Virtual Organization Definition • Grid Virtual Organization (VO) – – Set of resources (computers, storage systems) Distributed among participating organizations Available for use by a group of users Is defined by the grouping of resources plus the grouping of individuals, brought together for a common purpose under mutually acceptable governing rules.

Creating a VO • Hosts and users must obtain certificates • Users are then granted access to hosts (by the owners of the hosts). • The set of users coupled with the set of hosts they are allowed onto is what “defines” the VO U 1 OA C S C OB C C S S U 2 C C C C S S S VOX S C Storage Resource OC VOY Compute Resource Grid Tech Team September 15, 2003 5

CEOS Grid - CAs • CEOS Grid Users will not all have the same CA • We want to limit the number of CAs to the smallest possible set. – Makes management easier – Makes policy decisions easier • European users already have a high-quality operational CA • US Users are encouraged to obtain certificates from NASA IPG Grid Tech Team September 15, 2003 7
CEOS Certificates from NASA IPG • NASA Information Power Grid (IPG) already runs a high-quality CA that is accepted by most VOs. • NASA IPG is providing CA resources for the CEOS Grid. • Current status – Certificate request software has been delivered & tested. – Operating well at 2 test sites (II, SGT) and at GMU. – Others are encouraged to try it out. • Availability http: //grid-tech. ceos. org/gridwiki/Ceos.

Firewall Grid Tech Team September 15, 2003 12
General Firewall Issues • Using the Grid means that you have to make new services accessible to the internet – – • System administrators and security people will be uncomfortable with this Some sites have different policies, some are set up to allow experimentation outside the firewall What you can do 1. Familiarity - install & test on a machine outside the firewall, learn about the Grid 2. Provide information about security issues to people who need it 3. Develop a relationship with the people you depend on for access Grid Tech Team September 15, 2003 13
Firewall • Tech Team has put together a firewall document http: //grid-tech. ceos. org/gridwiki/Firewall. Best. Common. Practices • Contents – Introductory material • CEOS Grid overview; Quick primer on Grids; Globus port numbers – Site specific sections • Meant to be filled in by each site with anything you learned that might help someone else – Product specific info • Currently one - Cisco instructions – Miscellaneous • Open Questions; References; To Do Grid Tech Team September 15, 2003 14
CEOS Grid Toolkit Grid Tech Team September 15, 2003 15
CEOS Grid Components • Baseline (Core) – Globus 2. 4. 2 with latest bug-fix packages - see advisories page at: • http: //www-unix. globus. org/toolkit/advisories. html? version=2. 4 – Grid Packaging Toolkit (GPT) 2. 2. 9 – IPG Certificate Authority Package 0. 0. 3 – EU Data Grid 2. 0 (being used by ESA) • Globus 2. 4 • Other Dependent Packages – Java Community Grid Kit (Java Co. G) 1. 1 – Other COG’s (Perl/Python) Grid Tech Team September 15, 2003 16

Grid Components we’re Tracking • Globus 3. 0 • Metadata Catalog Service (MCS) (Current version as of 8/11/03) – Open Grid Services Architecture – Data Access & Integration • (OGSA DAI 2. 5 - http: //www. ogsadai. org. uk/) – Community Authorization Service (CAS) Alpha R 2 Release • OGSA DAI 3. 0 – Ported version of MCS – planned • MCS with Spatial Query capabilities – planned • Storage Resource Broker/Metadata Catalog (SRB/MCAT) V. 2. 1. 2 – Globus Grid Security Infrastructure (GSI) Grid Tech Team September 15, 2003 18
CEOS Grid Toolkit • WGISS participants are developing higher-level tools & components • GMU – – OGC WCS with Grid. FTP back end OGC WCS with Grid front end OGC Catalog wrapper on Grid MCS Reprojection service, 13 NASA EOS projections • ESA – – Grid Engine - multi-Grid job management Web Notification - Grid-to-Web events Grid Portal - Web control of Grid applications Reprojection Service Grid Tech Team September 15, 2003 19
CEOS Grid Toolkit Catalog • We need to put some thought into how we want to describe the components. • Possible metadata elements (thanks to Stu Doescher): –short name –long name –summary description –pointer to additional discussion –latest version and date –maturity - new, obsolete –other parts needed –recommendations –Contact points • supported and by who • used by –Technical parts • Language • how to install • problems Grid Tech Team September 15, 2003 20
