Configure compute for a batch deployment

Configuring compute for a batch deployment is an essential step in designing and implementing a data science solution on Azure. Batch processing allows you to run large-scale, compute-intensive tasks and jobs in parallel, making it suitable for scenarios such as data pre-processing, model training, and large-scale data analysis. In this article, we will explore different options available for configuring compute for a batch deployment on Azure.

1. Azure Batch service:

Azure Batch service is a cloud-based job scheduling service that allows you to run parallel and high-performance computing (HPC) applications efficiently. It provides a distributed execution environment for your batch workloads, allowing you to scale up or scale out based on your requirements. To configure compute using Azure Batch service, follow these steps:

1. Create an Azure Batch account: Start by creating an Azure Batch account in the Azure portal. This account will serve as the management and configuration interface for your Batch service.
2. Create a pool: Within the Batch account, create a pool that represents the set of virtual machines on which your tasks will run. Specify the VM size, the number of VM instances, and the operating system for the pool.
3. Configure auto-scale settings (optional): If your workloads vary in size and require dynamic scaling, you can configure auto-scale settings for your Azure Batch pool. Auto-scale settings enable the pool to automatically adjust the number of compute nodes based on workload demands.
4. Submit jobs and tasks: Once the pool is set up, you can submit jobs and tasks to the Azure Batch service. Each job consists of one or more parallel tasks that will be executed on the compute nodes in the pool.

2. Azure Machine Learning compute:

Azure Machine Learning provides a managed compute infrastructure for running training and inference workloads. With Azure Machine Learning compute, you can easily scale up or scale out your compute resources based on your data science requirements. To configure compute using Azure Machine Learning, follow these steps:

1. Create a compute target: Start by creating a compute target within your Azure Machine Learning workspace. This can be a cluster of virtual machines or an Azure Kubernetes Service (AKS) cluster.
2. Specify the compute configuration: For each compute target, define the desired compute configuration. This includes specifying the VM size, the number of instances, and any additional environment requirements.
3. Use compute targets in training scripts: In your training scripts, specify the compute target you want to use for training. Azure Machine Learning will automatically provision the required compute resources and execute the training job on the specified compute target.

3. Azure Container Instances:

Azure Container Instances (ACI) is a serverless container service that allows you to deploy and run containerized applications without managing the underlying infrastructure. ACI is a straightforward option for running batch workloads that can be containerized. To configure compute using Azure Container Instances, follow these steps:

1. Create an ACI: Start by creating an ACI instance in the Azure portal. Specify the container image, CPU, and memory requirements for the ACI instance.
2. Deploy the container: Once the ACI instance is created, deploy your container to the instance. Make sure your container has the necessary scripts and dependencies to execute the batch workload.
3. Scale as needed: ACI lets you easily scale the number of containers based on workload demands. You can increase or decrease the number of ACI instances depending on your batch processing requirements.

Conclusion:

Configuring compute for a batch deployment is an integral part of designing and implementing a data science solution on Azure. Azure provides several options, such as Azure Batch service, Azure Machine Learning compute, and Azure Container Instances, to configure and manage compute resources for batch workloads. By choosing the right compute option and properly configuring it, you can ensure efficient execution of your batch processing tasks, enabling faster data insights and improved decision-making.
