                         flexible and resource efficient resiliency from link failures in 
                         the optical cloud environment. However, when a failure affects a 
                         node hosting a datacenter (DC), service relocation from the 
                         affected DC is not possible. One alternative to protect against DC 
                         failures relies on using design strategies that duplicate the IT 
                         (i.e., storage and processing) resources in a backup DC at the 
                         expense of increasing resource overbuild (i.e., cost) of the 
                         network. This work proposes a dimensioning strategy based on the 
                         shared-path shared-computing (SPSC) concept able to protect 
                         against any single link, server, or DC failure scenario with 
                         minimal resource overbuild for the network and IT infrastructures. 
                         SPSC is based on the intuition that only storage units need 
                         complete replication in backup DC, while processing units can be 
                         instantiated only after the occurrence of a failure, leaving the 
                         design strategy some leeway to minimize their number. As result, 
                         the proposed SPSC design shows a considerable reduction in the 
                         amount of backup resources when compared to the dedicated 
                         protection strategies.",
