#The xtractor code#
The application goes through a refactoring process to fix any issues that may prevent the code form being extracted.This will include the candidate code, as well as additional classes that are required for the candidate code to function. Within selected application a group of classes is identified as the boundary of the microservice.

A subset of the application’s code is identified, by one of the above methods, as a good candidate for refactoring and extracting to make a new microservice.The exact steps in the refactoring process will vary from team to team, but generally operates similarly to the following process model: In this case the Microservice Extractor will remove the business logic from the controller and reroute all of the public calls to the new microservice. A second option is to use a particular controller in your application as the top-level construct. One option for code selection is to identify a particular class that contains all of the business logic necessary for extraction and base the refactoring effort using this class as a boundary.
#The xtractor update#
With this approach, once an area of code has been identified for some other update work, it will be refactored and modernized as part of the process.
#The xtractor upgrade#
This approach selects functionality for refactoring as the specific area needs some form of other upgrade or bug fix.

Another approach is to refactor parts of the application as the need arises for updates or upgrades. For example, a set of logging code that is called from many different places, but doesn’t rely on other code.

Some customers will opt for a “Low Hanging Fruit” approach, where the selection of functionality is determined by how easy it will be to remove candidate code form the solution. How a customer selects the target code, or domain to be refactored, will typically follow their development methodology. Eventually all that will remain as the monolith will be the presentation layer, with all business logic migrated into microservices. In this case, the customer usually has little interest in preserving existing code.įor customers who are not opting to perform a complete rearchitect and rewrite of their applications, the development teams will often employ the strangle pattern, where pieces of the application are selected and refactored out of the monolith, leaving progressively less and less of the application behind in the monolith. This approach may also be taken for larger applications when the customer is performing a major upgrade, and can allocate the time and resources required to start over. This approach is most common with smaller applications where the effort of rewriting the application is more effective then breaking up the application in to component pieces. Some customers will approach breaking up the monolith by allocating time to completely rearchitect and recreate the application. NET, a new tool that helps customers on their path to extract microservices from their monolithic applications customers can leverage this tool to more easily achieve their modernization goals with a tool that assists in the extraction of microservices. Today we are announcing the AWS Microservice Extractor for. Customers seeking to modernize applications have a variety of goals that include making their applications more stable, and moving to newer technologies such as serverless and microservices. These applications could be internet facing products, which were developed as monolithic applications, or applications designed to help with internal processes. These days customers are increasingly looking to modernize internally developed applications.
