Alex Babeanu, an Identity Solutions Architect at Nulli, discussed his work with graph databases like Neo4j in managing identity and access management (IAM) complexity. With the exponential increase in identities due to smartphones, online services, and smart devices, graph databases bring sanity to this growing problem. Babeanu's team uses Neo4j for system integrations and designing solutions, finding it essential for modeling interconnected identities and deriving access policies. He attributed his choice of Neo4j to its ability to handle the dramatic increase in identities, which is a nightmare to manage with traditional methods like LDAP or SQL databases. Babeanu found Neo4j's simplicity in transforming complex requirements into manageable models fascinating. As he believes that graphs and AI will be crucial moving forward, particularly in IAM, he envisions a future where these technologies will become even more prevalent, especially for the identity community.
