Hi there! My name is Ali Gelenler. I'm here to help you learn event-driven microservices architecture by applying best practices for real-life challenges.

In this course, you will focus on the development of microservices. With the help of microservices you can independently develop and deploy your application components . You can also easily scale services according to each service's own resource needs, for example you can scale better and create more instances of a service that requires more requests.

When moving from a monolith application to microservices architecture, some challenges will arise as a result of having a distributed application and system. In this course you will learn how to deal with these challenges using event-driven architecture (EDA) architecture with Apache Kafka.

With an event-driven architecture;

- You will truly decouple the services and create resilient services because a service has no direct communication with other services
- You will use asynchronous/non-blocking communication between services
- You will use an event/state store (Kafka), and remove the state from the services for better scalability

Tanima: "This is one of the best course i ever had in udemy, instructor is super responsive and always deals with complex problem during the course, Thank you so much Professor i will always be grateful to you for this course, and will keep eye on your next course release."

The microservices patterns that you will be implementing are:
- Externalized configuration with Spring Cloud Config
- CQRS with Kafka and Elastic search
- Api versioning for versioning of Rest APIs
- Service Registration and Discovery with Spring Cloud and Netflix Eureka
- Api Gateway with Spring Cloud Gateway
- Circuit breaker with Spring Cloud Gateway and Resilience4j
- Rate limiting with Spring Cloud Gateway and Redis to use Redis as the Rate limiter
- Distributed tracing with SLF4J MDC, Spring Cloud Sleuth and Zipkin
- Log aggregation with ELK stack (Elasticsearch, Logstash and Kibana)
- Client side load balancing with Spring Cloud Load Balancer
- Database per Service
- Messaging between microservices using Kafka

You will also implement Spring Security Oauth 2.0 and OpenID connect protocols for Authentication and Authorization using Keycloak and JWT. The use of Oauth for authorization of services and OpenID connect for authentication is widely used in microservices archictecture with Spring boot security.

While introducing event-driven microservices, you will understand the basics of Apache Kafka by covering Kafka topics, Kafka partitions, Kafka consumer and producer APIs, Kafka admin client and Avro messaging.

There is also a reactive development section in this course which demonstrates querying elasticsearch reactively with Reactive Spring, WebFlux, WebClient and Reactive Thymeleaf. In this section you will learn how to use Spring Webflux and Spring reactive components to create an asynchronous flow between microservices.

You will be following a hands-on approach and be developing a project from scratch in which you will have multiple microservices surrounded with multiple modules to accomplish the specific tasks. So you will need to make your hands dirty in this course where I will be guiding you from start to finish. You will also find multiple choice quizes in each section to check your progress throughout the course.

At the end of the course you will not only understand the real life challenges of a distributed application with multiple services and components, but also you will be able to apply solutions to this challenges.

Ido Charar: "This course by Ali Gelenler is outstanding. It is not just about Spring Cloud with kafka and elastic. This course gives you much more knowledge around technologies related to Spring Cloud in particular and Cloud Computing in general. Among them are technologies like reactive programming, streaming, linux OS, security, Design Patterns and much much more. All the information is given in succinct but ingestable form, which allows you broaden your skills in shortest possible time. Very appreciate the investment in material, lecturer involvement, constant assistance and help to the students. Will recommend to take this course everyone who want to level up her/his skills."

For more detailed information on the progress of this course, you can check the introductory video and free lessons, and if you decide to enroll in this course, you are always welcome to ask and discuss the concepts and implementation details on Q/A and messages sections. I will guide you from start to finish to help you successfully complete the course and gain as much knowledge and experience as possible from this course.
