[1] Project Introduction

Dante Cloud is the first microservices platform in China that supports both blocking and reactive services in parallel. Designed with Domain-Driven Design (DDD) principles, it focuses on "high-quality code, low security vulnerabilities". Based on the full spectrum of open-source technologies in the Spring ecosystem, it features highly modular and componentized design, supports authentication for smart TVs, IoT, and other connected devices, meets China's Level 3 Cybersecurity Classification Protection requirements, and includes a series of security systems such as interface national cryptographic digital envelope encryption and decryption. It is a multi-tenant microservices solution that can "implement both microservices and monolithic architectures with one codebase" for enterprise application systems.

[2] Project Philosophy

Dante Cloud has always adhered to the philosophy of "Simplicity, Efficiency, Inclusiveness, and Pragmatism." It utilizes various emerging or mainstream technologies in the microservices domain and its periphery for construction, continuously refining, discarding the rough and selecting the fine, and meticulously crafting. The goal is to build a product with high code quality, low maintenance investment, and strong security protection that can help users quickly bypass the stages of architectural technology selection and technical research exploration. It aims to reduce the high maintenance costs caused by potential hidden dangers such as security vulnerabilities, technical debt, and low-quality code in traditional projects. Like the meaning of its name, it hopes to bridge the past and the future during this period of industry transformation, assisting enterprises in their informatization construction and transformation.

The core focus of Dante Cloud is: 「High-quality system code」, 「Reasonable system architecture」, 「Low-coupled module division」, 「High-security system implementation」, 「Flexible functional expansion capabilities」, and 「Excellent microservices implementation」, rather than pursuing the richness of stacked business functions.

[3] Architectural Design

Besides providing a complete microservices architecture, Dante Cloud also supports running as a monolithic architecture. The microservices architecture and the monolithic architecture are not two separate codebases, nor are they two separate projects. They are a fully integrated single codebase. Users can choose to run in microservices mode or monolithic mode as needed. This is one of the biggest features of Dante Cloud microservices: "One Codebase, Two Architectures".

The microservices architecture based on Spring Boot and Spring Cloud has become the mainstream solution for enterprise application construction. However, it is undeniable that the infrastructure required to set up a microservices architecture is becoming increasingly numerous and complex. Just setting up a development and debugging environment on a development computer involves considerable complexity and resource requirements. For many applications, especially small ones in their early stages or with a small user base in the beginning, a single, front-end and back-end separated backend is often sufficient. There is no need to deploy a full set of microservices, which adds extra complexity.

Dante Cloud's feature of "One Codebase, Two Architectures" can help enterprises quickly build projects with a monolithic architecture in the early stages, facilitate local development for developers, and enable research on new technologies. As user scale grows and concurrency requirements increase in the later stages of the project, it can quickly and seamlessly migrate to a microservices architecture.

[4] Feature Introduction

The Dante Cloud demo system has been released. It currently includes an online version, a monolithic offline version (Docker), and a microservices image version. Welcome to experience and use it!
