Customizable policies help us determine how scaling should occur. In enterprise environments such as healthcare or banking with numerous instances running different applications, customizable policies allow appropriate scaling. For critical servers, we can set up a higher number of new instances to scale out to prevent downtime. For less critical servers that perform simple tasks such as file copying, we can use customizable policies to scale out minimal instances to avoid unnecessary expenses or cloud costs. Regarding integration, there are some disadvantages in AWS where certain availability zones or regions experience glitches. This can cause production halts because of problems on Amazon's side. In particular regions, when integrating Amazon EC2 Auto Scaling or other services, there might be delays in creating new Amazon EC2 instances, sometimes becoming inefficient.

The auto scaling feature is beneficial. Users don't need Terraform or another tool to automate this kind of situation. Obviously, if something bigger is required, another tool would be necessary, but 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. It is straightforward because all the tools at AWS can be visualized. Users can interact with this in a visual way without needing to use the terminal for configuration. The documentation is very straightforward, and if someone understands the concept of other virtual machines, transitioning to Amazon EC2 Auto Scaling is simple. The service offers 99.9999% availability. We have high availability, and I haven't experienced any downtime during my usage periods.

Amazon should provide more detailed training materials for people who are just starting to work with Amazon EC2 Auto Scaling. Documentation should be provided according to region. For example, in India, it should be available in Hindi or English, but the language or tone of communication needs to be adapted for the Indian market. The white papers or documentation should be provided in a simpler manner, rather than following a complex structure.
