Why we focus on Inter‐Cloud computing?
Secure cloud computing for Lifeline Services
1. Various Quality requirements
 Availability (even in emergency situation), Latency,Bandwidth, Security, Cost, Green

2. Various Functional requirements
 To increase user benefits, quick delivery, etc.

Can “single cloud” satisfy everything?
“Inter‐Cloud computing” technologies is promising.

Lessons learned : The East Japan Earthquake
Flexibly reassigning resources among cloud providers
and network providers on a global scale Serious damage
on ICT facilities inthe disaster area

 Serious power shortage /rolling blackout in wide
area of East Japan

10Requirements for Inter‐Cloud computing[On demand system configuration across clouds]
 Search for available resources across clouds
 Rebuild cloud services in heterogeneous environment (different machinespecs, different OS and different hypervisor) Reconfigure networks (network within datacenter and network between
datacenters) dynamically[Integrated service operation across clouds]
 SLA and policy negotiations among clouds
 Centralized monitoring and auditing of services across clouds[Seamless service deployment for end users]
 Automatic rerouting / distributing user access Mutually exchanging information for tenant / end-user authentication
across clouds
