Amplify Terminal or CLI via browser??

You'll need to use the Amplify CLI to enable analytics, but CloudShell might be a good option to do that within the browser. You'd need to set up the CLI within CloudShell (https://docs.amplify.aws/cli/start/install/), but it would mean you wouldn't need to set up a local environment.

The first answer by Ed is great and check this blog, but you might think of alternatives as well.

If you need to access the terminal or interact with the infrastructure directly, you would typically use other AWS services that provide such capabilities, such as AWS Elastic Beanstalk, AWS EC2 instances, AWS Elastic Container Service (ECS), or AWS Elastic Kubernetes Service (EKS).

AWS Elastic Beanstalk: AWS Elastic Beanstalk provides a platform-as-a-service (PaaS) environment where you can deploy and manage applications. It offers an environment with EC2 instances that you can access and configure using the Elastic Beanstalk CLI or AWS Management Console.

AWS EC2 Instances: If you need more control over the infrastructure, you can manually provision and manage EC2 instances. You can use SSH to access the terminal of these instances and install/configure the required software.

AWS ECS or EKS: If you are using containerized applications with Docker, you can use AWS ECS (Elastic Container Service) or EKS (Elastic Kubernetes Service) to manage your containers. In these cases, you would interact with the container clusters using container management tools like Docker CLI, ECS CLI, or kubectl (for EKS).

Remember that accessing the underlying infrastructure directly requires a good understanding of AWS services and security best practices. You should exercise caution and follow AWS's best practices for managing access to your resources.
