network watcher
got 4 components
-
- Connection Monitor - latency and network issues with IaaS devices over a PERIOD OF TIME
- Connection troubleshoot - latency and network issues with IaaS devices ONE-TIME
- IP Flow - latency and network issues at the VM LEVEL
- Network Performance Monitor - latency and network issues in hybrid, ON-PREM, across environments

hen an NSG is created, it automatically blocks TCP port 8080 between the virtual networks.
Solution: You configure a custom policy definition, and then you assign the policy to the subscription.
-
NSG 3rd rule is allow
Next rule evaluated should be AllowVNetInBound, allowing any traffic from the same vNET.

only owner can add device, device admin also CAN'T

The Logic App Contributor role lets you manage logic app, but not access to them. It provides access to view, edit, and update a logic app.
user role
= can do start, stop, terminate action on Ec2
User role only lets you connect, start, restart, and shutdown virtual machines in your Azure DevTest Labs.

internal Load balancer
-
if between web and app login, don't choose Applicaton gateway load balancer

stndard versus basic
-
Standard Load Balancer is secure by default and part of your virtual network. The virtual network is a private and isolated network.
Standard load balancers and standard public IP addresses are closed to inbound connections unless opened by Network Security Groups. NSGs are used to explicitly permit allowed traffic. If you don't have an NSG on a subnet or NIC of your virtual machine resource, traffic isn't allowed to reach this resource. To learn about NSGs and how to apply them to your scenario, see Network Security Groups.

Custom Script Extension
Downloads and executes scripts on Azure virtual machines. This extension is useful for post deployment configuration, software installation, or any other configuration or management tasks. Using a Custom Script Extension you can make sure that NGINX is installed once the VMs are deployed.

Desired State config
PowerShell DSC enables you to express the desired state of your systems using declarative language syntax instead of complex imperative scripts. You can use PowerShell DSC with AWS CloudFormation to bootstrap and configure servers and apps for your software platform on AWS.

little similar to cloudformation but not 100%, coz only apply to powershell

log
A network security group (NSG) enables you to filter inbound traffic to, and outbound traffic from, a virtual machine (VM). You can log network traffic that flows through an NSG with Network Watcher's NSG flow log capability.
Although you may be tempted to choose iLB1, diagnostic logs for a basic load balancer do not include the IP addresses of inbound connections. Flow logs do, and those get attached to the network security group.
