A system may receive, from first computer systems, data sets via a first different data encapsulations; obtain the data sets from the first different data encapsulations; produce second different data encapsulations that include the data sets; and provide the second different data encapsulations that include the data sets to second computer systems that subscribed to receive the data sets. The data sets may be included in one or more data streams. The system may store at least two of the data sets. For example, at least two of the data sets may be stored until they are requested by one or more computer systems. One of the data sets may be duplicated and provided to multiple computer systems.
