At such a high level, nothing should be different. If one looks
closer, one will notice that performance is different and possibly not
everything is compiled / available, but that's easy to notice simply
some packages missing dependencies or not available. In practice all
usual things are available.

You may launch ARM (emulated) instances on Amazon EC2 cloud. Or
locally use qemu-user-static: e.g. $ mk-sbuild --arch armhf trusty ; $
mk-sbuild --arch arm64 trusty (should work on saucy & trusty host
operating systems), which then gives you working chroots, e.g. $ sudo
schroot -u root -c trusty-arm64

Typically development happens on normal amd64/i386 machines. If there
native code involved, one can either cross-compile or perform native
compilation, then test in emulators / test-systems and deploy. For
armhf, there are fairly cheap development boards one can use - e.g.
panda board. arm64 stock is very limited and exclusive at this point
in time.
