The collaborative scenario is introduced in Section 2.1, paying special attention to the architectural models as well as to the challenges posed when considering the fog–cloud collaborative model enriched with new strategies such as innovative resource sharing. Then, next section briefly introduces fog‐to‐cloud (F2C), as one of the proposed architectural contributions in this hybrid scenario, showing its main benefits in different verticals, also emphasizing some open questions remaining unsolved yet. Section 2.3 describes main F2C challenges (could be also applied to any F2C‐like architecture), split into three domains, research, industry, and business, in order to illustrate what the issues are on a large view for a successful deployment. Ongoing work done in well‐established fora is introduced next in Section 2.4, with the aim of providing users with pointers to main active efforts in the area. Certainly, as of today, this is a very active area; hence, many other relevant works are simultaneously running out there, as it can be seen after a light pass on the recent programs of highly reputed conferences or highly impacting journals. However, it is not the aim of this chapter to report all contributions dealing with all foreseen challenges, ...
