Microservices are increasingly crucial in software development. This course teaches the fundamentals of both monolithic and microservices architectures helping you understand when and how to use each approach. You'll learn through real-world examples including how companies like Twitter handle millions of users by transitioning to microservices. We begin by exploring monolithic architecture and the applications it best serves. Then we examine microservices architecture using case studies of companies that manage large data volumes to illustrate its practical applications.The course covers essential concepts including service communication through REST APIs message brokers and service meshes. You'll also learn how continuous integration and deployment (CI/CD) pipelines enable companies to update thousands of microservices daily. Additionally you’ll gain hands-on experience through guided exercises and detailed project breakdowns. These practical activities demonstrate how to design build and deploy microservices in real-world scenarios. By completing the course you’ll not only understand theoretical concepts but also acquire the ability to create scalable efficient systems tailored to modern software needs.This course equips you with the knowledge to make informed architectural decisions and implement modern deployment methods. Whether you're a developer expanding your skills or a software architect planning to transition between architectural patterns the course offers clear detailed lessons you can complete at your own pace.
