What are the limitations associated with using Microservices?

Using Microservices architecture indeed presents several challenges, particularly related to governance, security, and discoverability.

Governance becomes complex in a microservices environment because multiple services may be developed and managed by different teams, leading to inconsistencies in compliance, version control, and data management. The decentralized nature of microservices requires a more sophisticated oversight mechanism to ensure that all services adhere to organizational policies and standards.

Security is another significant concern. Each microservice can have its own security protocols, and maintaining consistent security practices across numerous services can be challenging. This decentralization increases the risk of vulnerabilities, as each service may be an entry point for potential attacks. Ensuring secure communication between services also adds complexity.

Discoverability relates to the challenge of locating and integrating various microservices within an ecosystem. As the number of microservices grows, it can become difficult for developers and systems to find and utilize the appropriate services, especially if there is no established registry or documentation for the available services.

In contrast, enhanced scalability and flexibility, improved automation capabilities, and reduced resource usage typically are benefits of microservices, not limitations. Therefore, the identification of governance, security, and discoverability challenges as limitations accurately reflects the complexities associated with microservices architecture.
