As the speed of change increases, organizations are moving to the cloud for its promise of limitless scale, flexibility and agility. But the wide adoption of cloud—as well as mobile, M2M and big data applications—is having profound impacts on IT infrastructures.
The traditional way of implementing networks and services in hardware makes them static, rigid, manual, and unable to respond as application requirements rapidly change.
To pull off this transition with a minimum of disruption, organizations want to architect their networks to meet the connectivity and service requirements of these increasingly dynamic applications. They need to be policy-driven, programmable, scalable and automated to connect ideas to opportunities.
Juniper’s approach to Software Defined Networking allows you to evolve an open, agile and elastic infrastructure based on these principles:
- Freedom of Choice: Flexible deployment options allow implementation to be started anywhere in the network with the ability to grow and evolve over time. Multivendor support and seamless interoperability between physical and virtual elements avoids expensive vendor lock-in and allows best-of-breed choices that future-proof the infrastructure.
- Intelligent Automation: Insights based on data-derived knowledge of network operations guides automation decisions and closes the infrastructure provisioning feedback loop through a policy-driven, programmable infrastructure. Rich analytics collected from all infrastructure resources with correlations between virtual and physical layers improves measurement precision and visibility, capacity planning and optimization, troubleshooting, and network telemetry.
- Always-on Reliability: Support for business continuity and business-critical applications is gained through highly available, highly secure and seamlessly scalable software and hardware.
Networks built on these principles provide an ideal foundation for Juniper customers to build elastic clouds. Enterprises and service providers can evolve their infrastructure to private, public or hybrid cloud with support for multi-tenancy, self-service and operation orchestration and automation.
These networks are also the ideal platform for service providers to realize Network Function Virtualization (NFV). On this platform, you can dynamically create agile services that adjust configurations over a common resource pool, customize service combinations and chaining through policy automation, and allow service providers to greatly reduce operational complexities and risks, and time to revenue.
