A system for executing services in a distributed way, the execution of each service involving the processing of a plurality of tasks of predetermined types, each task type to be processed being represented by a corresponding type of tuples of data relating to the task type, wherein: the system comprises a plurality of peer entities; each peer entity is adapted to store and execute a plurality of worker modules, each worker module being adapted to process at least one task type; each peer entity comprises tuple handling modules that, for a tuple of a type T, are adapted: a) to check if at least one of the plurality of the worker modules comprised in the peer entity is adapted to process the task represented by said tuple, b) in the positive case of a), to take in charge the processing of the task represented by said tuple, c) in the negative case of a), to execute a forwarding procedure for forwarding said tuple to another peer entity of the plurality of peer entities of the system.
