City systems are the key elements that allow municipalities to support relationships with citizens and
administrative systems. At this point, there are different transformation approaches. A pragmatic
approach of many cities to this transformation has been to make legacy systems coexist with new
cloud-based solutions (private, on-site or public) building an architecture based on microservices
and containers. Chapter 6 describes the city IT ecosystem in detail.

The city platform, the e-government platform, the municipal database and the geographic
information system would make up this basic core (city IT core) on which administrative information
services, citizen services, as well as interconnection services with other external stakeholders would
be developed.

Once the core IT ecosystem has been deployed, on this common infrastructure, the city could be
able to:

• Develop new applications of value for citizens and city officials.

• Develop smart applications and services on the city platform.
• Migrate legacy systems to the new architecture.

• Interconnect not migrated legacy systems to the city platform.

In low-resource environments, reducing costs, eliminating duplicate systems, and avoiding
inefficiencies in coordination tasks should be a priority, given that this would allow additional
resources to be obtained to advance in the transformation and digitalization of the services
provided to citizens.

Within the reference architecture described in chapters 4 & 6, the data-knowledge layer and the
common services-support layer of the City Platform allow functional blocks that can be used in the
design of applications and digital services for citizens, generating efficiencies and cost savings.
