Azure 网站缩放

问题描述

我可以使用 Azure 管理库扩展 Azure Web 应用程序/api 应用程序吗?我基本上想实现 Web 应用程序的扩展和缩减以处理限制.因此，我需要通过 C# 代码扩展 Web 应用程序和 api 应用程序.任何指向任何适当的库/ReST API 的指针?

在下面提到的答案的帮助下，我了解了如何更新 APP 服务计划以扩展，但是，我无法为我的 APP 服务找到 webHostingPlanName.我尝试使用以下代码，托管计划总是为空.

 var regionName = "myregion";var 凭证 = GetCredentials();var websiteManagementClient = CloudContext.Clients.CreateWebSiteManagementClient(credentials);var webSpaces = websiteManagementClient.WebSpaces.List();var webSpace = webSpaces.FirstOrDefault(x => x.GeoRegion == regionName);如果(网络空间 == 空){throw new Exception(string.Format("No webspace for region {0} found", regionName));}var webHostingPlans = websiteManagementClient.WebHostingPlans.List(webSpace.Name);var webHostingPlan = webHostingPlans.FirstOrDefault();//这个总是空的，我知道这个区域有APP服务

解决方案

是的，我们可以使用 Microsoft.WindowsAzure.Management.Websites 库来扩展和缩减 Web 应用程序.使用方法 WebSiteManagementClient.WebHostingPlans.UpdateAsync(webspaceName, webHostingPlanName, webHostingPlanUpdateParameters) 来实现.

我做了一个演示来做到这一点.以下是我的详细步骤:

1.安装我们可以从

• 上传.将证书文件发送到 Azure 门户，然后获取指纹

3.使用代码生成 WebsiteManagementClient 对象

 public static X509Certificate2 GetCert(string thumbprint){X509Store certStore = new X509Store(StoreName.My, StoreLocation.CurrentUser);certStore.Open(OpenFlags.ReadOnly);X509Certificate2Collection certCollection = certStore.Certificates.Find(X509FindType.FindByThumbprint, thumbprint, false);if (certCollection.Count <= 0) 返回空值；X509Certificate2 证书 = certCollection[0];返回证书；}

var cert = GetCert(字符串指纹)var subscriptionId =您的订阅 ID"var webSiteManagementClient = new WebSiteManagementClient(new CertificateCloudCredentials(subscriptionId, cert));

4.构造WebHostingPlanUpdateParameters

var webHostingPlanUpdateParameters = new WebHostingPlanUpdateParameters{NumberOfWorkers = 1,//实例数SKU = SkuOptions.标准，WorkerSize = WorkerSizeOptions.Small};

5. 使用代码更新 WebHostingPlans

client.WebHostingPlans.UpdateAsync(webspaceName, webHostingPlanName, webHostingPlanUpdateParameters);

注意:如果您尝试在 Azure 上运行该项目.请参阅文档 在 Azure 网站应用程序中使用证书.添加一个名为 WEBSITE_LOAD_CERTIFICATES 的应用设置，并将其值设置为证书的指纹，将使您的 Web 应用程序可以访问它

Can I scale azure web apps/api apps using Azure Management libraries? I basically want to implement scaling up and down of web apps to handle throttling. Hence, I need to scale the web app and api apps via C# code. Any pointers to any apprpriate library/ ReST API?

With teh help of the answer mentioned below, I understand how to update the APP Service plan to scale out, however, I am not able to find webHostingPlanName for my APP Service. I tried with the below code, and hosting plan always comes out to be null.

        var regionName = "myregion";

        var credentials = GetCredentials();

        var websiteManagementClient = CloudContext.Clients.CreateWebSiteManagementClient(credentials);

        var webSpaces = websiteManagementClient.WebSpaces.List();
        var webSpace = webSpaces.FirstOrDefault(x => x.GeoRegion == regionName);
        if (webSpace == null)
        {
            throw new Exception(string.Format("No webspace for region {0} found", regionName));
        }

        var webHostingPlans = websiteManagementClient.WebHostingPlans.List(webSpace.Name);
        var webHostingPlan = webHostingPlans.FirstOrDefault();// this is null always, I know an APP service exists in this region

解决方案

Yes, We can use Microsoft.WindowsAzure.Management.Websites library to scale up and down of web apps.Using method WebSiteManagementClient.WebHostingPlans.UpdateAsync(webspaceName, webHostingPlanName, webHostingPlanUpdateParameters) to implement it.

I had done a demo to do this. The following are the my detail steps:

1.Install the Microsoft.WindowsAzure.Management.WebSites that we can get it from the link.

2.Create the WebsiteManagementClient object.

I used the cert to create the websitemagement client.

• Create a cert with makecert.exe that is under the VS folder after install the VS.

  makecert -sky exchange -r -n "CN=[CertificateName]" -pe -a sha1 -len 2048 -ss My "[CertificateName].cer
  

• Upload the. Cert file to Azure portal then get the thumbprint

3. Using the code to generate the WebsiteManagementClient object

          public static X509Certificate2 GetCert(string thumbprint)
    {

        X509Store certStore = new X509Store(StoreName.My, StoreLocation.CurrentUser);
        certStore.Open(OpenFlags.ReadOnly);
   X509Certificate2Collection certCollection = certStore.Certificates.Find(X509FindType.FindByThumbprint, thumbprint, false);
        if (certCollection.Count <= 0) return null;
        X509Certificate2 cert = certCollection[0];
        return cert;
    }

var cert = GetCert(string thumbprint) var subscriptionId ="Your subscriptionId"var webSiteManagementClient = new WebSiteManagementClient(new CertificateCloudCredentials(subscriptionId, cert));

4.Construct the WebHostingPlanUpdateParameters

var webHostingPlanUpdateParameters = new WebHostingPlanUpdateParameters
                {
                    NumberOfWorkers = 1, //the number of the instances
                    SKU = SkuOptions.Standard,
                    WorkerSize = WorkerSizeOptions.Small
                };

5.Update the WebHostingPlans with code

client.WebHostingPlans.UpdateAsync(webspaceName, webHostingPlanName, webHostingPlanUpdateParameters);
