in28Minutes Learning Roadmap

My Views - Updated July 2019

Architectures are heading towards Microservices and Cloud!
Spring Boot is the most popular framework for developing Microservices
Spring Cloud provides great options to developing Cloud Native Applications. How well it does is yet to be seen!
Staying Cloud Neutral is becoming out of fashion
As a aspiration web programmer, I recommend to learn
- Java/Python - Be an expert at your language.
- Basics of Design - 4 Principles of Simple Design
- Be good at your IDE - Eclipse.
- Understand the build tool - Maven.
- Build one web application with JSP Servlets - Its great to know the basics.
- Build one web application with Spring MVC.
- Understand Spring and Spring Boot in depth. The more you understand them the more you would love them.
- Build REST Services with Spring MVC.
- Get comfortable with Frontend Frameworks.
If you want to move further ahead
- Understand Microservices architectures! Start with Spring Cloud and AWS.
- Understand Cloud! Start with AWS or Azure.
- Understand Containerization - Start with Docker.
- Understand Functional and Reactive Programming.
- Understand Kubernetes
- Understand BigData and Analytics - Start with Hadoop.
- Understand Messaging - Kafka, AMQP and JMS.
- Understand Continuous Integration, Delivery and DevOps.
