Java app development planning and framework selection

The best Java framework is the one that best meets the specific needs of your project. Our Java experts nail it down by analyzing all the relevant data points, including Java version compatibility, database integration needs, cloud platform requirements, API integrations, framework-specific features, and more to help you make the right tech choice.

  • Feasibility studies and business case validation
  • Solution framework analysis and selection
  • Requirements collection and business analysis
  • Cost, time, and ROI estimation

Java app architecture design

From advice to solution implementation, our Java solution architects select the optimal architecture to fit your project requirements and constraints. We tailor the architecture to your scalability, performance, and cost-efficiency needs, delivering key design documents that outline the chosen pattern.

  • Monolithic architecture

    A go-to unified architecture with one codebase, monolithic architecture is a wise choice for applications with predictable growth. With all system components sharing a code base, this architecture design pattern simplifies, streamlines, and accelerates development for your Java applications.

  • Client-server architecture

    If high reliability, easy maintainability, and inherent scalability are what float your Java app, client-server architecture is a safe bet. Thanks to reduced client complexity and efficient resource usage, it’s a good mesh for web applications and mobile platforms — and our developers have the expertise to maximize its potential.

  • Service-oriented architecture

    SOA makes it easier to respond to evolving business needs, allowing you to modify and replace individual services without systemic overhauls. With this architectural style, our developers build a service once and then reuse it across different systems, reducing your development time and cost.

  • Microservices architecture

    Unlike monolithic applications, microservices ones thrive on agility, allowing companies to scale and upgrade individual components as needed. This translates into faster release cycles, easier innovation, and greater tech flexibility for your business — a must-have for complex tech estates.

  • Reactive architecture

    Cut out for the demands of high-volume, asynchronous applications, the reactive architecture ensures your app stays responsive and resilient even under a heavy load. Our developers use the combination of Reactive Streams, Akka, and RxJava to ensure your app is not only fault-tolerant but also easier to maintain.

  • Lambda architecture

    Combining a traditional batch pipeline with a real-time stream pipeline, Lambda architecture is well-suited for Big data solutions with real-time data processing. Our development team takes the inherent complexity out of this architectural style, making sure your apps have both the speed and accuracy to handle massive datasets.

  • Serverless/FaaS architecture

    Under a serverless architecture, you pay for the resources your apps actually consume while also abstracting away the infrastructure. Relying on time-tested tools like AWS Lambda and Google Cloud Functions, we help you leverage this architectural pattern and make it pay off for your specific use case.
