Upgrade .NET Framework
Upgrade legacy .NET Frameworks to .NET 4.8.
Windows OS is kept as it is.
E.g.
2.0 → 4.8
3.5 → 4.8
4.5 → 4.8
Move the codebase to .NET core
Usually the OS is also upgraded to Linux containers.
DevOps practices are improved. Avoid paying ~50% of
instance running cost as Windows licensing fees.
Change the data store
Mix of Dynamo DB, RedShift, ElastiCache & Aurora
SaaSification
Change the business model
Modernization path we typically see
Sooner or later customer has
to do these steps

Porting Assistant for .NET

Assisted porting
Assessment report
Scan
Porting Assistant
for .NET
Scans .NET Framework
applications to find APIs and
NuGet Packages that are
incompatible with .NET Core
Generates compatibility
assessment and suggests
available replacements
Updates packages and
changes project reference
files for you to start porting
Insight and assistance
for porting from .NET
Framework to .NET Core

Monolithic vs
Microservices Architecture

Monolithic application Refactored microservices
Limits experimentation: Independent teams: can build, test, and release
new functionality independently
Impacts scalability: a spike in demand may
require architectural changes to the entire app
Impacts availability:
Granular scaling: without replicating the entire
application
Localized failures: don’t risk uptime for the
whole application

Challenges when moving to microservices
Need to use multiple tools to co-relate source code and runtime metrics

AWS Microservice
Extractor for .NET

Demo

We are going to extract Inventory as a microservice
These classes depend on Inventory
Inventory needs these three classes
