What is SD-WAN?
SD-WAN stands for Software Defined Wide Area Network. SD-WAN is a virtual network architecture that allows organizations to leverage multiple transport services such as Broadband, MPLS and LTE (5G/Wi-Fi) to securely connect data centers to branch offices and users to applications and services. The Software Defined (SDN) network separates the control plane from the data plane allowing for enhanced agility, manageability and complete visibility of the network. SD-WAN provides enhanced security, optimized performance, lower costs, and ease of deployment and management. An SD-WAN solution will enhance application performance, user productivity, reduce network expenses, unify network connectivity, and enable orchestration of application delivery across your network.
How Does SD-WAN Work?
SD-WAN utilizes a centralized controller that incorporates user defined application and routing policies to provide highly secure, dynamic, application-aware network traffic management. The SD-WAN utilizes the existing network underlay connectivity such as Broadband, MPLS and LTE and routes the data within the network using highly secure overlay tunnels that are encrypted. SD-WAN monitors the performance of the network and dynamically routes network traffic based on the QoS and SLA objectives for optimum connectivity of users to applications and services. This level of control allows for optimal delivery paths across any combination of network transport types. SD-WAN improves your TCO and makes the WAN much easier to deploy and manage.
Top Features of an SD-WAN Solution
Dynamic Path Selection & Transport
SD-WANs use dynamic path selection to steer or route network traffic to one or multiple WAN links based on priority, network conditions or traffic patterns. Data packets are automatically steered to specific WAN links based on link availability, to balance network traffic…
SD-WAN allows network administrators to centrally manage their entire network fabric by pushing out policies to all the branches with ease. This also allows for quicker integration of new branches. Administrators can also have a full view of the network, leading to the possibility of…
SD-WAN, at its core, supplies an organization’s network with a secure fabric to trusted devices while leveraging insecure connectivity, such as the Internet. SD-WAN has in-built security features as well, such as stateful firewalls, IPS/IDS Intrusion Prevention System/Intrusion Detection…
SD-WAN empowers organizations with the freedom to connect branches directly to a corporate data center and directly to cloud services such as SaaS applications. Connecting to cloud services has the added benefit of not requiring the traffic to route through the corporate data center…
Policy Based Management
The SD-WAN steers data based on policies (Quality of Service) configured specifically for your applications, devices, users, groups, locations and more. These polices are configured with a priority setting in which the SDWAN utilizes to prioritize the data packets and how they are dynamically…
Enterprise SD-WANs supports a secure true zero-touch provisioning of edge controllers. In order to onboard a device in a remote location the only required steps are to unbox the edge controller, plug it in and connect it to the internet. The edge controllers are automatically provisioned…
Improved Network Performance
SD-WAN brings awareness of traffic types that traverse through your network. An IT manager can prioritize traffic from business-critical applications as well as other services such as VoIP and web-conferencing and help steer the traffic via the most efficient route…
SD-WAN reduces overall costs by allowing the use of low cost alternatives to expensive MPLS such as the public internet, broadband and LTE networks, allowing direct cloud access for the increasing use of SaaS applications, getting better results from available…
The use of SaaS applications and other cloud services are on the rise. SD-WAN facilitates cloud access throughout the network fabric, including branch offices and remote workers, which in turn removes the need to route cloud and remote traffic back through the corporate data center…
Introduction to SD-WAN
SD-WAN Director Deployment Options
AmZetta partners with Managed Service Providers (MSPs) for Customers that prefer to hand off the implementation, configuration and management of the SD-WAN network. AmZetta Partners can quickly and securely implement the SD-WAN solution using a team of highly skilled engineers. Managed Services avoids upfront investments and allows the network to be fully managed by a team of experts.
Customers running applications and services on-premise or in local data centers prefer to host the SD-WAN solution within their infrastructure. AmZetta provides an On-Prem SD-WAN solution that allows 100% total control and management to be performed by the in-house IT staff. AmZetta Solutions Engineering will remotely assist Customers in setup, configuration and management of the On-Prem SD-WAN.
Not everyone is comfortable managing their SD-WAN network. AmZetta offers a Co-Managed SD-WAN solution where you retain 100% control over the SD-WAN while it is hosted within the AmZetta Cloud. AmZetta will configure and train your IT team on the SD-WAN Director to handle the day-to-day network operations. AmZetta will provide backend support and maintenance of the SD-WAN network.
