“The era of merely asking AI and getting answers is over.” Now, AI acts on its own. 'Action-oriented AI agents' have emerged that read emails, check remaining annual leave in HR systems, schedule meetings, search internal documents to summarize information, and organize necessary images and links. What's surprising is that all of this can be created even if you're not a developer. By leveraging the Azure AI Agent platform and Microsoft's latest frameworks (Semantic Kernel, AutoGen, etc.), anyone can now build multi-agent systems deployable in actual work, without coding. Directly create 'working AI,' 'connected AI,' and 'AI that judges and moves on its own.' The future is no longer a distant story. It begins now, at your fingertips.

You can quickly and easily learn the basics of authentication and authorization through tutorials using Spring Boot, Spring Security, and JWT.
