226 ITU‐T's Technical Reports and Specifications 2.1.1.1 Data/content center These are centralized repositories, for the storage, management, and dissemination of data and information organized around the objective of creating SCC. It is recommended that data warehouses use a platform that is scalable, reliable and high performance that allows for growth as the number of sensors installed is increased in the territory or/and the city. 2.1.1.2 Data center characteristics and the evolution of infrastructure architecture The infrastructure must be designed and provisioned including the specific volumetric considerations for supporting the business applications and considering the peak load transaction in jobs per second, availability and scalability requirements. When volumetric and projected growth do not manifest as envisaged, this method of sizing infrastructure computation and storage could lead to either undersizing or oversizing the footprint. Often, having such islands of computer infrastructure and storage, leads to underutilization of resources. This has a cascading effect on investment and effort spent on energy consumption, management overheads, software licenses and data center costs. Figure 6 – Data center infrastructure architecture: a conceptual view Figure 6 depicts a conceptual view of today's infrastructure architecture in a traditional data center. The surrounding data center components such as data centers facilities and legacy infrastructure would exist in this case, as individual components in the data center.
