all Database options and features, but deployed in the customer data center behind their firewall. Customers enjoy the benefits of agile cloud-based provisioning, while the associated Exadata infrastructure is maintained by Oracle.
