On witnessing this technological gap, a Ph.D. student, Murad Kablan and his advisor, Eric Keller set out to redesign network functions to overcome this challenge. At the core of their network architecture, the state of network functions was decoupled from their underlying processing to achieve high scalability and resiliency. While decoupling state is not a new concept, it historically has been challenging to realize in large scale networks with high-performance demands.
The technology built by Murad and Eric resolves all the intricacies associated with network architecture.
After developing the technology at the University of Colorado Boulder, the two went on to commercialize what they had built and founded Stateless. They grew the team and developed a groundbreaking network service platform that streamlines the deployment and management of network functions in multitenant environments. In addition to breaking the tight coupling of state and processing in network functions, the platform uses principles from micro-services to break down monolithic network appliances into smaller components.
The platform runs on any commodity hardware—the initial deployment requires two OpenFlow enabled switches and fourx86 servers in a scale-out clustered architecture.
Our ultimate mission is to create the most sophisticated and dynamic networks that are also dead simple to manage
Subsequently, more servers can be easily plugged in or removed as per the network capacity. “Our solution leverages the concept of scale-out architectures. This is very essential for CIOs who are forced to forecast the growth of their network bandwidth in the next 5-10 years,” states Kablan, CEO of Stateless.
The platform provides resource management, orchestration, and a user interface, while the library of network functions provides value-add services that can be chained together to fit an enterprise’s exact business requirements. The managed hosting provider just needs to build isolated chains of network services, configurable through API calls or a web interface, and the services are ready in a matter of minutes. Stateless’ web user interface also allows hosting providers to control the cluster and monitor tenant traffic across the network seamlessly.
“Our ultimate mission is to create the most sophisticated and dynamic networks that are also dead simple to manage,” states Kablan.
Stateless is laying the groundwork to grow beyond the managed hosting provider market segment. “We see large enterprises having many of the same challenges with their networks,” said Kablan. In another exciting development, Stateless is also working to integrate the platform with a hyper-converged infrastructure (HCI) package of a leading company.
