This example of cloud computing system architecture diagram was created on base of the figure "Workflow to distribute workitems to pooled VMs" in the article "Azure Batch technical overview" from the Microsoft Azure website.
Figure 4 shows a you how to submit an application to a pool where it's distributed for processing. This uses the Batch API. ...
1. Upload input files (such as source data or images) required for a job to an Azure storage account. These files must be in the storage account so that the Batch service can access them. The Batch service loads them onto a TVM when the task runs.
2. Upload the dependent binary files to the storage account. The binary files include the program that is run by the task and the dependent assemblies. These files must also be accessed from storage and are loaded onto the TVM.
3. Create a pool of TVMs, specifying the size of the TVMs in the pool, the OS they run, and other properties. When a task runs, it is assigned a TVM from this pool.
4. Create a workitem. A job will be automatically created when you create a workitem. A workitem enables you to manage a job of tasks.
5. Add tasks to the job. Each task uses the program that you uploaded to process information from a file you uploaded.
6. Run the application and monitor the results of the output." [azure.microsoft.com/en-us/documentation/articles/batch-technical-overview/]
The diagram example "Workitems workflow diagram" was created using ConceptDraw PRO diagramming and vector drawing software extended with the Azure Architecture solution from the Computer and Networks area of ConceptDraw Solution Park.
