Azure Spring Apps retirement announcement

Azure Spring Apps is a fully managed service for running Java Spring applications, jointly built by Microsoft and VMware by Broadcom. After careful consideration and analysis, Microsoft and Broadcom have made the difficult decision to retire the Azure Spring Apps service. We recommend Azure Container Apps as the primary service for your migration of workloads running on Azure Spring Apps. Azure Container Apps is a strong and enterprise ready platform that provides fully managed, serverless container service for polyglot apps and enhanced Java features to help you manage, monitor, and troubleshoot Java apps at scale.

We're committed to supporting you with a long-term platform with migration tools, expert resources, and technical support through the end of the service.

What is the migration timeline?

Existing customers are required to migrate their Azure Spring Apps Standard consumption and dedicated workloads to Azure Container Apps by March 31, 2025. Customers on Basic, Standard, and Enterprise plans are required to complete this transition by March 31, 2028. Azure Spring Apps will be entirely retired by March 31, 2028.

Will Azure Spring Apps still allow new customer sign-ups?

For Azure Spring Apps Standard consumption and dedicated plan (preview), new customers will no longer be able to sign up for the service after September 30, 2024, while existing customers will remain operational until these plans are retired on March 31, 2025.

Will Microsoft continue to support my current workload?

Yes, support will continue for your workloads on Azure Spring Apps until the retirement date. You'll continue to receive SLA assurance, infrastructure updates/maintenance (VM and AKS), management of OSS/Tanzu components, and updates for container images of your apps including base OS, runtime (JDK, dotnet runtime, and so on), and APM agents. You can still raise support tickets as usual for prompt assistance through the end of the service.

Will Azure Spring Apps provide any new features during the retirement period?

No, we won't take up any feature requests from customers and won't be building any features in the Azure Spring Apps service. Instead, we'll prioritize new features and enhancements on Azure Container Apps.

What will happen after retirement date?

After March 31, 2025, the Azure Spring Apps Standard consumption and dedicated plan (preview) will be completely discontinued. As a result, you will no longer receive support and access to your workloads and Azure Spring Apps services.

After March 31, 2028, Azure Spring Apps Basic, Standard and Enterprise plans will be completely discontinued. As a result, you will no longer receive support and access to your workloads and Azure Spring Apps services. We strongly suggest you migrate your workloads to Azure Container Apps by March 31, 2028.

Does Microsoft Container Apps offer feature parity with Azure Spring Apps?

Customers should be able to achieve most of the desired capabilities to host their Spring applications on Azure Container Apps. Managed Spring components, Java metrics, and diagnostics support are available for you to use on Azure Container Apps. For more information, see Java on Azure Container Apps overview. If you have any questions, open a support ticket from the Azure portal or open an issue in the azure-container-apps repository on GitHub.

If you have interest in obtaining or continuing Spring commercial support and using Tanzu components, you can download the components and run them as JAR files on top of Azure Container Apps. Please work with your Broadcom sales to explore running Tanzu Platform Spring Essentials on top of Azure Container Apps.

Will Microsoft Azure Container Apps be available in the same Azure regions as Azure Spring Apps?

For the Standard consumption and dedicated plan (preview), Azure Container Apps and Azure Spring Apps are available in the same regions.

Azure Container Apps will be available in the same Azure regions as Azure Spring Apps for customers under the Basic, Standard, and Enterprise plans before the migration starts in March 2025.

Are there pricing differences across Microsoft solutions?

Azure Spring Apps operates on a consumption-based model with a basic unit where you only pay for vCPU and memory for your apps.

Azure Container Apps offers the following two pricing models:

• A consumption model billed based on per-second resource allocation (on VCPU and memory) and requests.
• A dedicated model with a single tenancy guarantee, access to specialized hardware, and more predictable pricing.

Billing for the dedicated plan is based on the number of vCPU seconds and gibibyte (GiB) seconds allocated across Azure Container App instances. Azure Container Apps also provides savings plan.

The costs for Microsoft solutions will vary based on their pricing model and optimizations that can be enabled. We recommend using the Azure Pricing Calculator, which provides details on meters, usage prices, and available savings plans to accurately assess anticipated costs.

What is the impact for customers using Tanzu Components within Azure Spring Apps Enterprise?

If you're interested in obtaining or continuing Spring commercial support and using Tanzu Components while migrating to Azure Container Apps, you can download the components and run them as JAR files on top of Azure Container Apps. For more information, please work with your Broadcom sales contact.
