If you hear frequent complaints from your staff about slow performance, your business is frequently at or above your bandwidth limits, or you already know you can’t adopt more cloud solutions because your network can’t handle them, it’s time to have “the talk” about WAN (wide area network) optimization.
The bad news — it’s time to acknowledge the fact that your network is seriously holding you back, and you’ve probably already been throwing good money after bad in terms of additional bandwidth, hardware, IT support, and productivity losses. But you have more options than ever before. In this blog, I’ll explore updates for almost any budget.
Business Connectivity Tweaks on a Budget
Need to tackle other improvements in 2025 first? Here’s what you might try — if you haven’t already — to get more life out of the network you have.
Increase Your Bandwidth
If you’re constantly running across bandwidth limitations, that’s probably not going to get better on its own. Work with your provider to see what you can do to handle increased traffic. Yes, you’ll probably pay more, but the constant drain on your productivity isn’t worth it. And it’s probably frustrating your staff more than you think.
Optimize Your Network for Cloud Computing
Cloud computing tools make life so much easier, but they can cause some serious network congestion on networks that weren’t designed to handle them. But there are a few things you can do to help route traffic, like implementing policies to steer software as a service (SaaS) traffic directly, using local internet breakouts at remote sites, and prioritizing performance for the most critical cloud solutions. You might also try a WAN accelerator that will compress, cache, and guide traffic.
Add Cloud-Integrated Security
You might also try integrating cloud-based security services directly into your network architecture instead of backhauling your traffic through your data center. That way, you’ll get the consistent security enforcement you need without yet another drag on your system.
Use Cloud-Native Services
Cloud-native networking services like Azure Virtual WAN can go a long way toward simplifying WAN management. You’ll be able to get more control over your network without overloading IT staff.
Probably Your Best Option: Migrating to SD-WAN
A software-defined WAN (SD-WAN for short) shifts more control over your network into the cloud using software. If you want to adopt more cloud collaboration and cloud security solutions in the future, you’ll need to migrate eventually. Fortunately, once you do, you can get increased performance for a fraction of the cost.
How Does a Software-Defined WAN Increase Performance?
Essentially, software-defined networking creates a more efficient way to send and retrieve information between data centers or remote locations. The technology isn’t new, but with the rise of cloud computing solutions post-pandemic, it’s becoming indispensable for organizations that rely on their internet connectivity and performance for day-to-day workflows.
The Traffic Analogy
Today, most organizations only route traffic to the second line, seen as a backup line, in the case of a failure. It’s a manual process. The traditional model operates like a stop sign, with only a go or no-go option. You see that it is either working or it is not.
A Managed SD-WAN is more like a stoplight. It adds a “yellow light” to allow you to receive alerts, identify issues, and fix them before anything fails and you see a “red light.”
The Benefits of Software-Defined Networking
An SD-WAN gives organizations more flexibility. For example, you can buy two internet circuits and combine them to balance their loads for half the cost. With a software-defined WAN, your business can also rely more on public broadband and less on private links. Public broadband circuits don't provide quality guarantees, so your SD-WAN will take measurements between locations to assess whether the broadband link is capable of carrying traffic, like voice or video, reliably. Additionally, organizations can use multiple carriers for their internet lines, giving them more redundancy and improved performance.
However, the biggest advantage is a network that manages the traffic intelligently, dynamically and even automatically based on a set of parameters. For example, when traffic reaches a certain volume threshold on a certain path, data can be automatically routed to the other line.
The Drawbacks of Migrating to SD-WAN
SD-WAN technology is not easy to implement. Making it all work together takes a significant amount of programming by a highly skilled IT professional and coordination with multiple vendors. It also requires an upfront investment in specialized hardware.
However, when the adoption challenges are overcome, SD-WAN provides the ability to deliver more simplicity, automation, and agility for businesses at a compelling cost.
