Description

Introduction
Microservices architecture introduces unique challenges for CI/CD pipelines, including managing dependencies, coordinating service updates, and ensuring system reliability. This course explores how to utilize CircleCI to streamline the deployment of microservices, enabling rapid, reliable, and consistent delivery across distributed systems.

Prerequisites

• Familiarity with microservices architecture
• Basic understanding of CI/CD workflows and CircleCI
• Knowledge of Docker and container orchestration tools (e.g., Kubernetes)
