But still the scalability and performance of SDI services is reported to be crucial especially if they are accessed concurrently by a high number of users. Furthermore, laws and provisions such as the INSPIRE directive specify challenging requirements regarding the performance, availability and scalability of SDI services. This article presents a Hybrid Cloud architecture for matching INSPIRE-related Quality of Service (QoS) requirements, without investing in rarely used hardware in advance, by occupying external third-party resources on a pay-as-you-go basis. The presented Hybrid Cloud is a composition of a local IT-infrastructure (Private Cloud) and the computational resources of third-party vendors (Public Cloud). The local infrastructure is laid out to handle the average main load of a service and in lasting peak times additional resources of external providers are allocated and integrated on demand into the local infrastructure to provide sufficient service quality automatically. A proof-of-concept implementation of the proposed Hybrid Cloud approach is evaluated and benchmarked with respect to INSPIRE-related QoS requirements.
