Java Enterprise Development

Reliable backend systems for mission-critical requirements

Proven enterprise backend platform

The backbone of your digital infrastructure

Java has been the leading platform for mission-critical backend systems for over two decades – and for good reason. With Spring Boot as a modern framework, Jakarta EE as an industry standard and unparalleled ecosystem maturity, Java delivers the stability, scalability and security that DACH companies expect for their business-critical applications.

We develop Java backend systems that process millions of transactions, implement complex business logic and seamlessly integrate into existing IT landscapes. From modernizing monolithic legacy systems into cloud-native microservices architectures to building new API platforms, we support you with deep Java expertise and practice-oriented architecture consulting.

Why Java Enterprise with Medienstürmer

Enterprise-Grade Reliability

Java applications run in the most critical environments worldwide – from banks and insurance companies to industrial enterprises. The platform offers proven stability, comprehensive error handling and a mature security model.

Ecosystem Maturity

The Java ecosystem offers proven libraries and frameworks for virtually every requirement: from database access to messaging and machine learning. This maturity accelerates development and minimizes technical risk.

Horizontal Scalability

Java microservices with Spring Boot and containerized deployments scale horizontally on Kubernetes clusters. Whether 100 or 100,000 concurrent users – your architecture grows elastically with your requirements.

Expertise

Microservices Architecture

We design and implement microservices with Spring Boot that communicate via REST and gRPC APIs. Service discovery, circuit breakers, distributed tracing and event-driven architecture ensure resilient, loosely coupled systems that can be deployed and scaled independently.

API Development & Integration

We develop RESTful APIs and GraphQL interfaces that expose your business logic to frontend applications, mobile apps and third parties. API gateway configuration, OpenAPI documentation and versioning strategies are part of our standard scope.

Legacy Modernization

We modernize existing Java EE and J2EE monoliths step by step into current Spring Boot microservices. Using the Strangler Fig pattern approach, we replace legacy components piece by piece without jeopardizing ongoing operations.

Cloud-Native Deployment

We containerize your Java applications with Docker, orchestrate them with Kubernetes and deploy to AWS, Azure or GCP. Infrastructure as Code with Terraform, Helm charts and automated pipelines ensure reproducible, secure deployments.

How It Works

Requirements & Architecture

We analyze your business and technical requirements and design a backend architecture that optimally maps your business processes. Domain-driven design, bounded contexts and API contracts form the foundation.

Backend Development

In agile sprints, we implement the microservices, database schemas and integration layers. Clean code principles, SOLID design and comprehensive unit and integration tests ensure the highest code quality.

Integration & Testing

We integrate your backend services with existing systems, external APIs and frontend applications. Load tests, security audits and contract testing ensure that your application is production-ready.

Go-Live & Operations

We support the go-live with blue-green deployments, configure monitoring and alerting with Prometheus and Grafana and establish runbooks for operations. On request, we also take over ongoing maintenance and further development.

Frequently Asked Questions

Java is actively developed and receives new features every six months. Modern Java versions offer pattern matching, records, virtual threads and much more. Combined with Spring Boot, Java remains the most productive and secure platform for enterprise backend development.

Spring Boot provides an opinionated approach with auto-configuration, embedded servers and a vast ecosystem of starter dependencies. Development is faster, testability is excellent and the community is very active. For most new projects, we recommend Spring Boot.

We pursue an incremental approach using the Strangler Fig pattern. New features are developed as modern microservices, while existing functions are gradually extracted and modernized. This avoids a risky big-bang rewrite and lets you benefit from modern technologies early on.

With Spring Boot, GraalVM native images and optimized container configuration, Java applications achieve fast startup times and efficient memory usage in cloud environments. Kubernetes orchestration enables elastic scaling and automatic failover for highly available systems.
