Self-adaptive cloud-based applications
Cloud-based applications that self-adapt to changes in environment and requirements
s Technology for a better society
Dynamically adaptive systems
• Continuous design and adaptation
• Short-term changes in execution environment
• Long-term changes in system requirements
s Technology for a better society
s Technology for a better society
CloudML
• Domain-specific language (DSL) for modelling the provisioning and deployment of multi-cloud applications at design-time
• Models@run-time environment for enacting the provisioning and deployment of these applications at run-time
