{
"from": "gpt",
"value": "The required changes for this step have already been made for you in the [_Step3-CleanupOriginalPrimaryNodeType.json_](https://learn.microsoft.com/en-us/azure/service-fabric/<https:/github.com/microsoft/service-fabric-scripts-and-templates/tree/master/templates/nodetype-upgrade/Step3-CleanupOriginalPrimaryNodeType.json>) template file, and the following sections will explain these template changes in detail. If you prefer, you can skip the explanation and continue to [deploy the updated template](https://learn.microsoft.com/en-us/azure/service-fabric/<#deploy-the-finalized-template>) and complete the tutorial.\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#update-the-cluster-management-endpoint>)\n#### Update the cluster management endpoint\nUpdate the cluster `managementEndpoint` on the deployment template to reference the new IP (by updating _vmNodeType0Name_ with _vmNodeType1Name_).\n```\n \"managementEndpoint\": \"[concat('https://',reference(concat(variables('lbIPName'),'-',variables('vmNodeType1Name'))).dnsSettings.fqdn,':',variables('nt0fabricHttpGatewayPort'))]\",\n\n```\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#remove-the-original-node-type-reference>)\n#### Remove the original node type reference\nRemove the original node type reference from the Service Fabric resource in the deployment template:\n```\n\"name\": \"[variables('vmNodeType0Name')]\",\n\"applicationPorts\": {\n \"endPort\": \"[variables('nt0applicationEndPort')]\",\n \"startPort\": \"[variables('nt0applicationStartPort')]\"\n},\n\"clientConnectionEndpointPort\": \"[variables('nt0fabricTcpGatewayPort')]\",\n\"durabilityLevel\": \"Bronze\",\n\"ephemeralPorts\": {\n \"endPort\": \"[variables('nt0ephemeralEndPort')]\",\n \"startPort\": \"[variables('nt0ephemeralStartPort')]\"\n},\n\"httpGatewayEndpointPort\": \"[variables('nt0fabricHttpGatewayPort')]\",\n\"isPrimary\": true,\n\"reverseProxyEndpointPort\": \"[variables('nt0reverseProxyEndpointPort')]\",\n\"vmInstanceCount\": \"[parameters('nt0InstanceCount')]\"\n\n```\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#configure-health-policies-to-ignore-existing-errors>)\n#### Configure health policies to ignore existing errors\nOnly for Silver and higher durability clusters, update the cluster resource in the template and configure health policies to ignore `fabric:/System` application health by adding _applicationDeltaHealthPolicies_ under cluster resource properties as given below. The below policy will ignore existing errors but not allow new health errors.\n```\n\"upgradeDescription\":\n{\n \"forceRestart\": false,\n \"upgradeReplicaSetCheckTimeout\": \"10675199.02:48:05.4775807\",\n \"healthCheckWaitDuration\": \"00:05:00\",\n \"healthCheckStableDuration\": \"00:05:00\",\n \"healthCheckRetryTimeout\": \"00:45:00\",\n \"upgradeTimeout\": \"12:00:00\",\n \"upgradeDomainTimeout\": \"02:00:00\",\n \"healthPolicy\": {\n \"maxPercentUnhealthyNodes\": 100,\n \"maxPercentUnhealthyApplications\": 100\n },\n \"deltaHealthPolicy\":\n {\n \"maxPercentDeltaUnhealthyNodes\": 0,\n \"maxPercentUpgradeDomainDeltaUnhealthyNodes\": 0,\n \"maxPercentDeltaUnhealthyApplications\": 0,\n \"applicationDeltaHealthPolicies\":\n {\n \"fabric:/System\":\n {\n \"defaultServiceTypeDeltaHealthPolicy\":\n {\n \"maxPercentDeltaUnhealthyServices\": 0\n }\n }\n }\n }\n}\n\n```\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#remove-supporting-resources-for-the-original-node-type>)\n#### Remove supporting resources for the original node type\nRemove all other resources related to the original node type from the ARM template and the parameters file. Delete the following:\n```\n \"vmImagePublisher\": {\n \"value\": \"MicrosoftWindowsServer\"\n },\n \"vmImageOffer\": {\n \"value\": \"WindowsServer\"\n },\n \"vmImageSku\": {\n \"value\": \"2019-Datacenter\"\n },\n \"vmImageVersion\": {\n \"value\": \"latest\"\n },\n\n```\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#deploy-the-finalized-template>)\n#### Deploy the finalized template\nFinally, deploy the modified Azure Resource Manager template.\n```\n# Deploy the updated template file\n$templateFilePath = \"C:\\Step3-CleanupOriginalPrimaryNodeType\"\nNew-AzResourceGroupDeployment `\n -ResourceGroupName $resourceGroupName `\n -TemplateFile $templateFilePath `\n -TemplateParameterFile $parameterFilePath `\n -CertificateThumbprint $thumb `\n -CertificateUrlValue $certUrlValue `\n -SourceVaultValue $sourceVaultValue `\n -Verbose\n\n```\n\nNote\nThis step will take a while, usually up to two hours.\nThe upgrade will change settings to the _InfrastructureService_ ; therefore, a node restart is needed. In this case, _forceRestart_ is ignored. The parameter `upgradeReplicaSetCheckTimeout` specifies the maximum time that Service Fabric waits for a partition to be in a safe state, if not already in a safe state. Once safety checks pass for all partitions on a node, Service Fabric proceeds with the upgrade on that node. The value for the parameter `upgradeTimeout` can be reduced to 6 hours, but for maximal safety 12 hours should be used.\nOnce the deployment has completed, verify in Azure portal that the Service Fabric resource Status is _Ready_. Verify you can reach the new Service Fabric Explorer endpoint, the **Cluster Health State** is _OK_ , and any deployed applications function properly.\nNow, you've vertically scaled a cluster primary node type!\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#next-steps>)"

