Cloud Challenges

• Vendor Lock-in • Heterogeneity and lack of interoperability among different Cloud

providers

• Performance Variability:• Cloud performance can vary at any point in time• Unavailability problems exist even when 99.9% up-time is

advertised

Separation from provider-specific details

• Cloud Computing: manage your (many) infrastructures and your (many) platforms:• CCIM: concepts that are

independent even from the cloud.

• CPIM: cloud concepts that are independent of any cloud provider.

• CPSM: cloud provider specific details to specify how to run the system on a specific cloud.
