There is no evidence here to establish that one deployment method stopped a particular author’s 3 AM incidents. That claim needs incident records and deployment history. What can be established is how six common Spring Boot deployment paths differ—and which lifecycle controls help prevent failed requests during a rollout. For many teams, the best starting point is the simplest approach they can operate reliably; choose more orchestration only when its controls solve a real need.
How do you choose a Spring Boot deployment method?
Choose based on what your team needs to operate, not on a promise that a platform will eliminate incidents. Spring Boot’s executable JAR is designed to run in multiple environments, while cloud platforms can provide their own process or buildpack layer. Keep the Java runtime and configuration consistent as the application moves between environments (Spring Boot: Deploying to the Cloud).

Spring’s topical Kubernetes guide attributes Kubernetes use in a Spring environment to 65% of respondents in the 2024 State of Spring Survey. That is a survey result, not a current estimate of all Spring developers or evidence that Kubernetes is more reliable (Spring: Spring on Kubernetes).

What are the six deployment options?
| Approach | What it provides | What the team still needs to own |
|---|---|---|
| Executable JAR launched on a VM | A deployable Spring Boot artifact run with Java. | Host lifecycle, process supervision, deployment, and recovery. |
| Executable JAR managed by systemd | Operating-system service management and startup on boot. | Host maintenance, deployment orchestration, and traffic management. |
| Container image | A packaged application run by a container runtime. | Image build and promotion, runtime or platform operations, configuration, and lifecycle handling. |
| Kubernetes | Cluster-level orchestration and service lifecycle controls. | Cluster operation and configuration of the objects and traffic/shutdown behavior the application depends on. |
| Cloud Foundry | A platform-managed application deployment path. | Platform-specific configuration, health, logs, sizing, and recovery checks. |
| AWS Elastic Beanstalk | A managed deployment path for Java applications, with Java SE and Tomcat choices. | Platform configuration, health, logs, resource sizing, deployment behavior, and recovery. |
1. Executable JAR launched directly on a VM
The direct route is to run the executable artifact with java -jar. It is straightforward, but a command by itself is not a complete production process strategy: decide how the application starts after a host reboot, how a failed process is handled, and how a release is replaced or reversed. Spring Boot documents executable JAR and service deployment modes in its versioned 3.2.5 reference; check the documentation for the version your application actually uses before copying details (Spring Boot 3.2.5 deployment reference).
2. Executable JAR managed by systemd
On Linux, systemd can manage a Spring Boot service and start it at boot. This adds operating-system service management, but it does not provide a deployment orchestrator or take responsibility for the host. The Spring Boot 3.2.5 reference also documents init.d service support; select a service mode that fits the target operating system and verify it against the application’s Spring Boot version (Spring Boot 3.2.5 deployment reference).
3. Container image
A container image packages the application for a container runtime. Spring’s guides show Dockerfile-based builds and Maven or Gradle build-plugin routes (Spring Boot with Docker; Spring Boot Kubernetes guide). Packaging in an image can make the artifact easier to move between compatible environments, but it does not itself decide how traffic drains or how failed deployments are rolled back. Spring’s Docker guide is introductory, not an exhaustive production hardening or operations checklist.

Kubernetes adds orchestration and service-level lifecycle controls, but it also requires a cluster, kubectl, and a team able to manage the relevant platform objects and behaviors. It is a fit when the team needs those controls and can operate them—not simply because the application runs in a container (Spring Boot Kubernetes guide).
5. Cloud Foundry
Cloud Foundry can supply a platform-managed process and buildpack layer for an application. That shifts some infrastructure and process work to the platform; it does not remove the need to check application configuration, health, logs, sizing, deployment behavior, and recovery (Spring Boot: Deploying to the Cloud).
6. AWS Elastic Beanstalk
Elastic Beanstalk documents separate Java SE and Tomcat application paths; its Java SE option supports JAR deployments, while Tomcat is relevant to WAR applications. Confirm the platform branch and current availability for the target environment because AWS’s platform versions can change (AWS Java deployment guide; AWS Java quickstart). As with other managed platforms, provider-managed infrastructure does not replace application-level checks or a tested recovery procedure.
Rank #4
How do you prevent failed requests during a Spring Boot deployment?
Health checks and graceful shutdown solve different parts of a deployment. A health signal helps a platform decide whether an instance should receive traffic; graceful shutdown gives requests already in progress time to finish. During Kubernetes termination, pod shutdown activities can run concurrently, so traffic may briefly still reach a pod that has begun shutting down.

Configure readiness and traffic removal, then use a pre-stop delay so routing can catch up. Spring says the delay varies by deployment and should be at least as long as the longest in-flight request.
- Allow the process to stop gracefully. After the pre-stop hook completes, Kubernetes sends SIGTERM. Spring graceful shutdown can then allow in-flight requests to complete; the topical guide shows
server.shutdown=gracefulas the relevant Spring setting (Spring: Spring on Kubernetes). - Set enough termination time. Spring’s cloud guide describes Kubernetes’ default termination grace period as 30 seconds. Increase
terminationGracePeriodSecondsif the application’s shutdown can take longer. The required time depends on the deployment and request duration (Spring Boot: Deploying to the Cloud). - Keep health and shutdown coordinated. Spring warns not to rely on its graceful-shutdown period alone: the platform does not receive liveness data while the application is shutting down. Ensure the traffic-removal sequence and process termination window work together.
The Kubernetes guide uses broad Actuator endpoint exposure in an instructional example. Do not copy that exposure into production without a security review; expose only the endpoints needed and protect them appropriately (Spring: Spring on Kubernetes).
Quick Recap
What should you verify before choosing a deployment path?
- Confirm the Java and Spring Boot versions used in each environment, and consult documentation for those versions rather than assuming a versioned reference applies unchanged.
- Trace a release from artifact build through promotion and rollback; retain a clear link between the deployed artifact and its source revision.
- Test restart, failed health check, host or platform replacement, and rollback behavior—not only the successful deployment path.
- Check how secrets and environment-specific configuration reach the app, and verify that logs and health signals are usable by the on-call team.
- For a managed service, establish what the provider operates and what remains your team’s responsibility; verify platform versions and availability for the target region and environment.
- For Kubernetes, rehearse traffic removal, pre-stop timing, SIGTERM handling, and termination grace period with requests that reflect the application’s longest realistic in-flight work.
