A Comprehensive Overview of Microservice Architecture and Its Technology Stack
This article provides a detailed introduction to microservice architecture, tracing its evolution from monolithic to distributed services, and enumerates the essential technologies—including service communication, API gateways, authentication, fault‑tolerance, logging, configuration management, containerization, orchestration, and CI/CD—that enable building scalable, resilient cloud‑native systems.
The author records their learning journey of microservice architecture, beginning with an introduction that highlights the growing complexity of software systems and the need for high performance, scalability, and stability.
The evolution of software architecture is outlined in three stages: monolithic applications, vertical splitting, and distributed services, each with its advantages and drawbacks.
Microservice architecture is then presented as the mature form of distributed systems, emphasizing its key characteristics such as high availability, scalability, low coupling, independent deployment, and language‑agnostic development, while also noting challenges like increased complexity and network overhead.
A comparison of architectural styles follows, covering SOA, centralized proxy (Nginx), client‑embedded discovery (Consul), and service‑mesh solutions, describing their discovery, load‑balancing, and governance capabilities.
The core technology stack for microservices is listed, including service communication (WebService, WCF, WebAPI), process communication (gRPC), API gateway (Ocelot), authentication/authorization (IdentityServer4), transient fault handling (Polly), distributed tracing, centralized logging (Exceptionless, ELK), configuration center (Apollo), distributed lock (Consul, Redis, Zookeeper), distributed transaction patterns (2PC, TCC, Saga), containerization (Docker), container orchestration (Kubernetes), and CI/CD pipelines (Jenkins).
The article concludes with a brief personal note encouraging continuous learning and improvement.
