AWS Machine Learning is a powerful tool that can be used for a variety of tasks, including predicting future events and identifying patterns in data. While the service does have a few limitations, it is generally free to use.
One limitation is that AWS Machine Learning is limited to using Amazon Web Services (AWS) resources. This means that if you want to use the service on a separate computer, you will need to purchase an AWS account.
Additionally, the service is limited to working with data that is stored in Amazon S3. If you want to work with data that is stored in other services, such as Microsoft Azure or Google Cloud Platform, you will need to use a different tool.
Overall, though there are some limitations, AWS Machine Learning is a powerful tool that can be used for a variety of tasks. While it is generally free to use, there are a few costs associated with using the service, such as the cost of an AWS account.
