It is important to note that both custom built applications and traditional off-the-shelf applications such as Oracle E-Biz, PeopleSoft, Siebel, SAP etc. benefits from Oracle RAC availability and scalability features. ![RAC Family of Solutions](./images/racandassociated.png " ") ## RAC and MAA Oracle MAA is a collection of architecture, configuration, and life cycle best practices and blueprints. It provides Oracle’s customers with valuable insights and expert recommendations which have been validated and tested working with enterprise customers. This is also an outcome of ongoing communication, with the community of database architects, software engineers, and database strategists, that helps Oracle develop a deep and complete understanding of various kinds of events that can affect availability or data integrity. Over the years, this led to the development and natural evolution of an array of availability reference architectures. -RAC is a key underpinning of MAA. +RAC is one of the key technologies for MAA. ![Oracle Maximum Availability Architecture](./images/maa_overview.png " ")
