The hottest social media discussion earlier this year centered around the colors of a dress, and whether you see it as blue or white with black stripes. But let there be no illusions regarding the color associated with Nokia’s Operations Support Systems (OSS) in the Cloud. It’s green. At least that’s how we see it. Here’s why…
Virtualized OSS requires less energy
Virtualized OSS software applications don’t require their own dedicated hardware for each product, but can be combined on the same server. Fewer hardware elements are thus needed, even up to 30% less in a multi-product environment. Less hardware requires less space, which also means that data centers can be smaller. And we all know that every square meter has a price tag. The color of the resulting decrease in energy consumption and cost metrics is definitely green.
One part of the virtualized OSS is the iSON Manager, a tool for network operations and maintenance to automate operations in several ways. One way is to decrease the amount of energy used by networks. In a pilot project, Nokia iSON Manager helped Korea Telecom save 40% on its consumption by shutting down particular frequencies when they weren’t needed. Such a cut in energy usage, which is managed by a cloud service, is certainly very green.
Ecological cooling and utilization of waste heat
The construction of multi-functional data centers can also be planned with a green philiosophy. Data center servers accumulate heat and require cooling. One example of what we’re doing at Nokia’s Finland premises involves the water we use for the cooling process: we recapture any unused heated water and redirect it to nearby hospitals, schools and other heating facilities. So green OSS supports not only our data center but also the community at large. This interconnected district cooling and heating system was introduced at Nokia in Tampere, Finland, but if this were to be globally deployed to data centers around the world, energy savings would be equal to power produced by a hundred nuclear power plants!
The virtualization of OSS requires that processes, use cases and competencies are evaluated and re-defined. The more software involved, the more we can make the network a programmable world where automation serves both network operators and their customers. Combine the benefits of data centers with the evolution towards automation, and you’ll see the green OSS cloud in the sky!
