Summary
In this chapter, we dipped our toes into the networking and distributed capabilities of Julia. I didn’t discuss its threading capabilities since this is purely experimental, but much effort is being directed to it and it should be a major feature in Julia v2.
We started with basic networking services available from UDP and TCP sockets and showed how a simple “Julia through the looking glass” echo sever could be written. Then, we moved on to web clients and servers prescribed by the HTTP.jl
package. After, we discussed how, when working on the web, it is possible to implement socket-style systems using HTTP protocols.
The last section was somewhat different, in which we considered Julia’s approach to executing tasks in parallel over distributed and multiprocessor systems and dealing with datasets distributed over multiple data files. There is one separate topic that must be considered and that is using Julia in the cloud; we will cover this...
