1. Decomposing Monolithic Applications: One of the biggest challenges in microservices architecture transformation is decomposing the monolithic application into independent microservices. The process often requires identifying different functional domains within the monolith and deciding which domain should become a separate microservice.
2. Service Discovery and Management: With the proliferation of microservices, discovering and managing them becomes a challenge. Service discovery solutions such as DNS or a centralized service registry are used to find and manage microservices. However, such tools are often complex and require careful configuration to guarantee availability and reliability.
3. Managing Infrastructure: Microservices rely heavily on infrastructure and are designed to run in a distributed environment. Setting up and managing infrastructure such as hosting, networking, security, and load balancing for multiple services is a challenge.
4. Testing and Monitoring: Microservices require a different approach to testing than monolithic applications. Traditional end-to-end testing is challenging because it requires testing multiple services in different environments. Similarly, monitoring and debugging distributed systems are also challenging due to the numerous points of failure and traffic routing.
5. Data Management: Unlike monolithic applications, where databases are often shared between different modules, microservices require individual databases for each service, increasing the need for data management.
6. Governance and Compliance: Microservices pose a challenge in governance and compliance because they are built and maintained by different teams with distinct ways of working. A unified governance and compliance framework must be developed to ensure consistency and compliance across the organization.
