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.

• SCIM implementation is not present.
• B2B SaaS use-cases are very hard to configure. More suitable or B2C use-cases.
• Needs more recipes, plugins, SDK's.
• 2FA with Email as an OTP channel is not supported.
• 2 FA using biometrics is not available; can be customised using lambda.

Incentivized

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

All the features AWS Cognito offers gives the user the options they need without making it too complicated. Your customers will be happy. On the administration site usability is also great. After a small learning curve, you can setup Cognito for your usage

AWS Support overall is poor. Your main resources are trainings and the docs, and the docs can be very confusing. Using Cognito well involves having a developer learn it deeply and help support your team in understanding it. That said, Cognito's competitors also have dismal support and even worse documentation, so while this isn't a strength for Cognito it may still be the frontrunner here.

We have evaluated Zentyal and ClearOS but we found out that UCS is more suited to every Organization.

• Amazon Cognito has had a positive impact on our business by allowing us to develop services that require user sign-up and sign-in more rapidly. Not only do we not need to build or maintain these features, but Cognito's implementation is also better than what we would be justified in building ourselves.
• Amazon Cognito makes user management easy. This reduces the time we have to spend supporting users. Non-technical product managers can even use the AWS Console to manage users without requiring support from developers.
• Amazon Cognito is likely more secure than what would be built in-house; a portion of our attack surface is now managed by Amazon.

Incentivized

• As a partner, we have gained lot of respect from our customers as UCS is rock solid.
• UCS is truly Open Source.
• UCS has surpassed our expectations.