Services are not statically tied to a particular machine or address.\nA Service Fabric application is generally composed of many different services, where each service performs a specialized task. These services may communicate with each other to form a complete function, such as rendering different parts of a web application. There are also client applications that connect to and communicate with services. This document discusses how to set up communication with and between your services in Service Fabric.\n[Check this page for a training video that also discusses service communication:](https://learn.microsoft.com/en-us/azure/service-fabric/</en-us/shows/building-microservices-applications-on-azure-service-fabric/service-network-communication>)\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#bring-your-own-protocol>)"

When your service is opened by Service Fabric, that's your service's opportunity to set up an endpoint for incoming requests, using whatever protocol or communication stack you want. Your service will listen on a normal **IP:port** address using any addressing scheme, such as a URI. Multiple service instances or replicas may share a host process, in which case they will either need to use different ports or use a port-sharing mechanism, such as the http.sys kernel driver in Windows. In either case, each service instance or replica in a host process must be uniquely addressable.\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#service-discovery-and-resolution>)"

},
{
"from": "gpt",
"value": "In a distributed system, services may move from one machine to another over time. This can happen for various reasons, including resource balancing, upgrades, failovers, or scale-out. This means service endpoint addresses change as the service moves to nodes with different IP addresses, and may open on different ports if the service uses a dynamically selected port.\n\nService Fabric provides a discovery and resolution service called the Naming Service. The Naming Service maintains a table that maps named service instances to the endpoint addresses they listen on. All named service instances in Service Fabric have unique names represented as URIs, for example, `\"fabric:/MyApplication/MyService\"`. The name of the service does not change over the lifetime of the service, it's only the endpoint addresses that can change when services move. This is analogous to websites that have constant URLs but where the IP address may change. And similar to DNS on the web, which resolves website URLs to IP addresses, Service Fabric has a registrar that maps service names to their endpoint address.\n\nResolving and connecting to services involves the following steps run in a loop:\n * **Resolve** : Get the endpoint that a service has published from the Naming Service.\n * **Connect** : Connect to the service over whatever protocol it uses on that endpoint.\n * **Retry** : A connection attempt may fail for any number of reasons, for example if the service has moved since the last time the endpoint address was resolved. In that case, the preceding resolve and connect steps need to be retried, and this cycle is repeated until the connection succeeds.\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#connecting-to-other-services>)"

This is exactly what the DNS service does. It enables you to map DNS names to a service name and hence resolve endpoint IP addresses.\nAs shown in the following diagram, the DNS service, running in the Service Fabric cluster, maps DNS names to service names which are then resolved by the Naming Service to return the endpoint addresses to connect to. The DNS name for the service is provided at the time of creation.\n\nFor more details on how to use the DNS service see [DNS service in Azure Service Fabric](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-dnsservice>) article.\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#reverse-proxy-service>)"

