Learn about MSA (Microservices Architecture)

Hello, today we will explore MSA (Microservices Architecture).

Explanation

MSA is a hot topic in the software development field, focusing on an architectural approach. This article will explain what MSA is and discuss Advantages and Disadvantages. MSA, or Microservices Architecture, consists of small, independent services that make up a software architecture. Each service operates as an independent process and communicates with other services using APIs, typically RESTful APIs.


Advantages

  • Name
    Service Independence
    Type
    Description

    Since each service can be independently developed, deployed, and scaled, the overall system's flexibility and diversity can be increased.

  • Name
    High Scalability
    Type
    Description

    By allowing individual services to scale independently, performance optimization and efficient resource usage can be managed on a per-service basis.

  • Name
    Easy Maintenance
    Type
    Description

    As the services consist of small functional units, maintenance is easier, and the impact of refactoring or changes in the technology stack can be minimized.

  • Name
    Fast Market Launch
    Type
    Description

    Developing and deploying each service independently eliminates the need to update the entire system at once, thus accelerating the market launch speed.

Disadvantages

  • Name
    Complex Inter-Service Communication
    Type
    Description

    When communication between services is required, API-based interactions are necessary, which can increase complexity.

  • Name
    Increased Management Burden
    Type
    Description

    As each service must be individually deployed and managed, the burden of environment configuration and infrastructure management may increase.

  • Name
    Data Consistency
    Type
    Description

    Since each service uses independent data, maintaining data consistency may require additional effort.

Summary

While MSA has high scalability and flexibility, which may involve more initial costs and considerations, it is a powerful architectural approach that can be applied to various fields. It is recommended to use MSA appropriately according to the system's size and requirements to achieve the best results.
