Centralization of applications at large scale in a consolidated data center, and the increasing size of software-as-a-service application deployments, creates the need to deploy thousands of 1GbE/10GbE ports to connect to servers and storage devices in the data center. Service providers need a way to terminate application servers without having to build layers of separately managed networking devices. They also need to be able to configure services from a central location and automate the provisioning of their network devices. This is driving the need for a device-based solution that can control thousands of network ports from a single point and that can interface with service orchestration systems.
A number of trends—including the consumerization of IT, cloud computing, and social media— present significant opportunities for businesses to improve productivity. Before adopting these technologies, however, organizations try to fully understand the impact they will have on the underlying infrastructure and, more specifically, the network environment, since it is a critical enabler for all of these services. As a result organizations are looking to innovation in the network to meet their business needs.
There is a train of thought that is popular with some network vendors and long time network engineers that there is a compelling need to “orchestrate” the physical network and the virtualised-networking world. This is mostly expressed as a desire to ensure that VLANs are synchronised between the physical network switches and the virtual switches on the virtualisation hosts.
The importance of the network continues to grow and innovation in the network needs to support new businesses models, and drive social and economic change. SDN is about adding value and solving a problem that has not been solved. SDN will help address challenges currently faced by the network as it evolves to support business applications. It is worthwhile to step back and determine what the big-picture problem is to be solved. It is about helping network operators to combine best-of-breed networking equipment with SDN control to facilitate cost effective networks that provide new business opportunities. This is key to Juniper’s strategy. I’d like to elaborate on a few key points.
Big Data Analytics is a trend that is changing the way businesses gather intelligence and evaluate their operations. Driven by a combination of technology innovation, maturing open source software, commodity hardware, ubiquitous social networking and pervasive mobile devices, the rise of big data has created an inflection point across all verticals, such as financial services, public sector and health care, that must be addressed in order for organizations to do business effectively and economically.
In my previous blog (link) I wrote about the New Network Platform Architecture and how Juniper is delivering network designs that will enable our customers to optimize their network investments. With these designs Juniper’s goal is to help customers overcome technology limitations so that they can deliver greater efficiency, and increased business value, by leveraging their networks more effectively. To this end Juniper has released the Juniper Networks Horizontal Campus Validated Design Guide.
