9. Migration to Modernization Strategy

Continuous
Modernization
BREADTH OF CHANGE
BENEFITS
TACTICAL (CONTAINERIZATION)
X No code modernization
X No technical debt removal
X No architectural changes
 Improves security
 Simplifies DevOps
X No scalability/elasticity
X No accelerated eng velocity
STRATEGIC (MICROSERVICES)
 Accelerated engineering velocity
 Shorter test & release cycles
 Increased scalability & elasticity
 Increased innovation
Setting Expectations 1: Migration vs. Modernization
MIGRATION MODERNIZATION
 Accelerated rate of change -
aging all applications faster
 Today's apps will be legacy
tomorrow
What are you trying to achieve?

10. UI
Business Logic
Database
Setting Expectations 2:
Avoiding Quick Fixes
❌ Backend business logic is still unchanged
❌ Code is still monolithic
❌ No change in scalability, engineering velocity,
or technical debt.
Still a
Monolith
Monolithic Architecture
Modernizing Everything But
the Business Logic
Modernizing the UI first is just putting a shiny
wrapper on a still persistent problem
UI tightly coupled with the business logic
Modernizing the Business Logic
First
Monolith
 Break down the monolith business logic and
create new micro frontends for each service
 Tackle technical debt head on
 Support rapid innovation & engineering velocity
<Decompose the
Business Logic
Monolith
Modernizing the busines logic will bring the
most value and competitive edge

Secrets to Successful Projects

Guidance for Success
1. Make the Case - first analyze the portfolio for architectural complexity, technical debt and to
identify aging frameworks; from here, prioritizations can be made, and then scoping the time, budget
and team members needed can be aligned.
2. Secure Budget & Resources - armed with the right business case, securing budget and
resources may be easier, especially when tied to the strategic business outcomes
3. Give It Consistent Report - support needed from executive management through changing
tides quarter to quarter is key to a successful project. Losing site of it in priorities and faltering on
commitment is a reason project stall, stop or end.
4. Define, Align & Train the Team - look across your team to determine what skills are in house
already, and what skills are need to add to the team. Next, gather the stakeholders and put the right
people in the right places. Finally, organize your team around the microservices - a critical element of
successful projects.
5. Provide Your Architects with Intelligent Tools - architects noted that not having the right
tools was as top reason for failure. Giving them intelligent tools will help reduce time and risk
