Use Cases for Azure NVAs

  • Distributed Application Protection: NVAs provide robust security measures between on-premises and cloud applications enabling a uniform security policy.
  • Optimizing Distributed Application Performance: It improves the performance of distributed applications by optimizing traffic flow and reducing latency leading to an improved user experience.
  • Safeguarding Data and Compliance: Secure sensitive data from malicious attacks by maintaining strong security policies on the WAF and also can create logs for compliance.
  • Optimizing Network Traffic for the Complex Architectures: These NVAs monitor and optimize traffic across complex network topologies to better allow the data flow and minimize bottlenecks.

Choosing the Right NVA for Your Needs

Selecting the most suitable Network Virtual Appliance (NVA) requires careful consideration of several factors to ensure it aligns with your specific needs. Here’s a breakdown of key aspects to evaluate:

  • Performance: Traffic Volume: Assess the typical volume of network traffic your NVA will handle. Choose an NVA with sufficient processing power and memory to avoid bottlenecks.
  • Security Features: Determine your security requirements. If advanced threat protection is crucial, prioritize NVAs offering intrusion detection/prevention, malware scanning, and deep packet inspection.
  • Compatibility: Infrastructure & Applications: Ensure the NVA is compatible with your existing infrastructure and applications. Verify if it integrates seamlessly with your current network management tools.

What is an Azure Network Virtual Appliance (NVA)?

An Azure Network Virtual Appliance (NVA) is a virtual appliance providing a wide range of network functionality similar to traditional physical networking appliances, in virtualized network environments in Azure Cloud. NVAs play a critical role in controlling and securing network traffic by routing traffic, firewalls, and balancing the load on this traffic....

Types of Network Virtual Appliances

Firewalls: Firewalls are security systems designed to monitor and control network traffic that moves between a network and the Internet. In Azure, NVAs can provide firewalls that safeguard investments in the cloud. IDS/IPS — Intrusion Detection and Prevention Systems: IDS/IPS solutions watch the network for suspicious behavior, and they look for anything that seems like an attack or a threat. While certain threats can be detected and alerted by IDS systems, an Intrusion Prevention System (IPS) may additionally, block malicious traffic. Load Balancers: A load balancer distributes incoming network or application traffic across servers in such a way that no single server is overworked. This improves reliability and performance. WAN Optimization Controllers: It achieves this by mitigating the data that may need to be sent across a wide-area network (WAN) and using caching algorithms to further improve the performance of applications....

Benefits of Using NVAs in Azure

Enhanced Security: NVAs include a range of security layers like deep packet inspection, traffic filtering, and more that give cyber security professionals a profound degree of assurance against cyber threats. Improved Network Performance: Despite a popular misconception that NVAs slow down network traffic, they necessarily improve network performance by optimizing traffic flow and distributing workloads to help applications execute correctly, as a whole. Scalability&Flexibility: NVAs are easily scalable: They can be scaled up or down depending on demand, making NVAs suitable for businesses of all sizes. It is flexible so that it can integrate with a number of Azure services and third-party solutions. Easy Network Management: Centralization of network management through NVAs allows to easy monitoring, configuration, and maintenance the network resources....

How NVAs Work in Azure?

Deployment Scenarios: You can deploy NVAs at various points in your network for multiple use cases, ranging from routing between subnets, or managing inbound and outbound traffic on the network edge. Integration with Azure Services: The Network Virtual Appliance (NVA) devices slot in seamlessly with other Azure services like Virtual Networks, Azure VPN Gateways, and Azure Firewalls to deliver an abundance of network functionality and security features. Traffic Routing and ControlNVAs control what traffic is permitted to move in and out of the device, and specify which specific virtual appliances traffic is directed through based on pre-defined policies and rules to optimally direct data flow....
