Mid-Size General Insurance Company
MuleSoft-powered PAS integration and zero-downtime ESB migration for a general insurer.
All case studiesA mid-size general insurance company processing 2 million policies annually across motor, health, property, and liability lines engaged Cydez Technologies to modernise its integration architecture and migrate from an end-of-life TIBCO ESB to MuleSoft Anypoint Platform. The insurer operated a core policy administration system (PAS) at the centre of 85 integrations connecting claims, reinsurance, agent portals, premium collection, regulatory reporting, and customer communication systems.
The TIBCO ESB had been in production for 11 years and was no longer supported by the vendor. Every new integration took 8-12 weeks to develop due to tightly coupled point-to-point connections and limited documentation of existing integrations. The insurer was planning a major PAS upgrade that required re-architecting the entire integration layer — but could not afford any downtime to live policy issuance, claims processing, or premium collection during the migration.
Cydez executed the migration using a strangler-fig pattern — migrating integrations one at a time from TIBCO to MuleSoft while both ESBs ran in parallel. All 85 integrations were re-architected using MuleSoft's API-led connectivity approach with Experience, Process, and System API layers. The new architecture reduced API development time from 8 weeks to 5 days and enabled the PAS upgrade to proceed 3 months ahead of schedule. The entire migration was completed with zero downtime to production systems.
- TIBCO to MuleSoft ESB migration (85 integrations)
- API-led connectivity architecture implementation
- Zero-downtime strangler-fig migration pattern
- PAS upgrade integration enablement
- API governance and developer portal
- Integration monitoring and SLA dashboards
A mid-size general insurance company running a legacy TIBCO ESB had 85 integrations connecting its policy administration system, claims engine, reinsurance platform, and agent portal. The ESB was end-of-life, expensive to maintain, and every new integration took 8-12 weeks to develop. A planned PAS upgrade required re-architecting the entire integration layer without disrupting live policy issuance and claims processing.
Cydez executed a phased ESB migration from TIBCO to MuleSoft Anypoint Platform using an API-led connectivity approach. All 85 integrations were re-built as reusable Experience, Process, and System APIs. The migration was completed with zero downtime through a strangler-fig pattern — migrating integrations one at a time while both ESBs ran in parallel. The new PAS integration reduced API development time from 8 weeks to 5 days.
How we delivered this project
Discovery
Cataloged all 85 TIBCO integrations over 8 weeks. Documented message flows, data transformations, error handling, and SLA requirements for each integration. Identified integration dependencies and sequenced the migration order to minimise risk. Assessed PAS upgrade integration requirements.
Design
Designed the MuleSoft API-led connectivity architecture with Experience, Process, and System API layers. Created the strangler-fig migration pattern ensuring zero-downtime cutover for each integration. Designed the API governance framework with lifecycle management, versioning, and security policies.
Development
Re-built integrations in 6 migration waves of 12-15 integrations each. Each wave followed: develop on MuleSoft, parallel-run with TIBCO, validate data accuracy, switch traffic, and decommission TIBCO flow. Built the Anypoint API developer portal and CloudHub 2.0 deployment pipelines.
Launch
Completed all 6 migration waves over 24 weeks with zero production downtime. Decommissioned TIBCO ESB after final wave. Trained 15 integration developers on MuleSoft. Enabled the PAS upgrade which was completed 3 months ahead of schedule using the new API layer.
What we built
API-Led Connectivity
All 85 integrations re-architected into reusable Experience, Process, and System APIs. Common services (policy lookup, customer validation, premium calculation) abstracted into shared APIs reused across 20+ consumers.
Zero-Downtime Migration
Strangler-fig pattern enabling one-at-a-time migration while both ESBs ran in parallel. Automated traffic routing and data comparison for validation. No impact to policy issuance, claims, or premium collection throughout 24-week migration.
API Developer Portal
Self-service Anypoint developer portal with API documentation, sandbox environments, and automated access provisioning. Internal teams and external partners can discover and consume APIs without integration team involvement.
CloudHub 2.0 Deployment
All APIs deployed on CloudHub 2.0 with auto-scaling, high availability, and DLQ-based error handling. CI/CD pipelines for automated testing and deployment. Environment promotion from sandbox to production.
Integration Monitoring
Real-time integration health monitoring with SLA dashboards. Automated alerting for latency spikes, error rate thresholds, and throughput anomalies. Monthly integration performance reports for IT governance.
Security & Governance
OAuth 2.0 authentication, rate limiting, IP whitelisting, and threat protection policies applied consistently across all APIs. API versioning with deprecation lifecycle management.
Measurable outcomes
- 85 integrations migrated with zero downtime
- New API development time reduced from 8 weeks to 5 days
- 60% reduction in annual integration maintenance costs
- PAS upgrade completed 3 months ahead of schedule
