I have a virtual machine on Azure and I was wondering if there is a bandwidth limit for it.
By bandwidth limit I mean, a limit like 15GB of outbound and inbound data transfer.
I tried checking some forums about this but could not find a clear answer.
Yes, as your VM will be on shared infrastructure, there are bandwidth limits for your VM. And the bandwidth is metered on egress (outbound) only and not on the ingress (inbound).
Further the bandwidth depends on your VM Size. The below link gives the network bandwidth limit of Dav4 and Dasv4-series
https://learn.microsoft.com/en-us/azure/virtual-machines/dav4-dasv4-series
For more information on Virtual Machine network bandwidth,

Hope this helps

So I'm looking online at load balancers at Oracle Cloud etc. and their pricing is very confusing.
Oracle Cloud charges $0.0113/load balancer instance and $0.0001/1mbps traffic per hour.
They have a free tier, but for this example, let's pretend the free tier services and bandwidth ($10TB free/month) doesn't exist.
Does traffic that goes through the load balancer also add to the total bandwidth you use per month? Like cloud egress in general that costs $0.0085/GB? Or do you just pay the fee for the traffic that goes through the load balancer itself?
Microsoft Azure charges $0.005/GB of data "Data processed" with their load balancer.
If you used a compute server on their platform but put it behind a load balancer and disconnect it from the internet, are you still paying the $0.0875/GB of Internet Egress fees, or only the load balancer transfer fees of $0.005/GB?
What if you hosted something on another platform where egress didn't cost anything? Would you have to pay for internet egress, balancer egress, neither or both?
Same questions with Google Cloud. It costs about $0.0074/GB of data processed with the load balancer. Do you also have to pay egress fees (like $0.085/GB data transferred) or just $0.0074? Or both?
#nikolay pricing for LoadBalancer in GCP depend on the region where that LoadBalancer is located, i could not find the numbers you provided on our doc but generally speaking this is what you have to pay when you use LoadBalancers
First 5 forwarding rules at a fixed price
Each additional Forwarding rule at a fixed price per additional rule
Ingress (Incoming data) processed by the LB per GB
Egress (outgoing data from the LoadBalancer back to the caller) is charged at the normal rates
This docs explain it all
https://cloud.google.com/vpc/network-pricing#lb
https://cloud.google.com/vpc/network-pricing#all-networking-pricing
In Google Cloud Platform, Internet Egress and Load Balancing costs are calculated separately.
Load Balancer is billed based on the amount of Ingress data processed (Ingress itself is free) and number of forwarding rules.
So in your example, if your load balancer is processing incoming data, you are paying $0.0074/GB;
If you are responding to those packets, then you are also being billed Egress fee for the appropriate tier.
You can find more information in the documentation and estimate the cost yourself using the calculator.
We have a VPN Gateway in Azure with sku VpnGw1, so it should be able to handle 650 Mb/s.
We have one S2S connection and we've enabled P2S connectivity.
I would like to monitor the VPN Gateway so I know when we're getting close to the 650 Mb/s.
I assume that the 650 Mb/s is the bandwith consumed by both P2S and S2S. Or?
I've been looking at the metrics available but don't really understand what they tell me.
I've found these metrics that should be of intrest: Tunnel Bandwidth, Gateway S2S Bandwidth and Gateway P2S Bandwidth.
I've seen this site but I don't think it really explains the differences enough:
https://learn.microsoft.com/en-us/azure/vpn-gateway/monitor-vpn-gateway
These are the values I get when I look at the three metrics. It doesn't make sense to me.
Can someone explain to me?
Azure VPN Gateway with sku VpnGw1 has Throughput Benchmark 650 Mb/s.
P2S and S2S both consume 650 Mb/s bandwidth of Azure VPN Gateway.
Throughput Benchmark is metric calculated by Azure. It is obtained by running iperf3 between VNets in the same region, with minimum duration of 120 seconds and up to 32 flows.
Metrics that are available in Azure Monitor for monitoring Azure VPN gateways have different display names:
AverageBandwidth -> Gateway S2S Bandwidth
P2SBandwidth -> Gateway P2S Bandwidth
TunnelAverageBandwidth -> Tunnel Bandwidth
https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/azure-monitor/essentials/metrics-supported.md
You can check real bandwidth of Azure VPN Gateway by running Iperf test from your location.
https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-validate-throughput-to-vnet#run-iperf-iperf3exe
Or by using Azure Throughput Analyzer Tool

You can check latency from your location to Azure VPN Gateway by using link below

there is a VM in azure and running an IIS.
I have parsed all IIS logfiles and the whole outgoing traffic over last 7 days is about 2GB. The graphic show me traffic in amount 5-10 GB a day within the last seven days.
What is going on here?
Are there other known azure services increasing network traffic by default?
I guess I should sniff my machine to see if there are other services increasing my outgoing traffic.
There were "Diagnostics settings" enabled within my virtual machine. After disabling this, my traffic is going back to the regular amount.
I have been working on the Azure monitoring side for a while. I need your inputs for one of my requirement.
We have lot of IaaS VM’s both SQL and Non-SQL provisioned in our subscriptions. We are paying non-trivial amount for these VM’s. I am trying to come up w/ solution to identify low usage machines and during what times( night, early morning etc) the usage is very low. With this, I can take an action by either shut down VM’s during low usage period or reduce VM size.
For this, I am trying couple of options like Azure Advisor, Azure metrics for CPU usage, Network I/O, Disk Read/Write parameters. But considering only these might not help. Because, your network I/O might be having load balancer requests which cannot be considered.
So I need to come up w/ actual IIS requests went in during the given period.
Can you recommend on how to identify low usage VM’s? It would be a great help.
Can you recommend on how to identify low usage VM’s?
Generally, we will based on CPU usage to identify low usage VM.
Network traffic in or out of one application might be having load balancer requests, but network traffic in or out of this VM will not have load balancer, we also can use this to identify low usage VM.
So I need to come up w/ actual IIS requests went in during the given
period.
We can use OMS to monitor IIS request of each VMs in Azure, please follow this article to configure OMS.
like this:
Also we can config zabbix on one Azure VM and use that to monitor all VMs.
Is there any limit to send/receive an API response service from windows Azure Virtual Machine?
As far as I know, there isn't any limit to send/receive an API response from Azure VM. The VM create in Azure, it works as a server same as a on-premises server.
About the Azure VMs limits, refer to the link.
The Azure VM's performance according to different VM size.
No, I think there isn't any limit as such. VMs are billed on capacity and no of hours run.
No limit, but you do need to pay for bandwidth after a certain point. Check here: https://azure.microsoft.com/en-us/pricing/details/bandwidth/.
The first 5 Gigabytes per month of outbound traffic are free.
After that you have to start paying something. Your VM will usually cost way more than the bandwidth (license, VM size, storage).
