Amazon Cognito vs. Univention Corporate Server (UCS)

Well Suited

1. B2C mobile and web apps with a high number of users.
2. Cheaper and cost-effective.
3. If the other pieces of the infra are already using AWS services like Lambda, S3, Pinpoint, etc.

Not Suited For:

1. Advanced use-cases (Biometrics based authentication) Email, and other MFA channels.
2. For any use-cases needing SCIM.
3. Customized flows of SSO, and MFA will need a layer on Lambda and other AWS services.

Incentivized

Univention Corporate Server is well suited:

1. If an Organization would like to use it as a complete Active Directory Server.
2. If an Organization wants to deploy other applications which are important like SSO, Mail Server, 2FA etc., as with one click all these Apps will be integrated magically thus reducing the Admin job considerably.
3. Web based management which will be quite useful for the Admins who are from Windows background only.
4. Univention as a company which has close to 2 decades of experience.

• Strong integration with React.js and client-side applications
• Easy to bridge Cognito identities with the rest of the AWS ecosystem
• Easy to store user profile data directly in Cognito rather than having to build additional services/endpoints
• Easy integration with AWS Lambda to extend and add sophistication to the service

Incentivized

• Complete replacement for MS Active Directory Server.
• Univention App Center - awesome concept with which Apps can be installed for the Domain.
• App Center can be compared to Google Play Store or Apple Play Store - Organizations can gain tremendous advantages.
• Plethora of Apps which are both free and paid and excellent apps for the Organizations.

• Amazon Cognito has a bit of a learning curve. You need to learn its concepts and terminology. The documentation does not describe some topics comprehensively.
• Some Console screens would benefit from improved search and filtering options.
• When another AWS product (e.g., SageMaker) configures Cognito on your behalf, it is not clear what you're getting. For example, the expiration of a temporary password was configured but never communicated.

• As Univention is from Germany, lot of informative articles are in German but English articles are also good but less in number.

Amazon Cognito is easy to use and implement if you don't need to implement custom policies. But if your security team requires something outside the box, then implementation becomes complicated and you risk wasting time. There is no option for customizable regex for passwords, which is a major deficiency. The standard password policy, allow to choose the length of the password, if it should contains at least one number, one special character, one uppercase letter and one lowercase letter.

Community support is excellent, many times even better and quicker then the offical AWS support. I really cannot recommend community support enough! Apart from that the service is relativily easy to use and does not have a huge learning curve. Examples are easy to follow and will help you start using the service.
