Introduction
Explore the core concept of microservices as independently deployable modules that enable faster deployment and modular system design. Understand the benefits of decoupling services, deployment using Docker containers, and how microservices compare to deployment monoliths. This lesson provides foundational knowledge to evaluate the applicability of microservices and the challenges involved.
We'll cover the following...
