Migration Scenario: Migrating Backend Processing Pipeline to the AWS Cloud

Figure 1: Company C Architecture (Before Migration)

Use case

Company C is an automobile insurance claim processing company with an external-facing website from which claims are received and processed.

This pipeline consists of application servers that ingest the claims into a normalized relational database. Claims are then validated using the Rules Engine. The Rules Engine verifies and validates the data in the claims with the help from internal and external services like the 3rd party

Address Verification Service. Both the application server and Rules Engines are built using standard .NET technology. All the validated data is again stored in the same database which is backed up to tape drives periodically. Disputed claims undergo a complex workflow process and are processed using legacy systems. Undisputed claims are directly fed to the payments and billing system. The entire claims processing workflow is audited and logged in Reports DB running on MySQL DB, and central Claims DB using a SQL Server database.
