Amazon EC2 Auto Scaling operates at a different level, working in parallel to efficiently manage workload distribution. Primarily, it focuses on orchestration rather than directly managing EC2 instances for deployment and configuration. It uses automated processes to deploy and manage ports, leveraging Application Load Balancers to effectively handle data communication and management.

The auto scaling feature is beneficial; users don't need Terraform or another tool to automate this kind of situation, and when configuring Amazon EC2 Auto Scaling without wanting to spend excessive money, it can be scaled up during peak demand times and scaled down during particular days or periods.

The tool is a simple solution. You can deploy a new virtual machine in minutes. You can select options like memory and core number and connect storage. It's great because it's simple and fast. You can build a virtual machine in minutes, do your experiments, and then uninstall it without paying for it when it's not in use.

Amazon EC2 Auto Scaling offers various benefits but lacks certain features for fine-grained customization compared to other cloud providers like GCP. Users are constrained by predefined instance families in EC2 when selecting instance types for scaling. Unlike GCP, where users can independently scale resources such as memory or CPU, EC2 doesn't offer this flexibility.