"value": "A Service Fabric cluster in Azure is placed behind an Azure Load Balancer. All external traffic to the cluster must pass through the load balancer. The load balancer will automatically forward traffic inbound on a given port to a random _node_ that has the same port open. The Azure Load Balancer only knows about ports open on the _nodes_ , it does not know about ports open by individual _services_.\n\nFor example, in order to accept external traffic on port **80** , the following things must be configured:\n 1. Write a service that listens on port 80. Configure port 80 in the service's ServiceManifest.xml and open a listener in the service, for example, a self-hosted web server.\nXML Copy\n```\n<Resources>\n <Endpoints>\n <Endpoint Name=\"WebEndpoint\" Protocol=\"http\" Port=\"80\" />\n </Endpoints>\n</Resources>\n\n```\n\nC# Copy\n```\n class HttpCommunicationListener : ICommunicationListener\n {\n ...\n public Task<string> OpenAsync(CancellationToken cancellationToken)\n {\n EndpointResourceDescription endpoint =\n serviceContext.CodePackageActivationContext.GetEndpoint(\"WebEndpoint\");\n string uriPrefix = $\"{endpoint.Protocol}://+:{endpoint.Port}/myapp/\";\n this.httpListener = new HttpListener();\n this.httpListener.Prefixes.Add(uriPrefix);\n this.httpListener.Start();\n string publishUri = uriPrefix.Replace(\"+\", FabricRuntime.GetNodeContext().IPAddressOrFQDN);\n return Task.FromResult(publishUri);\n }\n ...\n }\n class WebService : StatelessService\n {\n ...\n protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()\n {\n return new[] { new ServiceInstanceListener(context => new HttpCommunicationListener(context))};\n }\n ...\n }\n\n```\n\nJava Copy\n```\n class HttpCommunicationlistener implements CommunicationListener {\n ...\n @Override\n public CompletableFuture<String> openAsync(CancellationToken arg0) {\n EndpointResourceDescription endpoint =\n this.serviceContext.getCodePackageActivationContext().getEndpoint(\"WebEndpoint\");\n try {\n HttpServer server = com.sun.net.httpserver.HttpServer.create(new InetSocketAddress(endpoint.getPort()), 0);\n server.start();\n String publishUri = String.format(\"http://%s:%d/\",\n this.serviceContext.getNodeContext().getIpAddressOrFQDN(), endpoint.getPort());\n return CompletableFuture.completedFuture(publishUri);\n } catch (IOException e) {\n throw new RuntimeException(e);\n }\n }\n ...\n }\n class WebService extends StatelessService {\n ...\n @Override\n protected List<ServiceInstanceListener> createServiceInstanceListeners() {\n <ServiceInstanceListener> listeners = new ArrayList<ServiceInstanceListener>();\n listeners.add(new ServiceInstanceListener((context) -> new HttpCommunicationlistener(context)));\n return listeners;\n }\n ...\n }\n\n```\n\n 2. Create a Service Fabric Cluster in Azure and specify port **80** as a custom endpoint port for the node type that will host the service. If you have more than one node type, you can set up a _placement constraint_ on the service to ensure it only runs on the node type that has the custom endpoint port opened.\n\n 3. Once the cluster has been created, configure the Azure Load Balancer in the cluster's Resource Group to forward traffic on port 80. When creating a cluster through the Azure portal, this is set up automatically for each custom endpoint port that was configured.\n\n 4. The Azure Load Balancer uses a probe to determine whether or not to send traffic to a particular node. The probe periodically checks an endpoint on each node to determine whether or not the node is responding. If the probe fails to receive a response after a configured number of times, the load balancer stops sending traffic to that node. When creating a cluster through the Azure portal, a probe is automatically set up for each custom endpoint port that was configured.\n\n\nIt's important to remember that the Azure Load Balancer and the probe only know about the _nodes_ , not the _services_ running on the nodes. The Azure Load Balancer will always send traffic to nodes that respond to the probe, so care must be taken to ensure services are available on the nodes that are able to respond to the probe.\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#reliable-services-built-in-communication-api-options>)"

