Centralize & Fix On/Off-Shore Mix



• Transform how we build products at CoreLogic• Embrace current trends (business & IT)

• Mobility, voice & social networks• Platform as a Service (Pivotal Cloud Foundry)• Big Data tools (Hadoop, etc)

• Stand-up CoreLogic Innovation Labs• Work with Pivotal to leverage modern agile development paradigms such as

Minimum Viable Product (MVP), Paired programming, Test driven development (TDD), and blue/green deployments

• Invest in the CoreLogic Platform (CLP)• Build re-usable services & components• Consistent technology stack

CoreLogic Imperative: IT Transformation



• B2B Integration of Customers & Fulfillment Providers (CoreLogic & 3rd

Party)• Integrate applications and systems to derive business value• Facilitate migrating customers to new applications

• Order Management• Centralized view of orders, metrics, reporting – for customers and internal

support• Eliminate redundant and duplicate order management gateways• Build controls through governance• Enable enhanced order services such as Decisioning, Bundling• Reduced operational cost

• API Management• Manage externally exposed APIs• Implement QoS and security policies

B2B XML

EMS



• Utilize API-X on the boundary• Provide API security (either API-keys or Mutual SSL)• Perform limited XSLT’s – such as wrap/unwrap SOAP, modify headers,

extract required payload elements• Use to perform outbound POST-backs to dynamic URLs

• Utilize BW 6 for Order Management functions • Validate XML, validate field values, determine what provider(s) to route

orders to, perform XSLT’s (e.g., MISMO 2.x -> MISMO 3.x)• Application .ear implemented via SEDA architecture using EMS queues

to exchange messages between components• Two primary flows: Request & Response

• MongoDB used as primary message store

Solution Approach



Global Gateway – new order Request Flow in BW6



Project Results and Benefits

Goal Result

Improve speed to market and ability to onboard new products more quickly

By leveraging BW6 and the rich graphical editor, it was quicker to get the overall logic in place quicker than writing custom code, reducing the time to launch Property Tax Estimator (PTE) product to market

Make it simple and more cost-effective to do business with CoreLogic

Solution allows additional Customers & Fulfillment providers to be on-boarded easily via configuration instead of code modifications

Provide a unified approach for access to all CoreLogic products and services

A single URL to integrate with + consistent integration guides reduce the pain and friction of ordering additional products; integrate ONCE and get all of CoreLogic



• Some Challenges w/ Business Works 6• Struggled working in a team environment where multiple developers

are working on the same .ear (conflicts)• Does not work well with SCM’s such as git (diff’s are mostly useless

meta-data) hence not possible to do traditional code merges• Challenging to employ Test Driven Development (TDD) as container

start-up is expensive; also haven’t figured out how to unit test components in isolation

• Infrastructure challenging to set-up/configure/automate; thus far unable to achieve an immutable server strategy

• XML parsing/validation originally done outside of BW6 due to performance issues (MISMO .xsd is quite large)

• Standard practices such as CI (Jenkins) are non-trivial

Product Pain Points



• Business Works 6• Productive Integration Platform – but requires significant

investment in people, processes & technology

• Solve for the infrastructure pain points• Investigate Business Works Container Edition

• Need to cloudify our BW6 .ear applications (12 factor apps)• Want to be able to scale BW applications just like we do our PCF apps

• Still a gap for API-Exchange

• Explore ways to improve testing• Desire to be more consistent with our Java Spring Boot apps

Recommendations & Next Steps
