In the past, connectivity was simple. Large enterprises hosted the majority of data and applications on-site or at a nearby data centre, and satellite offices connected back to HQ using basic technologies. Since everything important was hosted nearby, traffic from satellite offices could be routed through HQ for security purposes. This slowed down user access to the corporate network, but that was a minor concern.

However, things have changed. Practically every organisation has adopted some form of cloud services and storage to some degree, while many have embraced hybrid cloud strategies. On top of that, most organisations employ at least a handful of Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS) solutions offered by cloud service providers (CSP). Now, a huge percentage of network traffic must be routed out to third party network service providers for these cloud services.
