One of the key decisions that IT teams face when implementing SDWAN solutions is whether to opt for a multi-vendor or single-vendor deployment strategy. This article explores the benefits and drawbacks of both approaches to help you make an informed decision about which one is right for your organization.

The Benefits of Multi-Vendor SDWAN Deployment

A multi-vendor SDWAN deployment involves using hardware and software from different vendors to build a network infrastructure. This approach offers several benefits, such as:

  • Flexibility: Multi-vendor SDWAN deployments give you the flexibility to choose the best hardware and software for your organization’s specific needs, without being tied to a single vendor.
  • Cost Savings: A multi-vendor approach can bring cost savings, as you can choose products and services based on their individual merits, thereby avoiding vendor lock-ins and premium prices.
  • Reduced Risk: By deploying multiple vendors, you can spread risk across different products and vendors, which can help mitigate exposure to common issues and vulnerabilities.

Another benefit of multi-vendor SDWAN deployment is improved performance. By using hardware and software from different vendors, you can take advantage of the strengths of each product to optimize your network performance. For example, you can use one vendor’s hardware for high-speed data transfer and another vendor’s software for advanced security features. This can result in a more efficient and effective network infrastructure that meets your organization’s specific needs.

The Advantages of Single-Vendor SDWAN Deployment

Single-vendor SDWAN deployments, on the other hand, involve using hardware and software from the same vendor to build a network infrastructure. This approach offers several benefits, such as:

  • Integration Ease: Single-vendor deployment simplifies integration of software, hardware components and features, ensuring compatibility across the network.
  • Reduced Management Overhead: With all SDWAN components from a single vendor,it simplifies ongoing management and maintenance, reducing maintenance overheads thereby reduces total cost of ownership (TCO).
  • Improved Security: A single-vendor SDWAN deployment model ensures all elements of the network are designed to work seamlessly and create a more secure network infrastructure.

Another advantage of single-vendor SDWAN deployment is the ease of troubleshooting. Since all components are from the same vendor, it is easier to identify and resolve issues that may arise within the network. This reduces downtime and ensures that the network is always up and running.

Furthermore, single-vendor SDWAN deployment allows for better control and customization of the network. With all components from the same vendor, it is easier to configure and customize the network to meet specific business needs. This ensures that the network is optimized for performance and can handle the demands of the business.

Understanding the Key Differences Between Multi-Vendor and Single-Vendor SDWAN Deployment

The main differences between a single-vendor and multi-vendor SDWAN deployment come down to choice, or lack thereof. With a single-vendor solution, the choice of hardware and software is predetermined, whereas a multi-vendor solution gives you the flexibility to choose from a range of different components to create your network infrastructure. As mentioned earlier, a multi-vendor approach can offer cost savings, flexibility and risk distribution.

Having said this, a single-vendor solution can offer better performance as the components are designed to work seamlessly with one another, which in turn makes it easier to configure and manage.

It is important to note that the decision between a single-vendor and multi-vendor SDWAN deployment ultimately depends on the specific needs and goals of your organization. If you prioritize cost savings and flexibility, a multi-vendor approach may be the best option. However, if performance and ease of management are your top priorities, a single-vendor solution may be the better choice. It is recommended to thoroughly evaluate both options and consult with experts before making a decision.

How to Choose Between Multi-Vendor and Single-Vendor SDWAN Deployment

Choosing between the two approaches depends on several factors that are unique to each organization. These are:

  • Business Requirements: Analyzing the business requirements such as bandwidth needs, application performance requirements and security needs of the organization before selecting the most suitable SDWAN deployment model.

  • Interoperability: Ensuring the components of your strategy work together seamlessly.
  • Scalability: Ensuring the components can scale as your network grows.

Another important factor to consider is cost. A single-vendor SDWAN deployment strategy may be more cost-effective as it eliminates the need for multiple vendor contracts and reduces the complexity of managing multiple vendors. However, a multi-vendor strategy may provide more flexibility in terms of choosing the best components for each specific use case, which can lead to better performance and cost savings in the long run.

Cost Savings and Efficiency Gains in Multi-Vendor SDWAN Deployments

One of the key drivers of multi-vendor SDWAN deployments is cost savings. By selecting individual components that offer the best performance and feature-set, organizations can reduce the costs associated with hardware and software licensing. Additionally, multi-vendor deployments increase competition and negotiate vendor rates, resulting in better cost-savings and efficiency gains.

Another advantage of multi-vendor SDWAN deployments is the ability to customize the network to meet specific business needs. Different vendors may offer unique features and capabilities that can be combined to create a tailored solution. This can result in increased efficiency and productivity, as well as improved user experience.

Furthermore, multi-vendor SDWAN deployments can provide greater flexibility and scalability. As business needs change and new technologies emerge, organizations can easily add or replace components without being locked into a single vendor’s solution. This can help future-proof the network and ensure that it remains competitive and up-to-date.

How Single-Vendor SDWAN Deployments Offer Improved Security and Reliability

A common concern with multi-vendor SDWAN deployments is security and reliability issues. When using different components that are not designed to work seamlessly together, there is always a risk of interoperability issues and security threats may arise.

Single-vendor SDWAN deployments overcome this challenge by integrating all components and creating a more secure and reliable network. By selecting defined vendor solutions with an established reputation, organizations can minimize the risks of security vulnerabilities and interoperability issues.
