Microservices with Spring Cloud
Leverage the power of Spring to create resilient microservices
Topic: Software Development
More people than ever want to create microservices-based architecture. But with the increasing complexity of these solutions, there’s a need for tools that allow Java developers to tackle distributed system issues.
Join expert Marcin Grzejszczak to explore one of these mature tools: Spring Cloud, a Spring Boot–based tool set. Constantly adapting to the requirements of modern software development, Spring Cloud allows you to apply complex distributed system patterns with a one-liner or just convention. In just three hours, you’ll learn the basics of Spring Cloud and how to apply it in your systems.
What you'll learn-and how you can apply it
By the end of this live, hands-on, online course, you’ll understand:
- What Spring Cloud is and how to apply it in your project
- How to communicate between services via HTTP and messaging
- How to gather metrics and perform latency analysis of your applications
And you’ll be able to:
- Write Spring Cloud microservices
- Use Spring Cloud’s service discovery integration to discover instances of your applications
- Gather metrics with Micrometer and perform latency analysis and tracing with Spring Cloud Sleuth
This training course is for you because...
- You’re a Java developer.
- You work with microservices.
- You want to become a microservices developer.
- General knowledge of Java
- A basic understanding of Spring Boot, Spring Web MVC, and Git
- A machine with have the following installed: Git, JDK 8, Curl / wget / httpie or any other application to perform HTTP requests, Docker, Docker Compose
- Watch “Using ‘Twelve-Factor App’ Style Configuration,” “Giving Your Microservice a REST,” and “Developing Web Applications” (video chapters, 1h 37m)
