First, the cloud-native transformation represented by Guidewire Cloud is in full swing, targeting 80% migration by 2030, with global top-tier P&C carriers lining up to migrate. Second, Korean and Japanese insurance cores that have survived 30 years on COBOL/AS-400 mainframes now face a modernization cliff. Guidewire InsuranceSuite (PolicyCenter/ClaimCenter/BillingCenter), Duck Creek OnDemand, Sapiens IDIT and CoreSuite, Insurity, EIS Suite, Majesco, FINEOS Claims, Origami Risk, Britecore. Korea Samsung SDS insurance IT, KB CIS, Hyundai Marine in-house, Japan NTT Data, NRI ZAITAS 30-year trajectory. Structural differences between P&C and Life & Annuity cores, API-first architecture, the meaning of low-code/no-code, microservice decomposition patterns — all covered.
