Azure Spring Apps retirement announcement

  • Article

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.

Timeline

Azure Spring Apps, including the Standard consumption and dedicated (currently in Public Preview only), Basic, Standard, and Enterprise plans, will be retired through a two-phased retirement plan:

  • On September 30, 2024, the Standard consumption and dedicated plan (preview) will enter a six-month retirement period and will be retired on March 31, 2025.
  • In mid-March 2025, all other Azure Spring Apps plans, including Basic, Standard, and Enterprise plans, will enter a three-year retirement period and will be retired on March 31, 2028.

Migration recommendation

To ensure that you maintain high performance and achieve scalability, flexibility, and cost-efficiency for your business, we recommend Azure Container Apps as the primary service for your migration of workloads running on Azure Spring Apps. If you're using the Azure Spring Apps Enterprise plan, Azure Container Apps remains the most recommended destination. However, if you prefer to continue using Tanzu, AKS is a better choice, enabling you to host Tanzu components yourself with full control and capability over them.

Azure Container Apps is a fully managed, serverless container service for polyglot apps and offers enhanced Java features to help you manage, monitor, and troubleshoot Java apps at scale.

Key Features of Azure Container Apps:

  • Fully managed, serverless container platform
  • Scale to zero capability
  • Open-source foundation and add-ons
  • Enhanced Java support
    • Managed Spring components support (Eureka Server, Config Server, Spring Boot Admin)
    • Built-in JVM metrics
    • Diagnostics for Java apps

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.

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 with Azure Spring Apps Enterprise?

If you have interest in obtaining or continuing Spring commercial support and using Tanzu components, the recommended migration destination is AKS. Work with your Broadcom sales representative to explore how to purchase and run Tanzu on AKS.
