Everything You Need to Know About SD-WAN

SD-WAN

SD-WAN is a technology that enables companies to manage and optimize their internet performance, collaboration, application performance, and security. It supports connectivity across different locations and working environments while providing centralized cloud-based delivery. It is particularly useful for companies that rely on cloud-based applications, as it enables automated and faster deployment. It also offers companies improved scalability and a framework for ongoing analysis and management.

Business-driven SD-WAN

A business-driven software defined WAN solution provides a range of benefits for IT professionals. It allows for easy network management, eliminates human error, and automates changes. Business-driven SD-WAN helps ensure optimal application performance and efficiency by adapting to network conditions and requisition changes. It also helps users access applications with minimal IT intervention.

Business-driven SD-WAN can actively use multiple forms of WAN transport and dynamically redirect traffic to a higher-performing link when necessary. This feature allows business-driven SD-WAN to reduce latency, packet loss, and security breaches while maximizing operational efficiency. Furthermore, it can handle a total transport outage with zero downtime, enabling sub-second failover of critical applications.

Overview

SD-WAN is a technology that can create a hybrid network that securely routes data through multiple connectivity modes. It can combine public broadband, leased lines, and even LTE/4G/5G connections. This gives businesses more options when it comes to communication. It can also automatically switch communications traffic when one option goes down.

One of the biggest benefits of SD-WAN is the ability to provide greater visibility into the network. This visibility can help you better understand how your network is being used and what applications are being offloaded. This visibility can help you right-size your network. It can also better understand how your traffic is offloaded to the Internet. Another benefit  is its ability to be integrated into CPE (Computer-Personal Equipment) solutions.

SD-WAN is available in both on-premises and cloud-based models. For enterprises, cloud-delivered SD-WAN can cut infrastructure costs and improve agility. In addition, zero-touch deployment reduces deployment times, while automation and orchestration improve IT productivity.

Cloud connectivity

Cloud connectivity can be a huge advantage for organizations. With SD-WAN, you can secure your connection to the cloud through a single management point. It also offers end-to-end performance backed by SLAs, security, and analytics. In addition, depending on your needs, It can provide a private link to multiple cloud service providers and data centers worldwide.

There are several options for establishing cloud connectivity, including public Internet access and private dedicated connections. The public Internet is the cheapest, while private dedicated connections cost more. Consider your specific needs and choose the option that best suits your organization.

Security

One of the main concerns with SD-WAN is security. Therefore, it is important to consider how the new architecture of the network will affect security. The attack surface will increase by shifting away from centralized internet gateways to distributed gateways. However, next-generation firewalls with unified threat management can make this transition seamless. Security features include automatic encryption, threat detection, and embedded firewalls.

Using a secure SD-WAN is essential to any business strategy, but it can pose some risks. The first is the potential for security breaches. Many SD-WAN solutions use public infrastructure, leaving data vulnerable. As such, a breach in a branch office router could result in the exfiltration of sensitive information.

Implementation

Implementing SD-WAN can help your business overcome many challenges traditional WANs face. By limiting the number of connections a business needs, SD-WAN can help cut operational expenses. In addition, its dynamic traffic management capabilities can help ensure that traffic is routed through the most efficient route, preventing the slowing of your network. SD-WAN also helps you increase application performance by identifying and allocating resources based on the application’s priority.

While a traditional MPLS connection may have provided the best network architecture in the past, network management has become more complex with the emergence of cloud computing and mobile workers. As a result, MPLS connections are no longer a perfect architecture, and WANs must evolve to keep up with the constant changes in IT. However, SD-WAN offers many advantages over traditional WANs, including simplified deployment and centralized management.

Cost

If you are considering SD-WAN for your organization, you may wonder how much it costs. Several factors must be considered, including the network infrastructure and application performance. For instance, internet connectivity is more cost-effective than MPLS but is not free. It also requires careful planning and clever migration techniques from MPLS to SD-WAN.

While SD-WAN isn’t cheap, it does provide many benefits, including lower staffing costs and simplified troubleshooting. In addition, with SD-WAN, you can avoid complex commands that lead to frustration. However, the higher tiers of SD-WAN may not be within the budget for small organizations, as the MRCs are expensive and recurring, and the equipment is expensive.