},
{
"from": "gpt",
"value": "The Reliable Services framework ships with several pre-built communication options. The decision about which one will work best for you depends on the choice of the programming model, the communication framework, and the programming language that your services are written in.\n * **No specific protocol:** If you don't have a particular choice of communication framework, but you want to get something up and running quickly, then the ideal option for you is [service remoting](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-reliable-services-communication-remoting>), which allows strongly-typed remote procedure calls for Reliable Services and Reliable Actors. This is the easiest and fastest way to get started with service communication. Service remoting handles resolution of service addresses, connection, retry, and error handling. This is available for both C# and Java applications.\n * **HTTP** : For language-agnostic communication, HTTP provides an industry-standard choice with tools and HTTP servers available in many different languages, all supported by Service Fabric. Services can use any HTTP stack available, including [ASP.NET Web API](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-reliable-services-communication-aspnetcore>) for C# applications. Clients written in C# can leverage the `ICommunicationClient` and `ServicePartitionClient` classes, whereas for Java, use the `CommunicationClient` and `FabricServicePartitionClient` classes, [for service resolution, HTTP connections, and retry loops](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-reliable-services-communication>).\n * **WCF** : If you have existing code that uses WCF as your communication framework, then you can use the `WcfCommunicationListener` for the server side and `WcfCommunicationClient` and `ServicePartitionClient` classes for the client. This however is only available for C# applications on Windows based clusters. For more details, see this article about [WCF-based implementation of the communication stack](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-reliable-services-communication-wcf>).\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#using-custom-protocols-and-other-communication-frameworks>)"

An example is gaming, where a console needs to make a direct connection to a cloud virtual machine, which is doing game physics processing.

"value": "Isolated Image Builds enables defense-in-depth by limiting network access of your build VM to just your subscription. Isolated Image Builds also provides you with more transparency by allowing your inspection of the processing done by AIB to customize/validate your VM image. Further, Isolated Image Builds eases viewing of live build logs. Specifically:\n 1. **Compute Isolation:** Isolated Image Builds performs major portion of image building processing in ACI resources in your subscription instead of on AIB's shared platform resources. ACI provides hypervisor isolation for each container group to ensure containers run in isolation without sharing a kernel.\n 2. **Network Isolation:** Isolated Image Builds removes all direct network WinRM/ssh communication between your build VM and backend components of the AIB service.\n * If you're provisioning an AIB template without your own subnet for build VM, then a Public IP Address resource is no more provisioned in your staging resource group at image build time.\n * If you're provisioning an AIB template with an existing subnet for build VM, then a Private Link based communication channel is no more setup between your build VM and AIB's backend platform resources. Instead, the communication channel is set up between the ACI and the build VM resources - both of which reside in the staging resource group in your subscription.\n * Starting API version 2024-02-01, you can specify a second subnet for deploying the ACI in addition to the subnet for build VM. If specified, AIB deploys ACI on this subnet and there's no need for AIB to set up the Private Link based communication channel between the ACI and the build VM. For more information about the second subnet, see the section [here](https://learn.microsoft.com/en-us/azure/virtual-machines/<security-isolated-image-builds-image-builder#bring-your-own-build-vm-subnet-and-bring-your-own-aci-subnet>).\n 3. **Transparency:** AIB is built on HashiCorp [Packer](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/www.packer.io/>). Isolated Image Builds executes Packer in the ACI in your subscription, which allows you to inspect the ACI resource and its containers. Similarly, having the entire network communication pipeline in your subscription allows you to inspect all the network resources, their settings, and their allowances.\n 4. **Better viewing of live logs:** AIB writes customization logs to a storage account in the staging resource group in your subscription. Isolated Image Builds provides with another way to follow the same logs directly in the Azure portal, which can be done by navigating to AIB's container in the ACI resource.\n\nNote\nTo access the live logs during the image build or the customization and validation log files after the build is complete, please refer to the [troubleshooting guide](https://learn.microsoft.com/en-us/azure/virtual-machines/<linux/image-builder-troubleshoot#accessing-live-logs-during-image-build>).\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#network-topologies>)"

