Arsitektur Layanan Grid Terbuka
Open Grid Services Architecture (OGSA) describes a service-oriented architecture for a grid computing environment for business and scientific use. It was developed within the Open Grid Forum, which was called the Global Grid Forum (GGF) at the time, around 2002 to 2006.
Description
OGSA adalah interaksi terdistribusi dan arsitektur komputasi berbasis di sekitar layanan, memastikan interoperabilitas pada sistem heterogen sehingga berbagai jenis sumber daya dapat berkomunikasi dan berbagi informasi. OGSA didasarkan pada beberapa teknologi Layanan Web lainnya, seperti Bahasa Deskripsi Layanan Web (WSDL) dan Protokol Akses Objek Sederhana (SOAP), tetapi bertujuan untuk menjadi sebagian besar independen dari penanganan tingkat transportasi data.OGSA telah digambarkan sebagai penyempurnaan arsitektur layanan Web, yang dirancang khusus untuk mendukung persyaratan jaringan.
According to the "Defining the Grid: A Roadmap for OGSA Standards v 1.0", OGSA is:<ref>Defining the Grid: A Roadmap for OGSA Standards v 1.0</ref>
- An architectural process in which the GGF's OGSA Working Group collects requirements and maintains a set of informational documents that describe the architecture;
- A set of normative specifications and profiles that document the precise requirements for a conforming hardware or software component;
- Software components that adhere to the OGSA specifications and profiles, enabling deployment of grid solutions that are interoperable even though they may be based on implementations from multiple sources.
The Open Grid Services Architecture, Version 1.5 described these capabilities:<ref name="GFD80" />
- Infrastructure services
- Execution Management services
- Data services
- Resource Management services
- Security services
- Self-management services
- Information services
In late 2006 an updated version of OGSA and several associated documents were published, including the first of several planned normative documents, "Open Grid Services Architecture Glossary of Terms, Version 1.5".<ref>Open Grid Services Architecture Glossary of Terms, Version 1.5</ref>
The Open Grid Services Infrastructure (OGSI) is related to OGSA, as it was originally intended to form the basic “plumbing” layer for OGSA. It was superseded by Web Services Resource Framework (WSRF) and WS-Management.
