Around 10 percent of enterprise-generated data is created and processed outside a traditional centralized data center or cloud, according to Gartner. By 2025, Gartner predicts this figure will reach 75 percent, says Santhosh Rao, Gartner senior research director.
As the volume and velocity of data increases, so too does the inefficiency of streaming all this information to a cloud or data center for processing.”
That is the reason many are convinced edge computing will be important: possibly 75 percent of computing shifts to venues outside private data centers and hyperscale data centers, eventually.
Some processing will continue to be done by devices. Other processing will happen locally, inside a building, at what some call a gateway. “Edge servers can form clusters or micro data centers where more computing power is needed locally,” says Rao.
“Servers deployed in 5G cellular base stations will host applications and cache content for local subscribers, without having to send traffic through a congested backbone network,” says Rao.
And there are signs enterprises believe edge computing has its place. About 37 percent of 100 service provider executives surveyed by 451 Research on behalf of Vertiv already have deployed at least some edge computing to complement their mobile operations, Vertiv says. An additional 47 percent say they plan to deploy their own infrastructure edge assets.
Though most of the infrastructure edge use cases (including multiservice edge computing) involve the need for ultra-low latency performance, there are some use cases where bandwidth also is fundamental.
Virtual reality video quality similar to high-definition TV quality requires bandwidth of 80 Mbps to 100 Mbps, compared to 5 Mbps for HD video streaming, for example.
