Not sure which of your posts on this i should reply on however, this is covered in the AWS documentation:
While Amazon RDS doesn't support some features of SQL Server, you can run SQL Server components in an Amazon EC2 instances with EBS storage, pursuant to Microsoft licensing policies. This includes components such as SQL Server Analysis Services, SQL Server Integration Services, SQL Server Reporting Services, Data Quality Services, and Master Data Services.
So what actually do you mean by deploying your SSIS package? If you want to use your RDS instance as a data source or destination that's possible, however you can't use the RDS instance to run the SSIS services. If you need a SQL instance that supports these services in AWS you will need to launch a EC2 instance with either a embedded SQL server installation in its AMI or install SQL server on your EC2 instance.
