requires our integrations to modernize too.
It’s now possible to run microintegrations in

Example: Major Car Rental Company
• Problem Statement:
• Digital Channel initiative successfully implemented with mobile and web apps
• Agile programming using microservices and APIs
• The agility runs into a bottleneck when the native apps are dependent on the APIs into the SORs
which are running on traditional integration products with central governance and waterfall
development methods.
• Objectives for modern integration
• Refactor backend API logic into more granular functions and into microservices based integration
flows, perhaps to be run within the scope of the digital app.
• Apply IBM Garage method to the integration development team and look into decentralizing the
integration capability ownership.

Example: Global Building Materials
Manufacturer
• Problem Statement:
• Native applications (web and mobile) are accessing enterprise information through a API
Management SaaS platform and a DBaaS.
• Data is replicated from the SORs to the DBaaS component based on integration flows running in an
ESB which encountered timing and sequencing constraints.
• API logic is implemented in the SOR database itself via complex SQL stored procedures which ran
into scalability and performance issues, not to mention the flexibility of changing stored procedure
logic.
• Objectives for modern integration
• Use event streaming pub sub to replicate data events in the SOR in near real time into the DBaaS
component
• Refactor the stored procs logic into micro integration flows that run on lightweight integration
runtimes to be invoked at the granular level by the native apps

What patterns do we see?
25
This is where “integration modernization” sits

25.
IBM Garage
27
What might an “Integration” Modernization
Project look like?
• Use Design Thinking to define the scope of the project from a user perspective to ensure there is user
value from the project.
• Run an architectural workshop to define the technical approach to modernization.
• Do some other application modernization work.
• Set up a container platform if required (e.g. IBM Cloud Pak on OpenShift).
• Migrate/Refactor an existing integration pattern from the Data Center into the Platform (e.g. APIC)
• Create a lightweight integration microservice to embed in the native app (e.g. a stateless flow)
• Define DevOps flow for refactored integration components.
• etc…
• Release!

IBM Garage
Summary
28
• Application Modernization requires
Integration Modernization, and vice-
versa. They do not exist in isolation.
• Integration should now be thought of
as just another implementation
technology (programming language?)
for microservices / containers.
• It’s a long journey. The IBM Garage
can help define the right MVP to get
you started and co-create with you to
help you learn.
