Hi @Diwakar, learning DevOps is going to easier for you as you have already learned AWS. Learn different tools like Git, Docker, Jenkins, one of the configuration management tools(Ansible, Puppet, Satlkstack or Chef), Kubernetes.
Go through a few blogs:

https://www.edureka.co/blog/aws-certified-devops-engineer/
https://www.edureka.co/blog/docker-container-in-production-amazon-ecs/
A better approach would be to take up a DevOps AWS course which will systematically teach you about all DevOps tools with their integration and usage with AWS services.
