The ACRON Service enables users to create crontab entries for Kerberos-authenticated cron jobs.

These (a)crontab entries are added to a table on one or several central cron servers. The registered command is then executed on a user-specified target machine, equipped with fresh Kerberos credentials of standard lifetime.

ACRON should be used in place of cron when the job you are running needs to write to AFS, ssh or scp against a target node, or perform other tasks that require a Kerberos ticket to execute. If you do not need a Kerberos ticket to run your job, a local cron job is sufficient and much more straightforward.

The GRID Data Transfer Service used at CERN is called File Transfer Service (FTS); it is a data movement service.
FTS aims to reliably copy one Storage URL to another. It uses a 3rd party copy (e.g. gsiftp) to achieve this, but will retry if this fails.
It also schedules these copys along network channels to ensure that bandwidth is properly used.
State in the FTS is held in a database, which ensures that the service can be restarted reliably.
FTS is used by the experiment frameworks (typically the end-users do not interact directly with it).
Experiment frameworks submit jobs to the FTS; a job is a set of pairs with source and destination file names.

A message broker is an intermediary program that translates the language of a system from one internationally recognized language to another by way of a telecommunications medium. It is an architectural pattern for message validation, message transformation and message routing. It mediates communication amongst applications, minimizing the mutual awareness that applications should have of each other in order to be able to exchange messages, effectively implementing decoupling. This mediation is provided on best-effort basis with no guarantee that the messages will always reach the consumers.
