If you’re wondering how SD-WAN will change your business strategies, you’ve come to the right place. In this article, you’ll learn about centralized network orchestration, Application-specific performance, and Cloud migration initiatives. These are just a few of the many benefits of SD-WAN s o you must learn about SD-WAN.
Centralized Network Orchestration
Centralized network orchestration helps enterprises deliver new network services quickly. It reduces deployment and management complexity, enabling customers to access applications and data when needed. SD-WAN also allows centralized management and risk assessment and can automate and centralize the monitoring and troubleshooting of network devices.
In addition to providing centralized network orchestration, SD-WAN solutions combine security and networking functions for greater flexibility and reliability. This approach allows organizations to offer enterprise services and benefits to their users while leveraging commodity hardware and lightweight CPE equipment. This means that enterprises are more efficient and able to meet the demands of the modern IT landscape.
Unlike legacy WANs, SD-WAN also provides a centralized view of application traffic flows and enables administrators to make necessary changes based on the needs of the business. This gives IT greater visibility and control, making it easier to meet business goals. The software offers real-time visibility and control over traffic throughput, latency, and jitter across overlays. Moreover, it allows enterprises to automate security and application policies across hundreds of thousands of sites.
Real-Time Traffic Management
Real-time traffic management in SD-WAN enables businesses to prioritize traffic for mission-critical or real-time data services. Prioritizing certain types of traffic across the WAN helps organizations avoid bottlenecks and increase the speed of critical traffic, resulting in improved customer experience. Traffic prioritization ensures that essential applications can be delivered with minimum downtime. This feature also helps businesses manage security and compliance policies by enforcing the appropriate QoS.
For example, the Cisco SD-WAN platform integrates with ThousandEyes for end-to-end visibility and application experience. This integration uses artificial intelligence (AI) for IT operations, enabling it to analyze networks and recommend improvements to increase reliability and security. The solution also deploys agents to the internet and the cloud, delivering operational insights.
Real-time traffic management in SD-WAN also helps to monitor network performance and identify problem areas. The IT team can quickly address problems without end users knowing about them. An IT professional can quickly troubleshoot issues with the help of these tools. Ultimately, the speed of NOC resolution is crucial.
Unlike traditional WAN architecture, which assumes that applications are hosted in the central data center, SD-WAN enables data transport directly to the cloud, where the applications reside. This reduces overall network costs and improves efficiency. It also gives end users real-time visibility into network health and makes decisions about the best traffic routing.
The quality and amount of data collected are critical to network optimization. A good solution provides granular, detailed data capture and scalable data storage. But capturing data is only the first step. The data must also be retained long enough to identify historical performance trends. Furthermore, it must provide real-time performance visibility to network administrators, enabling them to make real-time adjustments.
SD-WAN also helps reduce network administration costs. The centralized management of SD-WAN minimizes the need for network experts to travel to remote sites. This frees them to do more meaningful work in the office. It allows IT teams to meet demanding schedules. Additionally, SD-WAN allows network engineers to respond quickly to requests and make changes to existing services. This makes it possible to complete tasks that once took hours or days.
Cloud Migration Initiatives
To fully take advantage of the benefits of SD-WAN, enterprises need to choose a solution that provides both flexibility and service sophistication. Enterprises can select software-only solutions that offer the flexibility and control they need to meet their business goals, or they can choose open-standard solutions that provide embedded network capabilities and robust security. Both solutions offer enterprise flexibility and can help organizations adapt to the changing IT landscape. The right solution can help enterprises meet the challenges of a complex modern IT landscape.
SD-WAN is designed to prioritize business-critical traffic and steer it to the fastest path. SD-WAN can improve employee productivity and staff morale by offering a highly reliable connection. Furthermore, it can reduce the latency problems and packet loss associated with Internet-based applications. SD-WAN solutions also have the advantage of allowing enterprises to migrate applications from direct connectivity to SaaS services.
Today, organizations are increasingly adopting cloud-based infrastructure and a distributed workforce. However, these changes are also exposing organizations to significant security risks. According to an IDC survey, 41% of respondents reported increased security incidents in 2017. Although many SD-WAN solutions have built-in security, basic firewall and VPN functions are insufficient. Organizations must also apply additional security measures to their SD-WAN connections after deployment.