"from": "gpt",
"value": "Isolated Image Builds is a platform level change and doesn't affect AIB's interfaces. So, your existing Image Template and Trigger resources continue to function and there's no change in the way you deploy new resources of these types. You need to create new templates or update existing templates if you want to use [the network topology allowing bringing your own ACI subnet](https://learn.microsoft.com/en-us/azure/virtual-machines/<security-isolated-image-builds-image-builder#bring-your-own-build-vm-subnet-and-bring-your-own-aci-subnet>).\nYour image builds are automatically migrated to Isolated Image Builds and you need to take no action to opt in. Also, customization logs continue to be available in the storage account.\nDepending on the network topology specified in the Image Template, you might observe a few new resources temporarily appear in the staging resource group (for example, ACI, Virtual Network, Network Security Group, and Private Endpoint) while some other resources no longer appear (for example, Public IP Address). As earlier, these temporary resources exist only during the build and AIB deletes them thereafter.\nImportant\nMake sure your subscription is registered for `Microsoft.ContainerInstance provider`:\n * Azure CLI: `az provider register -n Microsoft.ContainerInstance`\n * PowerShell: `Register-AzResourceProvider -ProviderNamespace Microsoft.ContainerInstance`\n\nAfter successfully registering your subscription, make sure there are no Azure Policies in your subscription that deny deployment of ACI resoures. Policies allowing only a restricted set of resource types not including ACI would cause Isolated Image Builds to fail.\nEnsure that your subscription also has a sufficient [quota of resources](https://learn.microsoft.com/en-us/azure/virtual-machines/<../container-instances/container-instances-resource-and-quota-limits>) required for deployment of ACI resources.\nImportant\nDepending on the network topology specified in the Image Template, AIB may need to deploy temporary networking related resources in the staging resource group in your subscription. Ensure that no Azure Policies deny the deployment of such resources (Virtual Network with Subnets, Network Security Group, Private endpoint) in the resource group.\nIf you have Azure Policies applying DDoS protection plans to any newly created Virtual Network, either relax the Policy for the resource group or ensure that the Template Managed Identity has permissions to join the plan. Alternatively, you can use the network topology that does not require deployment of a new Virtual Network by AIB.\nImportant\nMake sure you follow all [best practices](https://learn.microsoft.com/en-us/azure/virtual-machines/<image-builder-best-practices>) while using AIB.\nNote\nAIB is in the process of rolling this change out to all locations and customers. Some of these details (especially around deployment of new Networking related resources) might change as the process is fine-tuned based on service telemetry and feedback.

[Next step](https://learn.microsoft.com/en-us/azure/virtual-machines/<#next-step>)\n\nShow 2 more\n**Applies to:** ✔️ Uniform scale set\nAzure Virtual Machine Scale Sets has two modes:\n * **Uniform Orchestration** : In this mode, virtual machine scale sets use a virtual machine (VM) profile or a template to scale up to the capacity you want. Although there's some ability to manage or customize individual VM instances, Uniform Orchestration uses identical VM instances. These instances are exposed through the virtual machine scale set's VM APIs and aren't compatible with the API commands that are standard for Azure infrastructure as a service (IaaS) VMs. Because the scale set performs all the actual VM operations, reservations are associated to the virtual machine scale set directly. After the scale set is associated to the reservation, all the subsequent VM allocations are done against the reservation.\n * **Flexible Orchestration** : In this mode, you get more flexibility to manage the individual virtual machine scale set VM instances. They can use the standard Azure IaaS VM APIs instead of by using the scale set interface. To use reservations with Flexible Orchestration mode, define both the virtual machine scale set property and the capacity reservation property on each VM.\n\nTo learn more about these modes, see [Virtual Machine Scale Sets orchestration modes](https://learn.microsoft.com/en-us/azure/virtual-machines/<../virtual-machine-scale-sets/virtual-machine-scale-sets-orchestration-modes>).\nThis content applies to the Uniform Orchestration mode. For Flexible Orchestration mode, see [Associate a virtual machine scale set with Flexible Orchestration to a capacity reservation group](https://learn.microsoft.com/en-us/azure/virtual-machines/<capacity-reservation-associate-virtual-machine-scale-set-flex>).\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#limitations-of-scale-sets-in-uniform-orchestration>)"

