What are the limits of Azure cloud services?
Azure Cloud Services limits 1 Each Azure Cloud Service with web or worker roles can have two deployments, one for production and one for staging. This limit refers to the number of distinct roles, that is, configuration. This limit doesn't refer to the number of instances per role, that is, scaling.
How many Azure resources can I create as required?
This ability helps reduce costs and efficiently create Azure resources as required. Scale sets support up to 1,000 VM instances. If you create and upload your own custom VM images, the limit is 600 VM instances. For the best performance with production workloads, use Azure Managed Disks. Scale sets are built from virtual machines.
How many virtual machines can be deployed into a cloud service?
Each cloud service can contain up to 50 virtual machines.
Is there a limit to number of VMs?
Max 1280 VMs per Cluster. Max 100 VMs per Host. If the number of Hosts exceeds 8 in a cluster, the limit of VMs per host is 40.
What is the maximum number of application VMs that you can host on one of your new servers?
Maximum are 384 VMs, have a look at the links above will give you good insight into it.
How many virtual machines can be run on a single host machine?
You may be able to fit as many as 100 VMs on a single host, or as few as two.

What is the maximum number of virtual CPUs you can use with an FT protected virtual machine?
8The maximum number of vCPUs aggregated across all fault tolerant VMs on a host. The default value is 8. There is no FT vCPU per host maximum, you can use larger numbers if the workload performs well. You can disable checking by setting the value to 0 .
How many VMs can I run with 4 cores?
So with 4 cores, i should not run more than 4 VMs.
Can you run multiple virtual machines at once?
Yes you can run multiple virtual machines at once. They can appear as separate windowed applications or take over the full screen.
How many VM can I run on Windows 10?
The limits for Windows 10 are similar or even higher. So, as you can see, in theory it is possible to run 1024 VMs at the same time depending on your hardware. And this is a point, it is hard to find Windows 10 client machine with hardware allowing to run 1024 VMs at the same time. 1.
What is Azure Cloud Services?
Azure Cloud Services (extended support) is a new Azure Resource Manager based deployment model for the Azure Cloud Services product . With this change, Azure Cloud Services running on the Azure Service Manager based deployment model have been renamed as Cloud Services (classic) and all new deployments should use Cloud Services (extended support).
What is ACU in Azure?
We have created the concept of the Azure Compute Unit (ACU) to provide a way of comparing compute (CPU) performance across Azure SKUs and to identify which SKU is most likely to satisfy your performance needs. ACU is currently standardized on a Small (Standard_A1) VM being 100 and all other SKUs then represent approximately how much faster that SKU can run a standard benchmark.
Can you use PowerShell to get a list of sizes?
You can use PowerShell or the REST API to get a list of sizes. The REST API is documented here. The following code is a PowerShell command that will list all the sizes available for Cloud Services.
Network interfaces
A network interface (NIC) is the interconnection between a virtual machine and a virtual network. A virtual machine must have at least one NIC. A virtual machine can have more than one NIC, depending on the size of the VM you create. To learn about the number of NICs each virtual machine size supports, see VM sizes.
IP addresses
You can assign these types of IP addresses to a network interface in Azure:
Virtual network and subnets
A subnet is a range of IP addresses in the virtual network. You can divide a virtual network into multiple subnets for organization and security. Each NIC in a VM is connected to one subnet in one virtual network. NICs connected to subnets (same or different) within a virtual network can communicate with each other without any extra configuration.
Network security groups
A network security group (NSG) contains a list of Access Control List (ACL) rules that allow or deny network traffic to subnets, NICs, or both. NSGs can be associated with either subnets or individual NICs connected to a subnet. When an NSG is associated with a subnet, the ACL rules apply to all the VMs in that subnet.
Load balancers
Azure Load Balancer delivers high availability and network performance to your applications. A load balancer can be configured to balance incoming Internet traffic to VMs or balance traffic between VMs in a VNet.
Virtual machines
Virtual machines can be created in the same virtual network and they can connect to each other using private IP addresses. Virtual machines can connect if they're in different subnets. They connect without the need to configure a gateway or use public IP addresses. To put VMs into a virtual network, you create the virtual network.
Virtual network NAT
Virtual Network NAT (network address translation) simplifies outbound-only Internet connectivity for virtual networks. When configured on a subnet, all outbound connectivity uses your specified static public IP addresses. Outbound connectivity is possible without load balancer or public IP addresses directly attached to virtual machines.
Why use virtual machine scale sets?
To provide redundancy and improved performance, applications are typically distributed across multiple instances. Customers may access your application through a load balancer that distributes requests to one of the application instances.
Differences between virtual machines and scale sets
Scale sets are built from virtual machines. With scale sets, the management and automation layers are provided to run and scale your applications. You could instead manually create and manage individual VMs, or integrate existing tools to build a similar level of automation.
How to monitor your scale sets
Use Azure Monitor for VMs, which has a simple onboarding process and will automate the collection of important CPU, memory, disk, and network performance counters from the VMs in your scale set. It also includes extra monitoring capabilities and pre-defined visualizations that help you focus on the availability and performance of your scale sets.
Data residency
In Azure, the feature to enable storing customer data in a single region is currently only available in the Southeast Asia Region (Singapore) of the Asia Pacific Geo and Brazil South (Sao Paulo State) Region of Brazil Geo. Customer data is stored in Geo for all other regions. See Trust Center for more information.

Performance Considerations
Size Tables
- The following tables show the sizes and the capacities they provide. 1. Storage capacity is shown in units of GiB or 1024^3 bytes. When comparing disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 GB 2. Disk throughput is measured in input/output operations per s…

These 8 and 16 core VMs are built on the Intel Haswell E5-2667 V3 processor technology featuring DDR4 memory and local SSD-based storage. In addition to the substant...
Configure Sizes For Cloud Services
- You can specify the Virtual Machine size of a role instance as part of the service model described by the service definition file. The size of the role determines the number of CPU cores, the memory capacity, and the local file system size that is allocated to a running instance. Choose the role size based on your application's resource requirement. Here is an example for setting the ro…
Changing The Size of An Existing Role
- As the nature of your workload changes or new VM sizes become available, you may want to change the size of your role. To do so, you must change the VM size in your service definition file (as shown above), repackage your Cloud Service, and deploy it.
