Challenges in Cloud Computing
Summary and Conclusion
Networking of Information
No common persistent naming scheme for information.
Information named relative to the box they are located
in, URL’s resolve to IP-address.
Moving Information = Changing it’s Name (”404” file
not found errors).
Mobility and multihoming for hosts and networks is
problematic due to semantic overload of IP-address.

Summary and Conclusion
Networking of Information (Contd..)
No consistent representation of information
(copy-independant).
No consistent ways to keep track of identical copies.
Different encodings (eg: mp3,wav) worsen problem.
Security is host-centric.
Mainly based on security channels (Encryption) and
trusting servers (Authentication).
Can’t generally trust a copy received from an untrusted
user.

NetInf meets Cloud Computing
Cloud-computing - a resource sharing paradigm
E.g, computing power, storage,. . .
Execute software on the web, pay-per-use (SaaS)
Platforms for building and hosting services (PaaS)
Deployment platforms (IaaS)
Focus on the resource and whats running on top
NetInf a networking paradigm / technology
Data-oriented networking paradigm
Focus on transporting and accessing data
Both very different in nature, but there are common
aspects.
