What is Azure Networking?
In the vast expanse of Microsoft’s cloud computing platform, Azure, networking plays a crucial role in connecting and securing virtual machines, applications, and data. Azure Networking Fundamentals is the foundation upon which your cloud infrastructure is built.
Types of Networks in Azure
Azure offers three main types of networks: Virtual Networks (VNets), ExpressRoute Circuits, and Load Balancer. Each has its unique characteristics and use cases.
- Virtual Networks (VNets): These are software-defined networks that can span multiple regions and availability zones. VNets provide isolation between virtual machines and allow for IP address management, subnetting, and routing configuration.
- ExpressRoute Circuits: These are dedicated connections to Microsoft’s network over a private WAN link or the internet. ExpressRoute provides high-bandwidth, low-latency connectivity for large-scale enterprise applications.
- Load Balancer: This is a cloud-based load balancer that distributes incoming traffic across multiple virtual machines or instances. Load Balancer provides scalability, reliability, and performance enhancements.
Azure Network Security Groups (NSGs)
Azure NSGs are network security controls that filter inbound and outbound traffic based on source IP address, destination IP address, protocol, and port number. NSGs provide an additional layer of security for your virtual machines and applications.
Network Watcher in Azure
Network Watcher is a monitoring tool that provides real-time insights into network performance, packet capture, and flow logs. This allows administrators to troubleshoot network issues, detect potential security threats, and optimize network configuration.
Conclusion
In conclusion, Azure Networking Fundamentals provide the building blocks for your cloud infrastructure. Understanding the different types of networks, NSGs, and Network Watcher is crucial for securing and optimizing your virtual machines and applications in Azure.
