The '''Simple API for Grid Applications''' ('''SAGA''') is a family of related standards specified by the [[Open Grid Forum]] to define an [[application programming interface]] (API) for common [[distributed computing]] functionality.

== Overview ==

The SAGA specification for distributed computing originally consisted of a single document, GFD.90, which was released in 2009.

== Scope ==

The SAGA [[API]] does not strive to replace [[Globus Toolkit|Globus]] or similar [[grid computing]] middleware systems, and does not target middleware developers, but application developers with no background on grid computing. Such developers typically wish to devote their time to their own goals and minimize the time spent coding infrastructure functionality. The API insulates application developers from middleware.

Line 23 ⟶ 21:

The specification of services, and the protocols to interact with them, is out of the scope of SAGA. Rather, the API seeks to hide the detail of any service infrastructures that may or may not be used to implement the functionality that the application developer needs. The API aligns, however, with all middleware standards within [[Open Grid Forum]] (OGF).<ref>T. Goodale, S. Jha, H. Kaiser, T. Kielmann, P. Kleijer, A. Merzky, J. Shalf, and C.Smith, A Simple API for Grid Applications (SAGA), OGF Document Series 90,http://www.ogf.org/documents/GFD.90.pdf</ref>

The SAGA API is designed to be extensible:defined a well defined mechanism exists to specify additional API ''packages'' which expand theits scope of the API as needed. The SAGA Core API itself defines a number of packages: job management, file management, replica management, remote procedure calls, and streams. SAGA covers the most important and frequently used distributed functionality and is supported and available on every major grid systems - XSEDE, EGI and FutureGrid. SAGA not only supports a wide range of distributed programming and coordination models but is also easily extensible to support new and emerging middleware.<ref>SAGA: A Simple API for Grid applications, High-Level Application Programming on the Grid
