Mainframes and punch cards were the first to be used for batch processing, leading to the discovery of Microsoft Azure Batch Services: Compute Management Platform. It is still used in business, engineering, science, and other fields that require a large number of automated tasks, such as processing accounts and payroll, calculating portfolio risks, designing new products, rendering animated films, testing software, finding energy, etc. forecasting the weather and discovering new cures for diseases. Previously, only a few people had access to the computing power needed in these circumstances.
Azure Batch is a cloud computing service provided by Microsoft Azure. It enables large-scale parallel and high-performance computing (HPC) workloads by dynamically provisioning and managing clusters of virtual machines (VMs). Azure Batch allows users to schedule and execute computational tasks across multiple VMs, distributing the workload and maximizing efficiency. It is commonly used for tasks like simulations, rendering, data processing, and other computationally intensive workloads that require significant processing power.
Use Azure Batch to run large parallel and high-performance computing (HPC) batch jobs in Azure. Azure Batch generates and manages a pool of compute nodes (VMs), installs applications, and schedules jobs to run on the nodes. There is no software to install, manage, or extend for clusters or task schedulers. Instead, you configure, manage, and monitor your operations using Batch APIs and tools, command-line scripts, or the Azure website.
Developers can use Batch as a platform service to build SaaS services or client applications that require large-scale execution. For example, you can use Batch to create a service that runs a Monte Carlo risk simulation for a financial services organization or a service that processes many photos.
Azure Batch Supports multiple features, some of which are listed below:
Select the operating system and development tools needed to perform extensive tasks in Batch. Batch provides unified job management and schedule regardless of whether you are using Windows Server or Linux compute nodes but also allows you to take advantage of the unique features of each environment. Use your current Windows code, including Microsoft.NET, to perform large-scale computing operations in Azure with Windows. To run your computing operations on Linux, choose from popular distributions like CentOS, Ubuntu, and SUSE Linux Enterprise Server, or leverage Docker containers to lift and move your applications. Batch provides SDKs and supports various programming technologies such as Python and Java.
A batch runs applications on workstations and clusters. To scale, it’s easy to run cloud files and scripts. Batch creates a queue for the work you want to do and then runs your programs. Describe the data that must be transferred to the cloud for processing, how the data should be scattered, what parameters to use for each operation, and the command to start the process. Think of it as an assembly line with many applications. You can use a batch to transfer data between stages and to manage execution as a whole.
You use a workstation, maybe a small cluster, or wait in a queue to run jobs. What if you could access 16 or even 100,000 crores whenever you wanted them and only pay for what you used? You can do so using Batch. Avoid waiting, which can limit your creativity. What would you be able to achieve in Azure that you can’t do today?
Batch is built on an extensive job scheduling engine accessible to you as a managed service. Use the scheduler in your app to submit tasks. Batch can also be used with cluster task schedulers or behind the scenes in software as a service (SaaS). You don’t need to create your work queue, dispatcher, or monitor. Batch provides this as a service.
When you’re ready to run a job, Batch starts a pool of compute virtual machines for you, installs applications and work data, runs jobs with as many jobs as you have, detects problems, moves work to a queue, and shrinks the pool. Once the job is done. You regulate scope to meet deadlines, manage expenses, and run at the right scale for your application.
Batch processing jobs on demand, not on a set schedule, allows your clients to run jobs in the cloud when needed. Control who has access to Batch and how many resources they can use, as well as verify that criteria such as encryption are met. Rich monitoring lets you see what’s going on and uncover problems. You can monitor usage with a detailed report.
Follow these instructions to create a sample Batch account for testing purposes. You must have a Batch account to create pools and jobs. You can also connect a Batch account to an Azure storage account. A storage account is not required for this quick start but is useful for deploying applications and storing input and output data for most real-world tasks.
Azure Batch is a non-visual tool with no graphical user interface. After activating the Azure Batch component in Azure, you can start creating compute pools.
Once we have the compute pool and nodes in place, we can assign work to them. The work will be organized into tasks and assignments:
After submitting the jobs, Azure Batch dynamically assigns the work to different nodes. Each node can take over one or more tasks (depending on the VM’s number of cores). After all, tasks are completed, the task is marked as complete, and the compute nodes are ready to start the next task.
Azure Batch requires the use of an application or service manager to set up pools, assign jobs, and monitor if necessary. This service manager can be a portal interface, but we recommend using the available Python or R tools. In practice, you will use this Python (or R) script to create pools, tasks, and jobs.
The parallel package in R is a fantastic tool that allows you to delegate tasks to Azure Batch by executing each loop. The R-script within the for each loop is executed directly on the Azure Batch nodes. And the results are immediately batched and sent to the R user. The Azure Batch library in Python is just as powerful but works differently. This module makes it easy to use Python to create clusters and add jobs and tasks. However, it is up to the user to put the findings together.
A typical Batch scenario involves scaling internally parallel work, such as image rendering for 3D scenes, across a group of compute nodes. This pool can serve as your “render farm,” supplying tens, hundreds, or even thousands of cores to your rendering project. The diagram below illustrates the steps of a typical Batch workflow using a client application or hosted service that uses Batch for parallel workloads.

A. Azure Batch is a cloud computing service by Microsoft Azure that enables parallel processing and execution of large-scale computational workloads across multiple virtual machines. On the other hand, Control-M is an enterprise workload automation solution by BMC Software. It helps schedule, manage, and monitor various types of workloads, including batch processing, data pipelines, and job scheduling across hybrid and multi-cloud environments. While both serve workload management purposes, they differ in their focus, features, and underlying infrastructure.
A. Azure Batch is used for executing large-scale and high-performance computing (HPC) workloads. It provides the ability to distribute computational tasks across multiple virtual machines (VMs), enabling efficient parallel processing. Azure Batch is commonly employed for tasks like simulations, rendering, data processing, and scientific computations.
