What is SD-WAN?
SD-WAN is a type of network technology that uses software to abstract the underlying network hardware, providing flexibility in configuring and managing WAN connections. It allows for improved application performance, reliability, and scalability. Essentially, SD-WAN works by routing traffic over multiple circuits, including MPLS, broadband, and LTE, while allowing for real-time monitoring and analytics of the traffic that is being sent. This allows administrators to take advantage of the cost savings associated with deploying SD-WAN while providing improved performance and reliability.
Requirements for Deployment
There are several key requirements that must be considered when deploying an SD-WAN solution. The first requirement is the selection of appropriate hardware. In order to ensure optimal performance, it is essential that the hardware used is designed for the SD-WAN solution and capable of handling the expected traffic load. Additionally, any device used should be compliant with the relevant security standards.
Second, companies must consider their existing network. Organizations must determine what type of network will best serve their needs, such as whether to use MPLS, broadband, or LTE to connect sites. This will depend largely on factors such as budget, geography, and the type of applications that are being deployed. Additionally, organizations must consider any existing network performance issues when deploying an SD-WAN solution.
Third, companies must select an appropriate software solution. When selecting an SD-WAN solution, organizations should consider the features and capabilities that are available and choose a solution that meets their specific needs. This could include features such as automated provisioning, centralized management, real-time analytics, and application-aware routing.
Fourth, organizations should ensure their chosen solution is integrated with other existing technology. This includes integrating with any on-premises or cloud-based applications, as well as security solutions. It is important to ensure that the SD-WAN solution is properly integrated in order to take full advantage of the benefits and features of the solution.
Finally, companies must deploy the solution in an efficient and secure manner. This includes ensuring the effective configuration and deployment of the SD-WAN solution and the setup of secure connections between sites. It is also important to ensure the solution is optimized to meet the specific needs of the organization.
Best Practices
In order to ensure the successful deployment of an SD-WAN solution, organizations should adopt the following best practices:
• Thoroughly evaluate potential solutions: Companies should carefully research and evaluate potential solutions to ensure they choose one that meets their specific requirements.
• Perform testing: After selecting a solution, organizations should perform rigorous testing to ensure the solution performs as expected.
• Automate when possible: Automation is key for streamlining the deployment process and ensuring optimal performance. Organizations should take advantage of automated features and capabilities wherever possible.
• Monitor performance: Organizations should monitor the performance of their SD-WAN solution to ensure performance remains optimal. This includes both real-time monitoring and regular assessments.
Conclusion
Deploying an SD-WAN solution can provide organizations with improved performance, scalability, and cost savings. However, in order to ensure the successful deployment of an SD-WAN solution, organizations must consider the various requirements including hardware selection, network evaluation, software selection, integration, and secure deployment. By adopting the best practices outlined above, organizations can ensure the successful deployment of an SD-WAN solution and realize the full benefits of the technology.
