“So, what do (people | applications) do ?”
Aims
To Predict Applications’ behavior and Users’ presence
To Combine the two to achieve the “situational awareness”
Approach
Data gathering of users at different levels
e.g., GPS trackers and GPS DAS FEST
Data gathering of applications
Cloud providers
Exploitation of MLDA solutions to build user and application models
Provide estimations for amount of users and application requirements

To Federate or not to federate ? Let’s Federate!
Aims
To achieve worldwide coverage
To enable the exploitation of heterogeneous providers
Ensure user satisfaction by means of federated resources
Approach
Incentivize the join to the federation
By letting the join option beneficial for cloud service providers
Advanced revenue sharing schema
Supporting cloud-across application execution
By providing a easy-to-adopt, standard-based solution for deployment using different cloud technologies
Supporting Federation-level SLA
Supporting Federation-level Monitoring
Supporting execution on edge devices

“I do not regard a BROKER a member of the human race” (Honore de Balzac)
Aims
Find best resources for the applications
Find solutions able to satisfy the needs of users and service providers
taking into account the available resources and the budgets of users
Approach
Federation-aware resource brokering
Application-level information exploitation
Leveraging user presence estimations
Definition of the applications and data replicas
Meta-heuristics to optimize the mapping

BASMATI Final Review meeting 14

15. BASMATI Final Review meeting
How does BASMATI provides such features ?
BASMATI brokerage is a complex activity, resulting by the interaction of four modules:
Resource Broker
To find the resources into the federation that satisfy a given query
Decision Maker
To leverage the information about users and applications, resources and costs to define a mapping schema linking applications and resources
Application Controller
To drive the application deployment (and adaptation) process of the applications
Federation Data Management
To optimize the data-plane of applications
