Data Services

• Objectives
• Movement, access and update of data resources
• Not specify the meaning of data (cf. information
  service)
• Types of data resource
• Data resource- any entity that can act as a
  source or sink of data
• Types
• Flat files
• Streams
• DBMS
• Catalogues
• Derivations
• Data services

7
Data Services

• Example scenarios
• Remote access
• Staging
• Replication
• Federation
• Metadata

8
Data Services

• Functional capabilities
• Transparency virtualization
• Client APIs
• Extensible data type support and operation
• Data location management
• Simple access
• Queries (Structured Access)
• Transformation
• Data update
• Security mapping extensions
• Data resource configuration
• Metadata
• Provenance

9
Resource Management Service

• Objective
• Management of the resources themselves
• Management of the resources on Grid
• Management of the OGSA infrastructure, itself
  composed of resources
• Model

10
Resource Management Service
11
Resource Management Service

• Level of interface
• Resource level
• Resources are managed directly through their
  native manageability interfaces (e.g. SNMP,
  CIM/WBEM, JMX)
• Management
• Monitoring, setup control, discovery
• Infrastructure level
• Base manageability model
• Represent resources as WS-Resources
• Manipulate through the standard Web services
  means
• Access to resource level of the resources
• Generic manageability interface
• Common to all services implementing OGSA
  capabilities
• Introspection, monitoring, creation, destruction,
  etc.

12
Resource Management Service

• Level of interface
• OGSA functions level
• Functional interface
• Expose resource management capabilities
• Manageability interface
• General manageability interface
• Management capabilities
• Infrastructure level
• OASIS WSDM
• Management of Web services (MOWS)
• Management using Web services (MUWS)
• Functions level
• Resource reservation, monitoring control, VO
  management, security management, etc.

13
Security services

• Objective
• Grid application must adhere to the
  domain-locally enforced policies
  cross-organizational agreement
• Implementation-agnostic
• Extensible
• Integratable

14
Security services
15
Security services

• Virtual community concept

16
Security services

• Capabilities
• Authentication
• Identity mapping
• Authorization
• Credential conversion
• Audit secure logging
• Privacy

17
Self-Management Service

• Objective
• Reduce the costs complexity of managing the
  system
• Preliminary stage in OGSA
• Basic attributes
• Service Level Agreement (SLA)
• Policy
• Govern the behaviors of Service Level Manager
• Derived from SLA
• Service Level Manager (SLM)

18
Self-Management Service

• Capabilities
• Service level management
• Monitoring
• Analysis projection
• Action
• Policy and model based management
• Entitlement
• Planning
• Capacity management
• Provisioning
• Analytics

19
Information Services

• Objective
• Efficiently access and manipulate information
  about applications, resources and services
• Relatively static data used for discovery
• Model
• Producers an consumers should be decoupled not
  required any prior knowledge of each other
• Not prescriptive on the data model for
  information

20
Information Services

• Functional capabilities
• Naming
• Discovery
• Message delivery
• Logging
• monitoring
