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

84
+
85
+
### Are there pricing differences across Microsoft solutions?
86
+
Azure Spring Apps operates on a consumption-based model with a basic unit where you only pay for vCPU and memory for your apps.
87
+
Azure Container Apps offers two pricing models: 1) a consumption model, billed based on per-second resource allocation (on VCPU and memory) and requests. 2) 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.
88
+
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.
