Information today is generated and consumed in unprecedented magnitudes. With every click, swipe, and transaction, massive amounts of data are collected, waiting to be harnessed for insights, decision-making, and innovation. Today, more than 80% of the data that organizations generate is unstructured – and the amount of this data type will only grow in the coming decades.

Identity and Access Management (IAM) is the beating heart of modern application security. This article explores the foundational concepts of IAM, the architectural and operational demands of modern systems, the critical role of consistency and correctness, and how distributed databases like CockroachDB are enabling a new standard of always-on, scalable, and globally distributed IAM.

Legacy mainframe systems have long been the backbone of critical finance, healthcare, and government operations. However, as technology evolves, these aging systems often become costly to maintain, challenging to integrate with modern applications, and inefficient in meeting today’s digital demands. Migrating mainframe databases and applications to modern platforms is increasingly seen as a strategic imperative, offering enhanced scalability, flexibility, and cost savings.

In the era of cloud computing, traditional centralized database architectures are increasingly giving way to more flexible and resilient distributed database architectures. Since the cloud is, by definition, a distributed system, the architecture of traditional relational databases frequently conflicts with the architectural needs of modern cloud-native applications: elasticity, horizontal scale, and separation of concerns.

In today's rapidly evolving digital landscape, traditional mainframe database architectures have unique challenges and considerations for organizations that rely on conventional mainframe databases. Mainframe databases, while robust and capable of handling substantial volumes of data and high transaction throughput, face limitations in scaling, integration with modern systems, and cost efficiency.
