We know Google has enormous data centres. A new blog post from the search giant reveals a key strategy in how it manages networking within those centres: by ignoring standards.
Consistent with the "build your own" philosophy it takes with hardware, Google tends to rely on its own solutions to manage networking:
We build our own software and hardware using silicon from vendors, relying less on standard Internet protocols and more on custom protocols tailored to the data centre. Taken together, our network control stack has more in common with Google's distributed computing architectures than traditional router-centric Internet protocols.
Of course, that's easier to do when you have Google's deep reserves of cash -- for most businesses, sticking with standards is a safer approach. Nonetheless, the whole post is interesting and worth a read.
