Ollion’s FusionAuth Readiness Assessment & Enterprise EKS Implementation

Modern customer identity demands complete control over data, security, and cost. Ollion’s FusionAuth Implementation and Migration service helps enterprises deploy self-hosted FusionAuth on AWS EKS with production-grade security, scalability, and resilience.

As an AWS Premier Partner holding 11 Consulting Competencies and Audited MSP status, Ollion specializes in taking complex identity requirements—including zero-downtime migrations from Okta, Auth0, Cognito, and legacy LDAP—and converting them into automated, cloud-native deployments. Furthermore, Ollion enables next-generation Identity Governance for Agentic AI, leveraging FusionAuth Entity Management to enforce zero-trust policies for non-human AI agents.

Customer Challenges Solved:

• Escalating SaaS Identity Costs: Eliminate vendor lock-in and excessive per-user charges from legacy IdPs by moving to self-hosted FusionAuth on AWS.
• High-Risk Data Migrations: Avoid forcing password resets on millions of users during legacy IdP cutovers.
• Kubernetes SRE Complexity: Ensure EKS clusters, Aurora PostgreSQL databases, and ALB routing layers are properly tuned for spikes in authentication traffic.
• Ungoverned AI Agents: Lack of security, least-privilege scoping, and auditability for non-human AI agents accessing enterprise APIs.

Detailed Scope of Services:

• Operational Domain Evaluation: Discovery across Identity Schema, Token Architecture, Security/Tenant Topology, Infrastructure, and Compliance.
• AWS EKS Compute & Storage Architecture: Deployment of managed EKS clusters using Helm, external Aurora PostgreSQL, and ALB ingress controllers.
• Token & Schema Customization: Authorization modeling, custom JWT Populate Lambdas, and custom theme UI implementation.
• Migration Pipeline Engineering: Bulk import scripts, password transformer logic (salt/hash processing), and Connector Lambdas.
• Agentic AI Identity Setup: Modeling non-human AI entities with OAuth 2.0 client credentials, scoped token exchange, and immutable audit logging.

Deliverables:

• Production IAM Architecture & Token Specification Document
• Terraform & Helm Infrastructure as Code (IaC) Repositories
• Custom FusionAuth JS Lambdas & User Import/Migration Pipelines
• Automated Test Suites & Load Sizing Reports
• Post-Launch Hypercare Runbook & Handoff Documentation

Prerequisites:

• Access to AWS environment with rights to provision EKS, Aurora, ALB, and IAM resources.
• Relevant legacy IdP information, including password hashes if available or API access.
• Engineering allocation from client application teams for SDK/OIDC integration updates.

Assumptions & Exclusions:

• Assumptions: Client provides dedicated product owner and technical stakeholders for weekly governance.
• Exclusions: Refactoring client native application business code; third-party HRIS hardware provisioning.
