Motivation

Architecture [1]

Metrics

• Minimial Viable Functional Requirements
• Quality of Service (QoS)
• Quality of Experiene (QoE)

Sustainablity Application Design Process (SADP)

1. State of the art, i.e., no carbon-awareness
2. Sustainability Awareness Annotate Microservices
   • with computational requirements
   • QoS constraints
   • power consumption metadata
3. Microservice Classification
   • Annotate relevance for overall Application
4. Microservice Enrichment
   • Designers provide different levels of Application usage, deployment and execution

Theory

1. State of the art
   • A={M,E}, with M being the set of Microservices and E the connections between those Microservices
2. Sustainability Awareness
   • R = {F,Q,S}
     • F := set of functional requirements, regarding the amount of resources
     • Q := set of quality related non-functional requirements
     • S := set of sustainability related non-function requirements (e.g estimated power consumption)

   • A.score = Sum(

     R_i

     /(

     R

     \cdot

     M

     )) A.score \in {0,1}

3. Microservice Classification
4. Microservice Enrichment

Business Process Model and Notation (BPMN)

• Decision Model and Notation (DMN)
