Abstract: A system and method for identifying and removing dead-code from a computer program of an independent service is provided. The method includes: retrieving information related to the code of the service, wherein the retrieved information includes at least static and dynamic dependencies information of classes of the service; constructing a static dependencies graph, wherein nodes of the static dependencies graph are classes, and directed edges depict static dependencies between classes; classifying classes based on the static dependencies; constructing a first subgraph to include classes classified as internal-pure-static (IPS) classes; detecting external-dead-class candidates by traversing the subgraph; adding external-dead-class candidates to a dead code cut (DCC) set; and removing at least one class included in the DCC set from the code of the service.

Abstract: Systems and methods method for mapping between function calls and entities of the computer program. The method includes executing a computer program in a first computing environment; determining a first entity of the computer program to track; assigning an identifier to the first entity; determining the first entity has been accessed by at least one function call; and mapping the at least one function call with the identifier of the first entity; generating a cluster including the at least one function, wherein the cluster may be executed independently from the rest of the computer program.

Abstract: A method and system for identifying and extracting independent services from a computer program are configured. The method comprises retrieving code and runtime data of the computer program, upon reception of a request to extract at least one service; performing a dynamic analysis on the retrieved code to determine code resources of the computer program; identifying, based on the code resources and runtime data, boundaries of services included in the computer program and are independent of other services; and deriving context and compile-time dependencies of the computer program using static analysis; and generating based on the context, compile-time dependencies, and code resources a service specification file for each independent service of the services included in the computer program, wherein an independent service includes all resources require for its execution independently of the computer program.
