I need someone with experience with AWS, S3, and EFS to consult me and make architecture recommendations on what AWS services to launch based on project objectives. This will be ongoing for several projects. I'll also rely upon you to guide me in configuring and setting up services so that I am able to SSH in and deploy my programs. Two thing I need assistance with now are: 1) How to effectively migrate 1TB of database stored in an EC2 AMI from one AWS account to another. 2) I need assistance with choosing which services to launch in order to run a web application that can efficiently search and retrieve files to be viewed on the web. I will provide further details upon hiring the right person but the above should give you an idea of what I'm looking to do.
