Cumulus Networks ® Case Study NephoScale + Cumulus ® Linux ® NephoScale Builds Scalable, Affordable Cloud Network with Cumulus Linux INDUSTRY: Cloud + Hosting BUSINESS OBJECTIVE: Automated, Scalable Solution PARTNERS: Edge-Core, Opscode, Chef, Inmon "With Cumulus Linux, manual configuration is no longer needed for provisioning new racks, applying new policy or responding to security advisories. The lifecycle is now entirely automated. " — Alan Meadows, Chief Architect at NephoScale Overview NephoScale is a cloud Infrastructure-as-a-Service (IaaS) provider and cloud software development company. Their NephOS end-to-end cloud software stack powers the IaaS platform and was developed from the ground up to accelerate and simplify provisioning, deploying, and installing highly scalable cloud infrastructure. NephOS enables a hybrid cloud solution that seamlessly ties a customer's on-premise cloud environment with their hosted off-premise cloud environment, visible in a single-pane view. Since infrastructure is such a critical part of the business, NephoScale needs to rely on fast, scalable, and flexible designs to meet customer needs as the business grows. Challenges When NephoScale faced capacity limitations and recognized the need to upgrade their 1G environment to 10G, the team investigated options that would allow high capacity at scale, automation, and programmability. These criteria reflected their need to respond quickly to customer demands. The criteria for choosing a solution included: Standardize on the OS that allows freedom The NephoScale IT team was very familiar with Linux as their data center infrastructure was running on it. NephoScale wanted to leverage existing tools like Chef and Linux skill-set for their network. They wanted to have the same operational framework on their switches and on their servers. Eliminate Layer 2 complexities as much as possible One of the core beliefs at NephoScale was that their infrastructure should be built for scale, and a solution should be able to take them from one rack to hundreds of racks. The architecture and the solution should support VXLAN tunneling and eliminate Layer 2 complexities. Solution After comparing multiple architecture and solutions from various vendors including Cisco, Arista, Dell/Force10, and Open Networking switches running Cumulus Linux, Nephoscale deployed Clos Layer 3 architecture and settled on Cumulus Linux to provide flexible solutions that can scale affordably. The solution enabled Nephoscale to deploy high capacity that was easy to manage. ©2016 Cumulus Networks. All rights reserved. | cumulusnetworks.com
