IAM can be implemented on-premises or in the cloud. Cloud-based IAM solutions offer advantages such as lower maintenance costs, accessibility for small businesses, access to expert support, dedicated security and compliance features, and scalability. Cloud IAM allows organizations to offload infrastructure costs and benefit from managed services. Hybrid IAM solutions provide flexibility, allowing organizations to retain control over their identity stores while leveraging cloud-based services. Cloud IAM also enables the implementation of advanced features like biometrics and multi-factor authentication without the need for extensive hardware and internal IT infrastructure.
