Azure Active Directory vs ORY Kratos: What are the differences?

Introduction

Azure Active Directory (Azure AD) and ORY Kratos are both powerful tools used for managing authentication and authorization processes. However, there are several key differences between the two. Let's explore them below.

1. Integration with Microsoft Ecosystem: Azure AD is tightly integrated with other Microsoft services such as Office 365, Azure, and Windows Server Active Directory. It provides seamless single sign-on (SSO) capabilities for Microsoft applications. On the other hand, ORY Kratos is a standalone open-source identity and user management solution that can be integrated with any system or service regardless of the technology stack used.

2. Flexibility and Customization: Azure AD offers a wide range of pre-built authentication and authorization features, making it easier to implement common scenarios. It provides a rich set of features such as user and group management, multi-factor authentication (MFA), and conditional access policies. ORY Kratos, on the other hand, allows for more flexibility and customization. It provides a set of APIs and tools that developers can use to tailor the authentication and authorization processes to their specific needs.

3. Cost Structure: Azure AD is a cloud-based service provided by Microsoft and has a subscription-based pricing model. The cost depends on the number of active users and the features required. ORY Kratos, being an open-source solution, is free to use. However, organizations may need to invest in the development and maintenance of the solution if they choose to use ORY Kratos.

4. Vendor Lock-in: Azure AD is a proprietary service provided by Microsoft. Once an organization chooses to use Azure AD, they are tied to the Microsoft ecosystem. Switching to another identity and access management solution may require significant effort and resources. ORY Kratos, being an open-source solution, provides more freedom and reduces vendor lock-in. Organizations can easily switch to alternative solutions if needed.

5. Deployment Options: Azure AD is a cloud-based service provided by Microsoft and can be deployed in various regions across the globe. It offers high availability and scalability. ORY Kratos can be self-hosted, allowing organizations to have complete control over the deployment and infrastructure. This can be advantageous for organizations with specific security or compliance requirements.

6. Support and Documentation: Azure AD is backed by Microsoft, a well-established technology company, and provides comprehensive support and documentation. Organizations can rely on Microsoft's support channels and resources for assistance. ORY Kratos, being an open-source solution, has a community-driven support model. Organizations can seek help from the community forums and documentation available.

In Summary, Azure AD is a tightly integrated, feature-rich, and cloud-based identity and access management service primarily designed for the Microsoft ecosystem. ORY Kratos, on the other hand, is a flexible and customizable open-source solution that can be integrated with any system, providing greater freedom and control over the authentication and authorization processes.
