- Vendor-specific Platforms: Smart city platform from leading vendors like IBM and Cisco address many areas like water, energy, and building. These are horizontal solutions encompassing many proprietary technology solutions bundled together.
- Niche Solutions: On the other end of the spectrum, there are solutions targeting specific area and focusing on providing specific solutions. E.g. Eutech Cybernetic for smart workplace solutions, Petra Systems for smart lightening and smart surveillance, etc.
- Every vendor has its own proprietary standards for communication and data. Large platform-like implementations are typically slow in adapting new industry standards since it involves complex release cycles. Even if government defines certain standards, such implementation cannot comply with it immediately.
- Proprietary solution would use its own data center. There is increasing need for environment-friendly co-located data centers for smart cities. Since there is no standardization of data storage,this will result in islands of smart data clouds located worldwide.
- Smart city technologies are relatively new and their scaling with large amount of data is unproven yet. Many point solutions for specific services will end up being an expensive proposition for a city. Patchwork of expensive and un-scalable solutions in smart city realization poses a big threat to achieve true value of such efforts.
