-- For scalability and portability, both the frontend and backend are containerized using Docker and can be spun-up easily using docker-compose.
-- Ansible playbooks and roles are used for automating the service setup & infrastructure creation of single (or multiple) EC2 on AWS. They are used for:
-    - Creation of a security group (with relevant properties) for EC2 instances
-    - Creation of EC2 instances & attaching of the defined security group
+- For scalability and portability, both the frontend and backend are containerized using Docker and can be spun-up easily using docker-compose and can be orchestrated using the Kubernetes (the manifest files have been provided).
+- Terraform is used for Infrastructure creation and Ansible playbooks and roles are used for configuring EC2 instances created on AWS providing:
     - Installation of Docker on those instances
     - Running of the url-shortener service through user input
