Scaling Azure Websites
Can I scale azure web / api apps using Azure Management Libraries? Basically I want to implement scaling applications and throttling processing applications. Hence, I need to scale the web app and api apps through C # code. Any pointers to any suitable ReST library / API?
With the answer mentioned below, I understand how to update the APP service plan to scale down, however, I cannot find the webHostingPlanName for my APP service. I tried with the below code and the hosting plan is always 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

Yes, we can use the Microsoft.WindowsAzure.Management.Websites library to scale up and down web applications. Using a method WebSiteManagementClient.WebHostingPlans.UpdateAsync(webspaceName, webHostingPlanName, webHostingPlanUpdateParameters)
to implement it.
I made a demo for this. Below are my steps:
1.Install Microsoft.WindowsAzure.Management.WebSites so we can get it from ...
2. Create a WebsiteManagementClient object .
I used a certificate to create a websitemagement client.
-
Create a certificate using makecert.exe, which is under the VS folder after installing VS.
makecert -sky exchange -r -n "CN=[CertificateName]" -pe -a sha1 -len 2048 -ss My "[CertificateName].cer
- Download. Certify the file to the Azure portal, then get a fingerprint
3. Using Code to Create 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.Create the parameters WebHostingPlanUpdateParameters
var webHostingPlanUpdateParameters = new WebHostingPlanUpdateParameters
{
NumberOfWorkers = 1, //the number of the instances
SKU = SkuOptions.Standard,
WorkerSize = WorkerSizeOptions.Small
};
5.Remove WebHostingPlans with code
client.WebHostingPlans.UpdateAsync(webspaceName, webHostingPlanName, webHostingPlanUpdateParameters);
Note. If you try to run a project on Azure. Please refer to Using Certificates in Azure Websites Apps . Adding application settings named WEBSITE_LOAD_CERTIFICATES with its value set to the certificate thumbprint will make it available to your web application.
