Microservices architecture is becoming popular due to its advantages like loose coupling, diverse tech stack, easy scalability, and faster development time. However, maintaining the overall application performance can become a challenge with increasing microservices count. This article provides best practices for high-performance microservices development, including choosing the best-fit technology stack, designing microservices using SOLID principles, and implementing effective communication and security measures. Good development practices and following these recommendations can lead to efficient and high-performance code for microservices architecture.
