zWAN – SD-WAN USE CASE

SD-WAN Solutions for SaaS-Based Applications

Use Case: Organizations increasingly rely on cloud-based services and Software-as-a-Service (SaaS) applications requiring fast and secure connectivity to platforms like AWS, Microsoft Azure, and Google Cloud.

As organizations increasingly adopt Software-as-a-Service (SaaS) applications to enhance operational efficiency, ensuring reliable, secure, and high-performing network connectivity becomes critical. However, traditional WAN architectures struggle to meet modern cloud demands, leading to latency, congestion, and security vulnerabilities that degrade SaaS application performance.

Common Challenges with SaaS Connectivity:

Latency and Performance Issues

Traditional WANs often backhaul SaaS traffic through centralized data centers, causing delays and congestion that result in unresponsive collaboration tools, slow file transfers, and poor VoIP/video call quality.

Bandwidth Constraints & Network Congestion

The rising demand for SaaS applications increases bandwidth usage, causing network congestion during peak hours, while the lack of traffic prioritization forces business-critical apps to compete with non-essential traffic, leading to performance slowdowns.

Security Risks with Direct Internet Access

SaaS applications require constant internet access, which can expose corporate networks to cyber threats, compliance violations, and data breaches, while traditional firewalls struggle to inspect SaaS-bound traffic, leaving gaps in security enforcement.

Complex Network & Traffic Management

Managing multiple network connections, routing policies, and security protocols across locations is challenging for IT teams, often resulting in inconsistent SaaS performance for remote workers and branch offices, which impacts overall efficiency.

How AmZetta’s zWAN Addresses These Challenges:

Quality of Service (QoS)

In traditional network configurations, all network traffic is created equally. This means that a major conference call using a VoIP or video conferencing application would get the same priority as a standard user streaming videos while they work. With zWAN’s QoS, business-critical and SaaS based applications can be prioritized over non-critical traffic and ensuring that higher priority SaaS applications will receive the necessary bandwidth in the event of network congestion

SaaS Breakout for Direct Cloud Access

In legacy environments, traffic to SaaS applications are routed back through the main corporate data centers, causing additional hops and exposing trusted SaaS traffic to additional security measures. With zWAN’s, SaaS Breakout allows trusted SaaS applications to connect directly to cloud and SaaS providers, bypassing unnecessary data center routing and additional security inspections. This reduces latency, improves speed, eases overall network congestion, and improves user experience for real-time and business-critical applications SaaS communication.

Deep Packet Inspection (DPI) for Advanced Security

DPI scans and categorizes network traffic, identifies threats, blocks unauthorized access and enforces security policies. DPI is configured at the edge Gateway Router and will identify trusted SaaS based traffic and allow that traffic to route straight to the internet and avoiding additional security policies and backhauling.

Multi-Path WAN

zWAN’s SD-WAN solution utilizes multiple WAN paths ensuring connectivity for all communications over less expensive network paths. For SaaS applications this allows administrators to configure the utilization of multiple paths to make sure that business critical and real time applications are always available.

Simplified Centralized Management

The Director provides a single-pane-of-glass for monitoring, optimizing, and managing SaaS application traffic across all locations. Real-time analytics enable IT teams to detect network issues, enforce policies, and ensure optimal SaaS performance.

Ideal Use Cases:

Enterprises with Distributed Workforces

zWAN enables employees seamless collaboration across various locations to access cloud-based software tools with minimal latency, enhancing productivity.

Organizations Adopting Hybrid Cloud Strategies

Flexible resource management support for hybrid deployments, zWAN allows businesses to balance workloads between on-premises infrastructure and cloud services efficiently.

Industries with High Data Security Requirements

Finance, healthcare, and government rely on DPI, encrypted tunnels, and access controls to protect sensitive SaaS data.

Work-From-Home (WFH) Employees Connecting via VPN

zWAN supports secure remote access to SaaS and corporate applications via encrypted VPN tunnels, ensuring protected communication.

Branch Office Traffic Routed Through Data Center for Security

Businesses requiring centralized security enforcement can route SaaS traffic through corporate data centers, ensuring policy consistency and regulatory compliance.

Conclusion:

AmZetta’s zWAN SD-WAN solution provides a powerful, secure, and scalable way to enhance SaaS application performance, optimize traffic, and simplify network management. By leveraging Dynamic Path Selection, SaaS Breakout, Deep Packet Inspection, Quality of Service (QoS), Traffic Shaping, and Intelligent Routing, zWAN ensures uninterrupted, high-speed, and secure access to cloud applications.
