I need to limit a download speed of one self hosted IR in Azure to an on premise server to prevent the network to get clogged up.
What are my options here? Is it possible to set this is ADF directly or in the IR or do I have to set this in the network?
According to this MSDN thread it's not possible to throttle bandwidth natively in Azure Data Factory.
However, if you are using an Azure Data Factory Self-Hosted Integration Runtime you could probably throttle the bandwidth at the VM level. For example, for Windows VMs you could try a QoS Group Policy to throttle the network for all applications or just the Integration Runtime executable.
Was there any loss of packets or impact on data - we recently just deployed ADF IR on-prem we have to set QOS to 50Mpbs across a 200Mpbs network.

I am trying to accomplish one task which is below.
What I am doing it.
All my users are on Premises.
Application is hosted on Azure VM IaaS.
Question =>
Azure cloud application talk with Internet and download huge packages and share with client which is on- Primes. So I am trying to understand the Risk and latency matrix between on-Prime users and Azure cloud application.
If any one has done some sort of thing and encounter latency issues and what will be possible fixes for that?
Note=> I can't Migrate user to Azure cloud as of now.
To encounter latency issues, please try the following:
To reduce the latency between on premises client and azure cloud application make use of Azure HPC cache.
Azure HPC Cache reduces latency for applications where data may be tethered to existing infrastructure because of dataset sizes and operational scale.
Azure HPC caches active data automatically that is present in both on-premises and in Azure.
You can make use of Accelerated networking where communication will be done more fast.
Try eliminating network congestion.
Try reducing number of network nodes needed to traverse from one stage to another.
Make use of Azure ExpressRoute and Azure Analysis Services to reduce Network latency.
Azure ExpressRoute creates a private connection between on-premises sources and the Azure.
Azure Analysis Services avoids the need for an on-premises data gateway and generally eliminates network latency.

When executing "Azure Data Factory Pipeline".
Is there a way to monitor internal and external traffic transmission status?
In the metric or warning of 'Datafactory',
I couldn't see the corresponding part of the measurable term item,
so I asked.
If you are using Self-Hosted Integration Runtime in the ADF pipelines then you can monitor the network traffic on the IR VM whenever you execute the pipeline
The scenario is as follows:
In company premise, there is a network that consists few machines.
The company has an Azure subscription.
Requirement:
To monitor the company's Network/Machines via Azure
If the company resource goes beyond a threshold limit then trigger alerts. Example, network bandwidth consumption, machine CPU/Memory usage, etc.
When such alerts occur then spin up new virtual machines or VM scale sets in Azure to handle the load.
The purpose is if the machines in on-prem goes above threshold limit then automatically provision VMs in Azure, as there are only few on-prem machines.
Please guide how to implement these use cases?
your question is a little confusing. You mention machines on premises and using Azure to monitor them. You can monitor on premises VMs using Azure but then you mention provisioning new Azure VMs via Scale Sets.
I'm not 100% where your workload is but assuming it is in Azure then if you are using VM Scale Sets it's very easy to scale in and out based on resource utilisation.
This can be configured as described here: https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-autoscale-portal
Out of the box, Azure Advisor includes Cost recommendations for the resource type of Virtual Machines, based on resource utilization.
If I look at them under our subscription they have the following information:
Is there any way to get similar advisory for the Virtual Machine Scale Set resource type? Is there any included out of the box?
Or if I want to get average resource consumption, of let's say CPU percentage of all or individual Virtual Machine instances inside of a Virtual Machine Scale set, to be able to aid in the decision if the SKU of the Virtual Machine Scale Set is appropriate, I need to make a query for this inside of Monitor Logs or similar?
Could one create their own custom made advisories (inside of Azure Advisor, if not - anywhere else?), to get this functionaltiy in place (if it isn't already provided)?
Thanks!

As per the Azure Advisor documentation, Advisor provides recommendations for the following resource types:
Application Gateway, App Services, availability sets, Azure Cache, Azure Data Factory, Azure Database for MySQL, Azure Database for PostgreSQL, Azure Database for MariaDB, Azure ExpressRoute, Azure Cosmos DB, Azure public IP addresses, Azure Synapse Analytics, SQL servers, storage accounts, Traffic Manager profiles, and Virtual machines.
Although Azure Advisor also includes your recommendations from Azure Security Center which may include recommendations for additional resource types, this list does not cover cost recommendations for VMSS as of today, AFAIK.
I need to make a query for this inside of Monitor Logs or similar?
To monitor your Virtual machine Scale sets, you can leverage Azure Monitor. The performance views in the VM Insights feature are powered using log analytics queries, offering “Top N”, aggregate, and list views to quickly find outliers or issues in your scale set based on guest level metrics for CPU, available memory, bytes sent and received, and logical disk space used.
You can also deploy the Azure Monitor Application Insights Agent on Azure virtual machine scale sets to enable monitoring for your .NET or Java based web applications and get all the benefits of using Application Insights without modifying your code.
Could one create their own custom made advisories (inside of Azure Advisor, if not - anywhere else?), to get this functionaltiy in place (if it isn't already provided)?
Nope, that is not doable as of today. Azure Advisor is a managed offering that analyzes your resource configuration and usage telemetry and then recommends solutions that can help you optimize your Azure resources. Feel free to share your feedback and ideas here for the Advisor team to evaluate and prioritize.
I'm currently looking into a high-availability approach for a file server within Azure in which I will need to be deploying VMs for. The data on the file server will be constantly changing. From what I read so far, I will need at least 2 VMs and grouping them together into a shared availability set along with creating a cloud service. Although this will address the application and server aspect, what about the storage and the data on them?
I understand that I can't attach a single disk to multiple VMs so I'm a bit lost on how to proceed with this. Any thoughts or ideas on how to move forward with this?
In short, I have a VM with direct data disk attached to it that I'm looking to provide high-availability in the event that the VM goes offline; either through an outage, host patching, hardware maintenance, etc...
Have a look into Azure Blob Storage - don't worry about disks etc, just let the Azure fabric handle the data redundancy and scalability for you!
