azure-worker-roles

From what I understand both run small repeatable tasks in the cloud. What reasons and in what situations might I want to choose one over the other? Some basic information: WebJobs are good for lightweight work items that don't need any customization of the environment they run in and don't consume very much resources. They are also really good for tasks that only need to be run periodically, scheduled, or triggered. They are cheap and easy to setup/run. They run in the context of your Website which means you get the same environment that your Website runs in, and any resources they use are

We have an Azure worker role that exposes a RESTful WCF service (using System.ServiceModel.Web) through a ServiceHost. The performance is irreproachable on massive traffic, but it seems like the response time is significantly higher (more than five seconds) on the first request when the role has been idle for some time. Does anyone know what might cause this? David Makogon The default AppPool timeout is 20 minutes. Might you be running into this? If so, you can add something like this to a startup script to change the timeout: %windir%\system32\inetsrv\appcmd set config -section

After installation of windows update on 10th February 2016, the azure roles are not starting in emulator (Full/Express).

Can I have a Web Role and a Worker role run on the same instance, or do I have to obtain 2 separate hosting instances and pay twice the amount I would otherwise? I have a WCF Web API that I want to host on Azure. I also have a Worker Role that listens to a Queue in Azure Storage. Every time a message is added to the Queue, it will obtain that and run a small task depending on the message. I was wondering if I can just run these two on the same instance or not. David Makogon "Worker Role" and "Web Role" are just simple templates for "Windows Server 2008 with IIS running" and "Windows Server

I'm currently porting a WCF Service Project over to an Azure Role. Until now the library containing the service also hosted a Quartz.Net JobFactory for some lightweight background processing (perdiodically cleaning up stale email confirmation tokens). Do I have to move that code into a seperate worker role? BitKFu No you don't have to setup a separate worker role. You simply have to start a background thread in your OnStart() Method of your Web Role. Give that thread a Timer object that executes your method after the given timespan. Due to this you can avoid a new worker role. class

I am trying to use Windows Azure Caching to store sessions in a MVC4 application. I build a application following steps from Link but when i try to make object of DataCache using below code line. DataCache cache = new DataCache("default"); Errors occurs: Microsoft.WindowsAzure.ServiceRuntime.dll not found or version mismatched, I updated my Windows Azure Emulator version to 2.0.0 and install WindowsAzure.Caching package version 2.0.0.0 using NuGet package installer.
