Software Defined Networking (SDN) & Network Function Virtualization (NFV)
Today’s business and technology trends are driving the continued convergence of SDN and NFV. Today SDDC and NFV are the most common use case for SDN deployment. The move toward using software to create logical connections over physical devices and thereby virtualizing the infrastructure simplifies management, speeds delivery and can potentially reduce cost.
At Stratus, our first goal is to help organizations understand these trends and how they can benefit from them in the following ways:
- Centralized Management Flexibility: Network intelligence is logically centralized in the SDN controller software which maintains a global view of the network, allowing network topologies, applications, security and routing to be changed on the fly and to support micro-segmentation and multi-tenancy.
- Scalability: The ability to deploy network resources on demand ensuring optimum performance and reliability is crucial in today’s dynamic environments. Encapsulation, overlay, and intelligent parallel partitioning expand traditional VLAN capacity from 4096 isolated networks to a capacity of 16 million virtual networks in a VXLAN environment.
- Direct Programmability: By decoupling control functions from forwarding functions the network becomes directly programmable by proprietary or open source automation tools and platforms. This creates the ability to redirect traffic, apply dynamic traffic filters, apply QoS and dynamically adapt the network to applications and optimize traffic flows.
- Agility: SDN helps bring infrastructure and technology delivery capabilities in line with the rapid pace of continuous product development and business change.
- Elasticity: The ability of an IT infrastructure to quickly expand or reduce its capacity and services without hindering or jeopardizing the infrastructure’s stability, performance, security, governance or compliance protocols in a flexible high performing cost model.
- Security: SDN provides the ability to control security of both the network and applications from a common central facility and platform.
- Innovation: SDN assists organizations to rapidly create and deploy new applications and services, which can generate new revenue streams and customer value.
- Cap Ex Savings: SDN potentially limits the need to purchase purpose-built networking hardware, and instead supports elasticity and on-demand provisioning.
- Op Ex Savings: SDN enables logical, programmatic control of the network making it easier to design, deploy, manage, and scale. Furthermore, automation of provisioning and orchestration reduces management cost and optimizes network availability and reliability.
Our experience with industry leading solutions and platforms includes:
Cisco Application Centric Infrastructure (ACI)™
Cisco ACI™ is a highly scalable, multipath, high-performance leaf-and-spine architecture which provides a Virtual Extensible LAN (VXLAN) overlay for the network used by the business applications, departments, and customers.
NSX™ enables the creation of entire networks in software and embeds them in the hypervisor layer, abstracted from the underlying physical hardware. All network components can be provisioned in minutes, without the need to modify the application.
Juniper Contrail™ & OpenContrail™
Contrail Controller™ from Juniper Networks is an open cloud network automation product that uses software-defined networking (SDN) technology to orchestrate the creation of virtual networks with high scalability. It brings together a scale-out framework and physical routers and switches to scale infrastructures beyond data center boundaries in order to offer workload mobility in a hybrid environment.
