1.1 In-memory data grid for efficient processing of large volumes of data in a manner appropriate to the characteristics of your IT system
Hitachi Elastic Application Data Store (abbreviated hereafter to EADS) is a data processing infrastructure product for configuring an in-memory data grid. An in-memory data grid is a data processing infrastructure that distributes a large volume of data to multiple servers' memory for the purpose of efficient processing of that data.
Today's social environment is undergoing rapid changes that are being driven primarily by advances in IT technology - especially in the development of Internet technology and in the expansion of services being deployed on the Internet. The widespread use of high-performance mobile devices, such as mobile phones and smartphones, has made these changes happen at unprecedented speeds.
With the evolution of the social environment, the amount of data handled by IT systems has increased exponentially. Users desire fast response times even during peak access periods, and they might wish for servers to be added temporarily in response to fluctuations in the volume of data and the number of accesses.
It has become difficult to satisfy such demands with IT systems that use only a relational database management system (RDBMS) to manage data.
Data processing infrastructure software products based on a different concept from conventional RDBMSs are now attracting attention, such as in-memory data grids. These software products, which are often called NoSQL (Not Only SQL) databases, complement RDBMS.
With the advent of NoSQL, you can now satisfy various needs by combining an RDBMS and complementary software products, rather than by relying solely on an RDBMS for all data management tasks.
EADS provides a data processing infrastructure that complements an RDBMS by configuring an in-memory data grid that provides both high scalability and high reliability.
