WAN Service is a cloud-based approach to WAN deployment and management. It leverages software-defined networking technologies to create a more flexible and cost-efficient network infrastructure. In this model, network resources are virtualized and delivered as a subscription-based service.
Here’s a breakdown of the core components and principles of WAN Service:
Virtualization of Network Resources
WAN service leverages virtualization to abstract and centralize network resources, allowing more efficient resource utilization and simplified network management.
Software-Defined Networking (SDN)
SDN is the technology that underpins WAN service. It separates the network’s control plane from the data plane, enabling centralized management and dynamic configuration. SD-WAN managed services effectively and securely route network traffic across on-premises and cloud solutions. The technology helps optimize traffic flow across dispersed hybrid systems.
Cloud Connectivity
WAN service often leverages cloud-based connections, allowing enterprises to connect to multiple cloud services seamlessly.
Automation and Orchestration
WAN service platforms provide automation and orchestration capabilities, simplifying the management of complex network configurations
BENEFITS OF WAN SERVICE FOR ENTERPRISES
WAN-as-a-Service offers advantages that can significantly benefit enterprises. Here are ten benefits of WAN-as-a-Service:
1. COST SAVINGS
One of the most prominent advantages of WAN service is cost savings. By shifting to a subscription-based model, enterprises can avoid large upfront capital expenses associated with traditional MPLS networks. A pay-as-you-go approach allows for more predictable and manageable expenses.
2. IMPROVED SCALABILITY
WAN Service offers the flexibility to scale network resources up or down as needed. It is particularly valuable for enterprises that experience fluctuations in demand or are expanding geographically. Scalability ensures that the network can grow with the business without significant infrastructure overhauls.
3. FASTER DEPLOYMENT
Traditional WAN implementations can be time-consuming, often taking weeks or even months to deploy. In contrast, WAN service can be set up quicker, often within days. The rapid deployment capability is crucial for businesses that need to respond to changing circumstances or set up new branch offices rapidly.
4. ENHANCED PERFORMANCE
With the ability to optimize traffic routes and prioritize critical applications, WAN-as-a-Service can improve network performance. It ensures mission-critical applications run smoothly and user experiences remain consistent, even during peak usage.
5. NETWORK RESILIENCE
WAN service platforms have built-in redundancy and failover mechanisms. These features mean that in the event of a network disruption, traffic can seamlessly reroute to maintain connectivity, minimizing downtime and business disruption.
6. SUPPORT FOR CLOUD INTEGRATION
As more enterprises embrace cloud services, WAN service simplifies cloud integration. It offers direct connections to popular cloud providers, which can reduce latency and improve the performance of cloud-hosted applications.
Purpose of a WAN
Wide-area networks (WANs) are the backbone of enterprise today. With the digitization of resources, companies use WANs to do the following:
• Communicate using voice and video.
• Share resources between employees and customers.
• Access data storage and remotely back up data.
• Connect to applications running in the cloud.
• Run and host internal applications.
WAN technology innovations help organizations access information in a secure, fast, and reliable way. WANs are important for business productivity and continuity.
