We need two ecommerce sites hosted and managed by the same ecommerce framework to be installed on our cloud server running Centos 7. The same sites need to be responsive and be able to work on both web and mobile. We need the check out to work through Amazon or other methods independent of Amazon. The number of products are less than 20 now. We want the pages load fast and have fast response times. We need to choose an ecommerce framework that can do the above. This work needs to be done in the next few weeks. Thanks.
