This chapter is a follow up on some of the topics that we discussed so far. In particular, it explores asynchronous programming and distributed computing in detail with some example applications. It concentrates on Celery, a sophisticated Python framework that is used to build distributed applications. Toward the end, the chapter explores some alternative packages to Celery: Pyro and Python-RQ.
You should be familiar, at this point, with the basic ideas behind parallelism, distributed computing, and asynchronous programming. If not, it might be worthwhile to skim the previous chapters to get a refresher.
