New generation technologies and rapid growth in the network system have created a high demand for dynamic IT infrastructure. As a result, enterprises are on the verge of moving towards more agile technologies, updating the technology market. 

Agility, security and hybrid infrastructure through WAN (Wide Area Network) will give users a poor user application experience. However, WAN plays a major role in reducing the time and covering the distance limitation in message transfer between two companies or enterprises. 

Data vulnerability and traffic might unpredictably be the biggest threats. Managed SD-WAN solutions are something that can address these issues. An example of SD-WAN is a 4G connection that brings all the businesses under the same secure connection. 

Software Defined Wide Area Network (SDWAN) is a Wide Area Network (WAN) that uses software-defined networking technologies using overlay tunnels and encrypted messages within the organization. Concerning performance, there isn’t an end-to-end in SD-WAN.

SD-WAN Architecture 

The following are the components of an SD-WAN:

  • SD-WAN EdgeSD is the physical or virtual function present
  • SD-WAN Gateway provides services that reduce traffic in cloud-based services
  • SD-WAN Controller makes use of IP packets that decide the application flow. All the service level agreements are met here.
  • SD-WAN Orchestration provides a central implementation by hosting and providing tools for all the cloud services.

Why is SD-WAN needed?

Here are a few reasons why SDWAN technology is considered intelligent for:

  • Application friendly

Consider a company with more than 1000 employees using more than 200 applications for each of its processes. SDWAN plays an important role in integrating these physically or virtually operated applications.

  • Security

VPN, remote access and various devices use the application, and the data must be in absolute sync to maintain the integration. SDWAN has many security features that can be customized according to the level of authority in every business. SDWAN also provides access to third-party applications securely.

  • Automation

Automation in SD-WAN helps derive policies and improve network traffic and efficiency decisions. A few examples are switching to the best network and handling failures, alerts and notifications.

  • Resilience and Optimisation

The downtime caused due to various issues is relatively reduced due to automatic switching and real-time features. Optimal data is also possible with the help of catch memory present to access the latest user data over and over. Amazon web services, Microsoft Azure, and Salesforce are some real-time examples.

  • Better user Experience and Management

This is possible with the highly available enterprise application and centralized cloud management services. Zero-touch and bandwidth with template-based options make it easier to manage.

  • Detailed Reporting

SDWAN uses an index to maintain the usage of the mapped network, traffic pattern monitoring, anomalies in the network and behavior of the system and hence always has a detailed data list and reporting system. This helps to maintain an apt experience with learning and training the system further.

Managed SD-WAN solutions to the user, is an addition to the existing system where WAN is replaced and enhanced with SDWAN security and performance every time. Here service level agreements are generally used, which provide users with entry-level services with a minimum guarantee. 

Infrastructure management and connectivity-based issues are solved in a cost-efficient manner and with more flexibility with the use of SD-WAN technology networks.
