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.