"from": "gpt",
"value": "* For virtual machine scale sets in Uniform Orchestration to be compatible with capacity reservation, the `singlePlacementGroup` property must be set to `False`.\n * The **Static Fixed Spreading** availability option for multizone uniform scale sets isn't supported with capacity reservation. This option requires the use of five fault domains. However, the reservations only support up to three fault domains for general purpose sizes. The approach we recommend is to use the **Max Spreading** option that spreads VMs across as many fault domains as possible within each zone. If needed, configure a custom fault domain configuration of three or less.\n\nThere are some other restrictions when you use capacity reservations. For the complete list, see the [overview of capacity reservations](https://learn.microsoft.com/en-us/azure/virtual-machines/<capacity-reservation-overview>).\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#associate-a-new-virtual-machine-scale-set-to-a-capacity-reservation-group>)"

The template uses declarative syntax. In declarative syntax, you describe your intended deployment without writing the sequence of programming commands to create the deployment.\nARM templates let you deploy groups of related resources. In a single template, you can create capacity reservation group and capacity reservations. You can deploy templates through the Azure portal, the Azure CLI, or Azure PowerShell, or from continuous integration/continuous delivery (CI/CD) pipelines.\nTo associate a Virtual Machine Scale Set with a Capacity Reservation Group, see the following ARM template.

{
"from": "gpt",
"value": "You can create virtual machine scale sets regionally or in one or more availability zones to help protect them from datacenter-level failure. To learn more about multizonal virtual machine scale sets, see [Virtual machine scale sets that use availability zones](https://learn.microsoft.com/en-us/azure/virtual-machines/<../virtual-machine-scale-sets/virtual-machine-scale-sets-use-availability-zones>).\nImportant\nThe location (region and availability zones) of the virtual machine scale set and the capacity reservation group must match for the association to succeed. For a regional scale set, the region must match between the scale set and the capacity reservation group. For a zonal scale set, both the regions and the zones must match between the scale set and the capacity reservation group.\nWhen a scale set is spread across multiple zones, it always attempts to deploy evenly across the included availability zones. Because of that even deployment, a capacity reservation group should always have the same quantity of reserved VMs in each zone. As an illustration of why this even deployment is important, consider the following example.\nIn this example, each zone has a different quantity reserved. Let's say that the virtual machine scale set scales out to 75 instances. Because a scale set always attempts to deploy evenly across zones, the VM distribution should look like this example:\nExpand table\nZone | Quantity reserved | Number of scale set VMs in each zone | Unused quantity reserved | Overallocated\n---|---|---|---|---\n1 | 40 | 25 | 15 | 0\n2 | 20 | 25 | 0 | 5\n3 | 15 | 25 | 0 | 10\nIn this case, the scale set incurs extra cost for 15 unused instances in Zone 1. The scale-out is also relying on 5 VMs in Zone 2 and 10 VMs in Zone 3 that aren't protected by capacity reservation. If each zone had 25 capacity instances reserved, then all 75 VMs would be protected by capacity reservation and the deployment wouldn't incur any extra cost for unused instances.\nBecause the reservations can be overallocated, the scale set can continue to scale normally beyond the limits of the reservation. The only difference is that the VMs allocated above the quantity reserved aren't covered by capacity reservation service-level agreement. To learn more, see [Overallocate capacity reservation](https://learn.microsoft.com/en-us/azure/virtual-machines/<capacity-reservation-overallocate>).\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#next-step>)"

These virtual machines offer up to 96 vCPU and 192 GiB of RAM. These VM sizes can reduce cost when not running memory intensive applications.\nDlsv5-series virtual machines don't have any temporary storage thus lowering the price of entry. You can attach Standard SSD, Standard HDD, and Premium SSD disk types. You can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines. See pricing for disks.\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/sizes/general-purpose/<#host-specifications>)"

Burst speeds can be maintained for up to 30 minutes at a time.\n * Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare 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.\n * Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.\n * Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.\n * To learn how to get the best storage performance for your VMs, see [Virtual machine and disk performance](https://learn.microsoft.com/en-us/azure/virtual-machines/sizes/general-purpose/disks-performance>).\n\nNetwork interface info for each size\nExpand table\nSize Name | Max NICs (Qty.) | Max Network Bandwidth (Mb/s)\n---|---|---\nStandard_D2ls_v5 | 2 | 12500\nStandard_D4ls_v5 | 2 | 12500\nStandard_D8ls_v5 | 4 | 12500\nStandard_D16ls_v5 | 8 | 12500\nStandard_D32ls_v5 | 8 | 16000\nStandard_D48ls_v5 | 8 | 24000\nStandard_D64ls_v5 | 8 | 30000\nStandard_D96ls_v5 | 8 | 35000\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/sizes/general-purpose/<#networking-resources>)\n#### Networking resources\n * [Virtual networks and virtual machines in Azure](https://learn.microsoft.com/en-us/azure/virtual-machines/sizes/general-purpose/</en-us/azure/virtual-network/network-overview>)\n * [Virtual machine network bandwidth](https://learn.microsoft.com/en-us/azure/virtual-machines/sizes/general-purpose/</en-us/azure/virtual-network/virtual-machine-network-throughput>)\n\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/sizes/general-purpose/<#table-definitions-1>)\n#### Table definitions\n * Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations.

