Spring Boot and Spring Cloud remain the dominant toolkit for Java microservices, providing service discovery, configuration management, and circuit breaker patterns needed for resilient distributed systems.
Clear service boundaries aligned to business domains, combined with API-first design and proper observability (distributed tracing, centralized logging), separate microservices architectures that deliver genuine agility from those that just add distributed-systems complexity without the benefits.
Cantonet Technologies designs Java microservices architectures with these fundamentals as prerequisites, not afterthoughts.
