By implementing the Local Integration Gateway (LIG) for one of the world’s largest telecommunication groups, ConSol created a comprehensive interface solution. LIG controls the external access – e.g. of shops, branches or contracting partners – to internal systems and applications. The solution is based on up-to-date microservices, processing queries efficiently and error-free. ConSol experts linked more than 80 systems to the LIG. Meanwhile, the system as a whole is processing about 2.5 million transactions a day.
