When reviewing network performance optimization in Azure, there are three main areas to zero in on.
First, get comfortable with traffic flow patterns. Understand tools like the Azure Network Watcher Traffic Analysis, which helps you visualize how traffic moves across regions and the Internet. This is going to be key for things like spotting bottlenecks and planning for a more efficient network deployment.
Topology in Azure Network Watcher provides an interactive, graphical visualization of your Azure virtual network infrastructure, displaying relationships, subnets, and connected resources (virtual machines, gateways, and load balancers).
Other things, focus on low-latency traffic direction. This is where Azure Traffic Manager comes into play. It routes users to the closest or fastest endpoint, which is crucial for keeping apps and websites up.
Finally, dive into modern content delivery networks, especially Azure Front Door. It’s designed for high-performance global delivery. So understand the different types that are available. Understand the different use cases as well as bandwidth considerations for each. You’ll see these as scenario questions on your exam.
