Without wasting any more of your time, here is a list of the best online courses you can buy on Udemy sales in 2023. The course is listed in no particular order but I highly recommend buying a Docker course as this is one of the most important tools for cloud-native development.

1. 100 Days of Code — The Complete Python Pro Bootcamp for 2023

3. 20 Web Projects With Vanilla JavaScript

Nobody explains project like Brad Traversy do and that’s why I love his courses. He has some impressive videos on YouTube and that’s how I discovered it but from them, I have become a huge fan of his voice and clear teaching style.

4. Docker & Kubernetes: The Practical Guide

There is no doubt that Docker is an in-demand skill and probably the #1 tool you should learn in 2023. While there are many great Docker courses on Udemy this course from Maximillan Scwarzmull is most complete and up-to-date.

5. Java Multithreading, Concurrency, and Performance Optimization

Multithreading and Concurrency is one of the most sought after skills for Java developers. There is a high demand for Java developers who understand Multithreading and Concurrency well, but at the same time, this is one of the difficult topics to master.

If you want to take your Concurrency skills to the next level and want to become an expert in Multithreading, Concurrency, and Parallel programming in Java, with a strong emphasis on high performance, then I highly recommend this course to you.

There is a reason I kept it in the first position because this is probably the most important course on this list and highly recommend every Java developer to go through it.

9. Multithreading and Parallel Computing in Java

This is another awesome Java Concurrency and Multithreading course from Udemy but it’s not free. Its normal price is around $200 but you can get it for just $9.99 on several of Udemy’s online sales, which is almost free.

The course is exhaustive as compared to the previous course and covers more topics and patterns with some real-life examples.

Apart from the basics of multi-threading like threads, lock, synchronization, blocking, etc, you will learn about Concurrent Collections which can simplify some concurrency design patterns like producer-consumer patterns.

Apart from Producer-Consumer, this course also explains the Dining Philosopher Problem and demonstrates two simulation projects i.e. Student Libary Simulation and Minor Game Simulation, which will allow you to apply the knowledge you learn.

13. Clean Code

Coding is an art and not everybody can write code that can stand the test of time. The code is easier to read and extend. The code which is robust and handles errors gracefully, the code which looks like a flowing river. Yes, I am talking about clean code.

14. Learn DevOps: The Complete Kubernetes Course

Along with Docker, Kubernetes is another tool that I am learning and recommending to all senior developers. Kubernetes take the deployment and scalability to another level and given the increased push for cloud-native development, you will need to learn Kubernetes sooner or later as a full stack developer.

If you want to pass the AWS Cloud Practitioner exam in one week and looking for one, solid, online courses which cover everything like exam topics, have quizzes and practice test for final preparation then you must join this Ultimate AWS Cloud Practitioner course by Stephane Maarek on Udemy.

I really loved this course and it superbly structured, up-to-date, and full of information which will not only help you to pass the AWS Cloud Practitioner certification but also work in any AWS environment.

If you don’t know Stéphane Maarek is one of the best AWS instructors on Udemy, an AWS Hero, and he has more than 9 AWS and Cloud certifications which means he has gone through the path himself. He even scored 980/1000 in one of the AWS exams which is phenomenal.

I highly recommend this course to anyone who wants to become a certified AWS cloud practitioner.