You can use it to manage and configure your virtual machines. This information includes the SKU, storage, network configurations, and upcoming maintenance events. For a complete list of the data available, see the [Endpoint Categories Summary](https://learn.microsoft.com/en-us/azure/virtual-machines/<#endpoint-categories>).\nIMDS is available for running instances of virtual machines (VMs) and scale set instances. All endpoints support VMs created and managed by using [Azure Resource Manager](https://learn.microsoft.com/en-us/azure/virtual-machines/</en-us/rest/api/resources/>). Only the Attested category and Network portion of the Instance category support VMs created by using the classic deployment model. The Attested endpoint does so only to a limited extent.\nIMDS is a REST API that's available at a well-known, non-routable IP address (`169.254.169.254`). You can only access it from within the VM. Communication between the VM and IMDS never leaves the host. Have your HTTP clients bypass web proxies within the VM when querying IMDS.\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#usage>)"

For more examples, see [Azure Instance Metadata Samples](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/github.com/microsoft/azureimds>).\nHere's sample code to retrieve all metadata for an instance. To access a specific data source, see [Endpoint Categories](https://learn.microsoft.com/en-us/azure/virtual-machines/<#endpoint-categories>) for an overview of all available features.\n**Request**\nImportant\nThis example bypasses proxies. You **must** bypass proxies when querying IMDS. See [Proxies](https://learn.microsoft.com/en-us/azure/virtual-machines/<#proxies>) for additional information.\nNote\nIMDS requests must be sent using VM's primary NIC and primary IP, and DHCP must be enabled.\n * [Windows](https://learn.microsoft.com/en-us/azure/virtual-machines/<#tabpanel_1_windows>)\n * [Linux](https://learn.microsoft.com/en-us/azure/virtual-machines/<#tabpanel_1_linux>)\n\n```\nInvoke-RestMethod -Headers @{\"Metadata\"=\"true\"} -Method GET -NoProxy -Uri \"http://169.254.169.254/metadata/instance?api-version=2021-02-01\" | ConvertTo-Json -Depth 64\n\n```\n\n`-NoProxy` requires PowerShell V6 or greater. See our [samples repository](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/github.com/microsoft/azureimds>) for examples with older PowerShell versions.\n```\ncurl -s -H Metadata:true --noproxy \"*\" \"http://169.254.169.254/metadata/instance?api-version=2021-02-01\" | jq\n\n```\n\nThe `jq` utility is available in many cases, but not all. If the `jq` utility is missing, use `| python -m json.tool` instead.\n**Response**\nNote\nThe response is a JSON string. The following example response is pretty-printed for readability.\n * [Windows](https://learn.microsoft.com/en-us/azure/virtual-machines/<#tabpanel_1_windows>)\n *

"value": "The Instance Metadata Service is only accessible from within a running virtual machine instance on a non-routable IP address. VMs can only interact with their own metadata/functionality. The API is HTTP only and never leaves the host.\nIn order to ensure that requests are directly intended for IMDS and prevent unintended or unwanted redirection of requests, requests:\n * **Must** contain the header `Metadata: true`\n * Must **not** contain an `X-Forwarded-For` header\n\nAny request that doesn't meet **both** of these requirements are rejected by the service.\nImportant\nIMDS is **not** a channel for sensitive data. The API is unauthenticated and open to all processes on the VM. Information exposed through this service should be considered as shared information to all applications running inside the VM.\nIf it isn't necessary for every process on the VM to access IMDS endpoint, you can set local firewall rules to limit the access. For example, if only a known system service needs to access instance metadata service, you can set a firewall rule on IMDS endpoint, only allowing the specific process(es) to access, or denying access for the rest of the processes.\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#proxies>)"
