A city is a system of systems with independent objectives and governance for transportation, energy, healthcare, safety, security, and infrastructure. A smart city relies on data to be the connectivity between independent functions, and open data to be the building blocks for citizen-centered design, inclusion, and sustainability. Big Data is not about size – it is about finding new life-changing and transformational opportunities using data. From Smart Mobility and Smart Energy to improved Public Health, Safety, & Governance – this session will discuss how cities are delivering better citizen services leveraging open source technology with a consistent governance and security framework that spans the data center and the public clouds. Data integration is the key to ensuring that a city’s attempts to become an intelligent system of systems doesn’t result in a system of silos. A single view requires the capability to integrate transactional data from traditional data stores with person generated data, unstructured data, and machine sensor (IoT) data. The key to managing such a range of data is a capability that allows for both scaling analytic workloads and the preservation of detailed data with unexplored value, as both are vital to future growth potential. Key Takeaways: Understand the common use cases that tier 1, tier 2, and emerging cities are undertaking to deliver tactical results and progress towards policy objectives. Understand the role of a shared catalog, unified security and consistent governance in building a secure, trusted, and connected capability.
