The internet is the great granddaddy of data sharing –

but that doesn’t mean it’s always the right choice for your primary data.

It’s a lot like public transportation:

Trains can be unreliable, delayed and overcrowded.

If you need to arrive somewhere on time and in one piece, you might take a private route –

in a taxi, an Uber or your own car.

but it might arrive late, covered in a stranger’s coffee.

The same thinking applies to the internet.

Public IP transit gets data to its destination…

Up to 50 percent of cloud customers bring at least some workloads back

on premises due to latency

and other performance issues with production applications (according to IDC).

any application using storage across the public internet gets saddled with

up to 100ms or more of latency.

Even when users have sufficient bandwidth,

It’s time for enterprise storage to follow suit. Your customers depend on you

for instant data access –

you can’t afford to share bandwidth with the entire internet.

Private, dedicated networks get customers off the subway and into a cab.

Users can access masses of data when they want it, where they need it,

and predictably experience full throughput at multi-gigabit speeds.

Page 17: The commuter's guide to connectivity and latency

That means average read latency well under 10ms and average write latency

under 20 to 25ms.

(In other words, the days of sharing internet bandwidth with Netflix downloads

and mobile chat clients are over.)

Public IP transit will get data to its destination,

but even its best efforts won’t cut it for today’s primary data requirements.
