In recent years, with the ever-increasing need for businesses to have reliable and efficient connectivity, software-defined wide area network (SDWAN) has emerged as a popular solution. SDWAN eliminates the need for private links and provides secure, cost-effective connectivity over any available network. However, when it comes to deployment, businesses have two options: regional SDWAN deployment or global SDWAN deployment. In this article, we’ll compare and contrast the two deployment models and explore the benefits they offer.

What is SDWAN and how does it work?

Before delving into the two deployment models, it is important to discuss what SDWAN is and how it works. SDWAN technology enables businesses to create a wide-area network over more than one carrier with different types of links such as broadband, 4G/5G, WAN circuits, or MPLS connections. It uses virtual pools of network resources that are easy to configure, monitor, and manage from a central location. SDWAN technology enables network administrators to configure policies to ensure the optimal performance of the network. It also provides secure connectivity by encrypting traffic end to end, which enhances data privacy and security.

One of the key benefits of SDWAN technology is its ability to improve network performance and reduce latency. This is achieved through the use of intelligent routing, which allows traffic to be dynamically routed over the most optimal path based on factors such as network congestion, link quality, and application requirements. SDWAN also provides visibility into network performance, allowing administrators to identify and troubleshoot issues quickly. Additionally, SDWAN can help reduce costs by enabling businesses to use lower-cost broadband connections in place of more expensive MPLS circuits, without sacrificing performance or security.

Understanding the benefits of SDWAN deployment

SDWAN has various benefits that make it a preferred solution for businesses. First and foremost, it offers reduced costs since it eliminates the need for expensive private links and allows businesses to rely on internet connections, which are widely available and cost-effective. Secondly, it provides faster deployment and reduces time to market for businesses. Thirdly, it offers enhanced security with end-to-end encryption, which ensures data privacy and prevents cyber threats. Lastly, it enhances network visibility and control, enabling businesses to monitor their network traffic and manage bandwidth usage easily.

Another benefit of SDWAN deployment is its ability to optimize network performance. SDWAN can prioritize critical applications and allocate bandwidth accordingly, ensuring that they receive the necessary resources to function optimally. This results in improved application performance and user experience. Additionally, SDWAN can dynamically route traffic based on network conditions, ensuring that traffic is always taking the most efficient path. This results in reduced latency and packet loss, which can further improve application performance. Overall, SDWAN deployment can significantly improve network performance and user experience, making it a valuable investment for businesses.

Why choose regional SDWAN deployment over global SDWAN deployment?

Regional SDWAN deployment involves deploying the solution across a specific geographic area, such as a city or state. This model is ideal for businesses with a limited budget or those that need to create separate networks for different locations. Regional SDWAN deployment is beneficial because it allows businesses to have more control over the network and provides an isolated environment for each location, which enhances security and reduces network congestion. Additionally, regional SDWAN deployment is easy to deploy and manage since it involves a smaller scope than global SDWAN deployment.

Another advantage of regional SDWAN deployment is that it can be customized to meet the specific needs of each location. For example, if one location requires more bandwidth than another, the network can be configured to allocate more resources to that location. This level of customization is not possible with global SDWAN deployment, which typically involves a one-size-fits-all approach.

Furthermore, regional SDWAN deployment can be more cost-effective in the long run. While global SDWAN deployment may seem like the better option for businesses with multiple locations, the cost of maintaining and managing a global network can quickly add up. With regional SDWAN deployment, businesses can save money by only paying for the resources they need for each location, rather than investing in a large, complex network that may not be necessary.

Advantages of regional SDWAN deployment for small and medium businesses

Small and medium businesses (SMBs) often have limited IT resources and budgets, and therefore, face a challenge when it comes to implementing a wide-area network. Regional SDWAN deployment is ideal for these types of businesses because it provides a cost-effective, scalable and efficient solution. With SDWAN, SMBs can have centralized management, which simplifies network management, reduces network complexity, and improves network performance. Additionally, SDWAN deployment offers application-specific routing that improves overall application performance and ensures that mission-critical applications receive priority.

Another advantage of regional SDWAN deployment for SMBs is the ability to easily add new locations to the network. With traditional WAN solutions, adding a new location can be a complex and time-consuming process. However, with SDWAN, new locations can be quickly and easily added to the network, allowing SMBs to expand their business without worrying about network limitations.

Furthermore, regional SDWAN deployment provides enhanced security features that protect SMBs from cyber threats. SDWAN solutions offer end-to-end encryption, which ensures that data is secure as it travels across the network. Additionally, SDWAN solutions can detect and mitigate security threats in real-time, providing SMBs with peace of mind that their network is secure.

Global SDWAN deployment: Is it worth the investment?

In contrast, global SDWAN deployment is ideal for larger businesses that have multiple locations globally. This model involves deploying the solution across different geographies and provides seamless connectivity for all locations. Global SDWAN deployment is beneficial because it offers reduced network costs and enhanced user experience since it eliminates network bottlenecks and reduces latency. Additionally, global SDWAN deployment provides a centralized management system that simplifies network management, which is especially important for businesses with remote locations. Lastly, global SDWAN deployment is ideal for businesses with mission-critical applications that require high bandwidth, low latency, and high-quality performance.

Another advantage of global SDWAN deployment is that it provides better security for businesses. With the increasing number of cyber threats, businesses need to ensure that their network is secure. Global SDWAN deployment offers advanced security features such as encryption, firewalls, and intrusion detection and prevention systems. These security features help to protect the network from cyber attacks and ensure that sensitive data is kept safe. Therefore, investing in global SDWAN deployment not only enhances network performance but also provides better security for businesses.

Comparing the costs of regional vs global SDWAN deployment

While SDWAN deployment offers reduced network costs, businesses must consider the upfront costs and ongoing costs of each deployment model. For regional SDWAN deployment, the initial deployment cost is lower since it involves a smaller scope. However, the ongoing support and maintenance costs may be higher since each location requires separate management. For global SDWAN deployment, the initial deployment cost may be higher since it involves a larger scope. However, the ongoing support and maintenance costs are lower since it offers centralized management. Ultimately, the costs of each model depend on the business’s specific needs and budget.

Another factor to consider when comparing regional and global SDWAN deployment is the level of control and customization. With regional deployment, businesses have more control over each location’s network configuration and can customize it to meet specific needs. However, this level of control can also lead to more complexity and potential errors. On the other hand, global deployment offers a more standardized network configuration, which can simplify management and reduce the risk of errors. However, this may limit the ability to customize the network to meet specific needs.

It’s also important to consider the scalability of each deployment model. Regional deployment may be more suitable for businesses with a smaller number of locations, while global deployment may be necessary for larger businesses with a global presence.
