15 In a hybrid multi-VIM deployment with private and public cloud sites, it would
16 be advisable to allow a different strategy of image management for both types
17 so it is not mandatory to upload images to the public cloud, since:
18 - Public cloud often has a set of pre-loaded images (e.g. AWS’s AMIs) that
19 could facilitate their immediate consumption to users.
20 - Uploading a big image to public cloud might lead to relevant charges from the
23 Those public cloud images often have their own identifiers, checksums, etc.,
24 different from the ones for an image in public cloud.
26 The request is to extend the IM for VNFD so that:
27 - The current image reference is interpreted as the default image reference for
29 - Allow, as option, to include references to alternative images for specific
30 types of VIMs, that would be used for sites of that VIM type instead of the
33 ## Demo or definition of done ##
34 - Create a VNFD with a VDU that has a default VM image and a specific image for
35 a particular type of VIM (e.g. AWS).
36 - Create a NSD that includes the VNF above.
37 - Create instances of the NS in 2 different VIM, one of them of the type
38 specified in the VNFD.
39 - Check that both of them work properly.
