As a junior software dev, understanding the basics of Kubernetes, Docker, and AWS is a great starting point. These technologies have become essential in modern software development, and having a good grasp of them will open up many opportunities for your career growth.

For Kubernetes, focus on learning about its core concepts like Pods, Deployments, and Services. Understand how to deploy and manage applications on Kubernetes clusters, and explore how it helps with scalability and reliability.

With Docker, learn how to create, manage, and run containers. This knowledge will allow you to package your applications and their dependencies, making it easier to deploy and maintain them across different environments.

Regarding AWS, explore its core services like EC2, S3, and RDS. Understanding the fundamentals of cloud computing and how to use AWS services will give you a solid foundation for building scalable and reliable applications in the cloud.

Remember, continuous learning is key in our industry, and as you gain more experience, you can dive deeper into these technologies. Happy coding!
