5 Intercloud and interoperability

• infrastructure capabilities type interoperability testing

• platform capabilities type interoperability testing
• application capabilities type interoperability testing.
As shown in Figure 1, there are three different target areas of cloud computing interoperability testing as
follows:
• "CSC – CSP", dealing with interaction between CSC and CSP
• "CSP – CSP", dealing with collaboration among different CSPs
• "CSP – management", dealing with CSP management functions.

Figure 1 – Target areas of cloud computing interoperability testing

Also, the cloud architecture in terms of the common set of cloud computing functional components are
described in [ITU-T Y.3502]. Figure 2 presents a high level overview of the CCRA functional components
organized by means of the layering framework.
