Operate at webscale with mission-critical network control and security
Leverage webscale approaches in your enterprise environment. This Nokia use case describes how our cloud approach makes webscale not only viable but also feasible without requiring a forklift
Challenge: Webscale demands break legacy and open source-based architectures
Webscale requirements exceed the limits of legacy and most open source architectures in three major ways. Firstly, webscale apps require leading-edge functionality not found in legacy systems. Secondly, webscale architectures must achieve very high availability and performance running on general-purpose hardware. Thirdly, scalability needs are simply beyond the design parameters of most hardware and software.
Solution: Deliver webscale within your existing environment
Nokia makes webscale functionality viable for large enterprises. Within the data center, Nokia provides a scale-out and open approach. And, throughout the cloud environment, Nokia enables software defined everything (SDE) and a layered architecture.
Migrate your existing environment to a webscale architecture without forklift upgrades or scalability lapses
Enable faster capture and market response by removing limitations due to vendor lock-in and hardware incompatibilities
Provides cost efficiencies that scale
Get CapEx and OpEx cost efficiencies that scale with the environment through industry-standardized hardware
Provides a scale-out and open approach
By leveraging market-leading and thought-leading network products, including those of Nuage Networks (a subsidiary of Nokia), as well as a variety of Nokia IP, optical, and other hardware, Nokia provides a scale-out and open approach to cloud networking.
As shown in Figure 1, cloud management software, such as OpenStack, makes a provisioning request across the server, network, and storage (not shown). The Nuage Networks Virtualized Services Platform (VSP) provides the automation and security needed for the network to flex in synch with server and storage provisioning. Provisioning is consistent across multiple hypervisors, container hosts, and even bare metal servers.
By using declarative policies that are intelligently interpreted at the end point, operational requirements are decreased while increasing security overall. And, by storing each policy interpretation along with diagnostic information in a Big Data store, problem determination and compliance tracking do not break at scale.

Enables a “software defined everything” and layered architecture
As illustrated in Figure 2, the foundation for the webscale cloud is a robust and unified software defined networking and software defined WAN approach from Nuage Networks. With APIs based on developer-friendly standard REST, a wide variety of security and special-purpose appliances can be integrated into the application logic.
Cloud consumption interfaces enable public cloud resources to be leveraged, as well as leading development tools, such as Kubernetes and Mesos. The operations scalability interface provides communications with tools that provide mapping between physical and virtual resources along with other DevOps tools and approaches.
The flexible network interface ensures that the environment can overlay even the most sophisticated and complex network environment without requiring a forklift upgrade. At the top communication layer, the Nokia Rapport platform provides device support for a wide range of devices — from mobile through ATMs to distributed information kiosks.
