Motivation
Evolution of GIS
29 June 2011 INSPIRE and Service Level Management
Desktop GIS Spatial Data Infrastructure (SDI)
� desktop- and data-centric applications
� proprietary and monilithic software
� higher internet bandwith
� new web service technologies
� many standardization efforts
� loosely-coupled architecture
� composed of open and interoperable web services
� retrieval, portrayal and processing of data over the web
� integration of live sensor data
Challenges
� Observations� Increasing amount of available data
� Increasing complexity of adopted algorithms
� Increasing number of potential users
� Emerging laws and provisions (INSPIRE)
� The Cloud Computing paradigm
� Highly competitive GIS market
� Example - INSPIRE View Service� 99% service uptime per day, week, etc. (Availability)
� 5 seconds initial service response time (Performance)
� 20 parallel service requests (Capacity)

Service Level Agreement
� Contract between service providers and service consumers� Cost-performance ratio transparency
� Monitoring promised service qualities
� Contract Lifecycle� Templates, Negotiation
� Monitoring, Evaluation, Reporting
� Accounting (usage costs, penalties)
� Key Elements� Key Performance Indicator (KPI)

SLA4D-GRID
� Service Level Agreements for D-Grid (2009 – 2012)
� Funded by German Federal Ministry of Education and Research
� 11 partners from science and industry
� Develop a SLA-layer for D-Grid
� Service and resource usage under given guarantees, service quality
requirements and pre-defined business conditions
� GI Demonstration Scenario
� Proof-of-concept of the SLA management framework
� INSPIRE Coordinate Transformation Service in the Cloud
