A Software-defined Wide Area Network (SD-WAN) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, LTE and broadband internet services – to securely connect users to applications.
Traditional WAN design is based on multiple devices stacked in the branch office with siloed management and disparate WAN links connecting them.
Limited bandwidth of expensive private/MPLS circuits inhibits rollout and impacts performance of applications. At the same time, private/MPLS WAN redundancy is complex to deploy and manage
With no direct access to cloud resources from the branch with the archaic hub and spoke network design, the traffic is backhauled through the enterprise datacenter with heavy performance penalties
Application traffic over Internet links lacks SLAs for predictable performance. Every change in the application quality of service requires manual changes across the branches and the datacenter.
Traditional WAN includes multitude of single-function devices and appliances connecting via different WAN links. This infrastructure sprawl causes complexity of branch IT management.
SD-WAN provides a software abstraction to create a secure, reliable, and transport-independent network overlay and decouples networking software services from the underlying hardware. SD-WAN architecture comprises of – securing network overlay, scalable secure cloud network, virtual service delivery, orchestration and analytics.
Provision branch offices in minutes with automated zero-touch deployment. Centrally manage your WAN from the cloud with global visibility and remediation control. Scale quickly with automation, outcome-driven policies, and end-to-end analytics.
Directly access SaaS, hybrid and multi-cloud through gateway as a service. Enable easy cloud adoption with managed on-ramp to any cloud. Reduce latency to cloud workloads with no data center backhaul.
Optimize application access performance over any type of WAN link with the intrinsic ability to determine deliver content across multiple transports.. Deliver desired quality for business-critical applications through policy-based prioritization, intelligent traffic steering, continuous link monitoring, and dynamic remediation.
Customize and enforce intelligent security policies throughout the entire network. Easily insert third-party firewall and cloud security services in any traffic route. Protect, prioritize, and isolate traffic via the zero-trust model and end-to-end segmentation.
Many enterprise networks utilize a primary and secondary circuit to deliver continued performance in the case of an outage. But the secondary “backup” circuit sits idle, and is only utilized when the main circuit goes down. Outages still cause a temporary disruption, and you pay for capacity that you hope you never use. With a properly configured SD-WAN, “backup” circuits are a thing of the past, because secondary circuits are no longer sitting idle.
And whether you want to deploy SD-WAN yourself, or enlist a managed service, Netology can help you create the best solution for your business, while potentially saving you money.
Networks were managed at the individual router level.
Routing decisions were limited to packet header information.
Load balancing was static and primitive.
Excessive latency, packet loss, and jitter degraded application performance and frustrated users. Manual intervention was required.
Traffic shaping was complex and tedious to design and implement.
Failover required seconds.
Networks are managed via a central orchestrator.
Routing decisions can be tailored for specific applications.
Excessive latency, packet loss, and jitter are automatically detected and mitigated before application performance degrades.
Load balancing is dynamic and intelligent.
Traffic shaping is easily configured per application.
Failover is instantaneous.
