Infrastructure layer

Massonet Philippe, CETICRESERVOIR Dissemination Activity Leader

John Kennedy, INTELSLA@SOI Infrastructure Leader

• Service oriented economy – Market of services– Reduces complexity and cost– Requires a service oriented infrastructure

• Approach: Infrastructure as a service

– Map business level requirements into infrastructure SLA

– Service provider (SP) uses infrastructure on demand

– Infrastructure provider (IP) provides infrastructure as a service, on demand

Valencia, 12 and 13 April 2010 NESSI Projects Summit

Motivation and Objectives

Driven by 4 grounded use cases:– ERP Hosting– Enterprise IT– Service Aggregation– eGovernment

Delivering the SLA@SOI Framework:

– Spanning the entire services stack - business through software to infrastructure

– Almost entirely Open-source– Driving Open standards

A Dependable Cloud- through SLAs

Infrastructure Layer

Bounded by Infrastructure SLA Template– Describes all supported configurations, monitoring, service levels

Conforms to SLA Model– Rich– Comprehensive– Extendable

Multiple Formats Supported– XML– WS-Agreement– BNF for human legibility

Scope Includes – Technical Provision Request details– Monitoring requirements– Functional and non-functional parameters

Infrastructure as a Service

• SP responsibilities– Defines the deployment with a service manifest – Defines elasticity– Monitors the deployment– Administers the deployed VM

• IP responsibilities– Manages the physical and virtual infrastructure

• Placement of VM on physical machines in optimal way such SLAs are satisfied• Elastcicity: scale up and down

End of Deployment

Scenario

• Status– Prototype developed– Architecture, interfaces, model defined– Use case scenarios elaborated– Refined implementation in progress– Use case integration begun (ERP, Enterprise IT, Service Aggregation, eGovernment)

• Results– Draft OCCI Standard published by OGF– Initial use case deployment feedback available Summer 2010– Will trigger initial publication of software open-source

• For More Information– http://www.sla-at-soi.eu– Includes publications, public deliverables, use case scenarios
