Everything you need to know about SD-WAN


What is SD-WAN?
SD-WAN, or Software-Defined Wide Area Networking, is a revolutionary technology that simplifies IT infrastructure control and management. It delivers a virtual WAN architecture that securely connects users to their applications, providing unparalleled agility and cost savings to networking. SD-WAN is designed to solve many of the challenges associated with traditional WAN design, such as high costs, complexity, and limited scalability.
SD-WAN is a type of networking technology that uses software-defined networking (SDN) principles to manage and optimize the performance of wide area networks (WANs). It enables organizations to securely connect users, applications, and data across multiple locations while providing improved performance, reliability, and scalability. SD-WAN simplifies the management of WANs by providing centralized control and visibility over the entire network
A Smarter, More Secure Network Performance for the Cloud Era
Businesses today require secure, high-performance connectivity to support cloud applications, remote work, and multiple locations, ensuring optimal network performance. Traditional WAN architectures struggle with network inefficiencies, security vulnerabilities, and high costs.
SD-WAN enhances network security by integrating security functions into the cloud-based solution, providing more efficient and centralized management.
SD-WAN (Software-Defined Wide Area Networking) is a modern networking solution that optimizes traffic routing, security, and cloud connectivity—reducing complexity while enhancing performance.
Momentum’s AI-driven SD-WAN, powered by Juniper Mist, goes beyond traditional SD-WAN by incorporating proactive AI-driven automation to improve reliability, security, and operational efficiency.
Why SD-WAN?
The Challenges of Traditional WAN Optimization
Legacy WAN networks rely on fixed, hardware-based routing, making them:
- Expensive to scale across multiple locations
- Inefficient in managing cloud and SaaS applications
- Difficult to troubleshoot, requiring heavy IT involvement
- Vulnerable to performance issues and security threats
In contrast, SD-WAN technology offers a more flexible and cost-effective solution, enhancing user experience, securing cloud access, and addressing modern IT network challenges, particularly for organizations with distributed infrastructures.
Momentum’s AI-driven SD-WAN solution addresses these challenges by intelligently managing traffic, automating troubleshooting, and ensuring optimal cloud performance for applications like Microsoft 365, Zoom, and AWS.
SD-WAN vs. MPLS
SD-WAN is often compared to traditional MPLS (Multiprotocol Label Switching) networks. While MPLS is a reliable and secure technology, it can be expensive and inflexible. SD-WAN, on the other hand, offers a more cost-effective and agile solution for WAN connectivity. SD-WAN can provision new links in days, whereas MPLS can take weeks or months. Additionally, SD-WAN provides policy-based routing, which allows traffic to be optimally sent through the network based on the needs of the underlying application.

Who benefits from SD-WAN?
SD-WAN is essential for businesses that need secure, high-performance network connectivity across multiple locations. SD-WANs provide better performance, cost-effectiveness, scalability, and support for cloud adoption, making them a superior alternative to traditional networking solutions like VPN and MPLS.

Retail
Retailers benefit from SD-WAN by ensuring secure, high-speed transactions and seamless inventory management. With cloud-based POS systems and real-time inventory tracking, retail businesses can improve operational efficiency while maintaining PCI DSS compliance for secure financial transactions. The ability to provide customers with a smooth shopping experience, both in-store and online, makes SD-WAN a crucial component in the retail sector.

