How we modernize legacy systems

Using different technologies, we convert large monolithic systems into smaller independent microservice modules built on uniform principles and platforms. Each module handles a specific business agenda or operational area.

Microservice modules can exist independently or work together. This approach has proven successful for us in upgrading our own solutions. Incremental modularization makes it easier to replace legacy systems without the high risks associated with replacing entire systems at once. We use the ARBES DIGITAL PLATFORM tool we developed to modernize legacy systems.

ARBES DIGITAL PLATFORM, ADP for short, is a universal orchestration and integration platform containing microservice modules that support specific business agendas and platforms. It is based on shared principles for software design and implementation, using a set of unified tools and opensource technologies to do so. It is easily deployable in any environment or cloud.

  • Natively, it also supports multitenancy, i.e. serving multiple entities from one enterprise group at the same time.
  • Above all, it serves specific business agendas using its easy-to-deploy modules.
How can ADP help your IT?
  • It integrates any existing legacy systems with frontends, orchestrates business processes across various systems and provides its own monitoring, logging, auditing and security.
  • It provides backend functionalities that may be lacking for a specific area – microservice modules lighten the load on existing legacy applications.
  • Creates an opportunity to get rid of dependence on vendors for these systems.
  • It allows for more flexible deployment of new technologies, both in the client environment and in any cloud environment.

General Architectural ADP Model

General Architectural ADP Model Technologically speaking, ADP is a set of key principles and approaches to software design and implementation. It creates a highly coherent roadmap for the design, development, implementation and operation of a modern application/information system.

The ADP Framework is a collection of libraries, tools and processes. The Framework contains an ever- growing repository of fully compatible, reusable components combined with highly efficient tools, all relevant guidelines and a development process, giving you the ability to quickly build and run applications without compromising quality and long-term maintainability.

The ADP microservice module represents a set of functionalities related to a specific business domain/agenda, e.g. sales commissions.

The following diagram provides a general architectural model of ADP.
