Frequently asked question
Explore the response to frequently asked questions to find the information you’re looking for.
Java applications can integrate AI through frameworks, APIs, and services for large language models, enabling features such as intelligent search, automated workflows, and AI-powered assistants.
Modernization is worth considering when legacy systems face performance limitations, security risks, rising maintenance costs, or difficulties integrating with modern platforms. The approach may include framework upgrades, refactoring, or migration to cloud-native architecture.
Java microservices divide applications into independently deployable services, allowing teams to scale specific components, isolate failures, and update functionality more flexibly. Effective implementation requires suitable service communication, monitoring, and deployment practices.
Security and reliability are supported through secure coding practices, dependency updates, automated testing, access controls, vulnerability assessments, and continuous monitoring throughout the development lifecycle.
