To help you get started QlikTech provide some public AMI images with QlikView pre-installed, so you would only need your licences and some changes to the firewall rules and you’re up and running.
Overall my experience with AWS and QlikView has been good with many benefits in AWS such as the scaling and redundancy. Some things to watch out for are how are you going to get your data into the server? (QVD / QVW / CSV etc) and how to authenticate your users (if your IT won’t allow the server to connect to your company active directory).
I have a client on AWS now but am having trouble emailing reload failures from the QMC. I am trying to use Amazon SES for the SMTP server. I have authenticated the user to receive the email and am operating in Sandbox mode. As I understand it this gives us 200 emails a month which will be more than enough. I can send an email direct from the Amazon console to this user. The QMC indicates that we have not authenticated correctly. QlikView support indicated that QlikView Management COnsole works with TLS which appears to be needed by Amazon. QlikTech support indicated we would need to make changes to the Windows server.
