Deploy large CPU and memory applications in Azure Spring Apps in the Enterprise plan

Note

The Basic, Standard, and Enterprise plans will be deprecated starting from mid-March, 2025, with a 3 year retirement period. We recommend transitioning to Azure Container Apps. For more information, see the Azure Spring Apps retirement announcement.

The Standard consumption and dedicated plan will be deprecated starting September 30, 2024, with a complete shutdown after six months. We recommend transitioning to Azure Container Apps. For more information, see Migrate Azure Spring Apps Standard consumption and dedicated plan to Azure Container Apps.

This article applies to: ❌ Basic/Standard ✔️ Enterprise

This article shows how to deploy large CPU and memory applications in Azure Spring Apps to support CPU intensive or memory intensive workloads. Support for large applications is currently available only in the Enterprise plan, which supports the CPU and memory combinations as shown in the following table.

CPU (cores)	Memory (GB)
4	16
6	24
8	32

Prerequisites

• An Azure subscription. If you don't have a subscription, create a free account before you begin.
• An Azure Spring Apps service instance.
• The Azure CLI. Install the Azure Spring Apps extension with the following command: az extension add --name spring.

Create a large CPU and memory application

You can use the Azure portal or the Azure CLI to create applications.

Azure portal

Use the following steps to create a large CPU and memory application using the Azure portal.

1. Go to your Azure Spring Apps service instance.

2. In the navigation pane, select Apps, and then select Create app.

3. On the Create App page, provide a name for App name and select the desired vCpu and Memory values for your application.

4. Select Create.

   

Azure CLI

The following command creates an application with the CPU set to eight core processors and memory set to 32 gigabytes.

az spring app create \
    --resource-group <resource-group-name> \
    --service <Azure-Spring-Apps-service-instance-name> \
    --name <Spring-app-name> \
    --cpu 8 \
    --memory 32Gi 

Scale up and down for large CPU and memory applications

To adjust your application's CPU and memory settings, you can use the Azure portal or Azure CLI commands.

Azure portal

Use the following steps to scale up or down a large CPU and memory application.

1. On the overview page of your app, select Scale up in the navigation pane.

2. Select the preferred vCpu and Memory values.

   

3. Select Save.

Azure CLI

The following command scales up an app to have high CPU and memory values.

az spring app scale \
    --resource-group <resource-group-name> \
    --service <Azure-Spring-Apps-service-instance-name> \
    --name <Spring-app-name> \
    --cpu 8 \
    --memory 32Gi 

The following command scales down an app to have low CPU and memory values.

az spring app scale \
    --resource-group <resource-group-name> \
    --service <Azure-Spring-Apps-service-instance-name> \
    --name <Spring-app-name> \
    --cpu 1 \
    --memory 2Gi
