It starts a local server that behaves like Azure Storage, so you can dev against it like you would Azure.Microsoft Azure Cloud Services Part 5: Debug, Monitor & Scale - Simple TalkRun your application in Azure emulator and then find out its IP and Port by right-clicking. Azurite is an open source Azure Storage emulator that supports Windows and Linux. The only way to use DefaultAzureCredential is with token based auth and it only supports HTTPS.
Use Azure Storage Emulator On A Mac OS XWe’ll see how you can debug your application both locally and in the cloud, as well as take a look at what you’ll typically do when your application is running in production: monitoring and scaling. In this part we’re getting closer to deploying our Cloud Service to production. Mini-sized app so you can use more of your local storage for yourself.The previous articles covered the basics you need to understand and build your own Cloud Service. And Wii Emulator for Microsoft Windows, Linux, and Mac OS X (Intel-based). Alternatively, edit the value of AzureWebJobsStorage in local.settings.json under the projects root folder and under /workflow-designtime to a valid connection string for an Azure storage account. Make sure you have Azure Storage Emulator installed and running.![]() The other big differences are that the Emulator Express cannot use the IIS Web Server and each role is limited to just one instance.When running the Cloud Service from within Visual Studio a tray icon will appear for the Emulator and you’ll be able to visualize your roles and instances by opening the Compute Emulator.In addition to that you can also use a Storage Emulator which emulates an Azure Storage account on your local machine by using SQL Express or Local DB. The Full Emulator requires Visual Studio to be started as an administrator while the Emulator Express does not require this. The alternative is using a normal IIS Web Server which comes closer to how your application will be running when deployed to a Cloud Service.The second choice you can make is the type of emulator you want to run. Password protect a microsoft word for mac 2011 documentThe main reason why this is so hard is due to the fact that your application hasn’t really started yet, so most of the time there aren’t any detailed logs available to help you troubleshoot the issue.This is why IntelliTrace (which is part of Visual Studio 2013 Ultimate) can be an interesting feature to activate during the deployment of your Cloud Service. These issues can be hard to troubleshoot and are often related to files that are missing in the Service Package. IntellitraceAn issue you’ll probably run into at some point when deploying your Cloud Service is that the role instance is Cycling which means that the instance keeps restarting in a loop during the deployment. If you do choose to use a live account it should be a different storage account than the one you’re using in production. The reference wasn’t set to Copy Local = true in the reference’s properties.Note that enabling IntelliTrace will consume a lot of resources in your instances. For this deployment the Fabrikam.Todos.Helpers assembly was missing from the deployment. In case you’re doing a call to your database, you’ll see the full statement being executed for example.Figure 7 shows troubleshooting an issue with a missing assembly in the Service Package. You can then select one of the recorded exceptions and double click it to attach the debugger.The debugger will attach itself to the recording and using the IntelliTrace pane you’ll be able to navigate through every recorded event that can contain a lot of detailed information. This will download the “recording” and will allow you to analyse it locally in your Visual Studio.The IntellTrace Summary will be your first stop when troubleshooting issues with instances that have problems starting up. ![]() This is where we’ll move to a more automated way of scaling your Cloud Service.The dashboard allows you to configure Auto Scaling for your roles. This is the easiest but also the less automated way to scale your Cloud Service.Figure 13: Manually changing the number of instancesTypically you’ll want to scale when something happens: the site is very slow, it takes a long time before orders are being processed, etc. This is why scaling and managing of your Cloud Service becomes important once your application is running in production.In “ Part 1: Introduction” we’ve seen how easy it is to scale a role by just moving a slider up or down and hitting the Save button. It’s important that you keep it like this and that your application runs in the best circumstances. If you still need to test the behaviour with a production instance you can always swap the application to a staging slot and troubleshoot from there (to avoid any impact for your users).Your application is now running in the cloud without any issues. That’s why it’s best not to use the Remote Debugger in production. In both cases every time instances are added or removed there will be a pause of 20 minutes between operations to avoid instances from being added or removed all the time.Another metric that can be used is the CPU of your instances. When the number drops below 2000 messages the auto scale engine will start removing instances. As soon as we exceed (2000 * the number of machines) in a given storage queue more instances will be added to the Role until the maximum (8) is reached. The target number of messages in queue “commands-webrole” is 2000. Figure 14 shows a possible scenario where we want to have no less than 1 instance and no more than 8 instances in our Web Role.
