Background

The paper argues that, despite advances in cloud portability via adapters, libraries, and containers, key challenges remain in achieving interoperability and seamless composition of services across providers—especially without their cooperation.

It calls for intercloud markets and new pricing/accounting mechanisms to make such federations viable.
