OKTA Implementation Design for Healthcare Company with GovCloud Integration
CIAM and Okta Overview
Customer Identity and Access Management (CIAM) is a specialized identity management framework focused on enabling secure, seamless customer access to digital services. Unlike traditional IAM that serves employees, CIAM manages external user identities at scale while prioritizing user experience, privacy, and security.
Okta is a leading cloud-based CIAM platform that provides secure identity management through:

Single Sign-On across multiple applications
Adaptive Multi-Factor Authentication
Universal Directory for centralized identity management
Lifecycle Management automation
API Access Management with OAuth 2.0/OIDC
B2B integration capabilities
Comprehensive security features and compliance certifications

Company Analysis and Requirements
The healthcare company serves millions of clients across both private and government sectors, focusing on medical exam scheduling and records management. Key requirements include:

Minimal disruption to existing clients during implementation
Seamless onboarding for 100+ application development teams
Cost-effective licensing model
Integration with existing DMZ Active Directory
Support for 2 million client identities
Healthcare-specific compliance requirements (HIPAA)
System and application resources hosted in AWS GovCloud
