Software-Defined Wide Area Network, or SDWAN, has emerged as a game-changer in the networking world, especially for businesses that rely on cloud-based applications. It enables businesses to optimize their network traffic and enhance the performance of cloud applications while reducing overall networking costs. However, one of the significant decisions businesses need to make when implementing SDWAN is whether to deploy it on a private cloud or public cloud. In this article, we will explore the differences between private cloud SDWAN deployment and public cloud SDWAN deployment, evaluate the pros and cons of each approach, and provide expert recommendations on selecting the best approach for your business.

What is SDWAN and why is it important for cloud-based networks?

SDWAN is a networking technology that enables businesses to connect their branch offices through multiple communication channels, including broadband, 4G/LTE, and MPLS. It enhances network performance by intelligently routing traffic based on specific application requirements. SDWAN simplifies network management and reduces networking costs by allowing businesses to use multiple low-cost broadband links instead of expensive MPLS links.

For cloud-based applications, SDWAN is particularly important because it improves application performance by reducing latency and packet loss. It also enables businesses to enhance their network security by encrypting traffic and segregating it from other traffic. With SDWAN, businesses can ensure high-quality cloud application performance on any network, including public and private cloud networks.

Moreover, SDWAN provides businesses with greater visibility and control over their network traffic. It allows businesses to monitor and manage their network traffic in real-time, enabling them to identify and resolve issues quickly. This is especially important for cloud-based networks, where businesses need to ensure that their applications are running smoothly and efficiently. With SDWAN, businesses can easily prioritize their network traffic, ensuring that critical applications receive the necessary bandwidth and resources to function optimally.

Understanding the difference between private and public cloud SDWAN deployment

Private cloud SDWAN deployment refers to deploying SDWAN on private cloud infrastructure, which is a dedicated cloud environment that is hosted and managed by the business. Private cloud infrastructure provides greater control and security of the SDWAN environment, but it comes with higher costs and administrative overhead. In contrast, public cloud SDWAN deployment refers to deploying SDWAN on a public cloud environment, which is provided by third-party cloud providers such as Amazon Web Services, Microsoft Azure, or Google Cloud. Public cloud infrastructure provides greater scalability and flexibility, but it may not offer the same level of control and security as private cloud infrastructure.

When deciding between private and public cloud SDWAN deployment, businesses must consider their specific needs and priorities.
