7. HOW

8. RETAIN
ROI not high enough (for now)
RETIRE
decommission non used legacy
applications
REPURCHASE
buy a SaaS solution
REFACTOR
optimize your solution architecture in
order to take advantage of cloud native
features
REPLATFORM
benefit from cloud infrastructure
REHOST
move the application to the cloud
without making changes to the
underlying code base

9. Application modernization

features
Solution architecture

17. Monolith
Software whose design,
information model, and interface
combine multiple competing and
interfering domains into one single
application and data model

18. When monoliths
grow…
• Delivering new features takes a
while
• Not testable
• Technical debt
• “legacy”
• No business nor developer
happiness

19. Microservices
A microservice is a service with a
design focus towards the smallest
autonomous boundary

23. Towards cloud native
A cloud native application is
an application that has been
designed and implemented to
run on a PaaS installation and
to embrace horizontal elastic
scaling

24. Towards cloud native
• Microservices
• Serverless
• Function as a Service
(FaaS)

25. Microservices are great, but you need to
GET there, not START there
