design

Requests are handled by flask, a bunch of urls are inserted in the object store (redis) and arguments are put on the queue (redis again) for workers to consume. More workers would mean more items processed in parallel.

Other possible implementations:

• multiprocessing module for consuming all cpus.
• multiprocessing.managers.SyncManager for distributing task to other machines.

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
