1 00:00:00,940 --> 00:00:05,070 Network Watcher is, I like to describe it as a Swiss Army knife. 2 00:00:05,070 --> 00:00:08,000 It's a collection of tools that help you visualize and 3 00:00:08,000 --> 00:00:10,310 troubleshoot hybrid cloud networking. 4 00:00:10,310 --> 00:00:14,630 Now predominantly, these tools are focused on Azure virtual machines. 5 00:00:14,630 --> 00:00:18,150 We can, in the next hop module that you see on this screenshot, we 6 00:00:18,150 --> 00:00:22,690 can model, we can dial up a VM in the interface and then model a 7 00:00:22,690 --> 00:00:27,170 connection to some destination IP address. That IP can be within 8 00:00:27,170 --> 00:00:29,160 Azure, it can be outside of Azure, 9 00:00:29,160 --> 00:00:33,050 it can be a public or private IP address, and the tool will 10 00:00:33,050 --> 00:00:36,620 tell you whether you're using Azure system routing or 11 00:00:36,620 --> 00:00:39,080 user‑defined routing and that kind of stuff. 12 00:00:39,080 --> 00:00:44,440 So you'll find that each Network Watcher tool has a defined use case behind it. 13 00:00:44,440 --> 00:00:47,480 I don't want you to fall into the trap of thinking that you're going to 14 00:00:47,480 --> 00:00:52,530 have to juggle all these simultaneous SSH and RDP connections when 15 00:00:52,530 --> 00:00:54,630 you're troubleshooting network connectivity, 16 00:00:54,630 --> 00:01:00,000 let's say, between Azure VMs or on‑prem VMs and Azure VMs. 17 00:01:00,000 --> 00:01:04,260 Network Watcher can be awfully helpful to serve as an 18 00:01:04,260 --> 00:01:07,840 intermediary to help you visualize some of these connection 19 00:01:07,840 --> 00:01:10,270 paths. And not just for troubleshooting, 20 00:01:10,270 --> 00:01:13,820 but I also submit for performance tuning and optimization and even 21 00:01:13,820 --> 00:01:17,640 security, you'll find these Network Watcher tools are useful. 22 00:01:17,640 --> 00:01:21,240 I have an entire course in the Pluralsight library on Network 23 00:01:21,240 --> 00:01:28,000 Watcher. It's a little bit on the old side, honestly, but it may still be worthwhile you looking at.
