# Automate Code Extraction from Modular Domains into Microservices

Use vFunction to modularize a domain and Code Copy to accelerate microservices creation by automating code extraction. Code Copy also generates Restful APIs for those services and automates needed framework upgrades.

“vFunction addressed a critical need for us to take thousands of our enterprise applications and modernize them through the use of an extremely powerful automated platform."

## Continuously Observe Your Applications

#### Iterative Modernization

#### Restful API Generation

#### Framework Upgrades

## Application Modernization Is a Process, Not a Project

Application modernization projects have been slow, cost prohibitive, and risky – for application owners and businesses alike. "Big bang" projects most often fail, exceed budget and timelines, and may never complete.

Lifting and shifting to the cloud is a great start but does not take advantage of the true value of cloud native architectures that offer much higher degrees of scalability, elasticity, agility, and engineering velocity.

#### Architectural observability enables

- Incremental modernization improvements  
- Technical debt remediation over time  
- Agile integration of architect-driven modernization stories  
- User-prioritized microservice extraction  
- Modernization progress in-line with business needs

## Accelerate the Transformation of Monoliths to Microservices

Extract code of modular domains from your complex applications into microservices to restore engineering velocity and increase application scalability.

#### Extract Microservices

Automate the extraction of the code required to compile your defined service. Eliminate dead code, automatically split classes, trim down configuration files, and deploy efficient, compact microservices.

#### Generate APIs

Create new RESTful APIs required for services and service boundaries. Generate new client libraries for shared common service use.

#### Upgrade Frameworks

Upgrade aging application frameworks including older releases of Java EE application server frameworks, e.g., WebSphere, WebLogic, JBoss, aging releases of Spring into Spring Boot, and more.

#### Iteratively Modernize

Continuously modernize and optimize your applications with vFunction [Architectural Observability Platform](/content/platform/index.html), then use Code Copy to extract microservices as business and release cycles allow.
