JVM software architecture
A good architecture rarely draws attention to itself. You tend to measure it by how fast your teams ship without worrying they’ll break something. LAJVM designs and evolves JVM architectures built to last: we turn your business constraints and your scaling needs into reasoned, documented decisions that are realistic to put in place with the resources you actually have.
Where we operate
Architecture design: Microservices, modular monolith, hexagonal architecture, event-driven, CQRS: we start from your context to pick the style that fits, and we keep complexity to what’s genuinely needed. An over-split system costs as much as an over-monolithic one.
Modernisation and migration: Gradually moving out of a monolith, going from Java 8 to a recent LTS, introducing Kotlin, shifting to cloud-native. We favour incremental paths that deliver value along the way over a risky big-bang switch.
Distributed systems: Messaging and streaming with Kafka, data consistency, idempotency, resilience, observability. We design with failures in mind, not just the ideal path.
Platform and cloud-native: Docker containerisation, Kubernetes orchestration, deployment on AWS or Azure, infrastructure as code and CI/CD.
Spring Boot or Ktor
We work daily with both of the main JVM foundations. Spring Boot remains the reference for enterprise applications, with a rich, well-tooled ecosystem. Ktor, lighter and idiomatic in Kotlin, is built for reactive services and coroutines. The right choice depends on your team, your performance constraints and the ecosystem you need, and we help you make it without bias.
How we work
We start by understanding the business and where the product is heading, because architecture can’t be decided in the abstract. The structural choices are captured as ADRs, the short notes that record why a given decision was made. When a point carries real risk, we prototype it before committing. And we design with your teams rather than for them: an architecture nobody on your side understands won’t survive the first surprise.
What you keep
- A clear target architecture, documented and shared across the teams.
- The structural decisions traced and justified (ADRs).
- A realistic, staged implementation path.
- Teams aligned and self-sufficient on the choices that commit them.