In healthcare, SD-WAN supports encrypted, HIPAA-compliant communications, ensuring the safe transfer of patient data. With the rise of telemedicine, hospitals and clinics require low-latency, high-bandwidth connections to facilitate virtual consultations without interruption. Additionally, SD-WAN enables seamless access to cloud-based Electronic Health Records (EHRs), allowing medical professionals to retrieve and update patient information securely from any location
Finance
Financial institutions, including banks and fintech companies, rely on SD-WAN for secure, high-speed data transmission. Low-latency connections are essential for real-time financial transactions, stock trading, and banking operations. With built-in encryption and advanced security measures, SD-WAN safeguards against cyber threats while optimizing network performance for cloud-based financial applications.
Remote and Hybrid Work
For remote and hybrid workforces, SD-WAN provides reliable and secure access to cloud-based applications, reducing dependence on traditional VPNs while maintaining enterprise-grade security. Employees working from home or satellite offices benefit from optimized bandwidth allocation, reduced latency, and improved access to collaboration tools like Microsoft 365, Zoom, and Google Workspace. This ensures a seamless work experience regardless of location.
Advantages of Operator Connect
Keep your existing carriers
If you’re already working with an Operator Connect Partner as your carrier, you’ll be able to retain your current relationships, pricing, and contracts. You’ll also keep your current business numbers, with no porting required to integrate them into the Microsoft Teams phone system. Most leading carriers and PSTN providers are already vetted and approved by Microsoft.
Cost-effective calling
Operator Connect is generally viewed as the most cost-effective way for a business to add PSTN functionality to its Teams deployment. It’s important to note, however, that Operator Connect Partners maintain many different pricing models. Choosing the wrong provider could potentially undercut any savings gained from using the service.
There are a few factors which together make Operator Connect so efficient from a budget standpoint:
- Minimal hardware requirements leading to reduced hardware spending.
- Less time, effort, and resources spent configuring voice for Teams.
- Dynamic scaling.
- No need to maintain or support on-premises hardware.
Simple configuration, deployment, and management
Administrators can connect third-party carriers to Teams via an interface which also allows them to handle user management, provisioning, and de-provisioning. There’s no coding or PowerShell knowledge required on the backend; everything is simple enough that even a business with no IT professionals can understand and leverage it.
Expert partnerships
Using Operator Connect allows an organization to benefit from their PSTN provider’s comprehensive professional expertise. Many providers also track and report usage on the behalf of their clientele, enabling businesses to identify possible bottlenecks in their deployment.
Enhanced networking
Operator Connect also provides at least some guarantee of connectivity, as clients are connected to both their carrier’s and Microsoft’s infrastructure. Coverage for Operator Connect typically spans a more comprehensive area compared to its alternatives, as well. Most importantly, because Microsoft holds its Operator Connect Partners to such a high standard, Operator Connect Partners typically provide superior security coupled with an excellent service-level agreement.
Disadvantages of Operator Connect
May require additional licensing
Operator Connect isn’t something you can use straight out of the box with your other Microsoft products. In order to deploy and leverage the service, you may need to purchase additional licenses. At the minimum, this includes a basic Teams license, a Microsoft Phone System license, and a PSTN add-on. The price of these licenses together typically starts around $22.50 per user per month. Less expensive than many alternatives, certainly — but still by no means free.
Less customization
Operator Connect is a highly flexible service in its own right. However, it offers less customizability compared to its predecessor, Direct Routing. This means that if your organization needs to accommodate complex telecommunications needs, you may find Operator Connect somewhat lacking. The service’s reduced complexity also renders it slightly less versatile.
Limited carrier choices
Because Microsoft has incredibly stringent requirements for its list of approved carriers, your options are naturally somewhat more limited with Operator Connect than with other choices. In most cases, if your carrier of choice doesn’t appear on that list, you’re out of luck. With that said, most major carriers are also approved.

Microsoft Operator Connect
Operator Connect is the more hands-off version when compared to Direct Routing. With Operator Connect, businesses can access all the best features of a Microsoft Teams-enabled phone system without the complexity. Adding new users, porting numbers, and making account changes are all done through an intuitive dashboard.
Teams Direct Routing
Direct Routing lets you choose any PSTN carrier, while Operator Connect restricts you to approved partners. It’s more complex, making it ideal for larger enterprises with specific infrastructure needs and greater control over their Teams Phone environment.
Teams Calling Plans
This option replaces both Operator Connect and Direct Routing, making Microsoft your carrier. You’ll need to cancel any existing contracts and pay Microsoft’s rates. Calling Plans work well for smaller organizations needing inbound calls but can be inefficient for larger teams with high usage.
- Do you need advanced control and configuration options due to your unique requirements?
- Does your IT staff or managed service provider have the necessary expertise to manage Direct Routing’s complexity?
- Is your existing carrier an Operator Connect Partner?
- Do you still want to maintain on-premises hardware?
- Does Operator Connect meet your coverage requirements?
