Smart City Stakeholders

Core Stakeholders

• Business Service Providers

– Operate business utilizing GSS

– Common objectives e.g., maximizing sustainability of their business -> impacting their business financials

• OEMs

– Produce equipment (source of energy consumption)

– Their efforts have significant impact on savings (e.g., via energy saving capabilities)

Core Stakeholders /2

• GSS providers

– Provide services to Business service providers

– GSS retain service interfaces

– Establish direct business relationsships with customers who need GSS

• GSS developers

– Implement business logic and optimization methods -> significant impact

– Domain knowledge required

Supporting Stakeholders

• Governments

– Are responsible for large scale sustainability activities and information providers

– Policy making and enforcement, legislation, standards

• Auditors

– Systematically assess GSS

– Provide baseline for comparing (future) GSS

– Standardized evaluation methods

• Service Consumers

– Currently “passive“, however, behavior patterns help to get data and improve GSS

Service delivery platform for Smart Cities

Service delivery workflows

Some GSS Requirements /1

1. Identifying Core Services – Collecting/Preparing data from target systems (access & acquire raw+higher

level data)

– Customizing for different target systems

– Accomodating various scales -> Elasticity

Elasticity ≠ Scaleability

Resource elasticity Software / human-based computing elements, multiple clouds

Quality elasticity Non-functional parameters e.g., performance, quality of data, service availability, human trust

Costs & Benefit elasticity rewards, incentives

Elasticity

Some GSS Requirements /2

2. Supporting Process optimization & analytics

– Data modeling & simulation, Context-aware controls, agent based systems

3. Supporting of sustainability policies

– Modeling & understanding policies of target systems

– Finding efficient ways for meeting goals

4. Ensuring Privacy & Security

– Securing controls for privacy & security

5. Supporting stakeholder collaborations

– Building interfaces and marketplaces for collaborations

First Conclusions

• GSS require tight integration from Requirements, Design & Implementation, to the Business Models

• Understanding & Support for Stakeholders needed (Data, Elasticity, collaboration models)

• Cloud service models and GSS collaboration models needed

Some Research Challenges /1

• Virtual Verticals

– Dynamic number of devices

– Various (amounts of) real-time data

– Ad hoc application usage on Clouds

• Cross-layer planning methodologies needed

– Providing an isolated environment per tenant

– Dynamic resources (Elasticity)

• Coherent model for scheduling/predicting resource usage

– Impact on Elasticity

Some Research Challenges /2

• Programing Model – Inherent in PaaS

– Decoupling applications from device specifics

– Control logic often executed in Gateways -> standardization issues

• Quality-aware real-time data – Data quality is highly volatile

– Data quality assurance is needed -> methods e.g. statistical, selective data sources, etc.

• Metering, Billing, and SLA – Needs support for all resources and various contexts

– Metering & Billing for all stakeholders -> Configurability
