Exadata is a combined [https://blogs.oracle.com/exadata/exadata-why-and-what hardware and software platform] that includes [[Scale out|scale-out]] Intel [[x86-64]] compute and storage servers, [[RDMA over Converged Ethernet|RoCE]] or [[InfiniBand]] networking, [[3D XPoint|persistent memory]] (PMEM), [[NVM Express|NVMe]] flash, and specialized software.<ref name=":0">{{Cite web|last=Pedregal-Martin|first=Cristobal|title=Exadata: Why and What|url=https://blogs.oracle.com/exadata/exadata-why-and-what|url-status=live}}</ref>

Exadata was introduced in 2008 for on-premises deployment, and, since October 2015, via the [[Oracle Cloud]] as a subscription service, known as the ''Exadata Cloud Service''.<ref>{{Cite book|title=Oracle Database Exadata Cloud Service: A Beginner's Guide|last=Spendolini|first=Brian|publisher=Oracle Press|year=2019|isbn=978-1260120875|___location=Amazon.com}}</ref> Exadata Cloud@Customer is an on-premises implementation of Exadata Cloud Service, available since 2017. Oracle databases deployed in the Exadata Cloud Service or Exadata Cloud@Customer are 100% compatible with databases deployed on Exadata on-premises, which enables customers to transition to the Oracle Cloud with no application changes. Oracle Corporation manages this service, including hardware, network, Linux software and Exadata software, while customers have complete ownership of their databases.

==Use cases==

Exadata is designed to run Oracle Database workloads, such as an OLTP application running simultaneously with Analytics processing. Historically, specialized database computing platforms were designed for a particular workload, such as Data Warehousing, and poor or unusable for other workloads, such as OLTP. Exadata allows mixed workloads to share system resources fairly with resource management features allowing prioritized allocation, such as always favoring workloads servicing interactive users over reporting and batch, even if they are accessing the same data. Long running requests, characterized by Data Warehouses, reports, batch jobs and Analytics, are reputed to run many times faster compared to a conventional, non-Exadata database server.<ref name=":0" /><ref>{{Cite web|url=https://www.oracle.com/search/customers?Ntt=exadata&Dy=1&Nty=1&Ntk=S1|title=Exadata Customer Success Stories|access-date=July 16, 2018}}</ref><ref>{{Cite web|url=https://www.gartner.com/reviews/market/data-warehouse-solutions/vendor/oracle/product/oracle-exadata-database-machine|title=Gartner Peer Insights: Oracle Exadata Database Machine|last=Various|website=Gartner.com|access-date=August 8, 2018}}</ref>
